The 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: Master Unit(MU) and Remote Unit(RU). The MU captures the BTS signal via donor antenna, then converts it into optic signal and transmits the amplified signal to the RU via fiber optic cable. The RU 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. 

• Tx/Rx control and alarm messages can be transmitted via one fiber optic cable

• Adopting WDM module to realize long-distance transmission

• Stable and improved signal transmission quality

• One MU can support up to 8 RUs to maximize utilization of fiber optic cable(A star topology is supported between MU and RUs)

• USB 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
