Communications cable
A category label and a jacket fire marking answer different questions. Verify the maker’s product number, pairs, AWG and shield configuration separately from the jacket legend, UL category and any lot-specific field test.
Submit cable detailsMake the next decision with evidence
Do not sell a CM-marked box as CMR or CMP, or describe an untested remainder as field-certified. The exact product sheet and markings establish a checkable starting point.
A manufacturer example describes nominal product performance; stored or opened stock needs its own length, handling and condition disclosure.
Focused guides
Verify a cable category before listing
Keep Cat 5e/6/6A identity, pair count, conductor metal, shielding and any field-test evidence separate on a surplus communications-cable lot.
Technical guideCM, CMR and CMP are not Cat ratings
Identify communications-cable jacket/fire-classification markings from the actual legend and matched maker sheet; avoid calling CM stock plenum-rated.
