Optical fiber refers to technology associated with the transmission of information, such as pulses of light along a fiber, fibreglass or plastic. It is used for remote and high-performance networks.

Optical fibers are also commonly used in telecommunications services such as the Internet, television and telephones. For example, companies such as Verizon and Google Fiber Verizon use FIOS and Google Fiber in their services to provide users with gigabit Internet speeds.

Fiber optic cables is used because they have many advantages over copper cables, e.g. Great bandwidth and transmission speed

A fiber optic cable may contain a different number of these fibers, from a few to a few hundred. Around the glass fiber core is another layer of glass, called a cladding. A so-called protective layer protects the coating and a coating layer acts as the last protective layer for the single thread.

How Fiber Optics Work:

Fiber transmits data in form of light particles, or photons, that pulse through a fiber optic cable. The glass fibre core and the coating have a different refractive index, which doubles the incident light at a given angle. When the light signals are transmitted through the fiber optic cable, they reflect by a process called total reflection in a series of zigzag jumps of core and deck. Due to the denser layers of glass, the light signals do not move at the speed of light, but are approximately 30% slower than the speed of light. To amplify the signal, repeaters sometimes have to regenerate remotely, become an electrical signal, a process that electrical signal and retransmit the optical signal in the transmission of optical fibers.

Fiber optic cables currently support signals of up to 10 Gbps. The higher the bandwidth of a fiber optic cable, the more expensive it usually is.

Types of fiber optic cables

Multimode fiber and single-mode fiber are two main types of fiber optic cables. Singlemode fibers are used for longer distances because the diameter of the fiber core is smaller, reducing the attenuation potential: reducing signal strength. The smaller aperture isolates the light in a single beam, providing a more direct path and allowing the signal to travel a greater distance. Singlemode fiber also has a much higher bandwidth than multimode fiber. The light source used for single-mode fibers is typically a laser. Singlemode fibers are usually more expensive because they require accurate calculations to produce laser light in a smaller aperture.

Multimode fibers are used for shorter distances because the light signals are more reflected and reflected from the larger central aperture. Due to the larger diameter several light pulses can be transmitted simultaneously over the cable, which leads to a larger data transmission. However, this also means that the probability of a signal loss, a reduction or a disturbance is higher. Multimode optical fibers generally use an LED to generate the light pulse.

While copper cables have been the traditional option for telecommunications, networks and cable connections for years, fiber Optics have become a common alternative. Most telephone company trunks today are made of fiber optic cables. Fiber transmits more information than traditional copper cables because of the higher bandwidth and speed. Since the glass conducts no current, the optical fiber is not subject to electromagnetic interference, and the signal losses were minimized.

 

Advantages and Disadvantages :

Fiber optic cables mainly used because of their advantages over copper cables. The advantages include:

  •         Support for higher bandwidths.
  •         The light can propagate without much signal amplification.
  •         They are less susceptible to interference, z. B. against electromagnetic interference.
  •         They can be submerged in water., e.g: Underwater cable.
  •         Fiber optic cables are stronger, thinner, lighter than copper cables.
  •         It doesn't have to be taken care of or changed so often.

However, it is main to keep in mind that optical fibers have disadvantages that users should know before handling them. These disadvantages include:

  • Copper wire is cheaper than fiber Optics.
  • Glass fibers also require more protection in an external cable than copper.
  • The installation of new cables requires a lot of labour.
  • Fiber optic cables are often more fragile. For example, the fibers may break, or a signal may be lost if the cable bends a few centimetres in radius.

Fiber optics Uses :

Computer networks are an everyday use case for fiber because fiber can transport data and provide high bandwidth. Similarly, in broadcasting and electronics, fiber is often used to provide better connectivity and performance. Fiber optic can be installed to support remote connections between computer networks in different locations.

In the military and aviation industry, temperature sensors and Optical fibers are used as a means of communication and signal transmission. Fiber optic cables can be advantageous due to their lower weight and smaller size. Fiber optic is commonly used in a variety of medical instruments to ensure precise illumination. It also increasingly allows biomedical sensors to help with minimally invasive medical procedures. Since Optical fibers are not susceptible to electromagnetic interference, it is ideal for a variety of tests, such as magnetic resonance imaging. Other medical applications for optical fibers include x-ray images, endoscopy, phototherapy and surgical microscopy.

If you've dreamed of a career in fiber optic technology or fiber optic cable jobs, now is the time to set foot in the door. At present, fiber offers many exciting opportunities for different types of businesses, Internet providers offering broadband communications services to medical device manufacturers and military products. Fiber optic cables used in hundreds of industries worldwide.
