Patent Description:
The present disclosure relates to connectors for optical fibers, and in particular, but not exclusively, to connectors for duplex optical fiber cables.

In data communications systems, optical fiber systems having a plurality of optical fiber cables are frequently used to connect between communication nodes. Typically, the optical fiber cables include a pair of optical fibers known as duplex optical fiber cables, one for transmitting and one for receiving (typically, the receiving fiber is labeled A and the transmitting fiber is labeled B). The overall effect of the data communications cabling is that the transmitting cables B connect with receiving ports A, and the receiving cables A connect with transmitting ports B. However, during installation, it is not uncommon for the installer to get confused between the transmitting and receiving cables and a cross-over can occur such that the transmitting cables B are not connected with receiving port A, and vice versa. For many connector types, installers are prevented from simply unplugging the duplex cable connectors and reinserting them in another orientation because the connectors are unidirectional and therefore can only be inserted into the complementary receiving ports in one orientation. Thus, it is necessary for the installer to replace the existing cable or remove the connecting head from the fibers and effectively remanufacture the cable on site, which is very cumbersome and time consuming.

Another problem with duplex optical fiber cable connectors is that it can be difficult to remove the connector from the receiving port This is particularly true for panels having a high density of connectors, which means there is limited space around each connector. Thus, it can be difficult for a user to manipulate the locking levers when removing the connector from the panel.

<CIT> describes duplex connectors assemblies with a push/pull clip integrated with a cable boot that allows a user to apply a distal force to remove or insert the connector assembly into an adapter housing.

Accordingly, an improved optical fiber connector, particularly for duplex optical fiber cables, is desired.

In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the invention as defined by the appended claims.

As used herein, the terms "first," "second," and "third" may be used interchangeably to distinguish one component from another and do not necessarily signify sequence or importance of the individual components. As used herein, terms of approximation, such as "generally," or "about" include values within ten percent greater or less than the stated value. When used in the context of an angle or direction, such terms include within ten degrees greater or less than the stated angle or direction. For example, "generally vertical" includes directions within ten degrees of vertical in any direction, e.g., clockwise or counter-clockwise.

Referring now to the Figures, the present disclosure is generally directed to a connector for optical fibers. <FIG> illustrate an exemplary connector <NUM> including a housing <NUM>, a boot <NUM>, and a handle <NUM>. The connector <NUM> may engage with an optical fiber <NUM> extending from the housing <NUM> through the boot <NUM>.

In one or more embodiments, the housing <NUM> can include a plurality of pieces configured to engage with one another to form the housing <NUM>. For instance, the housing <NUM> can include two or more pieces that snap fit together in a releasable manner via snap fit connectors. The housing <NUM> can include a trailing end aperture (not illustrated) and leading end aperture(s) <NUM>. A section of optical fiber cable can be disposed within the housing <NUM> and extend at least partially between the trailing end aperture and the leading end aperture(s) <NUM>. In an embodiment, the optical fiber <NUM> can be inserted into the housing <NUM> through the trailing end aperture. The boot <NUM> can overlay a portion of the optical fiber <NUM> and a trailing portion <NUM> of the housing <NUM>. The boot <NUM> may provide stress relief to the optical fiber <NUM>, preventing undesirable stress loading of the optical fiber <NUM> at an interface with the housing <NUM>.

The optical fiber <NUM> can furcate inside the housing <NUM> into first and second optical fibers (not illustrated). The first optical fiber can exit the housing <NUM> via a first leading end aperture and the second optical fiber can exit the housing <NUM> via a second leading end aperture. The first optical fiber may correspond with a receiving fiber (A) and the second optical fiber may correspond with a transmitting fiber (B).

The first optical fiber may extend into a bore <NUM> formed in a first inner body <NUM> and the end of the first optical fiber can be connected to a first ferrule <NUM>. The first inner body <NUM> may protrude from the housing <NUM> via the first leading end aperture <NUM> of the housing <NUM>. In an embodiment, the first inner body <NUM> may be fixed with respect to the housing <NUM>. The first inner body <NUM> can include, for example, engagement portions (not illustrated) to secure the first inner body <NUM> to the housing <NUM>. The engagement portions may prevent extrusion of the first inner body <NUM> from the housing <NUM> and/or prevent rotation between the first inner body <NUM> and the housing <NUM>. Moreover, the engagement portions may maintain the first inner body <NUM> at a fixed relative position with respect to the housing <NUM>.

The first ferrule <NUM> may protrude out of the bore <NUM> formed in the first inner body <NUM>. The first ferrule <NUM> and/or first inner body <NUM> may generally define a leading edge <NUM> of the connector <NUM>. The leading edge <NUM> may be insertable into an optical fiber port (<FIG>), e.g., part of an optical fiber panel, to permit optical connection between the optical fiber <NUM> and another optical fiber (not illustrated) contained within or coupled to the panel.

The second optical fiber may extend into a bore <NUM> formed in a second inner body <NUM>. The end of the second optical fiber can be connected to a second ferrule <NUM> which protrudes from the bore <NUM>. The second inner body <NUM> may be fixed with respect to the housing <NUM>. The second inner body <NUM> can include engagement portions (not illustrated), similar to or different from the engagement portions previously described with respect to the first inner body <NUM>, to secure the second inner body <NUM> to the housing <NUM>. The engagement portions may prevent extrusion of the second inner body <NUM> from the housing <NUM> and/or prevent rotation between the second inner body <NUM> and the housing <NUM>. Moreover, the engagement portions may maintain the second inner body <NUM> at a fixed relative position with respect to the housing <NUM>.

In one or more embodiments, the housing <NUM> and the first and second inner bodies <NUM> and <NUM> may be formed from interconnected pieces. That is, for example, the first and second inner bodies <NUM> and <NUM> may be integral with the housing <NUM>. Alternatively, the first and second bodies <NUM> and <NUM> can include discrete components configured to engage with the housing <NUM>. For example, the first and second bodies <NUM> and <NUM> may be engageable with the housing <NUM>, e.g., upon snap fitting two or more pieces of the housing <NUM> to one another.

Connectors in accordance with one or more embodiments described herein may be capable of reversing polarity. That is, for example, the polarity of the first and second optical fibers, as seen with respect to the position of a latch (described in greater detail below), may be interchangeable. More specifically, the receiving fiber (A) and transmitting fiber (B) can be interchanged. In an embodiment, the receiving fiber (A) and transmitting fiber (B) can be switched relative to the housing <NUM>. For example, the housing <NUM> can have a removable surface through which the receiving fiber (A) and transmitting fiber (B) can be accessed to allow an operator to change the positions thereof. In another embodiment, the housing <NUM> can be removed from other components of the connector <NUM> (e.g., the boot <NUM>) and reinstalled in an inverted orientation (i.e., reverse polarity). The latch (described in greater detail below) can be coupled to the housing <NUM> (e.g., integral with the housing <NUM>) such that rotation of the housing <NUM> results in rotation of the latch. Through reversible polarity, the operator may adjust the connector(s) in situ, thereby reducing costs and allowing the operator to carry fewer redundant components.

