AI-generated summary
For £28.14 ex-VAT for a 5m OM4 LC–LC fibre jumper, this is the kind of “just works” cable I’d recommend when you’re building or patching an active setup and you want to avoid faffing about with polarity. The toolless polarity switching is genuinely useful in the real world: it saves time (and mistakes) when you’re plugging into gear that expects a specific Tx/Rx orientation, especially if you’re doing moves/adds/changes in a comms room. Low insertion loss is what you want for short runs like this—practically, it keeps performance consistent rather than relying on “it’ll probably be fine”.
I’d buy this for: datacentre patch panels, switches/routers with LC ports where you’re standardising on OM4, and anyone who regularly re-patches fibre and wants faster, safer troubleshooting. I wouldn’t bother if you already have a mature process where polarity is managed elsewhere (or you only ever run fixed links you never touch), because the extra mechanism you’re paying for won’t give you much day-to-day benefit. Also, double-check that OM4 is actually what your optics are expecting—£28 is cheap insurance, but not if you’re mismatched on the network side.
