Ethernet cables connect devices such as PCs, routers, and switches within a local area network.Most technicians refer to these standards as CAT5 and CAT6, respectively. Also CAT3 available. Because of this, many online stores that sell network cables use this abbreviated language as well.
The connector can by shield or non-shield type, raw cable can be UTP, STP, FTP type. Also the molded shape can be custom mould by straight, right-angle, 105 degree, etc.
These physical cables are limited by length and durability. If a network cable is too long or of poor quality, it won't carry a good network signal. These limits are one reason there are different types of Ethernet cables that are optimized to perform certain tasks in specific situations.
