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

SONET,SDH system from intra-office to long­leach application fully line up
Low cost and Low power consumption
Multisourced 20-Pin DIP with pigtail fiber
Single +5V power supply and P-ECL compatible
input and output

Operating case temperature range -40 to 85°C
With clock recovery and digital alarm function
