IEEE C37.94 optical to E1 converter

IEEE C37.94 to E1 converter

INFORMATION

Functions:

The C37.94 fiber optic interface complies with the IEEE C37.94-2002 standard, and is a fiber optic interface between2048K remote protection multiplexing equipment, achieving interface conversion from the fiber optic interface in the substation to the E1 communication link, and can be transmitted through E1 transmission equipment such as PDH, SDH, G.SHDSL, etc;

Feature:

Integrated circuits based on independent copyright
Implement interface conversion of one IEEE C37.94 in one E1 and transmit it through E1 transmission devices such as PDH, SDH, G.SHDSL, etc;
The E1 interface supports both adaptive 120 Ω/balanced and 75 Ω/unbalanced impedances, without the need for further settings;
After strict system testing and practical verification, it fully complies with the ITU-T G.703 and G.704 IEEE C37.94 protocols.
AC 220V, DC-48V, DC+24V, DC power supply, and DC-48V/DC24V power supply have polarity automatic detection function, which can be backed up by dual power supplies;
