Black Box 1000ft Cat5e 350MHz Shielded Bulk Cable (Black)

The Black Box EVNSL0508A-1000 is a shielded Cat5e bulk cable supplied on a 1000-foot spool, ready for installers who need stable network performance across long distances. It supports frequencies up to 350 MHz, a range that keeps data moving smoothly for applications such as Gigabit Ethernet, VoIP, and Power over Ethernet.

This cable meets TIA/EIA-568C Cat5e specifications, which means each pair is twisted and tested to reduce near-end crosstalk and keep attenuation low. An aluminum Mylar tape, backed by an overall foil shield, surrounds the conductors and blocks electromagnetic interference that can appear in factories, hospitals, or busy wiring closets. The black outer jacket resists abrasion and handles pulls through conduit or overhead trays without fuss.

In practical terms, the EVNSL0508A-1000 fits installers who run cable through production floors, warehouse ceilings, or school campuses where a single uninterrupted length simplifies the job. It is also a smart choice for IT teams building patch panels in data centers that need consistent performance on every port.
