Belden Inc. 1583A 010U1000 Cat5e Utp Cmr Riser Cable

Product Description

The BELDEN INC. 1583A 010U1000 is a Category 5e, 4-pair unshielded twisted pair (U/UTP) data cable rated for riser (CMR) installations. It is designed for horizontal and vertical runs inside commercial and residential buildings where the cable must pass between floors through plenum or riser-rated pathways. The CMR rating meets NEC Article 800 requirements for riser applications, making it suitable for structured cabling systems that demand fire-rated cable in vertical runs. Licensed low-voltage technicians and network cabling contractors are the primary installers of this product.

This cable is used in structured cabling installations supporting Ethernet networks up to 1000BASE-T (Gigabit Ethernet) and 100BASE-TX Fast Ethernet. Typical applications include data drops, patch cabling backbones, and telecommunications rooms in commercial office buildings, schools, healthcare facilities, and light industrial environments. The black jacket aids identification in conduit or cable management systems where color coding by run type is a common practice.

Key Features

• Category 5e performance supports Gigabit Ethernet and Fast Ethernet applications
• U/UTP construction with 4 unshielded twisted pairs for standard structured cabling
• CMR (riser) jacket rating meets NEC Article 800 fire requirements for vertical runs
• Black PVC jacket for easy identification in multi-cable installations
• 1000-foot pull box for efficient job-site deployment

Compatibility

Designed as an OEM-style Cat5e U/UTP riser cable compatible with standard 8P8C (RJ45) termination hardware including keystone jacks, patch panels, and field-termination connectors rated for Category 5e or higher.

Installation Notes

Installation should be performed by a licensed low-voltage or network cabling technician in accordance with NEC Article 800 and TIA-568 structured cabling standards. Verify that the cable pathway is rated for CMR riser cable before pulling; do not substitute CMR-rated cable in plenum-rated (CMP) pathways. Avoid exceeding the cable bend radius during pulls to prevent pair distortion that degrades signal performance. Terminate both ends with Cat5e-rated jacks or patch panel ports to maintain channel performance.
