Introduction
tDoteck HDX2 series HD-SDI+RS232/422/485 HD 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 bidirectional control data RS232/422/485 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 HDX2 series transmitter provides one HD-SDI input, and one loop-through for local monitoring. The receiver output 2-channel parallel HD-SDI digital video.
tDoteck HDX2 series transmitter equipped with auto-cable equalization circuit, and cable driver circuit available at receiver.
tDoteck HDX2 series, both at the transmitter and receiver, signal jitter elimination circuit available, to ensure high quality signal transmission over long distance fiber cable.
tDoteck HDX2 series uses 3.3V power supply system, low power consumption.
