ViaLite’s new Local Integrated GPS Splitter was designed to minimize rack space. Suitable to applications requiring a fan-out of GPS/GNSS signals within a single local area, the unit can accept optical inputs from up to four antennas.
Though it has a height of only one rack unit, the system is suitable for feeding timing and synchronization signals to single or multiple floors or rooms through 8 to 32 optical fiber links with no system loss.
Available with 1×8, 2×8, 4×8, 1×16 and 2×16 options, the easy-to-install GPS Splitter has a 1000-1800-MHz frequency range. Built-in simple network management protocol (SNMP) control is included as well as dual-redundant power supply units.
Typical application areas include data centers, banking institutions, scientific research establishments, cellular test environments, fixed satcom Earth stations and teleports, oil and gas platforms, and big data.
“Our new GPS Splitter was developed in response to customer demand across a wide range of sectors,” said ViaLite Product Manager John Golding. “We are pleased to have been able to meet their needs by providing a very high-quality product at a reasonable cost.”
