Product Overview
AI-generated summary
If you’ve got a Cisco-branded SFP cage on an IE3x00/IE34x0/IE32x0 and you just need a working 1Gb link over standard single‑mode fibre, this StarTech-compatible “GLC-LH-SM” style module is the sort of budget fill-in that can save you serious money versus buying CISCO optics. At **£34.33 ex‑VAT**, the value is strong—assuming you’re not trying to do anything fancy beyond simple point‑to‑point 1GbE. In day-to-day installs, the biggest win is you can keep the switch cost down without the usual “will it negotiate properly?” drama.
That said, I’d be a bit picky about suitability: only buy it if your link is truly matched to the expected fibre type/connector and your distance requirements are within spec, and you’re comfortable that compatibility is “works like Cisco” rather than “Cisco branded warranty comfort.” If this is for a mission-critical circuit (or a customer who will blame optics for any outage), I’d test one first or stick with original Cisco modules. For general UK B2B installs where reliability is important but you’re managing costs responsibly, this is a sensible, no-nonsense option.
