Kramer 673R/T
4-Channel 3G HD-SDI over Single Fiber Optic Transmitter & Receiver

OUR PART #  673R/T


The 673T and 673R are a high-performance fiber optic transmitter and receiver for video signals up to 3G HD-SDI and dual link HD-SDI signals. The 673T converts up to four channels of SDI signals on BNC connectors to an optical signal that is transmitted over a single fiber optic cable. The 673R converts the optical signal back to SDI signals.

Kramer 673R/T Features:

  • Max. Data Rate - Up to 3Gbps for each SDI input.
  • SDI Inputs/Outputs - 4 channels on BNC connectors.
  • HDTV Compatible.
  • System Range - 1000m (more than 3200ft).
  • Fiber Cable - A single multi-mode OM3 fiber optic cable with SC connectors.
  • Multi-Standard Operation - SDI (SMPTE 259M), HD-SDI (SMPTE 292M) and 3GHD-SDI (SMPTE 424M) and dual-link
  • HD-SDI (SMPTE 372M).
  • Reclocking and Equalization per Channel.
  • Fiber Optic, Source & Input Indication LEDs.
  • Compact DigiTOOLS® - 3 units can be rack mounted side-by-side in a 1U rackspace with the optional RK-3T rack adapter.
