From the ancient period to present day, wired technology has more benefits in providing its service of accessing internet without any disturbances from other signals. Because of its high speed transmission of information and reliability service, the wired technology has becoming more familiar for internet connection. There are several types of cables are used in the wired technology for easy and high speed transfer. Let have a look about the types of cables. The first and foremost cable used in wired is twisted pair cable. It is made of copper cables which are twisted together to form a pairs.
The ordinary telephone connections, Ethernet cables are made of this twisted pair cables but the count used will vary. For telephone cables, two pairs are used and in Ethernet, four cables are used in order to transfer both voice and data. These insulated copper wires avoid cross-talks and other electromagnetic radiations. It is of two types as shielded and unshielded and is used in various scenarios. Next, coaxial cables are introduced which is made of copper/aluminium wires with insulating layer. This insulating layer avoids interference occurrence during transmission. The speed of transmission is more as compared with twisted-pair cables. These cables are used in homes, offices and in local areas for connection.
Next advancement in cables produces optical fiber cable for transmission. This uses light pulses for transmission. It has more advantages as compared with other cables such as low loss in transmission, provides insulation from electromagnetic emission and has fast transmission rate up to trillion of bits per second. Everyone can use various color of light pulses in order to increase the transmission speed. As more advantages are seen, nowadays optical fibers are used in wired technology for fast transmission.
