IEEE C37.94 to E1, Optical Transmission, IP/MPLS/Ethernet Solutions
VCL IEEE C37.94 protocol equipment provides various solution options for Power Utility applications. VCL IEEE C37.94 equipment offers ruggedized, robust and substation-hardened transmission solutions which converts IEEE C37.94 to E1 (2.048 Mbps), convert IEEE C37.94 optical fiber multi-mode to single-mode for up to 50dB optical link loss budget (i.e., a typical reach of approximately 160 KM or 100 miles) and IEEE C37.94 protocol over IP/MPLS / MPLS-TP transmission links.
VCL IEEE C37.94 protocol equipment includes precise clock recovery and clock re-generation functions which allows the transmission of IEEE C37.94 channels over an E1/SDH or IP/MPLS / MPLS-TP network for error-free transmission with symmetrical transmission latency with zero transmission errors. Product applications are used to interface with current differential protection and distance protection relays.
