Optical Cables: Cutting Edge Technology

by:ChangHui     2020-04-09
Typically, optical cables are used for audio connections, but they are also used for a multitude of applications. For instance, they are utilized for computer connections, but new devices create a demand for cables with higher capabilities. This is why manufacturers continuously work to come up with superior cables that are able to meet current needs. Buyers should invest in good quality cables. Some people are not willing to spend more and would resort to buying cheap cables and devices. However, cheap cables would prove to be cheap in the end. These old cables may no longer be compatible with future devices. Components of an Optical Cable This is a cable that is made of optical fibers with strong resin coating which is then encased in a plastic layer. The plastic layer is known as the jacket layer, which gives the cable its' durability but does not affect the signal transmission ability of the optical fibers. The fibers, on the other hand, are made of special types of plastic or glass that are transparent. Hence, the fibers are capable of transmitting light signals or electricity. They allow transmission of huge amounts of data and also make it possible to provide a medium for data transfer through a bandwidth connection. Protective Coating Cables that use optical fibers come in different coatings, and the type of coating depends on how the cable will be used. The coating generally serves to protect the fibers inside from the external environment. Protecting the fibers is necessary as they transmit signals, which should remain unchanged as much as possible throughout their journey along the entire length of the cable. Cables that are installed in tough environments need to have stronger protective coverings. Inevitably, most cables pass through various harsh environments from their sources. They may have to be attached along power lines, buried underground, or installed underwater. Indoor and Outdoor Cables Cables used for home or studio equipment may only have a light plastic jacket. These consumer grade cables have optical fiber connectors at both ends that allow connection between common devices, say computers and speakers. Optical cables that have to be used outdoors have loose interiors but more rigid coverings. The combination of loose insides and a firm exterior gives these cables some resistance against the weather and other damaging forces. Waterproof Sheathing Generally, cables have waterproof jackets regardless of their type. Outdoor, indoor, home, and industrial cables should have waterproof casings to prevent electrical failures. Moreover, optical fibers must not be exposed to water, which has an ionizing effect on the fibers. Once the fibers come in contact with moisture, their performance is affected. Optical fibers can also suffer from reduced strength and stability once they become wet. Manufacturers ensure that the fibers are completely locked in to prevent seepage of water. This protective sheathing plays a crucial role in underwater cables. Wide Usage The market for optical fiber cables ranges from average consumers to huge industries. Manufacturers have answered these needs by creating a wide range of cables to match the diverse needs of buyers.
