C37.94-E1 Converter – PKUS EO1/EO2

  • UNITEL ENGINEERING (RUSSIA)

PKUS EOx is an electro-optical multiplexer between one G.703/704 E1 and single/dual/quad IEEE C37.94 interface. It connects to relay protection equipment including Line Differential Protection Relays and Teleprotection Units with C37.94 or optical E1 (CMI, G.704) ports to telecom networks via electrical E1 (HDB3, G.704)
