I’ve got several CRS305-1G-4S+ in service. Never had a problem with any of them. It will definitely run off of the Cyber Power 48v UPS.
I have no idea on the max wattage for an SFP+. We could infer 2W per SFP+ based on this spec, but can’t say for sure whether a single port could exceed that. I’d test it for you, but I don’t think I have any transceivers that use that much juice.

See the pics I posted above. Just need to extend the SFP+ cage out of a Siklu radio. The alternative is to add another little switch but that adds complexity to what is a simple design. PON hanging off a Siklu for a small apartment building. Only thing active is the Siklu and the "SFP". One cyber power 48V battery backup to power the silku. If you add a switch, how are you powering it, where is it mounted, etc. On the note of adding a switch. Has anyone used the CRS305-1G-4S+IN? Anyone have a contact at Mikrotiik who could find out the SFP+ port's power budget?

The description on the linked item says it’s so you can put your electronics into immersed liquid cooling without exposing your optics to the liquid. Pretty esoteric stuff. Not understanding the use case, but assuming there’s a reason you can’t extend the fiber a few feet with a jumper and mating sleeve, then how about use a DAC to reach another switch?

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 -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- Zach Underwood (RHCE,RHCSA,RHCT,UACA) My website <http://zachunderwood.me> advance-networking.com <http://advance-networking.com> -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- Carl Peterson PORT NETWORKS 401 E Pratt St, Ste 2553 Baltimore, MD 21202 (410) 637-3707
