Shielded Ethernet cable spools use foil or braid around the pairs, helping reduce electromagnetic interference (EMI) and crosstalk in environments near motors, power wiring, or other noise sources. Unshielded spools can support standard network, AV, and security runs where interference is limited, while offering a simpler installation without shielded termination components.

Choose plenum-rated Ethernet cable spools for runs through air-handling spaces, such as raised floors, ducts, and drop ceilings, where the cable jacket needs a plenum rating. Choose riser-rated Ethernet cable spools for vertical runs between floors or through other nonplenum pathways, subject to local code and project requirements.

Choose a 500-foot spool for shorter or more segmented projects, or a 1,000-foot spool for longer runs and larger installations, while accounting for routing, service loops, and waste. Select a single category cable for standard network runs, a dual Cat 6 configuration for two network connections, or a bundled Cat 6 and RG-6 configuration when one pull needs to carry network and coaxial signals.

Compare solid bare copper or oxygen-free copper conductors for structured cabling, and distinguish them from copper-clad steel conductors used in some bundled cable designs. For the jacket, review unshielded, shielded, U/FTP, plenum, or riser construction, along with color, distance markings, anti-snag features, and easy-to-strip designs that can simplify termination and port identification.
