Abstract
A multi-channel receiver optical subassembly (ROSA) including at least one sidewall receptacle configured to receive and electrically isolate an adjacent multi-channel transmitter optical subassembly (TOSA) is disclosed. The multi-channel ROSA includes a housing with at least first and second sidewalls, with the first sidewall being opposite the second sidewall and including at least one sidewall opening configured to fixedly attach to photodiode assemblies. The second sidewall includes at least one sidewall receptacle configured to receive at least a portion of an optical component package, such as a transistor outline (TO) can laser package, of an adjacent multi-channel TOSA, and provide electrical isolation between the ROSA housing and the TOSA within an optical transceiver. The sidewall receptacle can include non-conductive material in regions that directly or otherwise come into close proximity with the optical component package of the adjacent TOSA.
