High Performances Fiber Optic Repeating System
The EMTS Telecom Services Fiber Optic Repeating system is the best and more reliable solution to extend and improve the coverage area of LMR 400MHz (TETRA, APCO-25 or Analog systems) telecommunication systems. The Fiber Optic Repeating system consists of two modules, Master and Slave. The Master module can be used directly coupled from BTS or can be connected to a RF Repeater receiving signals from the BTS, while the Slave (Remote) module provides coverage in the service area. Fiber Optic Repeaters amplifies in directions, uplink and downlink a continuous bandwidth, factory tuned. Its rugged construction and easy field maintenance reduces operational costs and ensures 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.