As discussed above, the connector <NUM> may further include a latch <NUM> extending from the housing <NUM>. In an embodiment, the latch <NUM> can include a first latch <NUM> and a second latch <NUM>. The first latch <NUM> can correspond with the first inner body <NUM> and the second latch <NUM> can correspond with the second inner body <NUM>. That is, the first latch <NUM> may extend over a portion of the first inner body <NUM> and the second latch <NUM> may extend over a portion of the second inner body <NUM>.

The latch <NUM> (hereinafter referring to the first and second latches <NUM> and <NUM> collectively as the latch <NUM>) may be arranged to releasably lock the connector <NUM> with a complementary connector device. For example, the connector <NUM> may be used with an optical fiber port including mating components (not illustrated) configured to receive and secure the connector <NUM> through one or more locking formations <NUM> disposed on the latch <NUM>. In the illustrated embodiment, the locking formation(s) <NUM> include ramped surfaces located adjacent to a leading end <NUM> of the latch <NUM>. As described in greater detail herein, the leading end <NUM> of the latch <NUM> can be spaced apart from the housing <NUM>, permitting the locking formation(s) <NUM> to move relatively closer and farther away from the housing <NUM> to lock and unlock the connector <NUM> with respect to the optical fiber port.

The latch <NUM> may be engaged with the housing <NUM> at a trailing end <NUM> of the latch <NUM>. In an embodiment, the latch <NUM> may be integral with the housing <NUM>. That is, the latch <NUM> may be integrally part of the housing <NUM>. In another embodiment, the latch <NUM> may include one or more discrete components configured to engage with the housing <NUM>.

The leading end <NUM> of the latch <NUM> can be spaced apart from the trailing end <NUM> of the latch <NUM> by a middle portion <NUM> of the latch <NUM>. In an embodiment, the middle portion <NUM> can include a middle portion of the latch <NUM> (as viewed from a side view) between <NUM>% and <NUM>% of the length of the latch <NUM>, such as between <NUM>% and <NUM>% of the length of the latch <NUM>. The connector <NUM> in the illustrated not part of the claimed invention has a relatively straight middle portion <NUM>, as viewed from a side view (<FIG>), when the latch <NUM> is in an unbiased state. That is, the middle portion <NUM> of the latch <NUM> may be generally planar prior to application of force along the handle <NUM>, as described in greater detail herein.

The latch <NUM> can generally extend from the housing <NUM> in a direction toward the leading edge <NUM> of the connector <NUM>. For example, the trailing end <NUM> of the latch <NUM> may extend from the housing <NUM> and at least part of the middle portion <NUM> can be oriented in a direction generally toward the leading edge <NUM> of the connector <NUM>. Thus, the leading end <NUM> of the latch <NUM> may be disposed at a position closer to the leading edge <NUM> of the connector <NUM> than the trailing end <NUM> of the latch <NUM>. In an embodiment, the latch <NUM> can be cantilevered.

In one or more embodiments not part of the claimed invention, the latch <NUM> can further include a handle engagement member <NUM> forming an interface configured to engage with the handle <NUM>. In an embodiment, the handle engagement member <NUM> may form a releasable interface with the handle <NUM>. In such a manner, the handle <NUM> can be selectively removable from the latch <NUM>. In certain instances, the discrete handle <NUM> may permit easier formation of the connector <NUM> by allowing more complex connector geometry otherwise not possible in certain formation processes, e.g., molding. In the illustrated embodiment, the handle engagement member <NUM> includes a retention member <NUM>, e.g., a lip, configured to maintain engagement between the handle <NUM> and the handle engagement member <NUM>. In another embodiment, the handle <NUM> can be integrally formed with the housing <NUM>, such as at the latch <NUM>.

The handle <NUM> may extend between a latch engagement end <NUM> and a pull end <NUM>. The latch engagement end <NUM> can include one or more openings <NUM> configured to align with the latch <NUM> and other components of the housing <NUM> to permit locking and unlocking operations as described in greater detail herein. The handle <NUM> may have a variable profile, e.g., taper, between the latch engagement end <NUM> and the pull end <NUM>. In an embodiment not part of the claimed invention, the handle <NUM> can define a taper profile, as viewed from a top view (e.g., <FIG>), similar to the taper profile of the connector <NUM>.

In an embodiment not part of the claimed invention, one or more indicia can be included on the handle <NUM> to indicate, for example, which direction to pull the handle <NUM> to unlock the connector <NUM> from the optical fiber port.

<FIG> illustrate an embodiment not part of the claimed invention of a connector <NUM>. The connector <NUM> can have any number of similar or different features as compared to the connector <NUM> previously described with respect to <FIG>. For example, the connector <NUM> may include a housing <NUM>, a boot <NUM>, and a handle <NUM>. The connector <NUM> may engage with an optical fiber <NUM>.

In one or more embodiments, the housing <NUM> can include a plurality of pieces configured to engage with one another to form the housing <NUM>. For instance, the housing <NUM> can include two or more pieces that snap fit together in a releasable manner via snap fit connectors. The housing <NUM> can include a trailing end aperture (not illustrated) and first and second leading end apertures <NUM>. A section of optical fiber cable can be disposed within the housing <NUM> and extend at least partially between the trailing end aperture and the first and second leading end apertures <NUM>. The optical fiber <NUM> can be inserted into the housing <NUM> through the trailing end aperture. The boot <NUM> can overly a portion of the optical fiber <NUM> and a trailing portion <NUM> of the housing <NUM>.

The optical fiber <NUM> can furcate inside the housing <NUM> into first and second optical fibers (not illustrated). The first optical fiber can exit the housing <NUM> via the first leading end aperture <NUM> and the second optical fiber can exit the housing <NUM> via the second leading end aperture <NUM>. The first optical fiber may correspond with a receiving fiber (A) and the second optical fiber may correspond with a transmitting fiber (B).

