Cisco - SFP+ transceiver module - 10GbE - 10GBase-SR - LC/PC multi-mode - up to 400 m - 850 nm

Product Overview

AI-generated summary

If you’re buying this Cisco-branded SFP+ (10GbE, SR, multi‑mode), you’re basically paying for a safe, “just works” optics option—especially if your switches are already Cisco and you don’t want to spend time wrestling with compatibility or firmware quirks. In a UK data room / comms room environment where you’ve got short-ish runs and multimode cabling, the SR transceiver is the sensible choice: low hassle, widely supported, and you can usually drop it into the switch and get on with your day. At £275.76 ex‑VAT, it’s not cheap, but Cisco optics can be worth it when uptime and predictability matter more than squeezing every penny.

That said, I’d only recommend it if you’ve confirmed you’re using the right fibre type (multimode) and the distance fits your design. If your cabling is single‑mode or you’re pushing longer distances, you’ll be wasting money. Also, if you’re cost‑optimising and you don’t need Cisco part numbers for vendor support, you may find third‑party SFP+ modules that work just as well—though with Cisco you still have to manage the “will it be accepted by the platform” risk. If you tell me your switch model and the run length/fibre type, I can tell you whether this is a “fair price for peace of mind” or “overpaying for a problem you don’t need.”
