the situation with one of the wireless PtP links at work:
@grawity I chased that attenuation / corrosion problem with Cat 5E lines through a moist area.
Just damp, too. Not even outdoors.
The third replacement for that run got burial-grade gel-filled Cat 5E.
Didn’t bend at all well, but also haven’t had a fourth reoccurrence. (Yet.)
And yeah, the old and green and crusty Cat 3 running parallel to that same run also got re-strung with burial-grade.
