We provide GPS active splitter: GS12, GS14, GS18 , which can provides sharing solution of a GPS antenna for mobile communication base station, trunking communication base station, simplifying the network structure to the maximum extent . Multiple systems share a set of timing antenna and line, reducing construction costs and system maintenance costs . Not only our communications timing solutions apply to LTE laboratory and production line , but also our splitters（ GS12, GS14, GS18 ）start large-scale applying to the global LTE networks from2010 . Timing system is stable and reliable, so the network degree of optimization in maximum .

GEMS’s GPS-over-Fiber clock synchronization distribution system (remote fiber timing distribution system) adopts intelligent shunting system and distributes the timing signals of GPS active antennas to multiple BBUs.
