I have FTTH (in West Cornwall) which is provided via an overhead cable from a pole in the road at the end of my drive. As I am a (retired) communications Engineer, I took a great interest in the installation process and the Openreach engineer was kind enough to show me and talk me through it. I therefore know that there is a continuous fibre from a DF in the manhole across the road from the pole to the fibre termination box in my house. The route back to the exchange is "patched" (or whatever the equivalent for fibre is) through other underground DFs.
I wish to change away from BT (almost impossible to talk to, no email, price increased by 25% in less than two years). I therefore spoke to Zen (is there another choice ?).
Everything sounded fine, except the physical changeover. I had assumed that any patching to a different provider would be done at the exchange, but the Zen salesman said it would involve a visit to my house and a change to use a different "tube" (not sure the correct word) in the "box" at the top of the pole. I am confident this cannot be correct, since it would involve a fibre splice at the top of the pole. I am sure that Openreach do not do splices at the top of poles ! They would not even do one half way up my house wall, it had to be done near the ground. Having watched the process, I can understand why.
Does anyone know how it's done ?
