Uses of Optical Fibre

We know that optical fibers are thin glass wires and the primary uses of optical fibers include the transmission of information in the form of light.

Optical fibers are used to transmit data signals over long distances and at high speeds. Extremely soft and transparent fibers are used for optical fibers. Optical fiber works on the basis of total internal reflection. The optical fiber consists of a core, a core and a plastic coating. Optical fiber is most commonly used as an internet cable.

Uses of Optical Fibre

Due to its extremely thin flexibility, it is inserted into cavities in the body and used in various devices to examine internal organs. It is used as a laser during surgery, endoscopy, microscopy and biomedical research.

Advantages of Optical Fiber

  • The density of optical fibers is low
  • Optical fibers are relatively inexpensive
  • Optical fibers protect the data transmitted through them.
  • Optical fibers can carry a lot of data
  • No harmful radiation is emitted by the retinal fibers.

Disadvantages of Optical Fiber

  • It is difficult to connect two optical fibers.
  • Individuals working with optical fibers must be experienced.
  • Initial installation of optical fibers is expensive.
  • Specific tools are needed to analyze light transmission in optical wires.

Uses of Optical Fibre in Daily Life

There are various applications of daily life that depend on optical fibers for their basic functions. Some examples of such applications are given below.

Communication Systems

A fiber optic communication system is a communication system in which information is transmitted as infrared light signal pulses from the source to the destination.

This type of communication is ideal for long distance and short distance communication and allows users to exchange signals of all kinds including voice, video. , data and telemetry signal source, photodetector, and receiver circuit.

Light emitting diodes or lasers are the dominant light sources for fiber optic communication, while PN junction diodes and avalanche diodes are the preferred photodetectors for total reception detection Fiber optic communication systems are preferred over other means of communication.

Because it proves a reliable communication system and provides a low probability of signal interference due to electromagnetic interference, optical fiber based communication systems have very large bandwidth, low probability of signal decay, provide high data protection, are comparatively cost effective and consume less power.

Medical Equipment

Optical fibers are widely used in various medical devices and research laboratory instruments. For example, endoscopes, otoscopes, ophthalmoscopes, etc. are some of the diagnostic medical devices that rely on optical fibers to function normally Optical fibers are often preferred for medical diagnosis and treatment because they cause few or no side effects and present no harm In addition.

to detection and therapeutic applications that release, optical fibers can also be used in applied research in microbiology and biomedical fields.

Fairy Lights

Fairy lights and other decorations also use optical fibers. The advantages of using optical fibers for lighting and decoration include low possibilities of signal leakage and electrocution, low weight, stability, cost, durability and more.

Computer Networking

The interconnection of two or more computer systems in one building or different campuses can be defined as a computer network. These electronic links help users exchange information, access common applications, share resources faster and with greater accuracy and security:

Accuracy It can also be easily improved In addition, physical fibers enable the simultaneous transfer of large amounts of information and data from one end of the network to the other.

Telephone

Local telecommunication connectivity within a building, city or country and global telecommunication connectivity between users in different countries generally depends on the basic functional mechanism of optical fibers. For telecommunication communication, optical fiber cables are joined and placed underground or under part of the telecommunication. sea surface.

This improves security and signal security because streaming data is not easily exposed to electromagnetic interference caused by other naturally traveling magnetic waves.

Optical fiber-based mobile connectivity allows users to interact in fractions of a second while the optical signal flows at the speed of light.

Often eliminates the problem, so that both parties can have a clear conversation with little or no distortion The problem with using optical fibers in telecommunications is that ground distortion often microbends the wire and interferes with signal quality or the content.

Inspection Devices

Optical fibers are very useful for inspection and maintenance engineers. Because fiber optic cables are flexible, they can be used to monitor narrow spaces. The configuration of the monitoring devices varies depending on the type of implementation unit.

For example, a popular optical fiber-based inspection device uses a micro camera mounted on a long flexible optical fiber tube made of silica, plastic or glass. To begin the inspection process, the camera tube arrangement is placed in the area to be inspected.

The camera usually captures visual information and transmits it via a fiber optic cable. The technician or engineer then receives the information on the display device.

Advantages of using fiber optics for diagnostics include greater flexibility, improved visibility, less chance of signal loss or degradation, faster transfer rates and more.
