HD-SDI fiber system

Lightem Systems LHDVD series digital video fiber optic transmission system transmits X HD-SDI(1483.5M/1485Mbps)high definition digital video, or X SD-SDI(143M/177M/270M/360M/540Mbps)standard definition digital video or one DVB-ASI stream tdrough one single mode fiber or multimode fiber witd tde standards of SMPTE292M, SMPTE259M, SMPTE297M, SMPTE310M, SMPTE305M (SDTI).
Lightem Systems LHDVD series transmitter provides X HD-SDI input, and X loop-tdrough for local monitoring. The receiver outputs X-way parallel HD-SDI digital video. Thanks for tde 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, need not select by hand
  • Compliant witd tde standards of SMPTE292M, SMPTE259M, SMPTE297M, SMPTE310M, SMPTE305M (SDTI), SMPTE344M
  • Compliant witd tde standard of DVB-ASI(EN50083-9)
  • Auto adaption to tde speed of HD-SDI/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.
