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.

The reason is that in satellite reception there are multiple working bands (4 voltage combinations - 13 V and 18 V - and tones - 0 KHz and 22 KHz -) that cannot share the same cable. The mentioned bands are: Low Vertical Band (13 V + 0 KHz), High Vertical Band (13 V + 22 KHz), Low Horizontal Band (18 V + 0 KHz), High Horizontal Band (18 V + 22 KHz). In order to select one of them, the appropriate voltage and tone have to be sent to the LNB. In a conventional installation it is up to the satellite receiver to perform this task.
When the installation has a single satellite receiver, it is the receiver itself which requests the desired band at any time and no collisions take place. Conversely, if several receivers are installed and each of them requests a different working band, the LNB will only take the higher voltage and higher tone into account. In other words, if a receiver is sending 18 V + 22 KHz (High Horizontal Band) and another one is sending 13 V + 0 KHz (Low Vertical Band), only the receiver requesting the High Horizontal Band - the highest of the requested bands - will work properly.
One solution would be to install an IF multiband amplifier like Ref. 5363. It would feed the LNB with a fixed voltage and a fixed tone so that multiple receivers could access the appropriate channels for the selected band
