VCL-2145-D, GNSS (GPS-GLONASS-SBAS) PRIMARY REFERENCE CLOCK
Orion Telecom Networks Inc. offers its VCL-2145 (VCL-2145-D) is a high-performance, GNSS (Global Navigation Satellite System) Primary Reference Clock that provides ITU-T G.811 Primary Synchronization Frequency References which are locked to a user selected GNSS (GPS-GLONASS-SBAS) Satellite source.
The VCL-2145 (VCL-2145-D) Satellite Receiver also has an integrated, high bandwidth NTP Server engine that is capable of handling up to 3000 NTP requests per second. Multiple IRIG-B Outputs are also provided to synchronize local clock (time-of-day) display units as well as RTUs to a central timing source with nanosecond accuracy.
The VCL-2145 (VCL-2145-D), Satellite (GNSS) 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 not only require highly precise G.811 frequency synchronization locked to a GNSS Reference but who also need to provide an accurate time-of-day reference in their networks.
The VCL-2145-D is always locked to a user selected satellite (GNSS: GPS-GLONASS-GAGAN) reference to provide multiple G.811 / Stratum 1 quality frequency and time-of-day (IRIG-B and NTP) outputs. The VCL-2145 is also equipped highly accurate, low-noise OCXO / Rubidium oscillator which provides a high stability holdover clock that is typical of a Network SSU in the event of the GNSS signal, or its antenna failure.
