Extreme switches 200 series SFP uplinks are not working

[Brandon_Cuellar]

Customer has a 220 series 12 port and 48 port and is trying to connect the 2 via SFP ports on 1/0/13 on the 12, and 1/0/49 on the 48, but still have a link state down. This is a flat network, only the default VLAN is there.
SFP modules are compatible (10301; 10GBase-SR). Can verify the SFPs are there on both switches.
Firmware is up to date to 1.2.3.5.
There is no serviceport address, but a network address is configured. Both ports are configured as a trunk with the allowed vlan 1. I tried setting the ports to 10G full-duplex, now currently have the speed set to auto with auto-negotiation on both ports. Also went ahead with the shut/ no shut on ports and still cannot get anything.

Looking at the case notes, it looks like the fiber is OM1 and is over the max distance for 10G

Well, I did it mostly using OM3.

I've ran 10G links much over 33M distance many times. Is this 10301 SFPs limitation ?

I believe I found out the issue. The current fiber lines do not work with the 10GBase-SR SFP+. They need to swap out the SFPs with 1G SFPs since the fiber they have from building to building is well over 33M to support the 10G SFPs.
