I spoke with someone recently. He is swapping out a fiber based Crestron DM system with a new AVPro Edge system. Originally the system used a single strand of fiber. The new system will require 2. Luckily a cable with 4 was pulled.
Bringing this up to illustrate how conduit is always better than trying to guess which cable to use for future proofing.
