1241/1243/1245-Type Uncooled Laser Transmitter
Features
s
Backward compatible with 1227/1229/1238-Type
Laser Transmitters
Space-saving, self-contained, 20-pin DIP
Uses field-proven, reliable InGaAsP MQW laser
Requires single 5 V power supply
SONET/SDH compatible
Uncooled laser with automatic optical power con-
trol for constant output power over case tempera-
ture range
No thermoelectric cooler required; reduces size
and power consumption
