Avoid having excess Ethernet cable lying around by building your own cables to the exact length needed using this Bulk Ethernet Copper Cable from Monoprice! This 1000 foot roll of shielded (STP) Cat5e cable uses solid conductors and features 350MHz bandwidth capacity. Solid conductors have slightly better electrical properties than stranded conductors, making solid cables well suited for use in permanent, in-wall installations and for longer cable runs. This cable carries a CM fire safety rating, which means that it is safe for use within the walls of commercial buildings. Monoprice Cat5e and Cat6 cables are made of 100% bare copper wire, as opposed to copper clad aluminum (CCA) wire, and are therefore fully compliant with UL Code 444 and National Electrical Code TIA-568-C.2 fire and safety standards, which require pure bare copper wire in Cat5e and Cat6 communications cables. *** 30-day easy returns.
