Belden CA21103020 Cat6 Patch Cable Cmr 20 Ft

Product Description

The Belden CA21103020 is a Cat6 patch cable rated for CMR (Communications Multipurpose Cable, Riser) environments, designed for structured cabling installations in commercial and light industrial buildings. This 20-foot orange patchcord supports 10-Gigabit Ethernet applications using the B10GX design standard, making it suitable for high-speed network backbone and horizontal runs. The orange jacket aids in visual identification of network segments during installation and troubleshooting. Licensed network technicians and low-voltage cabling contractors are the typical installers for this type of structured cabling component.

This patch cable is used in riser-rated cabling installations where cables must pass between floors or through vertical shafts. The CMR rating meets fire propagation requirements for riser pathways without requiring plenum-rated materials. Typical applications include data center patch panels, network closets, and server room equipment connections in commercial office buildings, schools, and healthcare facilities. The 20-foot length suits longer cross-connect runs between rack equipment and patch panels.

Installation Notes

Installation should be performed by a licensed low-voltage cabling contractor or qualified network technician in accordance with TIA-568 and applicable local building codes. De-energize connected equipment before disturbing patch panel connections where possible. Avoid sharp bends below the cable minimum bend radius to preserve signal integrity. CMR-rated cables must not be substituted for CMP plenum-rated cables in air-handling spaces.
