Introduction
tDoteck HD series digital video fiber optic transmission system can transmit one 1485Mbps HD-SDI high definition digital video, or one 270Mbps SDI standard definition digital video or one DVB-ASI stream through one single mode fiber or multimode fiber with the standards of SMPTE292M, SMPTE259M, SMPTE297M, SMPTE305M, SMPTE310M.
tDoteck HD series transmitter provides one HD/SD-SDI input, and one loop-through for local monitoring. The receiver output 2-channel parallel HD/SD-SDI digital video.
tDoteck HD series transmitter and receiver all have re-clocker chips to regenerate the signal.
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 5V power supply system, low power consumption.
