VIDEO FIBRE OPTIC TRANSMITTER

Features

  • Free standing or mounted in power frame rack.
  • Re clocking to minimize transmitter timing errors.
  • Powered from 5 volts.
  • Automatically adjust to import rate.
  • Conforms to SMPTE standards.
  • Variants available for different fibre connections.
  • 1M width

    The video fibre optic transmitter is a high speed digital fibre optic transmitter which, when used in conjunction with our video fibre optic receiver, will allow the extension of SDI / HDI links up to 4 Km. To achieve maximum distance the transmitter will launch into single mode fibre at a wavelength of 1310nm (the standard for HDI specifies an SC connector and single mode fibre).. Option available to launch at 1550nm.
     Designed to support SMPTE 292M and SMPTE 344M it is optimized for performance at 270Mb/s and 1.485Gb/s. It features DC restoration to compensate for DC content of SMPTE pathological test patterns.
     The fibre optic output wavelength can be 850nm or between 1200 - 1600nm. Copper input is by a standard 75 Ohm BNC connector.
     Front panel status indicators are duplicated on the rear of the module, providing module status independent of unit orientation within rack.
