There are two types of twisted pair cables according to the RJ connectors.
Stranded-Conductor Twisted Pair Cable
Stranded-conductor twisted-pair cable is made up of many tiny hairlike strands of copper twisted together into a larger conductor. These conductors have more surface area to make contact with but are more difficult to crimp because they change shape easily. Because of their difficulty to connect, they are usually used as patch cables.
Solid-Conductor Twisted Pair Cable
Most UTP cable installed in the walls and ceilings between patch panels and wall plates is solid-conductor cable. Although they are not normally used as patch cables, solid-conductor cables are the easiest to connect, so many people make their own patch cords out of solid conductors.
