| MITSUBISHI (OPTICAL DEVICES) MF-156DS-TR123-030/040/050 SONET/SDH TRANSCEIVER DESCRIPTION This product is designed to provide high optical performance for SDH STM-1/SONET OC-3. Transmitter uses uncooled laser in a hermetic pigtail coaxial module with drivered by specific integrated circuit. Receiver uses PIN preamp in a hermetic pigtail coaxial module and integrated circuits for reshaping, retiming and regenerating optical signal. FEATURES Tx + Rx combined Full SONET/SDH line up Low voltage, low power consumption, low cost 20-PIN DIP with fiber pigtail Single +3.3V power supply and P-ECL compatible input and output Temp range:-40 to 85 C Clock recovery APPLICATION Short haul and long haul telecommunication systems for SDH STM-1 / SONET OC-3. ABSOLUTE MAXIMUM RATINGS Stress below listed absolute maximum rating may cause permanent damage to the transceiver. Th is is a stress o nly and functional operation of the transceiver at these or any other conditions in excess of those given in the operational sections of this data sheet is not implied. Exposure to Absolute Maximum Rating for extended periods may affect transceiver reliability.
