Main features
  • Low second and third order distortion, which provide a high output voltage (typical values around 120 dBμV)
  • Equipped with two signal inputs, which allow the mixing of the channels of its own headend with channels coming from other sources
  • Equipped with a test output

In some cases, the transmodulation of specific satellite channels into COFDM will probably not be enough; this is why the option is available to add the IF of a satellite polarity to the COFDM signal flow. Furthermore, that signal flow may be transmitted over optical fibre by means of an appropriate low-loss optical transmitter, thus allowing to reach longer distances.

How can I add an IF signal to a DTT-only T.0X processing headend and transmit it through an optical fibre to distant spots?
