help: getting internet in my flat

[souljacker]

It is possible to bend fibre such that detectable light from the stream emerges. This can be improved by a small scratch linear to the fibre but you risk detection because this increases the loss from the cable. Whether this works outside the lab is highly classified. For which reason we lay people (sic) believe that it is possible and has been done.

I've been to a training demo that showed fibre media convertors with hardcore encryption that is for defending against this sort of thing. They cost a fortune, but the sniffers that you describe above cost hundreds of thousands of pounds.

Very popular in the spying communities, as you can imagine.
