I recently asked a question about which type of Fibre optic cable to use for my installation. We have now found a cable type and supplier and I'm about to order the cable (OM3, Tight Buffered, 12 Core), however I have a further question:

We are shortly moving in to a new building (still being constructed) and we are about to get a window in which we will be able to run any cabling that we need.

How should I roughly cut the fibre? Can I just use some heavy shears to cut through the cable? I'm aware that doing so will damage the ends, but will the damage be limited to the ends, or could the cracks/fractures continue up the length of the cable?

p.s. I have already allowed for several metres of extra cable at each end, and I am going to get a specialist in to terminate the fibres.
