Category Cable Types

Category cables commonly refer to 100 Ohm twisted pair Ethernet cables. These cables are also known as: LAN (Local Area Network), data, and networking cables. The term “category” defines the type, application, and electrical performance of the cable. CATx is an abbreviation for the category number that defines the performance of building telecommunications cabling as outlined by the Electronic Industries Association (EIA) standards.

The most common cable Category cables on the market today are indicated in the chart below:
