Plenum-rated Cat 5e cables meet CMP requirements for use in plenum spaces, such as air-handling areas above suspended ceilings, where cable materials must limit smoke and flame spread. Riser-rated cables meet CMR requirements for vertical runs between floors, but they may not be permitted in plenum spaces, so follow local codes and project specifications when selecting cable.

Choose unshielded plenum rated Cat 5e cables for many in-wall networking installations where the cable will not run near substantial electrical interference; choose shielded cable when the project calls for added protection from electromagnetic interference and includes compatible shielded connectors, patch panels, and grounding practices. Also confirm that the cable’s plenum rating matches the air-handling space, and review the installation requirements for conductor type, cable layout, and termination.

Plenum-rated Cat 5e cables are intended for in-wall installation in plenum and riser spaces where the cable jacket rating must meet applicable building and electrical codes. Confirm the project specifications and local requirements before installation, and follow the cable manufacturer’s guidance for routing, termination, and separation.

Compare the CMP or plenum rating and listing, Cat 5e performance, bandwidth, conductor size and material, solid four-pair construction, and cable length. Also consider jacket color, ease of stripping, and pull-friendly packaging features that can help simplify identification and installation.
