Introdution
tDoteck DMB series HD-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.
tDue to the advanced digital fiber optic transmission technology, you need not make any adjustments, simple to set up and easy to operate.
tDoteck DMB series HD-SDI digital video and audio fiber optic transmission system, and one SDI loop-through for local monitoring. The receiver outputs 2-way parallel SDI digital video.
tDoteck DMB series transmitter equipped with auto-cable equalization circuit, and cable driver circuit available at receiver.
tDoteck DMB series, both at the transmitter and receiver, signal jitter elimination circuit available, to ensure high quality signal transmission over long distance fiber cable.
