AI-generated summary
For £15.16 ex‑VAT, this is the kind of low-cost fibre jumper you buy when you just need reliable patching between racks or panels—nothing fancy, no “project” budget surprises. StarTech’s name usually means consistent build quality, and OM5 (plus LC/UPC duplex) is a good choice if your install is aiming at modern multi‑rate multimode gear. The LSZH outer is also a sensible UK office/plant default if you’re routing near people or through cabling pathways where you’d rather not gamble on tougher materials.
That said, you shouldn’t buy it blindly. If your network gear expects OS2/other fibre types, or you’re mixing connector cleanliness/termination standards, this won’t save you—fibre is unforgiving. Also, OM5 has its sweet spot; if you’re using older multimode optics that only really play nicely with legacy OM3/OM4 assumptions, you may be paying for capability you don’t use. Net: buy this if you’re doing straightforward LC/UPC multimode patching within the expected environment and you know you’re matching OM5, duplex LC, and the right transceiver type; skip it if you’re unsure what fibre type the rest of the link is already using.
