Main features
- Low second and third order distortion, which provide a high output voltage (typical values around 120 dBÎĽV)
- 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.
