I am trying to connect (2) USW-24-POE switches together with single mode SFP fiber with a length of about 350’. The link will not come up. We have tried multiple fiber strands, all of which test good. If I move the SFP module to another UISP Edge Switch on one end, the link will come up. Also, The link will come up if I connect the 2 USW switches on a short run.
We have traded with known working SFP modules with no success.
SFP module is a UACC-OM-SM-1G-S-2
Is there a distance limitation I’m not aware of with the USW line of switches? Any other suggestions?
Thanks in advance…
