How far do you need to move it?, would it need to be lengthened ?.
Is it in conduit now or in the ground.
Need more info so people can help.Me being a DIY person if it could be moved with out having a longer piece of cable installed I would just move it and say nothing
If it will be too long when it's moved just make a coil of it before it's buried.
If it's anything like the pieces of fibre off-cuts I was given to look at when they installed it in our village it's very very tough, the fibre's are well protected.
