Description

Picture of Digital Fiber Optic Cellular RepeatersDigital Fiber Optic Repeater is designed to solve problems of weak mobile cellular signal in the place that is far away from the Base Station (BTS) and has fiber optic cable network underground based on DSP technology. The Digital Fiber Optic Repeater system consists of two parts: Donor Unit and Remote Unit. The Donor Unit captures the BTS signal via direct coupler closed to BTS, the converts it into optic signal and transmits the amplified signal to the Remote Unit via fiber optic cable. The Remote Unit will reconvert the optic signal into RF signal and provide signal to the areas where cellular network coverage is inadequate. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
As per the method of receiving BTS signal by the Donor Unit, two types of FOR are available:

  • Cable-Access FOR: receive signal from BTS via a direct coupler closed to the BTS (recommended);
  • Wireless-Access FOR: to receive BTS signal via a Donor Antenna (applicable when no fiber optic cable connecting to the BTS); can be sorted into 2 sub-categories: Band-Selective and Channel-Selective.

Features
  • Single/Dual/Tri Band (GSM/DCS/UMTS/LTE FDD) is available
  • One Master Unit can drive up to 24 Remote Units
  • In-built AGC & ALC function be able to ensure easy installation without setting
  • Compact size and light weight, easy to install
  • Output power +30dBm - +43dBm for large coverage application
  • Filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
  • Built-in wireless modem (Option) for remote monitoring by SMS
  • Details repeater parameters and status can be monitored by software
  • High gain linear power amplifier technique with reliable performance

Application
To expand signal coverage of fill signal blind area where signal is weak or unavailable.
  • Outdoor/Rural: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages, ……
  • Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Packing Lots, ……
