FTTC - Does One cabient affect another? ..

Hi guys, Does one FTTC box affect another. If 3 run in a line from the exchange is there an affect on eachother? For example a car wipes one of the 3 out but you are on one that is still in place. Would this have a knock on affect? Please explain this for me if you know. Thanks,

No it doesn't. The fibre runs underground and spurs off to each cabinet; they aren't daisy chained together with one feeding off another.

Didnt know that.

Yeah, a bunch of cabinets connect to one of these which usually lives in a pit underground.

From there these nodes have a fibre run back to a local exchange.

It's like a trunk and branches arrangement, a fibre trunk which branches off into these which in turn branch off to feed individual cabinets and/or FTTP splitters.

The node that feeds my local cabinet is actually about 1.2km away; as you can imagine given the distance it feeds several cabinets in this area of the city, each with its own fibre route and microduct back to that node where all the fibres are, well, aggregated together into a single high count cable back to our local Hunslet exchange.

That said it's still potentially possible for a car running over a cabinet to disrupt other fibers running in the vicinity.
