Liberty AV 24-4P-P-L6-EN-BLU 1000 ft Reel of Cat6 U/UTP EN Series 23 AWG 4 Pair Unshielded Cable

Product Overview

The Liberty AV 24-4P-P-L6-EN-BLU is a 1000-foot reel of Category 6 U/UTP EN Series plenum-rated cable in blue for commercial network and AV infrastructure in air-handling spaces. The cable uses 23 AWG solid annealed bare copper conductors, fluoropolymer (FEP) insulation, and a plenum-rated PVC jacket certified NEC CMP and CEC CMP FT6 for installation in return-air ceiling plenums without conduit. Independently tested to 550 MHz with a positive ACR specification, this cable is UL Listed and ETL Verified to ANSI/TIA-568-C Category 6. The blue jacket supports color-coded structured cabling standards, such as ANSI/TIA-606 infrastructure labeling, where blue designates horizontal network drops.

Product Description

The EN Series designation sets this cable apart from commodity plenum Cat6 through its fluoropolymer conductor insulation. Fluoropolymer (FEP) provides lower capacitance (14.0 pF/ft), more consistent impedance across temperature changes, and superior dielectric stability compared to the HDPE insulation used in standard Cat6. This translates to reliable high-frequency performance in the elevated-temperature environments common in commercial plenum spaces and better channel headroom for long horizontal runs near the 100-meter TIA limit.

The four twisted pairs use varying lay lengths to minimize alien crosstalk, and each pair is maintained in a fluoropolymer X-separator interstice that keeps pair geometry consistent throughout the cable. Color striping on white conductors follows TIA-568 pair color conventions for consistent field identification. A ripcord under the jacket enables clean jacket removal without cutting into conductor insulation. The 0.220-inch outside diameter is compatible with standard Cat6 installation hardware, wall plates, and conduit fill calculations. Blue jacket color aligns with ANSI/TIA-606 identification standards and common data cabling conventions that designate blue for horizontal network runs to workstations and AV endpoints.

Key Features

• 23 AWG Solid Annealed Bare Copper — Low DC resistance (≤20.12 Ω/1000 ft) supports full 100-meter horizontal channels per TIA-568.
• Fluoropolymer (FEP) Insulation — Lower capacitance and superior dielectric stability vs. HDPE for reliable Cat6 performance in plenum temperature environments.
• Tested to 550 MHz, Positive ACR — Exceeds the 250 MHz minimum for ANSI/TIA-568-C Category 6, providing headroom for longer runs and higher-frequency applications.
• Fluoropolymer X-Separator — Maintains pair geometry and pair separation for consistent crosstalk performance across the cable run.
• Varying Lay Twisted Pairs — Each pair uses a different twist rate to minimize near-end and alien crosstalk between the four pairs.
• NEC CMP Plenum Rating — Approved for open air-handling plenum installation without conduit per NEC Article 800.
• CEC CMP FT6 Rated — Satisfies Canadian Electrical Code requirements for plenum cable installations.
• Blue Jacket Color — Aligns with ANSI/TIA-606 color-coding standards for horizontal data runs; simplifies cable identification in large structured cabling installations.
• Ripcord Under Jacket — Enables controlled jacket removal without risk of damaging conductor insulation during termination.
• Third-Party Certified (UL/ETL) — Independently verified to ANSI/TIA-568-C Category 6 standards, not manufacturer self-tested only.
• 1000-Foot Bulk Reel — Standard commercial structured cabling format for large deployments.

Frequently Asked Questions

Why choose the blue version over the black version (24-4P-P-L6-EN-BLK)?

Both cables are electrically identical EN Series Cat6 CMP plenum cables with the same 23 AWG conductors, FEP insulation, and performance specifications. Blue is the ANSI/TIA-606 standard color for horizontal network cabling runs to workstations and AV endpoints. Specifying blue cable in a structured cabling installation where the color convention is followed simplifies cable identification, maintenance, and moves/adds/changes for facilities management teams.

What is the EN Series and how does it differ from standard Cat6 plenum cable?

The EN Series uses fluoropolymer (FEP) conductor insulation rather than the HDPE used in commodity Cat6. FEP provides lower capacitance, better dielectric stability across temperature variations, and more consistent impedance characteristics. This results in better electrical performance in the elevated ambient temperatures of commercial plenum spaces and greater channel headroom on runs approaching the 100-meter TIA limit.

Is this cable suitable for HDBaseT and 4K AV over IP installations?

Yes. This cable meets ANSI/TIA-568-C Category 6 requirements and is appropriate for HDBaseT and most 4K AV over IP systems that specify Cat6 cabling. Consult the extender or transmitter manufacturer for maximum recommended run length and any shielding requirements specific to their product.

Does this cable support PoE and IEEE 802.3bt (4PPoE)?

Yes. 23 AWG solid copper conductors support PoE, PoE+, and IEEE 802.3bt 4PPoE within the current-handling specifications for Category 6 cable. For high-density PoE deployments, ensure proper cable bundling practices and conduit fill to manage thermal load, as bundled cables running high PoE currents can exhibit elevated jacket temperatures.

What does NEC CMP mean for in-ceiling installation in a commercial building?

CMP (Communications Multipurpose Plenum) is the NEC rating for cable approved for installation in return-air plenum spaces without conduit. Commercial building ceilings above the tile are typically used as air-return plenums for HVAC systems. NEC Article 800 requires CMP cable in these spaces; non-plenum cable requires conduit. CMP jackets are formulated to resist flame propagation and minimize toxic smoke in a fire event.

What is the maximum run length for this cable on a standard Ethernet channel?

Per ANSI/TIA-568-C, the maximum horizontal channel is 100 meters (328 feet) including patch cords. The permanent link (without patch cords) is limited to 90 meters (295 feet). For HDBaseT, the same 100-meter limit applies for standard range; some HDBaseT products may specify shorter distances for specific signal types.

How should I handle and store plenum cable before installation?

Store in a dry environment at room temperature. Condition the cable at room temperature for at least 24 hours before installation if it has been stored in cold conditions. Do not install below 32°F (0°C) ambient, as cold temperatures reduce jacket flexibility and increase the risk of insulation damage during pulls. Do not exceed 25 lbs (111 N) maximum pull tension, and maintain the 4.40" minimum bend radius under load.

Is this cable approved for Canadian commercial projects?

Yes. The CEC CMP FT6 rating satisfies Canadian Electrical Code requirements for plenum cable, making this cable approved for commercial AV and IT infrastructure projects in both US and Canadian jurisdictions. Both US and Canadian ratings are printed on the cable jacket.
