Cat5e Riser Solid Bare Copper 1000ft Ethernet Cable Black — Technical Overview
Looking for a professional-grade installation standard? The 52Networks Cat5e Riser Solid Bare Copper 1000ft Ethernet Cable Black (SKU: 52N-5CMR-BC-BLK) is engineered for commercial, enterprise, and contractor network installations requiring strict NEC riser-rated fire safety compliance and pure solid copper performance. Built with 24 AWG 100% solid bare copper conductors and High-Density Polyethylene (HDPE) insulation, it exceeds ANSI/TIA-568.2-D standards up to 350MHz. It delivers flawless 1000BASE-T Gigabit Ethernet up to 328ft (100m) and robust IEEE 802.3af/at PoE+ support without the voltage drop, signal attenuation, or code violations associated with Copper-Clad Aluminum (CCA) cables.
Built for Vertical Riser Shafts, Pure Copper Conductivity & Exposed Dark Ceilings
When running network and security cabling vertically between floors inside wall cavities, utility risers, or non-plenum vertical shafts, low-grade aluminum-alloy (CCA) cables introduce high electrical resistance and brittle punch-down failures that violate professional contractor standards. Under the National Electrical Code (NEC Article 800), vertical runs require a certified CMR (Communications Multipurpose Cable, Riser) rating.
Our Cat5e Riser Solid Bare Copper 1000ft Ethernet Cable Black combines 100% pure annealed bare copper performance with code-compliant CMR riser safety and a discreet matte black jacket designed to blend seamlessly into open industrial ceilings, stage rigging, and black server racks. Low-voltage integrators rely on solid copper black riser cable to ensure permanent link stability. Need plenum-rated runs or other colors?

Core Engineering & Pure Copper Performance Advantages
⚡ 100% Pure Solid Bare Copper (24 AWG)
Zero CCA. Annealed pure solid copper conductors guarantee maximum conductivity, minimal DC resistance, and lifelong mechanical termination strength at patch panels and keystone jacks.
🔥 CMR Riser Fire-Safety Rating
UL Listed riser-rated PVC jacket engineered to resist vertical flame propagation between building floors, complying with NEC Article 800 CMR building codes.
🔋 PoE & PoE+ Power Stability
Fully compliant with IEEE 802.3af (PoE) and 802.3at (PoE+ up to 30W), supplying stable DC power and data to PoE IP cameras, VoIP desk phones, and network switches.
🛡️ 350MHz Gigabit Bandwidth
Swept and tested up to 350MHz, delivering flawless 1000BASE-T Gigabit Ethernet data transmission up to the full 328ft channel limit.

Frequently Asked Questions (FAQ)
A: This cable is 100% Pure Solid Bare Copper (24 AWG) — we never use Copper-Clad Aluminum (CCA). Pure copper is essential for professional network installations because it meets strict fire codes, prevents brittle wire breakage at punch-down blocks, and ensures stable Power over Ethernet (PoE+) performance.
A: CMR (Communications Multipurpose Cable, Riser) is a fire safety rating defined by the National Electrical Code (NEC Article 800) for cables running vertically between floors in non-plenum vertical shafts or wall cavities, designed to prevent fire from spreading upward.
A: Black riser cable is the preferred choice for exposed industrial ceilings (such as in retail stores, restaurants, or loft offices) where ductwork and trusses are painted black, as well as for clean cable management inside black server racks.
A: Yes, it is rated up to 350MHz and fully supports 1000BASE-T Gigabit Ethernet up to 328 feet (100 meters).
A: Yes, its solid bare copper conductors fully support IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) for IP cameras, access points, and VoIP hardware without thermal overload.
