Patent ID: 7178996

Claim:
An optical transceiver device for mounting in a host system, which includes a host printed circuit board, comprising: a module housing with dimensions the same as an optical transceiver of a first form factor for mounting in a guide rail or cage in the host system; a module printed circuit board mounted in the module housing; a module electrical connector extending from the module housing for electrically connecting the module printed circuit board to the host printed circuit board; and a plurality of transceivers with dimensions of an optical transceiver of a second form factor, smaller than the first form factor, mounted in the module housing electrically connected to the module printed circuit board, each transceiver including an optical connector for receiving optical fibers, a receiver optical sub-assembly for converting received optical signals into electrical signals, a transmitter optical subassembly for converting electrical signals into optical signals, and a transceiver electrical connector; wherein the module printed circuit board transmits signals between the plurality of transceivers and the module electrical connector.