The first optical fiber may be threaded into a bore <NUM> formed in a first inner body <NUM> and the end of the first optical fiber can be connected to a first ferrule <NUM>. The first inner body <NUM> may protrude from the housing <NUM> via the first leading end aperture <NUM>. The first inner body <NUM> may be fixed with respect to the housing <NUM>. The first inner body <NUM> can include engagement portions (not illustrated) to secure the first inner body <NUM> to the housing <NUM>. The engagement portions may prevent extrusion of the first inner body <NUM> from the housing <NUM> and/or prevent rotation between the first inner body <NUM> and the housing <NUM>. Moreover, the engagement portions may maintain the first inner body <NUM> at a fixed relative position with respect to the housing <NUM>.

The first ferrule <NUM> may protrude out of the bore <NUM> formed in the first inner body <NUM>. The first ferrule <NUM> and/or first inner body <NUM> may generally define a leading edge <NUM> of the connector <NUM>. The leading edge <NUM> may be insertable into an optical fiber port (<FIG>), e.g., part of an optical fiber panel, to permit optical connection between the optical fiber <NUM> and another optical fiber (not illustrated).

The second optical fiber may be threaded into a bore <NUM> formed in a second inner body <NUM>. The end of the second optical fiber can be connected to a second ferrule <NUM> which protrudes from the bore <NUM>. The second inner body <NUM> may be fixed with respect to the housing <NUM>. The second inner body <NUM> can include engagement portions (not illustrated), similar to or different from the engagement portions previously described with respect to the first inner body <NUM>, to secure the second inner body <NUM> to the housing <NUM>. The engagement portions may prevent extrusion of the second inner body <NUM> from the housing <NUM> and/or prevent rotation between the second inner body <NUM> and the housing <NUM>. Moreover, the engagement portions may maintain the second inner body <NUM> at a fixed relative position with respect to the housing <NUM>.

In certain instances, the housing <NUM> may include the first and second inner bodies <NUM> and <NUM>. That is, for example, the first and second inner bodies <NUM> and <NUM> may be integral with the housing <NUM>. Alternatively, the first and second bodies <NUM> and <NUM> can include discrete components configured to engage with the housing <NUM>. For example, the first and second bodies <NUM> and <NUM> may be engageable with the housing <NUM> upon snap fitting two or more pieces of the housing <NUM> to one another.

Like the connector <NUM> illustrated in <FIG>, the connector <NUM> may further include a latch <NUM> extending from the housing <NUM>. In an embodiment, the latch <NUM> can include a first latch <NUM> and a second latch <NUM>. The first latch <NUM> can correspond with the first inner body <NUM> and the second latch <NUM> can correspond with the second inner body <NUM>. That is, the first latch <NUM> may extend over a portion of the first inner body <NUM> and the second latch <NUM> may extend over a portion of the second inner body <NUM>.

The latch <NUM> (hereinafter referring to the first and second latches <NUM> and <NUM> collectively as the latch <NUM>) may be arranged to releasably lock the connector <NUM> with a complementary connector device. For example, the connector <NUM> may be used with an optical fiber port including mating components (not illustrated) configured to receive locking formation <NUM> disposed on the latch <NUM>. In the illustrated embodiment, the locking formation <NUM> includes a ramped surface located adjacent to a leading end <NUM> of the latch <NUM>. The leading end <NUM> of the latch <NUM> can be spaced apart from the housing <NUM>, thereby permitting the locking formation <NUM> to move relatively closer and farther away from the housing <NUM> to lock and unlock with the optical fiber port.

The latch <NUM> may be engaged with the housing <NUM> at a trailing end <NUM> of the latch <NUM>. In an embodiment, the latch <NUM> may be integral with the housing <NUM> or a component associated therewith. That is, the latch <NUM> may be part of the housing <NUM>. In another embodiment, the latch <NUM> may include one or more discrete components configured to engage with the housing <NUM>.

The leading end <NUM> of the latch <NUM> can be spaced apart from the trailing end <NUM> of the latch <NUM> by a middle portion <NUM> of the latch <NUM>. The latch <NUM> can generally extend from the housing <NUM> in a direction toward the leading edge <NUM> of the connector <NUM>. That is, for example, the trailing end <NUM> of the latch <NUM> may extend from the housing <NUM> with the middle portion <NUM> oriented in a direction generally toward the leading edge <NUM> of the connector <NUM>. In such a manner, the leading end <NUM> of the latch <NUM> can be closer to the leading edge <NUM> of the connector <NUM> than the trailing end <NUM> of the latch <NUM>.

In one or more embodiments not part of the claimed invention, the latch <NUM> may further include a handle engagement member <NUM> forming an interface with the handle <NUM>. In an embodiment, the handle engagement member <NUM> may form a releasable interface with the handle <NUM>. In such a manner, the handle <NUM> can be selectively removed from the latch <NUM>. In an embodiment, use of a discrete handle <NUM> may permit easier formation of the connector <NUM> by allowing use of more complex geometry during formation, e.g., molding, processes. In the illustrated embodiment, the handle engagement member <NUM> includes a retention member <NUM>, e.g., a lip, configured to maintain engagement between the handle <NUM> and the latch <NUM>.

The handle <NUM> may include a latch engagement end <NUM> and a pull end <NUM>. The latch engagement end <NUM> can include one or more openings <NUM> configured to align with the latch <NUM> and other components of the housing <NUM> so as to permit locking and unlocking operations as described in greater detail herein. The pull end <NUM> of the handle <NUM> can include a gripping area <NUM> configured for easier user grasp when pulling on the handle <NUM>.

The latch <NUM> in <FIG> is illustrated in an unbiased state as seen without application of external force applied to the latch <NUM>. Such configuration may be present when the connector <NUM> is uncoupled from other components, e.g., optical fiber ports. In one or more embodiments herein, the terms "biased" and "unbiased" may be used to refer to relative positions of the latch <NUM> or <NUM> when force is applied thereon, e.g., through the handle <NUM> or <NUM>. When force is applied on the handle <NUM> or <NUM>, the latch <NUM> or <NUM> may be considered in a biased state. Upon termination of force along the handle <NUM> or <NUM>, the latch <NUM> or <NUM> may return to an unbiased state. In a particular embodiment, the latch <NUM> or <NUM> may further define a third state, e.g., a locked state, where the latch <NUM> or <NUM> is coupled with components, e.g., optical fiber ports. The third state may be between the biased and unbiased states. That is, for example, the component, e.g., the optical fiber port, may provide slight biasing pressure against the latch <NUM> or <NUM> preventing full rebound from the biased state to the unbiased state even upon termination of force along the handle <NUM> or <NUM>. In the unbiased state, the latch <NUM> or <NUM> may be in a locked position relative to the component, e.g., the optical fiber port. In the biased state, the latch <NUM> or <NUM> may be in an unlocked position relative to the component, i.e., the latch <NUM> or <NUM> may be removable from the component.

