What are the disadvantages microwave communication?
attenuation due to atmospheric conditions.
What is the difference between step index and graded index optical fiber?
1. Step index fiber is of two types viz; mono mode fiber and multi mode fiber. Graded index fiber is of only of one type that is multi mode fiber. 2. The refractive index of the core of the step index fiber is constant through out the core. The refractive index of the core of the graded index fiber is maximum at the center of the core and then it decreases towards core-cladding interface. 3. Number of modes for step index fiber N = V2/2, where V is cut off frequency or normalized frequency or V- number Number of modes for graded index fiber is N = V2/ 4. 4. V number can be less that 2.405 or more that 2.405 for step index fiber V number is always more than 2.405 for graded index fiber. 5. Step Index Fiber is a fiber in which the core is of a uniform refractive index and there is a sharp decrease in the index of refraction at the cladding. Graded Index Fiber is a type of fiber where the refractive index of the core is lower toward the outside of the fiber. It bends the rays inward and also allows them to travel faster in the lower index of refraction region. This type of fiber provides high bandwidth capabilities.
Who does the voice over for the Fiber One commercials?
I'm not which Fiber 1 commercial you are referring to, but sometimes I swear it is Robert De Niro
What fiber did dupont make?
Nylon and Lycra.
A fiber tract that provides for communication between the cerebrum and the CNS area?
If the fiber tract connects the cerebral cortex and the lower brain or spinal cord then it is referred to as a projection tract.
Non-desructive attenuation for attenuation measurement in optical fiber?
Because race car.
Which cable have less attenuation?
optical fiber
What are different attenuation factors in optical fiber?
There are three types of attenuation in fibe optics cable. 1). Bending Losses 2). Scattering 3). Absorption
What is meant by attenuation in optical fiber?
When an optical signal of a given wavelength travels in the fiber it looses power. The amount of loss of power per Km length of fiber is called its attenuation. A=10*LOG10(POUT/PIN) dB/Km Where POuT is optical power after 1 Km PIN is th epower launched in the Fiber.

What does UPC in fiber optic mean?
"UPC" its attenuation is smaller than the PC and it has a spherical cross-section
Optical signals in optical cables have short wavelength why?
Because the attenuation of the fiber is much less at those wavelengths.
Why are infrared waves used in fiber optics?
This is because infrared can travel farther with less distortion, i.e., it has less attenuation.
What is meant by atenuation in fiber optics?
Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
Does attenuation happen when EM wave travels in space?
There is no attenuation due to absorption, but attenuation will occur due to divergence (spreading out) of the wave.
What is a good value for dB attenuation?
6 dB is a "good" attenuation.
What causes diverticulosis?
Constipation or Apendicitis
