For £48.10 ex-VAT for a 5m SFP+ direct-attach (DAC) twinax, this AddOn cable is the kind of “get it working now” option I’d consider for straightforward, short-reach links—think stacking/switch-to-switch runs in a data cabinet where you know the ports and optics tolerance are a good match. If you’re replacing a dead/failed DAC and your Force10 equipment is behaving with other vendor DACs, it can be very good value versus branded optics.
That said, I wouldn’t treat an “Force10 compatible” DAC as automatically interchangeable across all setups. DACs are usually picky about both link training and EEPROM compatibility, and when they don’t play nicely you can end up with flapping links, speed negotiation issues, or it simply not being recognised. So: buy it if you’re confident you’re matching the right vendor/platform generation and you can quickly test it; avoid it if you’re building something critical where you can’t afford “sometimes it works” behaviour. If you tell me the exact switch model and what you’re connecting to, I can give a much firmer thumbs-up or thumbs-down.
