High Performances Fiber Optic Repeating System

Download Datasheet (PDF)

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.

Key Features

  • Fiber Optic DAS is a reliable solution to extend and improve the coverage area of UHF/LMR/DMR Networks
  • Consists of two main modules: Master Unit (MU) and multiple Remote units (RU)
  • Supports all combinations of UHF/LMR/DMR 400MHz bands
  • 33, 37, 40, and 43dBm composite power types meet LMR/DMR system standards
  • Easy field installation and maintenance reduce rollout and operational costs
  • The signal transmission in the fiber optic repeater would not be disturbed by outside influences
  • Provide quick RF coverage service to your LMR/DMR Base-Station
  • Compact Size and High Performance in a waterproof enclosure suitable for outdoor and indoor installations
  • Remote unit design for wall mounting & Base unit design for 19 inch rack
