Solid UTP cables use a single, solid copper conductor per wire, which supports stable signal transmission and reliable termination in fixed, in-wall, riser, or plenum runs. Stranded cables use multiple fine copper strands for greater flexibility, making them better suited to patch cords and connections that move, while solid cables can be less flexible and more prone to damage from repeated bending.

Choose plenum-rated solid UTP cable for air-handling spaces, and choose riser-rated cable for vertical runs between floors or other approved nonplenum pathways, based on local code requirements. Both options use solid, unshielded twisted-pair construction, so select the cable jacket rating that matches the installation space and pathway.

When selecting solid UTP cables, compare Cat 6 and Cat 6A categories based on the network performance your installation requires. Look for four-pair construction with 23 AWG solid bare copper conductors, and confirm whether a riser or plenum jacket suits the installation environment.

Plan solid UTP cable runs with spare pathway capacity, accessible termination points, and room for additional drops as network needs grow. Use solid bare copper cable for permanent horizontal or riser runs, select the appropriate riser or plenum jacket for the installation space, and leave service slack to simplify future changes.
