You know, I’m fuzzy on why the cage extender has a 2.5W limit. There are no components visible on the PCB.
3.5W at 3.3V should be 1.2 amp. The traces should carry several amps. The 10cm cable isn’t going to have an issue with 3.5W Who said it had a 2.5W limit?

The existing device supports the power but the only SFP+ cage extender I can find is only rated at 2.5W. Can you passively just extend the cage pins or is this something that requires electronics? Anyone know of a higher power SFP extension cable? https://www.sfpcables.com/sfp-to-sfp-cage-with-3m-flat-cable-in-nylon-jacket-20cm-and-55cm-length-3256-5454 -- Carl Peterson PORT NETWORKS 401 E Pratt St, Ste 2553 Baltimore, MD 21202 (410) 637-3707
