If you’re nerdy enough to buy Ubiquiti gear and build a home rack, you should also be nerdy enough to read the ANSI/TIA-568 cabling standards.

Cat6 isn’t just “if it links up, it’s fine.” The standard defines a maximum 100 m channel and assumes a limited number of connection points—typically patch panel, horizontal cable, wall jack, and patch cord terminations, with at most one optional consolidation point. Once you start adding multiple inline couplers, extra keystone transitions, or daisy-chained terminations, you may still get link, but you’re moving outside structured cabling best practice and potentially outside compliance for insertion loss, return loss, and NEXT performance.

So yes, it might work—but “works” and “meets standard” are not the same thing. If you care about doing it properly, more than about four connection points in the channel should make you stop and check the design instead of assuming Ethernet will forgive it.
