The VHF Fiber Optic Repeater (FOR) is designed to solve problems of
weak mobile signal in the place that is far away from the Base
Transceiver Station (BTS) and has fiber optic cable network
underground. The system consists of two parts: Donor Unit and
Remote Unit. The Donor unit captures the BTS signal via direct
coupler closed to BTS, then 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 the signal to the areas where network coverage
is inadequate. And the mobile signal is also amplified and
retransmitted to the BTS via the opposite direction. Feature: 1.
Aluminum-alloy casing with IP65 protection has high resistance to
dust, water and corroding. 2. Supporting VHF system. 3. Tx/Rx
control and alarm messages to be transmitted via one fiber optic
cable. 4. Adopting WDM module to realize long-distance
transmission. 5. Stable and improved signal transmission quality.
6. One MU supporting up to 4 RUs to maximize utilization of fiber
optic cable. 7. RJ45 port provides a link to a notebook for local
supervision or IP Based NMS(Network Management System) that can
remotely supervise repeater's working status and download
operational parameters to the repeater Via Ethernet or LAN To
expand signal coverage or fill signal blind area where signal is
weak or unavailable. 1. Outdoor: Airports, tourism regions, golf
courses, tunnels, factories, mining districts, villages, … 2.
Indoor: Hotels, exhibition centers, basements, shopping malls,
offices, parking lots, … Specification:
