Modules adds digital diagnostic monitoring to standard SDH SFP

The SFP modules are high performance, cost effective for serial optical Tel communications applications that range from 125 Mb/s to 2.7 Gb/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 SDH SFP functionality, enabling fault isolation, components monitoring and failure prediction capabilities. The modules conform to the function specification of ITU-T G.957 standard and fully Class 1 CDRH/IEC 825.
This product is provided to ODM customers. Designated the SFP-155E, this transceiver uses 75-V coax cable with DIN 1.0/2.3 connectors (see the figure). It conforms to the synchronous digital hierarchy (SDH) STM-1 standard (similar to Sonet OC-3), which delivers a data rate of 155 Mbits/s on coax up to 100 meters long. Additionally, the module fully complies with ITU-T G.703 (ES1) recommendations. It's designed to meet ITU-T G.825 jitter specifications as well.

The TX_Fault output contact is an open drain/collector and shall be pulled up to the Vcc_Host in the host with a resistor in the range 4.7-10 kΩ. TX_Disable is a module input contact. When TX_Disable is asserted high or left open, the SDH SFP Module output shall be turned off. This contact shall be pulled up to VccT with a 4.7 kΩ to 10 kΩ resistor The receiver converts 10Gbit/s serial optical data into serial PECL/CML electrical data. An open collector compatible Loss of Signal is provided. Rx_LOS when high indicates an optical signal level below that specified in the relevant standard.
