Want this question answered?
unit of dispersion is: (picosecond)/ nanometer kilometer
Dispersion affects optical fibers in the sense that dispersion causes a disruption in the frequency of lights waves and can focus the wavelength nature of light.
Communication in which pulses light travels with its original speed i.e. 3*10^8 m/sec from one place to another with the help of optical fiber,and delay in speed occurs due to reflection,refraction,scattering ,dispersion,macrobending,macrobending and intermodal-dispersion.For any queries contact me: Mudassir Azammudassir.azam537@gmail.com
what is fiber optics what is fiber optics
In Optical Fiber Communication system 1300-1550 nm range wavelengths are used.. Reason for tis s "In this range only we can acheive low attenuation with zero dispersion"
Bandwidth of an optical fiber determines the data rate.
optical bandwidth = 0.707 electrical bandwidth
A: Mostly for mullti channels communication
