The television program that I saw on laying and joining underwater cabling made it look to be a relatively simple task in deep water so on the beach it must be a fairly routine procedure. There are a lot of old disused copper cables lying around West Country beaches so maybe it was one of those if no one was doing anything about it.

Really? I can't believe anyone leaves copper cable where it is unless it's very well protected.

Most data cables contain little copper and are not very attractive to thieves.
Power cables are much more likely to be a target.

The old fashioned telegraph cables contain relatively small copper cores together with a lot of near valueless insulation and armouring.
There are many abandoned cables of this type.

Newer fibre optic cables for LOCAL circuits contain no copper.

Long distance fibre optic cables DO contain a copper core, this carries electric power for the repeaters or amplifiers that are incorporated into the cable. Several thousand volts at a few amps is commonplace.

Abandoned telegraph cables if exposed on beaches are sometimes removed, for public safety reasons. Bare feet on the beach or when paddling in shallow water, and rusty bits of broken armouring wire are an unpleasant combination.

Modern data cables, if exposed are usually either re-buried, or enclosed in iron pipes. (these consist of two semi-circular channels that fit together around the cable. This protects against wear or accidental damage, but gives little protection against deliberate sabotage)

Abandoned power cables are usually recovered for the scrap value.
