Nippon Labs 50CPE-5E-SD-1K-WH 1000 ft. Bare Copper 24AWG CMR UTP Cat5e Bulk Cable, 350MHz, Solid Wire - White

Manufactured in accordance to ANSI/TIA-568-C.2 standards, these Category 5e (Cat5e) solid wire cables are used for horizontal and backbone cable runs and come in a bulk spool of 1000ft, inside a pull box for efficient cable runs. Additionally, 2ft increments are marked on the cable for keeping track of the usage.

Our bulk Cat5e cables are CMR rated (UL-1666 standard) and can be used to run between floors through risers or vertical shafts in non-plenum areas.

Solid wire cables feature a single strand (metal wire) that's typically used for long distance runs (up to 100 meters). They are typically used in horizontal or backbone cabling. A horizontal cabling system extends from the work area of a telecommunications outlet to the horizontal cross-connect of the telecommunications room. A backbone cabling system interconnects networks through telecommunications rooms, equipment rooms, and building entrances.

These cables are engineered to the tightest tolerances to deliver unwavering reliability during mission critical and stress intensive applications and are designed for both commercial or residential installations.

Note: For most commercial or residential installations, bare copper conductors need to used.
