Introduction
tDoteck 3G series digital video fiber optic transmission system can transmit one 2970Mbps 3G-SDI super high definition digital video, or 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 SMPTE424M, SMPTE292M, SMPTE259M, SMPTE297M, SMPTE305M, SMPTE310M.
tDue to the advanced digital fiber optic transmission and SDI 3Gbps technology , almost you need not make any adjustments, simple to set up, easy to operate, so very suitable application in TV station, digital TV, IPTV, mobile TV, mobile phone TV and other new media fields.
tDoteck 3G series transmitter provides one 3G/HD/SD-SDI input, and one loop-through for local monitoring. The receiver outputs 2-way parallel 3G/HD/SD-SDI digital video.
tDoteck 3G series transmitter equipped with auto-cable equalization circuit, and cable driver circuit available at receiver.
tDoteck 3G series, both at the transmitter and receiver, signal jitter elimination circuit available, to ensure high quality signal transmission over long distance fiber cable.
tDoteck 3G series uses 3.3V power supply system, low power consumption.
