Telecommunication Trends - Fiber Optics

Fiber in our school is the medium and technology that conveys information along the light pulses of glass and plastic wires and fibers and is related to the thickness of human hair. Fiber optic lines transmit more information than traditional copper wires and are less susceptible to electromagnetic interference. A single glass fiber can carry a television equivalent to 100 channels or 100,000 phones, and by encapsulating multiple fibers with one cable, you can achieve a larger capacity.

Copper cables have been a traditional choice for telecommunications, networking, and cable connections for many years, but optical fibers have become a common alternative. Long distance lines of most telephone companies are currently made of optical fiber cables. Due to the wide bandwidth and fast speed, optical fiber carries more information than traditional copper wire. Since the glass is not conductive, the fiber is not subject to electromagnetic interference and signal loss is minimized. Furthermore, it can be used in a low-risk environment such as a submarine cable by immersing the optical fiber cable in water. Because optical fiber cable is stronger, thinner and lighter than copper cable, frequent maintenance and replacement are not necessary. Copper wires, however, are usually cheaper than optical fibers and are already installed in many areas where fiber optic cables have not yet been deployed.

Fiber optic cables are communication cables, common fiber consists of five parts: fiber core, cladding, buffer layer, reinforcement, and jacket. The fiber core at the center of the optical fiber cable is an optical transmission line. In addition to this, there are claddings coated with acrylate polymers or polyimides. When light passes through the core, it is reflected at the junction of the core and the clad and returns to the core. And the cladding acts as a protective device to ensure that the fiber can be transported along the core. The buffer layer is typically made of plastic and surrounds the cladding to protect the core and cladding from damage. Reinforcement materials are used to enhance the toughness and strength of the fibers so that the fibers do not break during installation. The jacket, also known as protective equipment, acts as a final protective layer to prevent melting, wear and damage.
