Description

The 1245 Laser Transmitter is 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.

The 1245 meets all present Bellcore GR-253-CORE requirements, ANSI T1.117-1991 SONET single-mode, and the ITU-T G.957 and G.958 recommendations. (See Table 5 to select transmitters for the various SONET/SDH segments.)
