Black Box EYN872A-PB-1000 Cat.5e UTP bulk cable yellow 1000ft

Cable for high-performance LANs

This bulk UTP cable is built for installers and network engineers who need reliable horizontal or backbone runs in commercial or campus environments. It uses 23 AWG solid copper conductors and is rated to 350 MHz for Cat.5e applications. The yellow jacket aids visual identification in dense cable trays. It suits projects that require consistent signal quality over long distances.

Pull-box design simplifies measurement

The Accu-Pull Measuring System printed on the jacket shows remaining length so you can pull exact drops without guesswork or separate measuring tools. Solid 23 AWG conductors demand proper punch-down technique and a compatible patch panel; untwisting pairs beyond the specified limit or kinking the cable during pulls will degrade high-frequency performance. The 1000 ft spool feeds cleanly from the box when handled correctly.

Cat.5e bandwidth caps at 350 MHz

The cable is tested to 350 MHz, which is the practical ceiling for the Cat.5e standard it follows; it will not carry certified Cat.6 or higher channel performance regardless of the 550 MHz material rating mentioned in the manufacturer highlights. UTP construction offers no shield against external EMI, so routing near heavy electrical gear requires separation or conduit. Full- and half-duplex operation is supported up to 1 Gbps over the standard 100 m channel.
