Belden Inc. 1585A 010Z1000 Cat5e Plenum Cable

Product Description

The BELDEN INC. 1585A 010Z1000 is a Category 5e, 4-pair unshielded twisted pair (U/UTP) data cable rated for plenum (CMP) installations. Designed for structured cabling in commercial and institutional buildings, it supports standard Ethernet network runs where air-handling spaces require a low-smoke, flame-retardant jacket. The CMP rating meets the most stringent North American plenum fire code requirements, making it the correct choice when cable must pass through HVAC air plenums or raised-access flooring used as return-air paths. Licensed electricians and low-voltage cabling technicians are the primary installers.

This cable is suited for horizontal runs in commercial office buildings, schools, healthcare facilities, and any structure where plenum-rated cabling is mandated by local fire or building codes. It supports 10BASE-T, 100BASE-TX, and 1000BASE-T (Gigabit Ethernet) applications as well as Power over Ethernet (PoE) deployments. The black jacket aids in visual identification in environments where cable color coding by zone or function is standard practice.

Key Features

• Category 5e performance supports Gigabit Ethernet and PoE applications
• CMP (plenum) fire rating meets the strictest air-handling space requirements under NFPA 90A
• U/UTP construction with 4 unshielded twisted pairs for straightforward termination
• Black PVC-compound plenum jacket for color-coded cable management
• Sold as a single unit (EA) consistent with reel or cut-length packaging

Compatibility

Designed as a standard Cat5e U/UTP structured cabling solution compatible with RJ45 keystone jacks, patch panels, and modular plugs rated for Category 5e or higher termination.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage cabling technician in accordance with NFPA 70 (NEC) Article 800 and local building codes. De-energize any circuits in the work area before pulling cable through pathways or terminating at patch panels. Do not exceed the cable minimum bend radius or install under conditions that could crimp or kink the pairs, as this degrades signal performance. Verify that all plenum-rated pathway requirements are met before substituting a non-CMP cable in any air-handling space.
