30Ch telephone fiber converter

Lightem LBV series Single core fiber Video/Audio/Data multimeter provides a convenient way to extend the Video link by coaxial to fiber media conversion. With choices of 1, 2, 4 and 128 channels, Lightem media converter is able to transmit 8 video channels via a single fiber (singlemode or multimode). Optional Data (RS232 or RS422 or RS485) and Audio is useful for system which involves voice as well as control for camera (Pan / Tilt / Zoom control) or keyboard for control. Industry standard Data protocol ensure the compatibility between various suppliers such as Bosch, Pelco etc.
