Patent ID: 7454099

Claim:
An optical channel shifting device, comprising: a containing unit with a first inner space and a second inner space adjacent to the first inner space, comprising: a first side; a second side opposite to the first side; two guiding channels located between the first side and the second side and held in the first inner space; and a separating wall defining the first inner space and the second inner space and comprising an opening communicating with the first inner space and the second inner space; an input optical fiber, located in the first side of the containing unit along a first axis and held in the first inner space and extending from the first side to the second side along the first axis, including: a first terminal located in the first side; and a second terminal opposite to the first terminal; an output unit, comprising: a first output optical fiber, held in one of the guiding channels along the first axis and comprising a first terminal set in the second side and a second terminal adjacent to the second terminal of the input optical fiber; and a second output optical fiber, held in another of the guiding channels along a second axis parallel to the first axis and comprising a first terminal set in the second side and a second terminal adjacent to the second terminal of the input optical fiber; and a driving assembly, located in the second inner space of the containing unit, comprising: a switching lever shifted in either a first position or a second position; and a performing edge touching the switching lever and attached with the input optical fiber in the form of the point-contact; whereby the switching lever lowers the performing edge such that the input optical fiber is aligned with the first output optical fiber in the form of optical coupling when the switching lever is in the first position; the switching lever elevates the performing edge such that the input optical fiber is aligned with the second output optical fiber in the form of optical coupling when the switching lever is in the second position; and the performing edge of the switching lever is shifted in either the first position or the second position through the opening.
