The TETRA Single Band Fiber Optic BDA(Bi-Directional Amplifier) is designed to solve problems of weak radio network 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: Donor Unit and Remote Unit. The Donor unit captures the BS signal via direct coupler closed to BS, 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 BS via the opposite direction.
Feature:
Aplications:
To expand signal coverage or fill signal blind area where radio network signal is weak or unavailable.
