What is used in optical fiber communication?
WDM wavelength division multiplexing
What are the disadvantages of using optical fiber instead of copper wire for communications?
Optical fiber carries signals through light, and therefore at light speed, the fastest possible, and gets less hot. Copper wire transmits information using electricity, which although fast, is not nearly as fast as light. Fiber optics allows faster transmission of data.
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.
Fiber tract that provides communication between different parts of the same cerebral hemisphere?

What is a fiber tract that provides for communication between different parts of the same cerebral hemisphere?
These are referred to as associational connections when communication is between different parts of cortex in the same hemisphere. There also exists numerous fiber tracts between sub-cortical and cortical structures such as the optic radiation within the same hemisphere.

What is meant by attenuation in Optical Fiber Communication?
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.
Optical communication- may2008 question paper?
what is fiber optics what is fiber optics
Optical signals in optical cables have short wavelength why?
Because the attenuation of the fiber is much less at those wavelengths.
Why bandwidth is more in optical communication?
Bandwidth of an optical fiber determines the data rate.
What are applications of optical fiber?
A: Mostly for mullti channels communication
