The fields in which we can use Optical fiber cables for better transmission

Optical fiber, thin flexible fiber with a glass core via which light signals can be sent with minute loss of strength. This Optical fiber is also transparent. Optical fibers are mostly used in transmit light between the two ends of the fiber and find wide usage in fiber-optic communication. Here they permit transmission over longer distances and at higher data rates than electrical cables. Fibers are used instead of metal wires because signals travel along with them with less in addition. Optical fibers are also used for illumination and imaging. These fibers typically include a core surrounded by a transparent cladding material with a lower index of refraction.

Uses of Optical Fibers in various fields:

Communication:- 

1. Used as a medium for telecommunication and computer networking because it is flexible and can be bundled as cables. 
2. Advantageous for long-distance communications. 
3. This fiber can carry many independent channels, each using a different wavelength of light. 

Sensors:- 

1. Optical fiber is used to connect a non-fiber optic sensor to a measurement system. 
2. These fibers are used as a sensor to measure strain, temperature, and pressure. 

Power transmission:

1. It can be used to transmit power using a photovoltaic cell.
2. It is especially useful for MRI machines, which produce strong magnetic fields.

Miscellaneous uses:

1. Used in imaging optics.
2. Light guides as medical and other applications where bright light needs.
   

Fibers that support many propagation paths are called Multi-mode optical fiber. Multimode optical fiber is way more powerful than the single- mode. A multi-mode cable has a much larger central core that allows a greater amount of light to travel through it at once. The core of a multi-mode cable is varied but usually, it is 50/125 or 62.5/125 microns in size. Increased core size means the light can refract at a greater rate.

Some of the Benefits of Fiber Optic cable:

1. Optical fiber has a number of cores generally one core is used for transmission and another core is used for reception.
2. Fiber optic cables have a much greater bandwidth than metal cables.
3. Optical fiber can provide data transmission performance up to 10 Gbps. 

Specific Applications:

1. Fibers are widely used in illumination application.
2. They are used as a light guides in medical and other applications in some building.
3. Fibers can use to route sunlight from the roof to another parts of the building.

Multimode Optical Fiber cables are extremely useful and are the primary thing of the fiber-optic networks. This type of cable is generally used for a short distance.

WPI’s Fiber optic cable is the only certified cable available in the market. It captures the low-level light events. The transmission percentage in this cable is so consistent and that it gives us the desired perfect result.

Fiber with a core diameter less than about ten times the wavelength cannot be modeled using geometric optics. It must be analyzed as an electromagnetic structure. The electromagnetic analysis may also be required to understand behaviors that occur when coherent light propagates in multi-mode fiber.  The fiber supports one or more confined modes by which light can propagate along the fiber. Fiber supporting only one mode is called single-mode -fiber. The behavior of multi-mode fiber can also be modeled using the wave equation.  If the fiber core is large it can support more than a few modes.
