Solid versus Stranded Cable
What is the difference between Solid and Stranded Cable?
Networking cable comes in two versions: solid and stranded. These terms refer to the conductors. Solid cable is made of one larger solid conductor, while stranded cable is made up of many different wire strands twisted together to make one conductor. Solid cable is best suited for longer runs and outdoor installations where the cable is unlikely to be bent or manipulated, while stranded cable is better for shorter runs where the cable might be bent or curved. Most patch cables are made of stranded cable.
You may notice that stranded cable is more expensive than solid cable. This is because it requires more copper on the conductors. It is also more difficult to manufacture due to the multiple strands as opposed to one solid conductor.
