8E1 plus 10/100M ethernet converter
SPC-155 series is integrated service transmission equipment manufacturedby Beijing Spacecom Co., Ltd. with its self-developed special-purpose integratedcircuit.It combines standard 2M traditional TDM service interface with 10/100Base-Tx Ethernetdata service interface and convert the data into high-speed optical signals to transmitover fiber, making it possible transmitting both high-speed dat service and traditionalTDM service over the same pair of fibers, meeting users requirements for integratedaccess of high-speed data service and traditional TDM service with the minimal cost.The advanced dual-light-beam switching and restoration mechanism enables the equipmentto achieve 1+1 protection for services.
