3.125 Gbps/channel 4-channel parallel optical transmitter andreceiver module with MT-RJ receptacle

摘要

This paper describes a 3.125 Gbps 4-channel parallel opticaltransmitter and a receiver module with MT-RJ receptacle designed for avery short reach OC-192 interface between a DWDM transponder and a corerouter. The discussion is addressed on the following key features: (1)4-channel 1310 nm FP-LDs with their anodes and cathodes separatedchannel-by-channel, (2) 4-channel passive optical alignment technology,(3) inter-channel crosstalk reduction technology in a Si optical bench,(4) low power consumption high speed LD driver and receiver LSIs. Theapplicability of newly developed 3.125 Gbps/ch 4-channel paralleloptical transmitter and receiver module to very short reach applicationhas also been demonstrated through a transmission experiment over a 500m length of GI-50 MMF (graded-index multi mode fiber)
