A patch cable, patch cord or patch lead is an electrical or optical cable used to connect ("patch in") one electronic or optical device to another for signal routing. Devices of different types (e.g... a switch connected to a computer, or a switch to a router) are connected with patch cords.
A "booted" patch cable is a cable that has a molded plastic boot that is either integral to the connector, or“slips” on the RJ45 connector and a portion of the cable itself. Sometimes a booted cable is also referred to as a "strain-relief" cable, which is exactly the purpose of the boot…
People sometimes ask us what snagless or snag-less ethernet cable means. Put simply, this refers to your plain everyday Ethernet (IEEE 802.3) cable that has a little “boot” covering the hook on the plug. The reason for this is simple.
A non-booted assembly takes up less room in a high density environment and is easier to plug in and out. Booted: The booted cable gives the assembly additional strain relief. It also makes it easier to remove the cable from a bundle due to its snag-free tab.
Shielded cable is more expensive than unshielded cable and more difficult to install; it's stiffer, making it less flexible. The cable also has a larger diameter, taking up more space in conduit. UTP, on the other hand, actually provides faster transmissions in the absence of EMI.
