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