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:
“I stand in awe of my body, this matter to which I am bound has become so strange to me. I fear not spirits, ghosts, of which I am one,—that my body might,—but I fear bodies, I tremble to meet them. What is this Titan that has possession of me? Talk of mysteries! Think of our life in nature,—daily to be shown matter, to come in contact with it,—rocks, trees, wind on our cheeks! the solid earth! the actual world! the common sense! Contact! Contact! Who are we? where are we?”
—Henry David Thoreau (1817–1862)
“It is possible to have a strong self-love without any self-satisfaction, rather with a self-discontent which is the more intense because one’s own little core of egoistic sensibility is a supreme care.”
—George Eliot [Mary Ann (or Marian)
“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)
