Cat5e Plenum CMP 1000ft Ethernet Cable Black — Technical Overview
Looking for a code-compliant plenum network solution? The 52Networks Cat5e Plenum CMP 1000ft Ethernet Cable Black (SKU: 52N-5CMP-BLK) is an indoor commercial-grade unshielded twisted pair (U/UTP) bulk networking cable engineered specifically for environmental air-handling plenum spaces, drop ceilings, and raised subfloors. Constructed with 24 AWG 4-pair conductors, FEP/low-smoke insulation, and a fire-retardant CMP plenum-rated black outer jacket, it supports 350MHz bandwidth and 10/100/1000 Mbps Gigabit Ethernet (1000BASE-T) up to 328ft (100m). Compliant with NEC Article 800 CMP, NFPA 262, ANSI/TIA-568.2-D, and RoHS standards, it ships in a tangle-free 1000ft Easy Pull Box for fast deployment across commercial offices, schools, hospitals, and government facilities.
Engineered for HVAC Plenum Drop Ceilings, Exposed Ceilings & Server Racks
When routing structured network cabling above drop-ceiling tiles or underneath raised floors used for HVAC air return, standard PVC riser cables violate commercial fire codes and release toxic black smoke if exposed to flames. Under the National Electrical Code (NEC Article 800) and NFPA 262, environmental air-handling spaces strictly mandate a CMP (Communications Multipurpose Cable, Plenum) rating.
Our Cat5e Plenum CMP 1000ft Ethernet Cable Black satisfies commercial fire marshals and building inspectors with a low-smoke, flame-retardant jacket while providing a discreet matte black finish designed to blend invisibly into open industrial ceilings, stage rigging, and black 4-post server racks.

Core Engineering & Plenum Safety Advantages
🔥 CMP Plenum Fire-Safety Jacket
Formulated with a specialized low-smoke, flame-retardant compound rated to NFPA 262 / NEC Article 800 CMP standards—preventing flame spread and toxic smoke generation in HVAC air-return ceilings.
⚡ 350MHz Gigabit Headroom
Swept and tested up to 350MHz—more than triple the standard 100MHz Cat5e requirement—ensuring reliable 10/100/1000BASE-T Gigabit Ethernet transmission with minimal crosstalk.
🎯 Discreet Architectural Black Jacket
Blends invisibly into open black ceilings, wire-mesh cable baskets, and server racks for a clean professional aesthetic.
📦 Tangle-Free 1000ft Easy Pull Box
Packaged in a reinforced job-site pull box with a wide payout tube and sequential 2-foot footage markings printed along the jacket for snag-free J-hook and ceiling pulls.
Key Features of Cat5e Plenum CMP 1000ft Ethernet Cable Black
- CMP Plenum Fire Rating: Approved for installation in commercial air-handling drop ceilings, HVAC return ducts, and backwards-compatible with CMR riser runs.
- 24 AWG 4-Pair U/UTP Construction: Precision-twisted pairs minimize Near-End Crosstalk (NEXT) and electromagnetic interference (EMI) across indoor runs.
- 350MHz High-Speed Bandwidth: Supports 10BASE-T, 100BASE-TX Fast Ethernet, and 1000BASE-T Gigabit Ethernet up to 328 feet (100 meters).
- PoE Application Ready: Suitable for powering VoIP desk phones, wireless access points, and IP surveillance cameras when installed within applicable PoE guidelines.
- Universal Termination Compatibility: Terminates cleanly into standard Cat5e RJ45 Keystone Jacks, Cat5e Patch Panels, and RJ45 crimp connectors.
- Sequential Footage Markings: Marked every 2 feet along the outer jacket so technicians can measure exact run lengths and track remaining cable in the box.
- Discreet Black Aesthetic: Ideal for exposed ceilings and AV installations.

Frequently Asked Questions (FAQ)
A: CMP stands for Communications Multipurpose Cable, Plenum. Under NEC Article 800 and NFPA 262, CMP cable is mandatory whenever network wiring is installed inside environmental air-handling spaces—such as above drop ceilings or under raised floors that serve as HVAC air return ducts. Its jacket is engineered to self-extinguish and emit minimal smoke in the event of a fire.
A: Yes. Under NEC fire hierarchy rules, CMP Plenum is the highest indoor fire rating and can legally substitute for CMR (Riser) or CM general-purpose cable anywhere inside a building.
A: Black plenum cable is ideal for exposed industrial ceilings (such as loft offices, restaurants, or retail stores) where ductwork and open trusses are painted black, as well as for clean cable management inside black server racks.
A: This Cat5e bulk cable is tested up to 350MHz and supports full 10/100/1000 Mbps (1 Gbps Gigabit Ethernet) at distances up to 328 feet (100 meters) when installed within standard ANSI/TIA channel guidelines.
A: Every box contains 1000 feet (305 meters) of black Cat5e CMP plenum cable wound inside a heavy-duty, tangle-free Easy Pull Box with sequential footage markings printed every 2 feet along the jacket.
