Modern information network provides many possible way of passing information between computers, servers, network center, TV, radio and telephone. Two of the most popular way to make these connections coaxial cable and optical fiber cable. Both of these types of cable can be used for carrying video, audio, and other forms of data, and both can offer you distinct advantages and disadvantages in setting up the data network of your dreams.
Coaxial cable has been widely used since about at the beginning of the twentieth century. This is a testimony to the resilience and cable quality, its universality has been able to unchallenged still more or less in their long life. Coaxial cable is the key to success is the shielding design, makes the copper core cable to transmit data fast, don’t succumb to interfere with or damage the environment factors.
All of the coaxial cable is composed of a copper core, and in turn surrounded by, and then a weaving dielectric insulation copper shield, finally a plastic sheath. These four layers allow coaxial cables to be deployed in almost any conveivable setting, and for most of the twentieth century, coax cables were the cable of choice of setting up almost every variety of communications network.
Originally, coax cable was used by the military to transmit radio and telephone signals.
Different types of coaxial cable are still differentiated today by the designation RG-a shortened version of the term Radio Guide, which was the military’s choice nomenclature for differentiating different types of cable.
As terrestrial and cable, coaxial cable into the more common everyday use. When the popularity of the internet, become China’s largest dielectric coaxial cable transmission of signals between computers all over the world.
Though coaxial cable has proven to be a resilient means of data transfer, it does have its drawbacks. Coax cables often fall victim to a phenomenon known as signal leakage, wherein imperfections in a cable’s shielding lead it to provide a weak signal that is subject to interference (this is how you wind up getting a fuzzy signal from your cable television connection).
Many different kinds of coaxial cable is available and that ir is important to find out which type is best for your data requirements, if the coaxial cable is you choose to use your network project.
Fiber Optic Cable
Whereas coaxial cable depend on the copper as medium to transmit data, the core components of the optical fiber cables simply select ultrafine glass known as silicon. Fiber optic cable is still a newly invented, only into widespread use in 1980s. Though usually more expensive than coaxial cable, optical fiber offers several advantages, will ignore any large-scale digital data network.
Instead of using electricity as a medium in which to pass information (as is the case with coaxial cables), fiber optic cable employ light to carry remarkably large amounts of data at a remarkably fast speed. Fiber optic cable will usually contains several silicon the spread of the “nuclear” increasing its capability of providing cable data transmission.
Optical fiber cable can be used in the single mode and multimode, single mode fiber cable provides a single transmission path and which data can be passed, and multimode cable provides several paths. Dual fiber optic cable can transmit data in both directions, and simplex fiber optic cable can transmit data only in one direction.
Because of their expense, relative novelty, and sophisticated design, fiber optic cables are found less frequently in residential and consumer settings than coaxial cables. Coax cables have earned a deserving reputation for being easy to install and more than able to take a beating. While fiber optic cables offer a higher quality of data transfer than coaxial cables, they are probably best employed for large-scale professional networks, such as those found within an academic or business campus. If home installation or medium-capacity data transfer is your goal, then you’d probably be better off sticking with coaxial cable.
