The Application of Parallel Optical Transmitter and Receiver Modules in Communication Subsystems

A new 12 channels parallel optical transmitter module in which a vertical cavity surface emitting laser (VCSEL) has been selected as the optical source is capable of transmitting 37.5 Gbps date over hundreds meters. A new 12 channels parallel optical receiver module in which a GaAs PIN (p-intrinsic-n-type) array has been selected as the optical receiver unit is capable of responding to 30 Gbps date. A transmission system based on a 12 channels parallel optical transmitter module and a 12 channels parallel optical receiver module can be used as a 10 Gbps STM-64 or an OC-192 optical transponder. The parallel optical modules and the parallel optical transmission system have passed the test in laboratory
