STM1E-SFP

155Mbps Copper Transceiver

Industry's First SFP for STM-1e Copper Interfaces


Description

The STM-1e SFP is a small form-factor pluggable (SFP) transceiver compatible with the multisource agreement (MSA) for SFPs. The module uses Teridian Semiconductor’s latest generation of line interface units (LIUs) for 155Mbps electrical SONET/SDH interfaces (STM-1e). It also includes all the necessary components for interfacing to 75Ω telecommunications coaxial cable.

The 78P2351R physical layer IC includes clock and data recovery in both directions, an adaptive receiver equalizer, and a CMI encoder/decoder for transparent NRZ-to-CMI line code conversion. It provides receive loss-of-signal (LOS) detection and the option to disable (and three-state) the transmit driver. A serial interface provides access to an on-board EEPROM for identification information.
