LDMB

Lightem Systems LDMB series digital video and analog audio or AES/EBU digital audio fiber optic transmission system transmits X SD -SDI(143M/177M/270M/360M/540Mbps) standard definition digital video and up to X analog audio or AES/EBU digital audio over one single mode fiber or multimode fiber. Lightem Systems LDMB series transmitter provides X SDI and X analog audio or X AES/EBU digital audio input, and one SDI loop-through for local monitoring. The receiver outputs two 2-way parallel SDI digital video and X analog audio or X AES/EBU digital audio.
Thanks for the auto-cable equalization, cable driver circuit and signal jitter elimination circuit, high quality signal transmission over long distance fiber cable is realized.
