Product Description

Fiber Optic GSM CDMA WCDMA Repeater Digital truncking communication transmitter signal repeater
Product Description

Fiber Optic Repeater is designed to solve problems of weak mobile phone signal in such place: far away from the BTS (Base Transceiver Station) and has fiber optic cable network underground.


The whole FOR system consists of two parts: Donor Unit and Remote Unit. They transparently convey and amplify the wireless signal between the BTS (Base Transceiver Station) and mobiles via fiber optic cables.


The Donor unit captures the BTS signal via a direct coupler closed to the BTS (or via open air RF transmission through the Donor Antenna), then converts it into optic signal and transmits the amplified signal to the Remote Unit via fiber optic cables. 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 re-transmitted to the BTS via the opposite direction.

Fiber optic signal booster Features:
1. High isolation full duplex design, Wave Division Multiplexing design, easy to install.
2. Low noise figure, high receive sensitivity.
3. With ALC and MLC function to ensure stable output power and easy installation and commissioning.
4. Scientific and perfect circuit design, and adopting advanced amplifier device, ensure the repeater station
equipment low power consumption, environmental protection and energy saving.
5. Modular structure design, according to need, easily to upgrade the system by increasing the module,
expand the business.
6. High Q cavity filter and SAW surface acoustic wave filter, high out of band rejection.
7. Adopt the world's most advanced high linearity, low intermodulation LDMOS power amplifier.
8. Perfect remote and local network monitoring function.
9. Waterproof design work for all weather indoor and outdoor.
