Introduction
tDoteck 3G8 series digital video fiber optic transmission system can transmit eight 2970Mbps 3G-SDI high definition digital videos, or eight 1485Mbps HD-SDI high definition digital videos, or eight 270Mbps SDI standard definition digital videos or eight DVB-ASI streams through one single mode fiber or multimode fiber with the standards of SMPTE424M, SMPTE292M, SMPTE259M, SMPTE297M, SMPTE305M, SMPTE310M.
tDoteck 3G8 series transmitter provides 8-channel 3G/HD/SD-SDI input, and 8-channel loop-through for local monitoring. The receiver output 16-channel parallel 3G/HD/SD-SDI digital video.
tDoteck 3G8 series transmitter and receiver all have re-clocker chips to regenerate the signal.
tDoteck 3G8 series transmitter equipped with auto-cable equalization circuit, and cable driver circuit available at receiver.
tDoteck 3G8 series, both at the transmitter and receiver, signal jitter elimination circuit available, to ensure high quality signal transmission over long distance fiber cable.
tDoteck 3G8 series uses 5V power supply system, low power consumption.
