Black Box EYN852A-PB-1000

Overview

The Black Box EYN852A-PB-1000 is a bulk Category 5e Ethernet cable designed for extensive network installations requiring long cable runs without frequent spool changes. It supports bandwidths up to 350 MHz, exceeding standard Cat5e requirements, which ensures reliable transmission for voice, 10BASE-T, and 100BASE-TX applications. The cable’s CMP plenum rating makes it suitable for installation in air-handling spaces, meeting strict fire-safety codes essential for commercial environments like offices, schools, and hospitals.

Key features

• Sweep tested to 350 MHz to provide extra bandwidth capacity beyond basic Cat5e standards, supporting high-demand network traffic.
• Unshielded twisted pair construction with solid conductors that minimize signal attenuation and control power-sum crosstalk for stable connections over long distances.
• CMP plenum-rated jacket ensures compliance with fire-safety regulations for use in return-air spaces, reducing installation concerns in regulated buildings.
• Comes in a 1000-foot pull box equipped with an Accu-Pull measuring system, allowing installers to see remaining cable length at a glance and plan cuts efficiently.
• TAA compliant and listed on GSA schedules, making it a practical choice for government projects requiring certified sourcing without sacrificing performance.
• Designed to simplify large-scale installations by reducing waste and speeding up setup with clear length markings and durable packaging.

Connectivity and compatibility

This cable supports standard Ethernet protocols including 10BASE-T and 100BASE-TX, making it compatible with a wide range of network devices such as switches, routers, access points, and computers. Its unshielded twisted pair design is optimized for typical office and commercial network environments where electromagnetic interference is minimal.

Installation and setup

The 1000-foot pull box with Accu-Pull measuring system streamlines installation by allowing technicians to monitor cable usage and plan cuts without guesswork. The CMP plenum rating ensures that the cable can be safely routed through ceilings, walls, and plenum spaces without violating fire codes. Solid conductors maintain signal integrity over long horizontal runs, reducing the need for additional repeaters or signal boosters.

Ideal uses and environments

This cable is well suited for commercial buildings, government facilities, schools, and healthcare environments where fire safety and regulatory compliance are critical. It works effectively for wiring offices, deploying wireless access points across campuses, or building out data center floors. Its length and performance characteristics make it a strong choice for projects requiring reliable, high-bandwidth network infrastructure with minimal installation interruptions.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