In one or more embodiments, at least a portion of the latch <NUM> can lie along a curved line <NUM>, as viewed from a side view, when the latch <NUM> is in the unbiased state. For instance, in one or more embodiments at least part of the middle portion <NUM> of the latch <NUM> can lie along the curved line <NUM>. In an embodiment, at least <NUM>% of a length of the latch <NUM> lies along the curved line <NUM> when the latch <NUM> is unbiased, such as wherein at least <NUM>% of the length of the latch <NUM> lies along the curved line <NUM> when the latch <NUM> is unbiased, such as wherein at least <NUM>% of the length of the latch <NUM> lies along the curved line <NUM> when the latch <NUM> is unbiased, such as wherein at least <NUM>% of the length of the latch <NUM> lies along the curved line <NUM> when the latch <NUM> is unbiased, such as wherein at least <NUM>% of the length of the latch <NUM> lies along the curved line <NUM> when the latch <NUM> is unbiased, such as wherein at least <NUM>% of the length of the latch <NUM> lies along the curved line <NUM> when the latch <NUM> is unbiased, such as wherein at least <NUM>% of the length of the latch <NUM> lies along the curved line <NUM> when the latch <NUM> is unbiased, such as wherein at least <NUM>% of the length of the latch <NUM> lies along the curved line <NUM> when the latch <NUM> is unbiased, such as wherein at least <NUM>% of the length of the latch <NUM> lies along the curved line <NUM> when the latch <NUM> is unbiased, such as wherein at least <NUM>% of the length of the latch <NUM> lies along the curved line <NUM> when the latch <NUM> is unbiased. In an embodiment, the curved line <NUM> can represent a best-fit curved line associated with a curvature of the latch <NUM> or a portion thereof.

In one or more embodiments, the curved line <NUM> can define a radius of curvature, Ri (<FIG>), as measured when the latch <NUM> is in an unbiased state. By way of example, Ri may be less than <NUM> inches (in), such as less than <NUM> in, such as less than <NUM> in, such as less than <NUM> in, such as less than <NUM> in, such as less than <NUM> in, such as less than <NUM> in, such as less than <NUM> in, or such as less than <NUM> in. The length or the unbiased radius of curvature, R<NUM>, of the latch <NUM> may affect the force required to unlock the latch <NUM> from an optical fiber port, as described in greater detail herein.

In one or more embodiments, the latch <NUM> may conform to the curved line <NUM> along the entire trailing end <NUM> and at least part of the middle portion <NUM> of the latch <NUM>. That is, the latch <NUM> may define a continuously curved profile, as measured from the housing <NUM> through at least part of the middle portion <NUM>. In an embodiment, the locking formation <NUM> can lie along a portion of the latch <NUM> that does not lie along the curved line <NUM> to permit use of the latch <NUM> with existing optical fiber ports having predefined engagement structure shapes and designs.

<FIG> illustrates a side view of the connector <NUM> with an arrow <NUM> indicating a pull direction for the handle <NUM> when unlocking the connector <NUM> from an optical fiber port, and an arrow <NUM> indicating a responsive deformation direction of the leading end <NUM> of the latch <NUM> in response to pulling the handle <NUM>. To decouple the connector <NUM> from the optical fiber port, an operator can pull on the handle <NUM> in the direction indicated by arrow <NUM>. Deflection of the latch <NUM>, e.g., the middle portion <NUM> and trailing end <NUM>, can cause downward deflection of the leading end <NUM>, permitting the locking formation <NUM> to clear a mating component (not illustrated) of the optical fiber port. Downward deflection, as used with respect to <FIG> is intended to refer to deflection in a direction toward the housing <NUM>.

Curvature of the latch <NUM> may reduce the force required in the direction indicated by arrow <NUM> to move the latch <NUM> from the locked position to the unlocked position. For instance, the force required to unlock the latch <NUM> illustrated in <FIG> may be approximately <NUM> Newtons (N) whereas a similar latch having a curved profile (e.g., <FIG>) may unlock upon application of a force of approximately <NUM> N.

<FIG> illustrates the connector <NUM> in a locked position, e.g., when engaged with mating components of an optical fiber port. It should be understood that the locked position may correlate with an unbiased state of the latch <NUM>. Alternatively, the locked position may include slight deflection of the latch <NUM> provided by the mating component of the optical fiber port but less biasing, e.g., along arrow <NUM> (<FIG>), than in a biased state, e.g., when the latch <NUM> is biased to install or remove the connector <NUM> from the optical fiber port. <FIG> illustrates the connector <NUM> in an unlocked position, i.e., permitting an operator to remove the connector <NUM> from the optical fiber port.

In the locked position (<FIG>), the latch <NUM> defines a first aspect ratio, as measured by an effective length, LE1, of the latch <NUM> relative to an effective height, HE1, of the latch <NUM>. In the unlocked position (<FIG>), the latch <NUM> defines a second aspect ratio, as measured by the effective length, LE2, of the latch <NUM> relative to the effective height, HE2, of the latch <NUM>. The first aspect ratio may be defined by Equation (<NUM>).

The second aspect ratio may be defined by Equation (<NUM>).

Effective lengths of the latch <NUM>, LE1 and LE2, may be measured by the distance between opposite ends of the latch <NUM>, e.g., between the leading end <NUM> and trailing end <NUM> of the latch <NUM>. Effective heights of the latch <NUM>, HE1 and HE2, may be measured by the distance between a nearest major surface <NUM> of the housing <NUM>, or a best fit plane relative thereto, and a farthest point <NUM> of the latch <NUM>, as measured perpendicular to the major surface <NUM> of the housing <NUM>.

As the handle <NUM> is pulled in the direction indicated by arrow <NUM> in <FIG>, the effective length of the latch <NUM> may decrease while the effective height of the latch <NUM> may increase. In this regard, the aspect ratio of the latch <NUM> may decrease as the latch <NUM> is moved from the locked position to the unlocked position.

Moreover, a radius of curvature of the latch <NUM> may change during transition between the locked position and the unlocked position. For example, the latch <NUM>, or a portion thereof, may define a first radius of curvature, R<NUM>, as measured in the locked position (<FIG>), and a second radius of curvature, R<NUM>, as measured in the unlocked position (<FIG>). In an embodiment, Ri can be greater than R<NUM>. For instance, R<NUM> may be at least <NUM> R<NUM>, such as at least <NUM> R<NUM>, such as at least <NUM> R<NUM>, such as at least <NUM> R<NUM>, such as at least <NUM> R<NUM>, such as at least <NUM> R<NUM>, or such as at least <NUM> R<NUM>. In another embodiment, Ri may be no greater than <NUM> R<NUM>, such as no greater than <NUM> R<NUM>, or no greater than <NUM> R<NUM>.

