AI-generated summary
For £16.13 ex-VAT, this is a sensible “just make it work” jumper lead if you need a short, tidy OS2 LC–LC connection without fuss. The bend-insensitive angle is genuinely useful in the real world: in patch panels, over-rack routing, and cramped comms cupboards, LC tails can get stressed just from how they’re trained. You’ll also be paying for low insertion loss and better consistency on single-mode links, which matters if you’re pushing higher capacity over longer runs where every little bit counts. It’s the kind of cable I’d happily buy in bulk for data centres, ISP POPs, and any UK business with structured cabling that doesn’t want to play guessing games with optics and attenuation.
Who it’s for: anyone deploying single-mode fibre with LC duplex optics (think 10G/25G/100G-style gear) and wanting a reliable patch cord for patching between switches/ONTs/ODFs and the rest of the network. Who should think twice: if you’re trying to standardise on a specific duplex/connector type at scale, make sure your transceivers and patching plan are definitely LC duplex OS2 (not multimode, not APC/UPC mismatch, not simplex). Also, if you’re regularly needing longer lengths or you’re in a very messy install, you may end up “buying twice” because patch leads are cheap compared to getting reworked routing right—so consider whether a proper structured solution would save time later.
