MTRA-3T33 is a high performance, cost effective modules, which is supporting Multi Rate 9.8304 Gbps to 25.78125Gbps, and transmission distance up to 10km on SM fiber. The transceiver consists of two sections: The transmitter section incorporates a laser driver and a DSDBR TTOSA. The receiver section consists of a PIN integrated with a transimpedance preamplifier (TIA) and a Limitting Amplifier. 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.
