Solution:

Advantages of Fibber Optic Sensors:

• An optical fiber cable is much smaller than a copper wire line. This feature of small size and light weight is especially important for underwater cables and overcrowded transmission lines.

• They are compatible with fiber optic communication systems in case data is being transmitted through the aforesaid medium.

• They do not conduct any electric current and, therefore, optical fiber sensors are very useful in explosive environments and in high voltage equipment.

• Optical fiber cables can offer more channels than co-axial cables.

• Optical fibers are fabricated from electrical insulators and hence can be used in electrically hazardous environments as the fibers create no arcing or spark hazard at abrasions or short circuits.

• They are immune to electromagnetic interference and radiated signals. Optical fiber does not pick up radio frequency interference, em interference, or switching surges produced by nearby electrical machines and other sources of potential electrical noise and increases the security of data transmission.

• Therefore, the output of optical fiber sensors is free from the noise of any type.

• The cost of optical fiber cable and its installation is easier than its metal. counterpart. The transmission loss of fiber is small.
