Dipole Moment of Atom: Key for Material’s Properties
I start it with a simple example of a classroom. As you know, in the classroom when there is no teacher students sit in random directions. While the teacher enters…
Specifications of Different Optical Fibers
Single-mode step-index fiber: Core diameter: 7 to 11 μm Cladding diameter: generally 125 μm Coating diameter: 200 to 300 μm Numerical aperture: 0.08 to 0.15 Performance: 2 to 5 dB/km with a…
Signal Attenuation in an Optical Fiber
Signal attenuation within the optical fibers is usually expressed in the logarithmic unit of the decibel. Decibel is defined by the input and output power ratio of the signal for…
Total Internal Reflection- Optical Fiber
Ray Theory Transmission Let's see what happens when a light ray encounters a boundary separating two different media? In the figure given below, n1 and n2 are the refractive indices…
