Abstract:
1. A pluggable optical passive device comprising: an elongated enclosure provided to house one or two optical components; two first connectors respectively to receive two female plugs, wherein the two first connectors are disposed on one end of the elongated enclosure and fixed thereto by epoxy, and coupled to the one or two optical components on one end thereof; and two second connectors respectively to receive two male plugs, wherein the two second connectors are disposed on another end of the elongated enclosure and fixed thereto by epoxy, and coupled to the one or two optical components on another end thereof, the one or two components each include two optical filters therein, each of the filters is coupled between one of the two first connectors and one of the two second connectors, and wherein the pluggable optical passive device provides an add/drop function to add a component signal from an external source and drop a component signal to the external source, and the component signal from the external source and the component signal to the external source have a substantially similar wavelength at which the each of the optical filters is configured to pass through and reflect others.
