Regular price $899.00



  • 1 Ch 3G/HD-SDI video (Forward: from Transmitter to Receiver) & 1 Ch RS 485 data (Reverse: from Receiver to Transmitter) over Single-mode Fiber
  • Handles all pathological patterns
  • Automatic cable equalization to ensure signal integrity
  • Support signal type: 270Mbit/s to 3Gbit/s according to SMPTE 424M, SMPTE 292M and SMPTE 259M standards
