VCL-2486-G, GPS Receiver: Time Distribution Unit

Description

VCL-2486-G, GPS Receiver provides up to 16 x IRIG-B Outputs, or any “mix” of IRIG-B, 1PPS and NMEA Outputs. It can be also distribute IRIG-B signals over optical fiber(s) to extend the reach of these signals and distribute them over a large installed area using VCL-2728, remote optical fiber IRIG-B distribution terminals. VCL-2486-G, GPS / GNSS Receiver, Time Distribution Unit provides IRIG-B un-modulated / modulated, 1PPS, NMEA (0183) and NTP outputs along with a range of IRIG-B ports including RS-422, RS-232, RS-485, IRIG-B optical, RJ45, BNC.

The VCL-2486-G, GPS Receiver, Time Distribution Unit is designed to provide up to 16 outputs of Pulse and / or NMEA-0183 and / or 1 PPS and / or IRIG-B un-modulated / modulated and / or NTP (mix and match) that is locked to a GPS / GNSS Reference to provide time synchronization to private networks such as Railways and Metro (ticketing and platforms) networks, Airports and Air-Traffic Control facilities, Electric Sub-Stations, Power Distribution and Transmission companies, Oil and Gas Utilities, ISPs and Cable TV networks as well as to Campus networks.
