Fiber attenuation, which is also called signal loss or fiber loss, is the consequence of the intrinsic properties of an optical fiber (multimode and single mode fiber). The classification of optical fiber can be done based on the materials used, refractive index, & mode of propagation light. Their first fibres had attenuations of 5 decibels (dB), i.e. They are characterized by the way light travels down the fiber and depend on both the wavelength of the light and the mechanical geometry of the fiber. Apart from the intrinsic fiber losses, there are some other types of losses in the optical fiber that contribute to the link loss, such as splicing, patch connections, bending, etc. The use of optical fibres has genuinely proved to be beneficial compared to the traditional use of metallic wires. 3. Examples would include connections from receivers to equipment pigtails, or normal termination, or when re-configuring systems. Fibre‐optical microendoscopy takes advantages in imaging of freely moving animals, long‐term imaging, minimally invasive diagnostics, and microsurgery. Fiber optic splicing is another type of loss in optical fiber. All incident rays will get internally reflected. Hence, based on the differences in the structure of the core, there are three main types of optical fibers. That is to say that the diameter of the core is essentially of the same order as the wavelength of the light passing through it. 2. In microstructured optical fibers, the physical structure of the waveguide is used at a nano-scale level to manipulate light.
