DMB 3G-SDI+Audio/Optical Fiber Transmission System

Doteck DMB series SDI digital video and audio fiber optic transmission system can transmit one SD-SDI(143M/177M/270M/360M/540Mbps) standard definition digital video over one single mode fiber or multimode fiber. Due to the advanced digital fiber optic transmission technology, you need not make any adjustments, simple to set up and easy to operate.

Doteck DMB series SDI digital video and audio fiber optic transmission system is equipped with one SDI loop-through for local monitoring at the transmitter with auto-cable equalization circuit. The receiver outputs 2-way parallel SDI digital video with 75 ohms cable driver. Both, transmitter and receiver, have signal jitter elimination circuit available, to ensure high quality signal transmission over long distance fiber cable.
