I've read a lot of comments about fibre optic broadband being more stable than ADSL. Most of these seem to be based on the fact that glass tubing eliminates electrical interference. However, as the signal will have to travel along copper wiring from the cabinet to my house, I was wondering whether FTTC really would prove more stable than ADSL.
At the moment, my ADSL connection drops once-to-twice per day. Not the end of the world by any means, but can be problematic if a credit card payment is processing, or frustrating if I'm watching a movie.
I have to use G.DMT modulation - ADSL2 is highly unstable - and the speed is around 3.6 Mbps. The FTTC speed I'm predicted is 15 Mbps (I know this is also Openreach's minimum sync speed for fibre optic broadband). The main reasons for the relatively slow speeds are likely to be a combination of my distance from the cabinet and the fact my house is connected by overhead, rather than underground, cabling. The speed isn't a massive concern, though - my main priority is a more stable connection.
There is a little noise on my line. This is audible via a BT quiet line test, and my upstream SNR margin is typically around 10 dB.
The most likely culprit is one - or all - of five extensions. I could rewire these, but there would be a cost both in terms of time and money, with no guarantee that my connection would become any more stable. By contract, FTTC would only be a few quid extra per month, so this seems like the more attractive option.
Do you think upgrading to FTTC would result in a more stable connection? Have people here found this to be the case after switching?
