Introduction
tDoteck HD series digital video fiber optic transmission system can transmit one HD-SDI(1483.5M/1485Mbps)high definition digital video, or one SD-SDI(143M/177M/270M/360M/540Mbps)standard definition digital video or one DVB-ASI stream and one reverse control data RS232 through one single mode fiber or multimode fiber with the standards of SMPTE259M, SMPTE297M, SMPTE310M, SMPTE305M (SDTI).
tDue to the advanced digital fiber optic transmission technology, almost you need not make any adjustments, simple to set up, easy to operate.
tDoteck HD series transmitter provides one HD-SDI input, and one loop-through for local monitoring. The receiver outputs 2-way parallel HD-SDI digital video.
tDoteck HD series transmitter equipped with auto-cable equalization circuit, and cable driver circuit available at receiver.
tDoteck HD series, both at the transmitter and receiver, signal jitter elimination circuit available, to ensure high quality signal transmission over long distance fiber cable.
tDoteck HD series uses 3.3V power supply system, low power consumption.
