VCL-GPS-2145
Product Overview

VCL-GPS-2145Orion Telecom Networks Inc. offers VCL-GPS-2145, PTP Grandmaster is a high precision, yet cost efficient, ToD (Time of Day) and PRC (Primary Reference Clock) frequency synchronization solution which can be used to synchronize the time-of-day and frequency across all nodes of the network (using IEEE-1588 Master-Slave protocol) from its highly accurate GPS referenced source. The VCL-GPS-2145, PTP Grandmaster also has an integrated, high bandwidth NTP Server engine that is capable of handling up to 6000 NTP requests per second. Multiple IRIG-B Outputs are also provided to synchronize local clock displays as well as RTUs to a central timing source with nanosecond accuracy.

Data Sheet (PDF)

The GPS-2145, PTP Grandmaster is specifically designed for the synchronization of 2G, 3G 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 (including air-traffic control), power generation and distribution companies and other utility companies who not only require a highly precise time-of-day and frequency synchronization locked to a GPS Reference but who also need to distribute highly precise time-of-day and frequency synchronization across all nodes of their networks.

The equipment conforms to and provides a G.811/Stratum 1 quality synchronization (GPS locked) reference while providing multiple time (IRIG-B) and frequency outputs that are usually required by the users of such equipment.

The GPS-2145, PTP Grandmaster is equipped with an integrated GPS receiver and a highly accurate, low-noise OCXO, which provides a high stability, G.812 compliant holdover quality typical of an SSU in the eventuality of the GPS signal or its antenna failure. Rubidium (RbXO) Clock option is also available for applications that have more stringent compliance requirements.
