  • SUN-PDH series Fiber Multiplexer is integrated service transmission equipment manufactured by our company. With its self-developed special-purpose integrated circuit. It combines standard 2M traditional TDM service interface with 10/100Base-Tx Ethernet data service interface, and convert the data into high-speed optical signals to transmit over fiber, making it possible transmitting both high-speed data service and traditional TDM service over the same pair of fibers, meeting user’s requirements for integrated access of high-speed data service and traditional TDM service with the minimal cost. The advanced dual-light-beam switching and restoration mechanism enables the equipment to achieve 1+1 protection for services.
