Bidirectional modular optoelectronic transceiver assembly

Claim 1

A transceiver assembly comprising: a transmitter module including a housing, a source of an outgoing optical signal mounted in a wall of said housing, an aperture in a wall of said housing, a socket including a cylindrical bore disposed within said aperture, and a lens for coupling said outgoing signal through said aperture, and a receiver-splitter module having a cavity and a transverse bore optically coupled thereto, a detector of an incoming optical signal mounted in said cavity, a first ferrule having a flat first endface and an opposite oblique endface, said first ferrule containing a fiber segment, the fiber segment having a first flat endface coplanar with said first ferrule flat first endface and having an oblique endface coplanar with said first ferrule oblique endface wherein the fiber segment oblique endface includes a coating adapted to partially transmit said outgoing signal and to partially reflect said incoming signal into said detector, the flat first endface of said first ferrule being insertable into said socket cylindrical bore so that said fiber segment receives said outgoing signal, and a second ferrule having an oblique first endface and an opposite flat endface, said second ferrule containing a fiber segment, the fiber segment having a first oblique endface coplanar with said second ferrule first oblique endface including a coating adapted to partially transmit said outgoing signal and to partially reflect said incoming signal into said detector, the oblique endfaces of said first and second ferrules being insertable into the receiver-splitter transverse bore such that the respective oblique faces are parallel to one another and the respective coatings are in physical contact and disposed in optical alignment with the detector disposed within the receiver-splitter cavity.
