Dave,
We do the cable qualifications (Use a Fluke Networks cable qualifier and provide the results to the NOC if asked...everything is qualified to 1000 Base-T).
I agree that patch panels should be labeled but 90% of the time, they don't seem to be or are labeled haphazardly with labels that don't really fit.
Why does "networking done right" use patch panels?
What makes a punch down, that relies one to strip back a cable, route the ends to the IDC punchdown point and strain relieve that cable, without violating any bend-radius rules, and have many unrelated pairs in close proximity have over a properly terminated RJ45M where the jacket remains in tact all of the way into the connector? The patch bay becomes mostly another point of failure.
I agree that patch cables can be cheap and reliable...though there is always a bad apple in there too. We qualify everything...every once in a while, there is a dud.
As for loose cables of indeterminate length...who said anything about that? I don't advocate putting it in all crazy. Route them through the rack properly send them out through a suitable panel (can be one like the Middle Atlantic Products BR1 or even a proper patch cable wire trough. Nothing says it can't be neat.
Even in a large plex, it just isn't that big a deal to dress up the two cables per theatre into a TMS system. What we normally specify is that if the client wants to install their own cables ahead of us (we prefer it actually) then they can terminate into biscuits (surface mount boxes) at each theatre and just have the TMS drop down with a minimum length and marked. Invariably, if there is a problem, it is where they punched down into biscuits at the theatre end. There are times I'd rather just put both ends on since when we pull our own Ethernet...it just works.
I'm just not a fan of unnecessary patch bays that will never actually be patched. They seem like a waste of time, money and can lead to unnecessary failures.
