Product Overview

AI-generated summary

For £19.84 ex‑VAT for a 5m 10GbE copper DAC, this is the kind of no-drama, sensible part you buy when you already know the link distance and you don’t want to pay for optics. Passive 10GbE DACs are ideal for short, predictable runs (same rack, adjacent switches/servers) because they’re simple, low power, and usually just work with mainstream SFP+ ports—no fussing with transceivers, patch leads, or alignment. If you’ve got Juniper-compatible SFP+ ports and you’re trying to keep costs down on internal connectivity, it’s a solid value.

Why you might *not* buy it: DAC compatibility can be a bit finicky across vendors/models and firmware (even when labels say “compatible”), and some environments are pickier than others about what they accept. Also, 5m is great for rack-to-rack, but if you’re ever tempted to stretch beyond that, you’ll end up troubleshooting link stability instead of doing your real job. In short: buy it if this is for short-range, like-for-like SFP+ deployments and you’re comfortable testing if your specific switch model is unusually strict; skip it if you need maximum “it will definitely work everywhere” confidence or your run distance/layout isn’t truly within spec.
