Overview

  • Compatible with Multisource Agreement (MSA) for SFP Transceivers
  • 75Ω Coaxial Line Interface Compliant with ITU-T G.703/G.783 and Telcordia GR-253 for CMI Coded 155Mbps Electrical Interfaces
  • ITU-T G.783-Compatible LOS Detect
  • Transmit Power-Down Supported
  • Handles Over 12.7dB of Cable Loss
  • Extended Temperature Operation: -10°C to +85°C
  • 1.0/2.3 Coaxial Interface (Type A- or D-Coupling)
  • Low Power Dissipation (0.6W typ)

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.
