NVIDIA - QSFP28 transceiver module - 100GBase-X - MPO multi-mode - up to 100 m - 850 nm

Product Overview

AI-generated summary

If you need 100G over short, multi‑mode fibre, this QSFP28 transceiver is a fairly sensible buy at £163.87 ex‑VAT. The headline reason is straightforward: it saves you from paying a “single supplier premium” when you’re plugging into an existing QSFP28 switch/router platform and you’re confident your optics match the link budget. In day‑to‑day operations, the biggest win with these modules is reliability—assuming you buy the right type for your optics (multi‑mode, 850nm) and you’re within the stated reach for your actual fibre plant.

That said, I’d be cautious about ordering these based on “looks right” fibre assumptions. Multi‑mode at 850nm and ~100m can be very sensitive to patch panels, fibre quality (OM3 vs OM4), number of connections, and cleanliness—things that absolutely matter in real UK data rooms. If you don’t already know your exact fibre type and end‑to‑end attenuation, you can end up with flaky links or costly rework; in that case, it’s often better value to step up to the module type that matches your measured cabling, even if it costs a bit more.

**Who should buy:** teams standardising 100G QSFP28 in a controlled, known multi‑mode environment (data centres, modern sites with good OM3/OM4 cabling) and wanting solid cost/performance. **Who shouldn’t:** anyone unsure about their fibre type or reach, or anyone needing longer runs—because the wrong optics choice will waste time and make troubleshooting painful.
