How much bandwidth is shared on FTTC?

Hi there,

I was just wondering if anybody knew how much bandwidth would be shared between how many subscribers in a typical OpenReach FTTC cabinet? i.e. would you have a 1Gb/s line between 100 houses or 50?

We are on a FTTH connection which has a brilliant 1Gb/s link back to the central router, but only a 100Mb/s line feeding that, shared between around 60 properties, so it can theoretically drop below 2Mb/s if all the houses are using the connection at the same time!
 
It's become a little more difficult to answer that since Capacity Based Charging came in some years back because now "contention ratios" no longer exist on BT's platform, at least not in the way it use to.

Every area tends to be different but most ISPs will adapt to local demand as capacity fills up, although different providers may draw the line at different points. One issue with this is that it can sometimes take a while for new capacity to come online, especially if a new physical feed is required, although once again this varies.

You also have to consider that same street cabinets are only setup to handle a tiny number of premises, while others could serve significantly more. As a result I'm not really sure what a typical cabinet would be like in this market, especially since BT doesn’t like to talk or share much info. about its cabinet locations or sizes etc.
 
Between cabinet and exchange Openreach guarantee 20Mb per 40Mb customer and 30Mb per 80Mb customer, and add additional capacity between cabinet and exchange in 1Gb increments as required.
