It&#x27;s definitely not something to trust in, but intercepting (at a layer 1 level) a PTP 80 GHz link is actually harder than tapping fiber. You&#x27;d have to have Rx equipment either directly in the path or directly behind both ends of the radio link.<p>As compared to the effort required to cut an aerial or underground singlemode cable and fusion splice in place a passive prism split tap (basically the same thing as inserting a split in a GPON FTTH network). A practiced outside plant fiber crew of 2 persons and a bucket truck could do this with less than 5 minutes of downtime on a router-to-router optical interface, short enough time to clear any NMS alerts and prevent a repair team truck roll. Assuming we&#x27;re talking about only two strands.<p>Either way actual security is accomplished through standard based crypto, not obfuscation or preventing people from messing with the layer-1.
