Superior Essex 51-499-48 Cat5e Plenum Cable White

Product Description

The SUPERIOR ESSEX 51-499-48 is a CAT5e plenum-rated communications cable intended for structured wiring installations in commercial and residential buildings. Plenum-rated jacketing meets the fire and smoke requirements for cables routed through air-handling spaces, including above-ceiling plenums and raised-floor return-air plenums. The 25x24 AWG configuration indicates a 25-pair, 24 AWG conductor arrangement, providing high-density voice and data capacity in a single cable run. Low-smoke, flame-retardant jacket material is required by code in plenum spaces, making this cable appropriate where standard PVC-jacketed cable is not permitted.

This cable is used in commercial structured cabling systems, large office builds, hospitality, education, and healthcare facilities where multi-pair runs are needed between telecom rooms and distribution points. It is typically installed by licensed low-voltage or communications cabling contractors following ANSI/TIA-568 standards. The white jacket aids in cable identification in high-density tray and conduit environments. Sold as a master reel, this product is suited for large-scale installation projects requiring significant cable quantities.

Key Features

• Plenum-rated jacket meets fire and smoke propagation requirements for air-handling spaces
• 25-pair, 24 AWG conductor configuration supports high-density voice and data distribution
• CAT5e performance supports data rates up to 100 MHz for standard Ethernet and structured wiring applications
• White jacket provides visual differentiation in multi-cable tray and conduit installations
• Master reel format reduces mid-run splices on large commercial jobs

Compatibility

Designed for use in CAT5e and higher structured cabling systems installed in plenum air-handling spaces per ANSI/TIA-568 and applicable local fire codes.

Installation Notes

Installation should be performed by a qualified low-voltage or communications cabling technician in accordance with ANSI/TIA-568 and applicable NEC Article 800 requirements for plenum-rated communications cable. De-energize all adjacent circuits before pulling cable through shared pathways. Do not exceed the cable manufacturer minimum bend radius or maximum pulling tension during installation, as deforming the pairs can degrade CAT5e performance. Verify that the plenum rating on the cable jacket matches the air-handling classification of the space before installation.
