£73.67 inc. VAT
AI-generated summary
At £61.48 ex‑VAT, this StarTech 1GbE SFP is the sort of “get it working without drama” optic you buy when you already know the link budget is covered. The 70km single‑mode/LC angle makes it a decent fit for longer rural/remote runs or site-to-site fibre where you don’t want to pay big-brand pricing. The fact it’s MSA-style and includes DDM is genuinely useful in day-to-day operations—you can actually monitor optics health rather than guessing when links get flaky.
That said, I’d only buy it if your network gear is compatible with that specific vendor/optics class and you’ve confirmed the transceiver tolerance matches your switch/router model. These mid-priced SFPs can be totally fine, but if you’re in a strict environment (particular optics expectations, zero-tolerance change control, or higher-risk links), I’d rather validate with a quick compatibility check or test unit first. For most standard UK SME/enterprise deployments running single‑mode at distance, it’s good value; if you’re expecting “drop-in perfection” across every switch without checking, that’s where you can get burned.
