Questions about CATV Signals

I am catv operator. I run from analog signal (48Mhz to 860Mhz) 105 channels. we convert RF signal through RF to Optical Converter (1310NM single mode) ,use this

on OFC and on exit use optical to RF converter (node) and use it on TV set.

Now we are trying to use 1310NM optical signal on stm(Synchronous Transport Module level) and STM receiving this signal.

And when are taking out signal from the other end of STM optic and converting

This into RF signal using optical to RF converter(node) but there is no picture

on Tv set.

Queries

1) how much bandwidth is required to run these 105 analog channels.

2) How to use existing signal through STM.
