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.
