Benefits
Description
The
STM1E-SFPxx
is a Small Form-factor Pluggable (SFP) module compatible with the Multi Source Agreement
(MSA) for SFP transceivers. The module utilizes the latest generation of Line Interface Units (LIUs) for 155 Mbit/s
electrical interfaces (STM-1e, ES1) from Teridian Semiconductor Corporation (TSC). It also includes all the
necessary components for interfacing to 75Ω telecommunications coaxial cable.
The Teridian 78P2351R physical layer IC includes Clock & Data Recovery in both directions and a CMI
encoder/decoder for transparent NRZ to CMI line code conversion. It provides Receive Loss of Signal (LOS)
detection for electrical CMI interfaces and the option to disable (and tri-state) the transmit driver. A serial
interface provides access to an on board EEPROM for identification information.
