Solid Core Cable Vs Stranded Cable
A solid core cable uses one solid wire per conductor and in a four pair cable there would be a total of eight solid wires. Stranded conductor uses multiple wires wrapped around each other in each conductor and in a four pair with seven strands per conductor cable, there would be a total of 56 wires (2 per pair x 4 pairs x 7 strands).
Solid core cable is supposed to be used for permanently installed runs. It is less flexible than stranded cable and is more prone to failure if repeatedly flexed. Stranded cable is used for fly leads at patch panel and for connections from wall-ports to end devices, as it resists cracking of the conductors.
Connectors need to be designed differently for solid core than for stranded. Use of a connector with the wrong cable type is likely to lead to unreliable cabling. Plugs designed for solid and stranded core are readily available, and some vendors even offer plugs designed for use with both types. The punch-down blocks on patch-panel and wall port jacks are designed for use with solid core cable.

Famous quotes containing the words solid, core, cable and/or stranded:
“The acceptance that all that is solid has melted into the air, that reality and morality are not givens but imperfect human constructs, is the point from which fiction begins.”
—Salman Rushdie (b. 1947)
“The ideal of men and women sharing equally in parenting and working is a vision still. What would it be like if women and men were less different from each other, if our worlds were not so foreign? A male friend who shares daily parenting told me that he knows at his very core what his wife’s loving for their daughter feels like, and that this knowing creates a stronger bond between them.”
—Anonymous Mother. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 6 (1978)
“To be where little cable cars climb halfway to the stars.”
—Douglass Cross (b. 1920)
“It is the blankness that follows gaiety, and Everyman must depart
Out there into stranded night, for his destiny
Is to return unfruitful out of the lightness
That passing time evokes.”
—John Ashbery (b. 1927)