As the latch <NUM> deforms between the locked and unlocked positions, a distance between the locking formation <NUM> and the housing <NUM> may change. For instance, in a locked position the locking formation <NUM> can define a locked distance, DL, as measured by a distance of the locking formation <NUM> from the nearest major surface <NUM> of the housing <NUM> when the latch <NUM> is in the locked position, greater than an unlocked distance, Du, as measured by a distance of the locking formation <NUM> from the nearest major surface <NUM> of the housing <NUM> when the latch <NUM> is in the unlocked position. The locked and unlocked distances, DL and Du, can be configured such that the connector <NUM> may be selectively secured and decoupled from the optical fiber port.

<FIG> illustrates a top view of a handle <NUM> of a connector. The handle <NUM> can include features similar to the handles <NUM> or <NUM> previously described. In an embodiment, the handle <NUM> has a latch engagement end <NUM> and a pull end <NUM> with a gripping area <NUM> configured to facilitate easier gripping of the handle <NUM>.

The handle <NUM> may include one or more openings <NUM> configured to align with the latch, e.g., latch <NUM> or latch <NUM>, and other components of the housing, e.g., housing <NUM> or <NUM>. The openings <NUM> can include one or more engagement openings <NUM>, configured to engage with the handle engagement member, e.g., handle engagement member <NUM> or <NUM>, and one or more latch opening <NUM> configured to receive the latch, e.g., latch <NUM> or <NUM>, therethrough. A tab <NUM> may extend into the latch opening <NUM>. The tab <NUM> may be configured to extend into a gap between the first and second latches <NUM> and <NUM> or <NUM> and <NUM>. For example, referring to <FIG>, the tab <NUM> may extend into the gap <NUM> between the first and second latches <NUM> and <NUM> or <NUM> and <NUM>. The tab <NUM> may prevent torsional misalignment of the handle <NUM> in a lateral direction, e.g., along line <NUM>, and maintain the handle <NUM> properly seated with respect to the rest of the connector.

<FIG> illustrates a connector <NUM> in accordance with one or more embodiments described herein, and not part of the claimed invention, coupled with an optical fiber port <NUM>. <FIG> illustrates the connector <NUM> with force applied to the connector through the handle <NUM> to bias the locking feature, e.g., the latch <NUM>, to an unlocked position, permitting removal of the connector <NUM> from the optical fiber port <NUM>. More specifically, applying force through the handle <NUM> can deflect the latch <NUM> to clear mating components <NUM> within the optical fiber port <NUM>. In an embodiment, a portion of the handle <NUM> can extend into the optical fiber port <NUM>. The latch <NUM> of the connector <NUM> can engage with mating components <NUM> of the optical fiber port <NUM> and selectively secure the connector <NUM> to the optical fiber port <NUM>. As the handle <NUM> is pulled in a direction away from the optical fiber port <NUM>, the latch <NUM> can deflect downward, e.g., toward a housing <NUM> of the connector <NUM>, releasing the latch <NUM> from the mating components <NUM> of the optical fiber port <NUM> and permitting removal of the connector <NUM> from the optical fiber port <NUM>.

It is noted that the profile change of the curvature of the latch <NUM> illustrated in <FIG> and <FIG> is exemplary only. In certain instances, the latch <NUM> can deform primarily at one end thereof, along the middle portion, or a combination thereof. Among other things, the resulting profile change of the latch <NUM> may be associated with the location of the handle engagement member <NUM> or <NUM>, the design of the handle engagement member <NUM> or <NUM>, the shape of the latch <NUM>, the design of the handle <NUM>, or any combination thereof. Certain profile designs may be particularly suitable for different optical fiber ports <NUM> and can be selected accordingly.

<FIG> illustrates an exemplary method <NUM> of decoupling a connector from an optical fiber port. The method <NUM> can include a step <NUM> of moving a handle of the connector in a direction away from the optical fiber port. The handle can be coupled to a latch of the connector. The latch can be coupled to a housing of the connector and can extend toward a leading edge of the connector. In an embodiment not part of the claimed invention, moving the handle can cause an aspect ratio of the latch, as previously described herein, to decrease. In another embodiment not part of the claimed invention, moving the handle away from the optical fiber port can cause a radius of curvature of the latch to decrease. In a further embodiment not part of the claimed invention, moving the handle can cause the middle portion of the latch to move in a direction away from the housing (e.g., <FIG>). The method <NUM> can further include a step <NUM> of removing the connector from the optical fiber port. In an embodiment not part of the claimed invention, the method <NUM> can also include reattaching the connector to the optical fiber port by inserting the connector into the optical fiber port until a locking formation of the connector engages with a mating component of the optical fiber port. The latch may automatically move to a locked position upon engagement of the locking formation with the mating component.

According to the claimed invention, the connector is biased from a locked configuration to an unlocked configuration by applying a biasing force along the boot of the connector. For example, <FIG> illustrates an embodiment of a connector <NUM> in accordance with an embodiment of the claimed invention and described herein. The connector <NUM> can have any one or more similar features and/or attributes as compared with the connector <NUM> previously described herein. The connector <NUM> includes a housing <NUM>, a boot <NUM>, and can include an intermediary element <NUM>. The housing <NUM> can include any one or more similar features as previously described with respect to housing <NUM>. For instance, the housing <NUM> can include a latch <NUM> extending from a body of the housing <NUM>. In an embodiment, the latch <NUM> can include first and second portions <NUM> and <NUM>. The first and second portions <NUM> and <NUM> can define spaces for ferrules and/or portions of optical fiber disposed within the housing <NUM>.

The latch <NUM> may be arranged to releasably lock the connector <NUM> with a complementary connector device. For example, the connector <NUM> may be used with an optical fiber port including mating components (not illustrated) configured to receive and secure the connector <NUM> through one or more locking formations <NUM> disposed on the latch <NUM>. In the illustrated embodiment, the locking formation(s) <NUM> include ramped surfaces located adjacent to a leading end <NUM> of the latch <NUM>. As described in greater detail herein, the leading end <NUM> of the latch <NUM> can be spaced apart from the housing <NUM>, permitting the locking formation(s) <NUM> to move relatively closer and farther away from the housing <NUM> to lock and unlock the connector <NUM> with respect to the optical fiber port. When the leading end <NUM> is disposed relatively closer to the housing <NUM> it may be in an unlocked configuration. Conversely, when the leading end <NUM> is relative farther spaced apart from the housing <NUM>, the connector <NUM> may be in a locked configuration.

