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.

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.
