8943CF 4-Channel Electrical to 4-Channel Fiber-Optic Conversion Module

The 8943CF is a four-channel electrical to optical broadcast quality fiber optic conversion module with reflected electrical outputs. It can accommodate SD/HD/3G-SDI video inputs as well as DVB ASI, unbalanced AES, and Grass Valley® audio TDM interfaces. The optical circuitry is housed in dedicated strap-mount SFP submodule devices mounted on the module circuit board. The SFPs selected set the power and the wavelength for the unit which allows for CWDM operation when combined with the 8939FCA and 8939FCB optical multiplexers. This replaceable optical technology allows for easy upgrade, reconfiguration and servicing.

  • Four-channel SDI/HD/3G-SDI fiber transmitter
  • Also supports DVB ASI, AES, and Grass Valley audio TDM interface
  • Supports up to two SFP devices for up to four fiber optic outputs
  • Reclocking for stable long distance signals
  • Reclock bypass for non-SDI signal types
  • Accommodates lasers with separated wavelengths for CWDM optical multiplexing
  • Single-mode fiber
  • Can be used with the 8943FC receiver and other fiber-ready modules for distances of between 0 and 50 km, depending on the transmitter
  • Meets SMPTE 292M/297M/259M/424M signal specifications
  • Transporting multiple high-definition video feeds over long distances
  • For constructing SD/HD/3G-SDI optical tie-lines
  • Sending multiple optical signals over long distances to fiber-ready synchronizing modules for re-timing
  • To feed the 8939FCA for an extremely compact multiplexed fiber solution
