What is the actually meaning of attenuation according of ultra sound?
Attenuation refer to the inter mixing of the waves having different frequencies and also known as noise.
What is a good value for dB attenuation?
6 dB is a "good" attenuation.
Light of different colors is different in and?
Wavelength and frequency.(But the product of the [ wavelength x frequency ] of any color is always the same number.)
How do you reduce attenuation effects?
We can reduce attenuation effects bt using repeaters
What is breast attenuation as in nuclear stress test?
breast attenuation correction meethods
Optical signals in optical cables have short wavelength why?
Because the attenuation of the fiber is much less at those wavelengths.
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 are different attenuation factors in optical fiber?
There are three types of attenuation in fibe optics cable. 1). Bending Losses 2). Scattering 3). Absorption
Non-desructive attenuation for attenuation measurement in optical fiber?
Because race car.
Which cable have less attenuation?
optical fiber
Why are waveguides used in high frequency?
I size of the object is comparable to wavelength, it will cause error. In high frequency wavelength is very low. So small-small objects will also cause interference, thereby increasing attenuation. Waveguides are hollow metals. Thus wave does not go out and stay inside. Metals does not cause any attenuation. Propagation of EM wave in waveguide is similar to light in optical fiber.
Can you directly interface two different wavelength fiber optic devices?
If they are tunable, yes you can. If the operating frequency is locked, no, you cannot.
What does UPC in fiber optic mean?
"UPC" its attenuation is smaller than the PC and it has a spherical cross-section
What Is a technology used with fiber optic cable which enables one fiber optic connection to carry multiple light singals simultaneously?
WDM (wavelength division multiplexing)
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 used in optical fiber communication?
WDM wavelength division multiplexing
