Product Description
TETRA cable-access MDAS Fiber Optic Repeater is used to enlarge the signal of TETRA equipment. The Master Optical Unit System captures the BTS signal of TETRA and converts it into optic signal and transmits the amplified signal to the Remote Optical Unit via fiber optic cables. The Remote Optical Unit will reconvert the optic signal into TETRA signal and then converse Downlink Amplifier and provide the signal to the areas where net work coverage is inadequate.
And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction. The distribution system by our company independent research and development is composed by Master Optical Unit and Remote Optical Unit. The internal module is integrated, the highly integrated technology is improve the stability of the equipment.
