I am talinkg about wiretapping. In most situations there is no reason for it but the spiffy little device negates the security of fiber lines. In most instances fiber can be approached just like any other medium.

The way to cut into a line that is outlined here is the least expensive option. If the line isn't being multiplexed then it can be done for under $50 if you can borrow someone's cutter.

Apparently petemcevoy does not know what network sniffing is in the software sense.

if someone tries to connect to the ring, they need specialist equipment and the ring would be disturbed - it should not go unnoticed.
This is what my device tries to limit-connection disruption, while still tapping the line.
