Patent ID: 7239812

Claim:
A pluggable bi-directional transceiver with a single optical fiber, comprising: a sub-assembly module of optical transceiver connected with an optical fiber for receiving and transmitting optical signals, said sub-assembly module comprising an optical fiber as a medium for transmitting optical signals, a laser-diode transmitter for converting electronic signals into optical signals and transmitting the optical signals outwardly, a signal receiver for receiving and converting optical signals into electronic signals, a wavelength division multiplexer (WDM) located among said laser-diode transmitter, said signal receiver, and said optical fiber for separating optical signals of different wavelengths, a supporting rack for supporting said WDM, a casing for fixing and protecting said laser-diode transmitter, said signal receiver, and said WDM, and an optical-fiber connector connected with said optical fiber; a printed circuit board (PCB) connected with said sub-assembly module, and also connected with a communication equipment under a pluggable condition for exchange of signals between said sub-assembly module and said communication equipment; a main frame located above said sub-assembly module and said PCB for fixing and protecting said sub-assembly module and said PCB; a tab for pulling said transceiver out of said communication equipment; a tab-base provided with an anchoring member for fixing said transceiver onto said communication equipment; a lower cover located under said sub-assembly module and said PCB for fixing and protecting said sub-assembly module and said PCB; and an upper cover located above said main frame; wherein said optical-fiber connector of said sub-assembly module further comprises a fiber-guiding tube, a ceramic sheath and a metallic sleeve, said fiber-guiding tube being located at a tail end of said optical fiber and connected with said optical fiber; said ceramic sheath enclosing said fiber-guiding tube, and said metallic sleeve enclosing said ceramic sheath.
