Cisco Access Points - Cabling issues

Hi,

I just wondering if there was any documentation that shows what the Maximum cable length can be for Cisco to support their Access Points

Thanks

E.g. : https://www.cisco.com/c/en/us/products/collateral/wireless/catalyst-9100ax-access-points/deployment-guide-c07-743490.html#:~:text=Note%3A%20The%20Ethernet%20cable%20recommended,328%20feet%20(100%20meters).
>...The Ethernet cable recommended is CAT-6 with a maximum distance of 328 feet (100 meters). Power required at the Power Source Equipment (PSE) will depend on the cable length and other environmental issues.

Thank you, where could i find the documentation that would show that against that particular AP, I've searched everywhere, could do with it as evidence to a discussion I am having.

The standard maximum distance for GigabitEthernet and PoE is 100 meters.

Cable length is a function of the ETHERNET and POE standards not the AP specifications!

Refer to the relevant IEEE 802.3 standards documents for those cable length specifications.

Remember longer cable = greater power loss for POE.