The latch <NUM> may be engaged with the housing <NUM> at a trailing end <NUM> of the latch <NUM>. In an embodiment, the latch <NUM> may be integral with the housing <NUM>. That is, the latch <NUM> may be integrally part of the housing <NUM>. In another embodiment, the latch <NUM> may include one or more discrete components configured to be engaged with the housing <NUM>.

The leading end <NUM> of the latch <NUM> can be spaced apart from the trailing end <NUM> of the latch <NUM> by a middle portion <NUM> of the latch <NUM>. In an embodiment, the middle portion <NUM> can include a middle portion of the latch <NUM> (as viewed from a side view) between <NUM>% and <NUM>% of the length of the latch <NUM>, such as between <NUM>% and <NUM>% of the length of the latch <NUM>.

The latch <NUM> can generally extend from the housing <NUM> in a direction toward the leading end <NUM> of the connector <NUM>. For example, the trailing end <NUM> of the latch <NUM> may extend from the housing <NUM> and at least part of the middle portion <NUM> can be oriented in a direction generally toward the leading edge <NUM> of the connector <NUM>. Thus, the leading end <NUM> of the latch <NUM> may be disposed at a position closer to the leading edge <NUM> of the connector <NUM> than the trailing end <NUM> of the latch <NUM>. In an embodiment, the latch <NUM> can be cantilevered.

In one or more embodiments, the latch <NUM> can further include an intermediary engagement member <NUM> forming an interface configured to engage with the intermediary element <NUM>. In an embodiment, the intermediary engagement member <NUM> may form a releasable interface with the intermediary element <NUM>. In such a manner, the intermediary element <NUM> can be selectively removable from the latch <NUM>. In certain instances, the discrete intermediary element <NUM> may permit easier formation of the connector <NUM> by allowing more complex connector geometry otherwise not possible in certain formation processes, e.g., molding. In the illustrated embodiment, the intermediary engagement member <NUM> includes a retention member, e.g., a lip, configured to maintain engagement between the intermediary element <NUM> and the intermediary engagement member <NUM>. In another embodiment, the intermediary element <NUM> can be integrally formed with the housing <NUM>.

Referring to <FIG>, the boot <NUM> can include a flexible portion <NUM> configured to permit flexure of an optical fiber disposed therein. The boot <NUM> can further include a complementary engagement feature <NUM> configured to engage with an engagement feature <NUM> (<FIG>) of the intermediary element <NUM>. By way of example, the complementary engagement feature <NUM> can include a projection or recess. The complementary engagement feature <NUM> can further include a hook, handle, clip, snap, ridge, channel, knurling, or any other structural features to assist in engagement with the engagement feature <NUM> of the intermediary element <NUM>. In the illustrated embodiment, the complementary engagement feature <NUM> is disposed adjacent to a leading edge <NUM> of the boot <NUM>. In another embodiment, the complementary engagement feature <NUM> can be spaced apart from the leading edge <NUM> of the boot <NUM>. The complementary engagement feature <NUM> can extend toward the flexible portion <NUM>, e.g., an entire distance between the leading edge <NUM> and the flexible portion <NUM>. In another embodiment, the complementary engagement feature <NUM> can be spaced apart from the flexible portion <NUM> of the boot <NUM>.

The intermediary element <NUM> illustrated in <FIG> can include an engagement feature <NUM> having a shape and/or size configured to engage with the complementary engagement feature <NUM> of the boot <NUM>. For example, the engagement feature <NUM> can include an opening extending through the intermediary element <NUM> and configured to receive at least a portion of the complementary engagement feature <NUM>. In certain instances, the complementary engagement feature <NUM> of the boot can move relative to the engagement feature <NUM> of the intermediary element <NUM>. For example, the engagement feature <NUM> can define a length greater than a length of the complementary engagement feature <NUM>. In such a manner, the intermediary element <NUM> can move without creating biasing pressure against the complementary engagement feature <NUM> of the boot <NUM>.

In an embodiment, the engagement feature <NUM> and complementary engagement feature <NUM> can be interlocked by interference with one or more features, including for example, one or more of channels, grooves, ridges, projections, castellations, or other known interference features. In the illustrated embodiment of <FIG>, the complementary engagement feature <NUM> includes laterally extending guides which are dimensioned to maintain the complementary engagement feature <NUM> within the engagement feature <NUM>, e.g., opening, of the intermediary element <NUM>. Use of interference, or another similar type of selectively engageable interface, between the engagement feature <NUM> and complementary engagement feature <NUM> can allow an operator to assemble the boot <NUM> relative to the housing <NUM> more easily while still ensuring that the intermediary element <NUM> and boot <NUM> remain coupled together during operational use of the connector <NUM>.

The intermediary element <NUM> can have a coupling portion <NUM> configured to engage with the intermediary engagement member <NUM> of the latch <NUM>. Referring to <FIG>, the coupling portion <NUM> can include a linear portion, such as a bar, extending transverse to a length of the intermediary element <NUM>. The bar can engage with the housing at two or more locations along the latch <NUM>. Referring to <FIG>, the coupling portion <NUM> can include a reinforced curved portion extending transverse to a length of the intermediary element <NUM>. The reinforced curved portion can exhibit reduced flexure when the intermediary element <NUM> is biased, e.g., from biasing force applied to the boot <NUM>, thus decreasing the biasing force necessary to unlock the connector <NUM> from an optical fiber port.

<FIG> illustrate a connector <NUM> in accordance with another embodiment according to the claimed invention. The connector <NUM> can include one or more of the features of connector <NUM> and/or connector <NUM>, such as a housing <NUM>, a boot <NUM>, and an intermediary element <NUM>. In the illustrated embodiment, the intermediary element <NUM> includes an engagement feature <NUM> having raised leading and trailing portions <NUM> and <NUM>. The raised trailing portion <NUM> may provide additional support with a complementary engagement portion <NUM> of the boot <NUM> to prevent detachment of the intermediary element <NUM> from the boot <NUM>, in particular during locking and unlocking of the connector <NUM> from an optical fiber port as described hereinafter. In an embodiment, the intermediary element <NUM> can further include raised lateral sides <NUM> and <NUM>. In the illustrated embodiment, the lateral sides <NUM> and <NUM> define guides <NUM> configured to maintain the connection between the intermediary element <NUM> and the complementary engagement portion <NUM> of the boot <NUM>.

The intermediary element <NUM> can include reinforced portions, e.g., areas with increased thickness or dimensions, to reduce material flexure and decrease the biasing force necessary to unlock the connector <NUM> from an optical fiber port.

