NVIDIA - QSFP28 transceiver module - 100 GigE optical - 100GBase-CWDM4 - LC / LC - up to 2 km - 1310 nm

Product Overview

AI-generated summary

If you’re buying this, you’re basically paying for reliable 100G optics that “just work” in a compatible NVIDIA/partner switching environment, over shortish, mainstream metro-style distances. At £663 ex-VAT, it’s not cheap, but it’s in the right ballpark for a genuine vendor QSFP28 module when you need predictable link stability and proper compatibility. The 2 km limit also means it’s a good fit for data halls, campus buildings, or structured cabling runs where you don’t want to over-spec fibre plant or jump to longer-reach optics.

Who it’s for: UK B2B resellers and IT teams standardising on 100G with CWDM4-style links, and especially those who value “fewer surprises” during installation and swaps. Who should avoid: anyone trying to stretch it beyond its intended reach, or anyone with an optics-compatibility mismatch (older gear, odd vendor optics policies, or networks that have been “patched” with non-matching wavelengths/standards). If you’re not already sure your switch model and firmware support this exact module type and wavelength plan, I’d verify compatibility before ordering—because with optics, the wrong guess turns a £663 item into a return that wastes time and labour.
