Product Overview

AI-generated summary

For £84.67 ex-VAT, this StarTech 25G SFP28 SR optical is a pretty sensible buy **if** you’re dropping 25Gbps over short-ish multimode runs and you want to keep the spend under control. The headline for day-to-day use is reliability: SR with DOM/DDM is exactly what most switch folks look for when they want basic optical health monitoring without adding extra tooling. The 100m class is also the sweet spot for typical rack-to-nearby MDF/IDF cabling in offices and data rooms, where multimode usually makes financial sense versus swapping to long-reach single-mode optics.

Who should buy: **IT teams standardising 25G optics across a mix of switches**, especially where you have multimode fibre already in place, and you care about visibility (DOM/DDM) for troubleshooting and uptime. Who should *not* buy: anyone assuming “mmf = always fine”—if you’re pushing further than your plant supports, or you’re on single-mode fibre, this will be the wrong optic and you’ll waste time/returns. Also, sanity-check that your exact switch model is happy with third-party SFP28 optics (most are, but it’s not universal). If compatibility lines up, it’s solid value; if not, you’ll be paying £84.67 to discover a firmware/compatibility mismatch.
