Patent ID: 6954592

Claim:
A bi-directional optical transceiver module for bi-direction optical communication over a single optical fiber, the bi-directional optical transceiver module comprising: an optoelectronic transmitter to generate a first light beam to couple into the single optical fiber; an optoelectronic receiver to receive a second light beam decoupled from the single optical fiber; an optical block having a first opening, a second opening, and an optical filter, the optoelectronic transmitter coupled into the first opening to form a first optical axis, the optoelectronic receiver coupled into the second opening to form a second optical axis, the single optical fiber aligned with the first optical axis, the optical filter to pass through the first light beam on the first optical axis from the optoelectronic transmitter into the single optical fiber and to redirect the second light beam from the single optical fiber on the first optical axis into the second optical axis and the optoelectronic receiver; a printed circuit board (PCB) coupled to the optoelectronic transmitter and the optoelectronic receiver, the printed circuit board to couple to a host system and transceive electrical signals, the printed circuit board including a connector to couple to a connector of the host system; and a fiber optic receptacle to receive and hold a connecter on the single optical fiber aligned with the first optical axis; wherein the optical block is an integrated optical block having a third opening for insertion of the optical filter with a slot at one end thereof, the slot to receive the optical filter.
