Belden Inc. 1585A 009Z1000 Cat5e Plenum Cable

Product Description

The BELDEN INC. 1585A 009Z1000 is a Category 5e, 4-pair unshielded twisted-pair (U/UTP) cable rated for plenum (CMP) installation. It is designed for structured cabling systems in commercial and institutional buildings where the cable must pass through air-handling plenum spaces. The CMP rating meets the flame and smoke requirements of NFPA 90A, making it suitable for use in return-air plenums without conduit in many jurisdictions. Licensed low-voltage cabling technicians and electrical contractors are the primary installers of this product.

This cable is used in horizontal runs connecting workstation outlets to telecommunications closets or equipment rooms. It supports Ethernet, VoIP, and other data applications in office buildings, schools, hospitals, and similar commercial environments. The white jacket finish is common in drop-ceiling plenum runs where visibility and identification during future service work matter. This cable ships on a 1000-unit reel as indicated by the suffix in the part number.

Key Features

• Category 5e performance supports 100 MHz bandwidth and Gigabit Ethernet applications
• U/UTP construction with 4 unshielded twisted pairs for standard structured cabling installations
• CMP (Communications Multipurpose Cable, Plenum) jacket rating meets NFPA 90A flame and smoke requirements
• White jacket for easy identification in plenum ceiling spaces
• Suitable for use without conduit in plenum air-handling spaces where CMP is the required rating

Compatibility

Designed as an OEM-style structured cabling solution compatible with standard Cat5e patch panels, keystone jacks, and RJ-45 termination hardware in commercial horizontal cabling applications per TIA-568 standards.

Installation Notes

Installation should be performed by a licensed low-voltage technician or electrical contractor familiar with TIA-568 structured cabling standards and local building codes. De-energize any adjacent live circuits before working in ceiling or wall cavities. Avoid exceeding the cable minimum bend radius and do not cinch cable ties so tightly that they deform the jacket or alter pair geometry, as this can degrade Cat5e performance. Plenum-rated cable must be used in any air-handling space unless the Authority Having Jurisdiction permits an alternative wiring method.
