C37.94-E1 O/E Converter

Converters for interfacing teleprotection equipment with IEEE C37.94 or optical E1 ports to communication networks using electrical E1. It can convert single and dual/quad C37.94 or optical E1 to electrical E1 interface. The IEEE ports are fully mapped into G.703 standard frame structure of the E1 port, allowing for further SDH/ PDH multiplexing and de-multiplexing. Successfully connect with line differential protection relay of Toshiba, GE, AB, Siemens, SEL,…


Robust utility communications enable protection systems to clear a line fault within the shortest possible time or to isolate primary equipment directly affected by the fault while maintaining the reliable transmission and distribution of electrical power. Teleprotection provides fast, highly reliable and secure relay protection channels for command-based over dedicated optical fibers, communication networks and power lines. Support transmits and receives 16 commands via telecom networks (SDH/PDH, MPLS, etc.) with C37.94 and E1 interfaces or direct optical fibers (the distance of up to 240 km). Optional IEC 61850 protocol.
