Extra Engineering Notes
C37.94 interfaces, as defined by IEEE C37.94TM-2002, are optical interfaces that transfer relay protection information between teleprotection devices and digital multiplexers over optical fiber channels. The data frame format and rate range for C37.94 connections are both standard.
C37.94 interfaces connect users' relay protection devices to the router, allowing data services for leased line connectivity to be transmitted transparently.
The most frequent channels used to transmit teleprotection information are 64 kbit/s and 2 Mbit/s. The low transmission bandwidth of 64 kbit/s channels, on the other hand, hinders the delivery of teleprotection information. Furthermore, when 64 kbit/s channels are employed, digital multiplexers often require 64 kbit/s codirectional interfaces that must be connected to the electric power communication networks via pulse code modulation devices. This method lengthens the signal transmission time and introduces more interference.
