Black Box 1000ft Plenum CAT5e 350-MHz Solid Ethernet Cable (Black)

Overview

The Black Box EYN860A-PB-1000 is a bulk spool of CAT5e Ethernet cable designed to deliver reliable network connectivity over long distances. With a bandwidth tested up to 350 MHz, it supports voice, 10BASE-T, and 100BASE-TX data transmissions while minimizing signal loss and crosstalk. Its plenum-rated CMP jacket allows safe installation in air-handling spaces, making it suitable for commercial buildings such as offices, schools, and hospitals.

Key features

• 350 MHz sweep testing provides extra bandwidth headroom for stable network performance.
• Four twisted pairs of solid copper conductors reduce attenuation and maintain signal integrity over long runs.
• Plenum-rated CMP jacket ensures compliance with building codes for installation in air plenums and return-air spaces.
• Built-in pull box and internal rip cord enable quick and clean jacket removal, speeding up installation.
• Sequential two-foot markings on the cable simplify measurement and help reduce waste during deployment.
• TAA compliance and GSA certification guarantee suitability for government and regulated environments.

Connectivity and compatibility

This cable supports standard CAT5e network protocols including 10BASE-T and 100BASE-TX, making it compatible with a wide range of Ethernet devices such as switches, routers, and network interface cards. Its solid copper conductors and twisted pair design help maintain consistent throughput in structured cabling systems.

Installation and setup

The cable’s design includes practical features that simplify installation. The pull box packaging allows easy dispensing of the cable, while the internal rip cord helps technicians strip the jacket cleanly without damaging the conductors. Sequential markings every two feet assist in precise cable measurement, reducing material waste and installation time.

Ideal uses and environments

This CAT5e cable is well suited for commercial and institutional environments where network reliability and code compliance are critical. It works well in office buildings, schools, hospitals, and government facilities, especially where cable must be routed through plenum spaces such as drop ceilings or ventilation returns. Its TAA compliance also makes it a strong choice for federal contractors and regulated installations.
