What are the important blocks of point to point links in optical communication.?
In optical communication, important blocks of point-to-point links include the light source (typically a laser), which generates the optical signal; the optical fiber, which transmits the signal over distances; and the photodetector, which converts the received optical signal back into electrical form. Additional components may include amplifiers to boost signal strength, multiplexers and demultiplexers for combining and separating multiple signals, and various types of connectors and splices for ensuring effective signal transmission. These elements work together to ensure efficient and reliable communication over optical networks.
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.

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.
What type of Electromagnetic radiation used in optical fiber communication?
Optical fiber communication primarily uses infrared light as the type of electromagnetic radiation. This is because infrared light has a longer wavelength that is well-suited for transmitting data over long distances through optical fibers with minimal signal loss.

Optical signals in optical cables have short wavelength why?
Because the attenuation of the fiber is much less at those wavelengths.

What do the LX stand for in fiber optic?
In fiber optics, "LX" stands for "Long Wavelength." It refers to a standard for optical transceivers that operate at a wavelength of 1310 nanometers, which allows for longer transmission distances compared to shorter wavelengths. LX transceivers are commonly used in networks for data communication over multimode or single-mode fiber, typically supporting distances up to 10 kilometers.
