Fibre-optic

Fibre-optic cables can carry huge amounts of information.

A national fibre-optic network project has started.

By mistake, a grandmother who was gardening damaged the fibre-optic cable that was enabling many internet users to surf the web at high speed.

However, HS2 believes it could sell mobile and broadband providers access to spare capacity in the fibre-optic cabling and telecoms masts being built to support the railway's signalling and telecoms.
