The VCL-2711, IEEE C37.94 over Ethernet / MPLS-TP / IP-MPLS Transmission Equipment is a ruggedized, robust and sub-station-hardened transmission equipment which converts and transmits up to four IEEE C37.94 Interfaces over an Ethernet / MPLS-TP / IP-MPLS link with “SDH / SONET like” performance. The VCL-2711 units must be always used in pairs, with one unit installed on each end of the Ethernet / MPLS-TP / IP-MPLS transmission link.
The VCL-2711, IEEE C37.94 over Ethernet / MPLS-TP / IP-MPLS equipment can be used in a point-to-point, or a point-to-multipoint topology with “zero” bit-errors and almost “zero” jitter or wander when used its integrated GPS (ITU-T G.811) compliant primary reference clock. Other clock synchronization options include an internal OCXO disciplined clock, external 1PPS clock, external 2.048MBits clock and an external 10MHz clock – any of which can be used to provide error-free C37.94 transmission over Ethernet / MPLS-TP / IP-MPLS links.
VCL-2711 is available in 1U high, standard 19-inch rack mount version.
The VCL-2711, IEEE C37.94 over Ethernet / MPLS-TP / IP-MPLS Transmission Equipment is designed to enable sub-stations to seamlessly migrate from SDH / SONET transmission networks to more efficient IP / MPLS transmission networks without incurring large capex or requiring the tiresome task of having to replace and rewire the existing C37.94 Relays which need to be inter-connected to remote substations inter-connected over Ethernet / MPLS-TP / IP-MPLS transmission links:
- End-to-end transmission delay (latency) of less than 6ms on IEEE C37.94 transmission link
- Symmetrical latency on the transmit and the receive paths
- SDH / SONET quality “jitter” and “wander” with “zero” transmission errors
- Multiple, integrated clock synchronization options
