The device enables the conversion of fiber interfaces within a substation to E1 communication links, and facilitates transmission through E1 transmission equipment such as PDH, SDH, G.SHDSL, and others.
The C37.94 fiber interface conforms to the IEEE C37.94-2002 standard and is used for fiber interface communication between N*64K remote protection multiplexing devices. It enables the conversion of fiber interfaces within a substation to E1 communication links, and facilitates transmission through E1 transmission equipment such as PDH, SDH, G.SHDSL, and others.
● It implements the conversion between one channel of IEEE C37.94 and one channel of E1, enabling transmission through E1 transmission equipment such as PDH, SDH, G.SHDSL, and others.
● The E1 interface simultaneously supports adaptive 120Ω/balanced and 75Ω/unbalanced impedance without requiring additional configuration.
● It has undergone rigorous system testing and practical validation, fully complying with ITU-T G.703, G.704, and IEEE C37.94 protocols.
● The device supports AC 220V, DC-48V, DC+24V, and DC-48V/DC24V power supplies, featuring automatic polarity detection and the ability for dual power backup.
