IVY BELLS (USN is / was an ALL-CAPS org, right?) was a copper era project, and it did use EMI tapping (TEMPEST) to get to the traffic without tampering with the cable.
Fiber can be tapped, too, though it's not as easy as EMI. Heck, it can even be potentially 'pre-tapped' prior to deployment.
Having gotten that cleared, I'd argue that if you're on speaking terms with the cable operator, it is much easier to use a full-spectrum monitor port on the WDM system.
The issue is that the cable operator may be on speaking terms with reporters at the Guardian. ----------------------------------------------------------------------- Roland Dobbins <rdobbins@arbor.net> // <http://www.arbornetworks.com> Luck is the residue of opportunity and design. -- John Milton
