1 Channel IEEE C37.94 to E1 Converter

View : 33
Type : E1 to Fiber Etherne
Description :

The C37.94 optical fiber interface conforms to the IEEE C37.94-2002 standard, the optical fiber interface between N*64K remote protection multiplexing equipment.

Overview

The C37.94 optical fiber interface conforms to the IEEE C37.94-2002 standard, the optical fiber interface between N*64K remote protection multiplexing equipment, realizes the interface conversion from the optical fiber interface in the substation to the E1 communication link, and can pass PDH, SDH, G.SHDSL and other E1 transmission equipment for transmission.

Features

Integrated circuit based on independent copyright,

Realize the interface conversion of one IEEE C37.94 in one E1, and can transmit through E1 transmission equipment such as PDH, SDH, G.SHDSL;

The E1 interface supports adaptive 120Ω/balanced and 75Ω/unbalanced impedances at the same time, no need to set any more;

After rigorous system testing and actual verification, it fully complies with ITU-T G.703, G.704 IEEE C37.94 protocols.

AC 220V, DC-48V, DC+24V, DC power supply and DC-48V/DC24V power supply have automatic polarity detection function, and dual power backup is possible;
