Consider a step index single mode fiber with a length of 100km. The core index being 1.46, and the cladding index 1.45 and a loss of .20dB/km at a wavelength of 1550nm. The dispersion coeffcient of this fiber at 1550nm is D = 1.5. For a high speed data with .8nm spectral width what is the group velocity delay?

3- Consider a bare fiber consisting of core of refractive index 1.48 and having air as cladding What is its NA? What is the maximum incident angle up to which light can be guided by the fiber? 4- Consider a fiber from which cladding is removed over a short length as shown below. Assume that the core and cladding refractive indices are 1.5 and 1.4 respectively, What ill happen to the output power if the bare portion of the fiber...
