HD Video + RS232 fiber system
Lightem Systems LHD series digital video fiber optic transmission system transmits 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 reverse control data RS232 through one single mode fiber or multimode fiber with the standards of SMPTE259M, SMPTE297M, SMPTE310M, SMPTE305M (SDTI). Lightem Systems HD series transmitter provides one HD-SDI input, and one loop-through for local monitoring. The receiver outputs 2-way parallel HD-SDI digital video.
Lightem Systems HD series transmitter equipped with auto-cable equalization circuit, and cable driver circuit available at receiver.
Thanks for the auto-cable equalization, cable driver circuit and signal jitter elimination circuit, high quality signal transmission over long distance fiber cable is realised.
- HD-SDI/SDI/ASI signal auto recognition
- Compliant with the standards of SMPTE292M, SMPTE259M, SMPTE297M, SMPTE310M, SMPTE305M (SDTI), SMPTE344M
- Compliant with the standard of DVB-ASI(EN50083-9)
- Auto adaption to the speed of HDSDI/SDI 143M,177M,270M,360M,540M,1483.5M,1485Mbps, or DVB-ASI
- A variety of installation options: 16-slot rack, particularly suitable for large volume optical transmission platform construction, and also available for 4-slot rack, 2-slot rack and single-slot rack, fixed 1RU 19-inch enclosure box.
