وصف
ال Triple Band Fiber Optic Repeater is designed to solve problems of weak mobile signal in the place that is far away from the Base Transceiver Station (بتس) 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 Donor antenna 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 BتS via the opposite direction.
- Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding
- Omni-directional antenna can be adopted to expand more coverage
- 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 Donor Unit can support up to 4 Remote Units to maximize utilization of fiber optic cable
- USB port provides a link to a notebook for local supervision or to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise repeater‘s working status and download operational parameters to the repeater
