Category 6 Cables : What Are They Used For?
May 29th
It is a digital world, there is no doubt about it. Office buildings are hubs of data transmission and reception, and homes have become hotbeds of entertainment options. These digital signals may be sent by various means, such as optical fiber, cables, and wirelessly. As speedily as a signal is sent without wires, hardwiring a device often yields the quickest signal transmission speeds. Ethernet cables are often the cable of choice when it comes to propagating signals. Category 6 cables are some of the fastest Ethernet wires available, and they provide a variety of uses.
As the internet became a part of our daily lives and home theater systems and televisions became more and more sophisticated, demand for Ethernet cables rose. Consumers had grown to expect seamless audio and picture, and if this was to continue via digital signals, a cable had to be manufactured that could handle enough bits in a fast enough manner to provide the sight and sound of radio and television waves. Ethernet cables were the answer, a set of unshielded, twisted-pair (UTP) cables that received consecutive category designations as their speeds increased. Eventually, Category 6 was achieved, replacing the previous 5 and 5e standards.
The speed offered by Category 6 cables may suggest popularity amongst office buildings, but they are found most often in the home. Fiber optic and Fast Ethernet networks are usually enough for business settings, while residences require better data transmission speed thanks to the movies and music that people enjoy while in the home. Category 6 cables are best equipped to accommodate movie downloading and viewing.
We cannot forget that computers are connected to their modems with Ethernet cables. Category 6 (and 6A) is the standard bearer in transmission speed. 10 Gbits/sec is possible via Category 6 cables up to 55 meters. Signal speed and quality begin to decrease when sent over longer distances. Category 6 cables also easily handle multiple, simultaneous channels because of their speed allowances.
Category 6 cables are not found exclusively in the home. In Virginia, a hospital equipped the entire building with Category 6 cables so that patients and employees could watch television anywhere in the building. This was one of the first hospitals to do so. Wireless signals will certainly continue to improve in speed and quality as research continues; however, Ethernet cables reach superior speeds, and Category 6 cables are on top.
