      I'm under the impression that the calculator takes into account the speed anticipated when the cabinet is filled up, but crosstalk does have a massive influence over the maximum obtainable speed.

      I'm tempted to go and glue the locks on my fibre cabinet to prevent any more FTTC installations

      I dont understand all this talk of FTTC being so effected by crosstalk, on the BTO site under the general info about the upgrade to a fiber network they state that 1 of the benefits of using fiber is that it is apparently immune to crosstalk, or is crosstalk from the cables and crosstalk at the DSLAM connections 2 different issues


      Compared to copper, fibre is:
      inherently more reliable
      longer lasting
      able to carry more data over long distances
      resistant to electromagnetic interference
      immune to corrosion
      secure and immune to crosstalk
      easier to handle and install.

      After persistant pestering of the Fibre team I have been assured my connection will upgrade during the early hours of the night to Pro. As we've seen these posts before, i'm taking it with a pinch of salt but there is an order showing in My Sky.

      Fibre Optic cabling allows the transmissions of millions of packets of data. When I worked in the telecoms industry the techies used to say it was potentially limitless and its the controlling gear at either end that interprets the light transmission that limits the capacity.

      I agree, I think it is the size of the 'pipe' they install from the cab to the exchange that is the limiting factor. It is possible BTO completely underestimated the demand and did not beef up the connection enough.

      The fibre cables from the dslam (street cab)to the exchange is immune to crosstalk but the copper leg from your house the dslam is
      I doubt if a few extra metres of copper is going to make much difference.

      Re: Sky Fibre Unlimited Pro Rumour

      Before SFU was launched someone else posed this question and I didn't understand the issues. At the time I thought that they were suggesting Sky's traffic would share the same fibre optics to the exchange so said it shouldn't happen.

      However this isn't the problem. As Andrew has pointed out, the issue is with the copper cables.

      The higher frequency of FTTC on the copper wiring appears to be causing interference with other connections. I believe that this is why the connection estimates have so far proved to be significantly lower than what people have been getting. I also explains why, as more people become connected on the FTTC cabinets, that some people are finding that their maximum potential speeds are dropping.

      To the best of my knowledge, the Fibre connection from the FTTC cabinet to the Sky kit is not subject to this interference.
