What is Cat 8 Cable?

Cat 8 cable, or category 8 cable is a shielded, copper twisted-pair communications cable. It is the latest ratification of twisted cable systems, which was implemented under ANSI/TIA 568-C.2-1. The International Organization of Standards (ISO) equivalent is expected to ratify in either 2017 or 2018. Cat 8 cable can be used to link Television, computer data, video, audio, and various other data systems to a given data center. While Cat 8 offers high speeds and strong connections, it is relatively short ranged and designed for use in data centers, not office wiring and connection. To reiterate, Cat 8 can be used to strengthen a data center’s performance levels significantly with a bandwidth four times larger than Cat 6A. On the other hand, it would not be practical to wire an office’s phones or computers due to its length limitations. All other category cables have a length of 100 meters compared with Cat 8’s 30 meter length. Cat 8 is divided between two classes, class I and class II, or Cat 8.1 and Cat 8.2. The differences between the two being shielding types and connector compatibility.
