System on an SDH SFP line of miniature Ethernet remote access devices

MultiRate SFP transceiver provides a fully SONET compliant interface between the SDH SFP photonic layer and the electrical layer. Its microprocessor - based modular design implements all features specified in the SFP MSA compatible 2-wire Serial Digital Diagnostic Monitoring Interface for Optical Transceivers is a network line with transmission speeds of up to 2488.32 Mbit/s (payload: 2405.376 Mbit/s; overhead: 82.944 Mbit/s).OC-3/STM-1 is a network line with transmission speeds of up to 155.52 Mbit/s (payload: 148.608 Mbit/s; overhead: 6.912 Mbit/s, including path overhead) using fiber optics. Depending on the system OC-3 is also known as STS-3 (electrical level) and SDH SFP. These modules are also used for Fast Ethernet application. The SFP modules are high performance, cost effective for serial optical Tel communications applications that range from 125 Mb/s to 622 M b/s. They are designed to provide SDH SFP compliant links for both short and intermediate reach links.  The Modules adds digital diagnostic monitoring to standard SFP functionality, enabling fault isolation, components monitoring and failure
