Are you sure its a fibre MM?
Its more common to install a 2, 3, 5, 10 or 20 twisted pair cable to a home / business for the phones and a coaxial cable for the TV and Broadband as a fibre feed would need a business rack installed which contains £70K + worth of kit to receive the optic feed and convert it to RF for the TV & broadband and another set of kit for the phone lines which is why fibre feeds tend to only be provided to large businesses or communities in rural areas.
The Nynex bosses used to say theres no profit in tv only phones, however now a days the biggest profit is in data transfer and broadband.
The adverts from earlier this year made people think they had a fibre installed to their house which didn't help the service engineers like myself. The truth of the matter was when I joined the original company in my area which was Nynex back in '92 the core network even then was built using fibres from the headend to the hub sites then onto what we call a mux (local exchange) from there the laser light was converted to RF and sent down very thick coaxial cables to the hundreds of small cabs then down smaller RG6 or RG11 coaxial cables to feed customers.
