Introduction
tDoteck HD2 series digital video fiber optic transmission system can transmit 2 HD-SDI(1483.5M/1485Mbps)high definition digital video, or 2 SD-SDI(143M/177M/270M/360M/540Mbps)standard definition digital video or 2 DVB-ASI stream through one single mode fiber or multimode fiber with the standards of SMPTE292M,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 HD2 series transmitter provides 2 HD-SDI input, and 2 loop-through for local monitoring. The receiver outputs 4-way parallel HD-SDI digital video.
tDoteck HD2 series transmitter equipped with auto-cable equalization circuit, and cable driver circuit available at receiver.
tDoteck HD2 series, both at the transmitter and receiver, signal jitter elimination circuit available, to ensure high quality signal transmission over long distance fiber cable.
tDoteck HD2 series uses 3.3V power supply system, low power consumption.
