VCL-GPS-2145-LC
GPS Primary Reference Clock and NTP Server
Product Overview
Orion Telecom Networks Inc. offers VCL-2145-LC (VCL-GPS-2145), GPS Primary Reference Clock is a high precision frequency synchronization solution which may be used to provide ITU-T, G.811 Primary Reference Clocks which are referenced to a GPS source.
The VCL-2145-LC (VCL-GPS-2145), GPS Primary Reference (PRC) Clock is specifically designed for frequency synchronization of 2G, 3G, HetNet and LTE mobile telecommunications networks as well as backhaul wire-line SDH / SONET and Synchronous Ethernet networks. It may be also used by Railways, Airports (and air-traffic control), Power generation and distribution companies and other Utility companies who require a highly precise G.811 frequency synchronization locked to a GPS Reference.
The VCL-2145-LC (VCL-GPS-2145) locks to a GPS reference to provide multiple G.811 / Stratum 1 quality frequency outputs. The VCL-2145-LC is also equipped highly accurate, low-noise OCXO / Rubidium oscillator which provides a high stability, ITU-T G.812 compliant holdover clock that is typical of a Network SSU in the event of unavailability of the GPS signal, or GPS antenna failure.
