ATS Cables CAT5e Plenum (CMP) Cable, 1000FT

ATS Cables offers a 1000ft Cat5e plenum cable with 24 AWG, 4 pairs, and 350 MHz bandwidth. The cable is designed for easy installation in drop ceilings and between floors, with RoHS compliance and ANSI/TIA-EIA 568-C.2 standards alignment. It’s available in blue and supports gigabit Ethernet and PoE applications, making it suitable for office networks and CCTV deployments in plenum spaces.
Buying Guide
When selecting bulk Cat5e plenum cable, consider these factors to balance performance, safety, and cost:
- Jacket rating and location: CMP-rated cables are intended for air-handling spaces, offering fire-retardant properties and lower smoke toxicity. Ensure the jacket aligns with your installation area (plenum, riser, or general indoor use).
- Conductor material: 24 AWG conductors are standard, typically copper-clad aluminum (CCA) or solid copper. CCA offers cost advantages with acceptable performance for most LAN tasks; pure copper provides best straight-line performance and longevity.
- Bandwidth and distance: A 350 MHz rating supports standard Gigabit Ethernet, with performance variations depending on distance. Verify your exact run length and future needs, especially for PoE or high-bandwidth devices.
- Signal integrity: Look for low crosstalk and testing guarantees. Products claiming rigorous testing often deliver more reliable results in dense wiring closets and ceiling spaces.
- Standards compliance: Ensure cables meet ANSI/TIA-EIA 568-C.2 or equivalent standards and RoHS compliance for safe use in commercial environments.
- Installation packaging: Reputable bulk cables may come in pull-friendly boxes or reels with sequential foot markings, easing measurement and installation in long runs.
- Color options: Choose colors that match your labeling scheme and help with future maintenance and troubleshooting.
Compared perspectives:
- Cost vs. performance: CCA-based cables typically cost less but may show slightly higher resistance and marginally reduced lifespan compared to copper conductors in demanding environments.
- Indoor vs. plenum use: Even within indoor installations, plenum-rated cables offer added safety in shared air spaces, especially in commercial buildings requiring fire-retardant materials.
- Future-proofing: If you anticipate higher-speed needs (beyond Gigabit or longer PoE runs), consider higher-rated category cables or mixed cabling strategies that balance cost with performance.
