Description

The 1241/1243/1245-type Laser Transmitters are designed for use in transmission systems and high speed data communication applications. Used in intraoffice and intermediate-reach applications, the transmitters are configured to operate at SONET rates up to OC-12, as well as at ITU-T synchronous digital hierarchy (SDH) rates up to STM-4. Specific versions are also capable of operating up to 1062.5 Mbits/s.

Features

■ 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 control for constant output power over case temperature range
■ No thermoelectric cooler required; reduces size and power consumption
■ Uses low-power dissipation CMOS technology
■ Qualified to meet the intent of Bellcore reliability practices
■ Operates over data rates to 1062.5 Mbits/s (NRZ)
■ Operation at 1.3 µm or 1.55 µm wavelength
■ Typical average output power options of –11 dBm, –8 dBm, –5 dBm, –2 dBm, and 0 dBm
■ ECL compatible, differential inputs
■ Operating temperature range of –40 °C to +85 °C
■ Transmitter-disable option
