This 2.5 Gb/s receiver module is designed for use in long haul SONET, SDH, and DWDM systems. The InGaAs Avalanche Photodiode (APD) detector, FRM5W232BS, incorporates a GaAs IC transimpedance preamplifier and a thermistor in a mini-DIL type package. Featuring high sensitivity at 㪺 dBm (typical) and a high differential electrical output, this device contains a nominal 10 kohm integral thermistor that allows accurate monitoring of the APD temperature and facilitates the design of the APD bias control circuits. The integrated transimpedance amplifier is designed with the standard power supply of +3.3 V resulting in small power consumption (0.15 W).
