MTRS-2T77-AAA is a high performance, cost  effective module, which is supporting multi rate 9.95Gbps to 11.3Gbps with CDR, 8.5Gbps by pass CDR, and transmission distance up to 80km on  SM fiber. The transceiver consists of two sections:  The transmitter section incorporates a laser driver and a TTOSA. The receiver section consists of an APD photodiode integrated with a transimpedance  preamplifier (TIA). The module is hot pluggable  into the 20-pin connector. The high-speed  electrical interface is base on low voltage logic, with nominal 100ohms differential impedance and  AC coupled in the module.
