ViaLite has introduced new RF over fiber (RFoF) GPS extension kits that enable remote GPS/GNSS signals to be received where no GPS reception is available. They are ideal for delivering timing signals to building interiors and underground facilities such as tunnels and mines.
Essential for timing and synchronization applications, the GPS or derived timing reference signals are used for Base Station timing and by Network Time Protocol (NTP) server networks to maintain the extremely accurate clock systems required by today’s computer networks.
ViaLite’s new kits can carry the signals as far as 10 km as standard, and even longer distances of more than 50 km are possible. Unlike traditional coaxial cable, signal transmission over optical fiber can be achieved with no RF loss and zero introduction of noise.
Suitable for GPS (L1, L2, L5), GALILEO, GLONASS and BeiDou bands, they are compatible with leading providers’ NTP servers, including Microchip and Meinberg.
Among the many areas of application for the kits are telco operators, telecom synchronization, banking and finance, data centers and defense.
Amair Khan, ViaLite Business Development Manager, said: “The kits were developed to make it easier for customers around the world to order under a single part number and not to have to worry about regional power supply differences. They are a plug-and-play solution that is simple and very effective in bringing GPS signals to areas where coax fails to do this.”
The transmitter units have either a 5 V or 12 V DC voltage feed for powering the antenna via an RF SMA connector. A compact integrated GPS splitter for the receiver side is also available, with 1-4 RFoF receivers and 8-32 outputs and taking up only 1U of rack space.
