01 User manual
The optical signal level at the input of the multiswitch SCF316/8 must lie between 0dBm e -14dBm.
Optical signals higher than 0dBm can irreversibly damage the SCF316/8 multiswitch.
In PON with less than 4 optical points add a proper optical attenuator.

Line
The TXWBT headend converts and transmits over a single-mode optical fibre the terrestrial
signals (DTT, FM, DAB) processed by the programmable terrestrial headend DSP20 and
all the transponders of a satellite received from a Wide Band LNB. The optical signals are
received by the optical multiswitch of the SCF316 series and converted into RF ready for a
single or multi-dwelling coaxial distribution. Each SCF316 series output provides terrestrial
and satellite signals supporting the legacy or SCR/dCSS standards (AUTO-SWITCH).
