EMTS Telecom Services Fiber Optic Repeating system is the best and more reliable solution to extend and improve VHF LMR analog or digital telecommunication systems' coverage area. The Fiber Optic Repeating system consists of two modules, Master and Slave. The Master module (FMU) is connected to a Channel Selective BDA receiving signals from the BTS, while the Slave (FRU) module provides coverage in the service area. Fiber Optic Repeaters amplify in directions, uplink and downlink a continuous bandwidth, factory tuned. Its rugged construction and easy field maintenance reduce operational costs and ensure a high MTBF. The EMTS Fiber optic repeating system is a cost-effective and practical solution for extending signal coverage in subways, tunnels, and Indoor or outdoor distribution systems.

in-building coverage. Regardless of the technology or frequency, EMTS can provide customized coverage solutions that address any combination of unique and complex network needs for Wireless Networks.

Key Features
