Fiber Optic Cellular Repeaters (FOR) system 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. The Fiber Optic Repeater (FOR) 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.

• Comply with relevant regulation spectrum usage
• Aluminum-alloy casing with IP65 protection and compact design, cool system without fan
• ALC and AGC to ensure stable operation
• Option channel Selective 1, 2, 4, 6, 8 for Wireless Access application
• Easy to install on wall or pole
• One Donor Unit can support up to 4 Remote Units to maximize utilization of fiber optic cable
• Max transmission distance between Donor Unit and Remote Unit is 20KM
• Adopting WDM module to realize long distance transmission
• 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

• Outdoor/Rural: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages, etc..
• Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Packing Lots, etc.

• Underground fiber optic cable network already exists beneath the area to be covered;
• There is huge obstructive terrain between the BTS and the area to be covered;
• The distance between the BTS and the area to be covered is 20KM around.