<FIG> illustrate a connector <NUM> in accordance with another embodiment according to the claimed invention. The connector <NUM> can include one or more of the features of connector <NUM>, connector <NUM> and/or connector <NUM>. In an embodiment, the connector <NUM> includes a housing <NUM>, a boot <NUM>, and an intermediary element <NUM>.

The intermediary element <NUM> can include an engagement feature <NUM> configured to engage with a complementary engagement feature <NUM> of the boot <NUM>. In the illustrated embodiment, the complementary engagement feature <NUM> is disposed entirely on the boot <NUM>. In another embodiment, at least a portion of the complementary engagement feature <NUM> can be disposed on the housing <NUM>. In the illustrated embodiment, the engagement feature <NUM> includes a channel <NUM> configured to be engaged with a projection <NUM> of the complementary engagement feature <NUM>. In another embodiment, the engagement feature <NUM> can include a projection and the complementary engagement feature <NUM> can include a channel. In yet further embodiments, the intermediary element <NUM> and boot <NUM> can include one or more other shaped features configured to be engaged together, e.g., clasps, lips, dimples, ridges, undulating or castellated surfaces, or other elements configured to be engaged together.

In an embodiment, the engagement feature <NUM> can further include a secondary interface <NUM> configured to be engaged with a secondary interface <NUM> of the boot <NUM>. By way of example, the secondary interfaces <NUM> and <NUM> can include fingers configured to extend into, e.g., clip with respect to, recesses. For example, in the illustrated embodiment, the secondary interface <NUM> of the intermediary element <NUM> comprises fingers and the secondary interface <NUM> of the boot <NUM> comprises recesses configured to engage with the fingers of the intermediary element <NUM>. The secondary interfaces <NUM> and <NUM>, when coupled together, can act to create a semi-permanent coupling interface between the boot <NUM> and the intermediary element <NUM>, preventing undesired detachment therebetween.

In an embodiment, the secondary interface <NUM> of the boot <NUM> can be reversible with respect to the secondary interface <NUM> of the housing <NUM>. That is, for example, the secondary interface <NUM> can be engageable with the secondary interface <NUM> when the boot <NUM> is oriented at multiple rotational orientations with respect to the housing <NUM>. By way of example, the secondary interface <NUM> can include one or more centered recesses such that the same fingers can be utilized at the same positions in either rotational orientation of the boot <NUM>. Alternatively, the secondary interface <NUM> can include at least two recesses - a first recess configured to engage the fingers of the secondary interface <NUM> in a first rotational orientation and a second recess configured to engage the fingers of the secondary interface <NUM> in a second rotational orientation (e.g., <NUM>° opposite the first rotational orientation). In an embodiment, the recess(es) can include a plurality of recesses, such as a plurality of recesses. The number of recesses can correspond with the number of fingers to be engaged therewith.

In an embodiment, the secondary interfaces <NUM> and <NUM> can function as attachment protocol to prevent unwanted detachment between the boot <NUM> and intermediary element <NUM> during operation of the connector <NUM>. That is, the secondary interfaces <NUM> and <NUM> can maintain operational communication between the channel <NUM> of the intermediary element <NUM> and the projection <NUM> of the boot <NUM> (or vise versa), preventing undesired detachment therebetween.

In one or more embodiments, the boot <NUM> can be integrally formed with the intermediary element <NUM>. In an embodiment, the boot <NUM> and intermediary element <NUM> portions of the integral boot/intermediary element assembly can be formed from different materials. For example, the boot portion of the integral assembly can be formed from a relatively flexible material and the intermediary element portion of the integral assembly can be formed from a relatively less flexible material. The integral assembly may be formed, for example, through overmolding or another multi-material capable process(es).

<FIG> shows the connector <NUM> in a locked configuration, where a latch <NUM> of the housing <NUM> is configured to engage with mating components on an optical fiber port. <FIG> shows the connector <NUM> in an unlocked configuration, where the latch <NUM> is disposed at a position such that the connector <NUM> can pass freely from the optical fiber port. A user can selectively transition the connector <NUM> from the locked configuration to the unlocked configuration by applying a biasing force to the boot <NUM> in a direction, such as the direction illustrated by arrow <NUM>, generally away from the housing <NUM>.

In an embodiment, the housing <NUM> and boot <NUM> can be configured to float relative to one another. As used herein, "float" refers to a connection type between the housing <NUM> and boot <NUM> whereby the two components are coupled together and can be moved relative to one another. For instance, the housing <NUM> and boot <NUM> can be tracked relative to one another so as to remain coupled together while permitting displacement therebetween along the tracked engagement interface. The housing <NUM> and boot <NUM> can float relative to one another in the locked configuration and in the unlocked configuration. In one or more embodiments, the housing <NUM> and boot <NUM> can be selectively fixed together to prevent relative float therebetween. For example, the connector <NUM> may include an engageable interconnect (not illustrated) between the housing <NUM> and boot <NUM> that allows an operator to selectively lock the two components together and prevent displacement of the boot <NUM> relative to the housing <NUM>. In such a manner, the operator can selectively prevent the housing <NUM> and boot <NUM> from floating relative to each other.

In the unlocked configuration, a gap <NUM> can form between a surface <NUM> of the housing <NUM> and a surface <NUM> of the boot <NUM>. In another embodiment, the gap <NUM> may be formed between adjacent portions of the boot <NUM> or adjacent portions of the housing <NUM>. That is, for example, the surfaces <NUM> and <NUM> can both be part of the boot <NUM> or both be part of the housing <NUM>. In a non-illustrated embodiment, for example, the boot <NUM> may include a first portion coupled with the housing <NUM> and a second portion that is axially displaceable with respect to the first portion. In such a manner, the operator can open the latch <NUM> by applying biasing force to the second portion of the boot <NUM>.

The gap <NUM> can increase in size as the boot <NUM> is biased away from the housing <NUM>. An interfacing portion <NUM> can remain disposed between the housing <NUM> and boot <NUM> when the connector <NUM> is in the unlocked configuration in order to prevent axial misalignment between the housing <NUM> and boot <NUM>. The interfacing portion <NUM> may be received, for example, in a recess of at least one of the housing <NUM> and boot <NUM> to restrict transverse movement between the housing <NUM> and the boot <NUM>. In an embodiment, the interfacing portion <NUM> can be part of the boot <NUM>. In another embodiment, the interfacing portion <NUM> can be part of the housing <NUM>. In yet another embodiment, the interfacing portion <NUM> can be at least partially formed by the housing <NUM> and the boot <NUM>. In another embodiment, the interfacing portion <NUM> can include a discrete component that floats relative to the housing <NUM>, the boot <NUM>, or both the housing <NUM> and boot <NUM>. In one or more embodiments, the interfacing portion <NUM> or another portion of the connector <NUM> can maintain the boot <NUM> within a predefined distance from the housing <NUM> upon application of biasing force along the boot <NUM>. Thus, for instance, the boot <NUM> and housing <NUM> can remain coupled together and cannot be separated upon application of a large force, e.g., an accidental shock force, applied on the boot <NUM> in the direction of arrow <NUM>.

The length, Li, of the connector <NUM> in the locked configuration (<FIG>) as measured between a leading edge <NUM> of the connector <NUM> and a trailing edge <NUM> of the connector <NUM>, can be different than the length, L<NUM>, of the connector <NUM> in the unlocked configuration (<FIG>) as measured between the leading edge <NUM> and the trailing edge <NUM>. In an embodiment, L<NUM> is greater than Li. For example, L<NUM> can be at least <NUM> Li, such as at least <NUM> Li, such as at least <NUM> Li, such as at least <NUM> Li, such as at least <NUM> Li, such as at least <NUM> Li, such as at least <NUM> Li. In one or more embodiments, the change in length between L<NUM> and L<NUM> can be accommodated by a corresponding increase in size of the gap <NUM> between the housing <NUM> and the boot <NUM>. While nominal material elasticity may cause slight connector elongation during application of biasing forces along the boot <NUM> in certain instances almost all of the length change associated with application of a biasing force along the boot <NUM> can correspond with an increased gap <NUM> size. For example, at least <NUM>% of the change in length of the connector <NUM> can correspond with a change in size of the gap <NUM>, such as at least <NUM>% of the change in length of the connector <NUM> can correspond with a change in size of the gap <NUM>, such as at least <NUM>% of the change in length of the connector <NUM> can correspond with a change in size of the gap <NUM>, such as at least <NUM>% of the change in length of the connector <NUM> can correspond with a change in size of the gap <NUM>, such as at least <NUM>% of the change in length of the connector <NUM> can correspond with a change in size of the gap <NUM>. In a more particular embodiment, the length change of the connector <NUM> when moving between locked and unlocked configurations can correspond entirely with the size change of the gap <NUM>.

In an embodiment, the length of the connector <NUM> can increase by at least <NUM> when moved from the locked to unlocked configuration, such as by at least <NUM> when moved from the locked to unlocked configuration, such as by at least <NUM> when moved from the locked to unlocked configuration, such as by at least <NUM> when moved from the locked to unlocked configuration, such as by at least <NUM> when moved from the locked to unlocked configuration, such as by at least <NUM> when moved from the locked to unlocked configuration, such as by at least <NUM> when moved from the locked to unlocked configuration, such as by at least <NUM> when moved from the locked to unlocked configuration.

The connector <NUM> may return to the locked configuration upon termination of application of the biasing force on the boot <NUM>. In one or more embodiments, the connector <NUM> can automatically return to the locked configuration upon termination of the application of the biasing force on the boot <NUM>. For example, in an embodiment, the biasing force transmitted through the boot <NUM> can be stored, e.g., in the latch <NUM>. When the biasing force is terminated, the stored energy can bias the boot <NUM> back to a location more proximate to the housing <NUM>, e.g., the locked configuration. In other embodiments, the connector <NUM> may require manual manipulation to switch the connector <NUM> to the locked configuration from the unlocked configuration. For instance, the connector <NUM> can include one or more clips, detents, snaps, or other similar features which selectively prevent return of the connector <NUM> to the locked configuration. In such embodiments, the operator can selectively manipulate the connector <NUM> to either release a stored energy or manually move the connector <NUM> back to the locked configuration.

Referring now to <FIG>, a connector <NUM> in accordance with an embodiment can include an integrated boot <NUM> generally including a boot <NUM> and a handle <NUM> configured to be secured together through an interface, such as interface <NUM>. The interface <NUM> can include complementary engagement features disposed on the boot <NUM> and handle <NUM>, such as for example, a projection <NUM> and an opening <NUM> configured to receive the projection <NUM>. In the illustrated embodiment, the projection <NUM> is shown as part of the handle <NUM> and the opening <NUM> as part of the boot <NUM>. In other embodiments, the projection <NUM> can be part of the boot <NUM> and the projection <NUM> can be part of the handle <NUM>. In yet further embodiments, the complementary engagement features can include other attachment protocol, including for example, bayonet connections, interference fits, clips, clamps, and the like.

As illustrated in <FIG>, in a particular embodiment the projection <NUM> can include a lip <NUM> configured to seat relative to a surface of the opening <NUM> so as to prevent the projection <NUM> from inadvertently pulling therefrom. The lip <NUM> can be disposed on a split projection <NUM>, including for example, two or more axially extending portions spaced apart at least partially by a gap. In such a manner, the split projection <NUM> can deform to permit the lip <NUM> to pass through the opening <NUM> during installation of the integrated boot <NUM>.

In an embodiment, installation of the boot <NUM> and handle <NUM> can be performed by translating the boot <NUM> and handle <NUM> together in a direction generally parallel with the interface <NUM>. In another embodiment, installation of the boot <NUM> and handle <NUM> can include rotation and/or pivoting of one or both of the boot <NUM> and handle <NUM> in combination with, or instead of, translation therebetween.

Referring to <FIG>, in an embodiment, the lip <NUM> can be replaced by a flange <NUM>. The flange <NUM> can extend in a direction generally perpendicular to the projection <NUM> and engage with the opening <NUM>. In the illustrated embodiment, the opening <NUM> has a generally polygonal shape, e.g., square shape. The opening <NUM> can be sized and/or shaped to correspond with the shape of the lip <NUM> or flange <NUM>. In an embodiment, the opening <NUM> can define a tight fit with the lip <NUM> or flange <NUM> so as to prevent undesired detachment therebetween during use.

Referring to <FIG>, the integrated boot <NUM> can appear as a single piece in the assembled state. When force is applied along the integrated boot <NUM> in a direction generally parallel with arrow A, the integrated boot <NUM> can create pressure on a latch <NUM> of the connector <NUM> to transition the connector <NUM> from a locked configuration to an unlocked configuration. Similarly, when application of force is terminated, the latch <NUM> can return to the locked configuration as previously described.

Connectors in accordance with one or more embodiments described herein may facilitate easier installation and removal of an optical fiber connector with respect to one or more optical fiber ports. Specifically, installation of the optical fiber connector can include translating the optical fiber connector into the optical fiber port until one or more latches of the connector engage with mating components of the port while removal can be performed by pulling on a handle of the optical fiber connector and pulling the optical fiber connector from the port. Use of a curved latch with locking formation(s) may reduce the force required to disengage the connector from the optical fiber port.
