Belden Inc. 2138A 0101000 Cat5e Shielded Cable Cmr Cmx 1000ft

Product Description

The BELDEN INC. 2138A 0101000 is a Cat5e 4-pair foil-shielded network cable supplied on a 1000-foot reel in black. It carries CMR (Communications Multipurpose Cable, Riser) and CMX (Communications Multipurpose Cable, General Use) flame ratings, making it suitable for in-wall and riser installations where code compliance is required. The foil shield provides baseline protection against electromagnetic interference (EMI), supporting stable data transmission across structured cabling runs. Network installers and low-voltage electricians specify this cable for commercial and residential data infrastructure work.

This cable is used in general-purpose Cat5e structured cabling installations, including horizontal runs, riser pathways, and similar low-voltage wiring applications. The 1000-foot reel format suits new construction and retrofit projects where longer continuous runs are pulled through conduit or open framing. CMR-rated cable is commonly required in riser applications per applicable building and fire codes, while CMX rating supports general-use scenarios.

Key Features

• Cat5e 4-pair construction supports standard Ethernet and data networking applications
• Foil shield provides EMI protection for cleaner signal transmission
• CMR and CMX dual flame ratings for riser and general-use installation environments
• 1000-foot reel packaging reduces splices on longer pull runs
• Black jacket for easy identification and routing in mixed-cable environments

Compatibility

Designed as a general-purpose Cat5e replacement or new-installation cable compatible with standard 8P8C (RJ45) terminations and Cat5e patch panels, keystones, and structured cabling components.

Installation Notes

Installation should be performed by a licensed low-voltage technician or electrician in accordance with applicable NEC Article 800 requirements for communications cables. Verify the required cable rating (CMR vs. CMX) with local code authority before routing through riser spaces or plenum areas. Avoid sharp bends below the cable minimum bend radius and do not exceed the rated pulling tension during installation. Terminate per TIA-568 wiring standards using appropriate punch-down or crimp tooling.
