What is the Unit for Dispersion in optical fiber?
unit of dispersion is: (picosecond)/ nanometer kilometer
What is the operating frequency of optical fiber?
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"
Does the gauge of fiber optical audio cable affect the audio quality?
No. As long as the signal is getting through, the gauge of the optical connection makes no difference.
How do optical isomers rotate plane of plane polarised light?
REFER : optical rotatory dispersion
Explain the propagation of light through optical fiber and appilication of optical fiber as wave guide and sensor?
The concept of light propagation, the transmission of light along an optical fiber, can be described by two theories. According to the first theory, light is described as a simple ray. This theory is the ray theory, or geometrical optics, approach. The advantage of the ray approach is that you get a clearer picture of the propagation of light along a fiber. The ray theory is used to approximate the light acceptance and guiding properties of optical fibers. According to the second theory, light is described as an electromagnetic wave. This theory is the mode theory, or wave representation, approach. The mode theory describes the behavior of light within an optical fiber. The mode theory is useful in describing the optical fiber properties of absorption, attenuation, and dispersion
What is optical fiber communication?
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 the optical range of optical fiber?
40 GHz
How does an optical transmitter sends signals to the optical fiber?
Usually, there is a laser diode that is optically coupled to the fiber.
Is cross talk is possible in optical fiber?
One of the advantages of optical fiber is that it is NOT susceptible to cross-talk.
Objective type question on optical fiber?
An objective type of question on optical fiber is on that focuses on the integral part of fiber optic. A good question would be, " Why are optical fibers immune to EMI? "
Describe refraction and reflection with respect to Fiber Optical Cable?
Describe refraction and reflection with respect to Fiber Optical Cable?
What are the negative things about fiber optic?
In the fiber optics there are different types of losses; these are the bending loss, absorption loss, dispersion loss, and scattering losses. Bending losses is the loss which exists when an optical fiber undergoes bending, this includes macroscopic and microscopic bending. Absorption loss is the absorption of light energy resulting in dimming of light at the end of the fiber, this includes intrinsic and extrinsic absorption. Dispersion loss is the distortion of the signal as it travels along the fiber optic cable, this includes intermodal and intramodal dispersion. Scattering losses occurs due to microscopic variations in the material density, compositional fluctuations, structural homogeneities and manufacturing defects, this includes linear and non-linear scattering.
