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.
Distance is nothing but a clear demarcation of angle which the distant object makes with an eye of the observer.
There are many different classifications. Each one is meant to reach the target audience in a different way to sell more products.
In "National Treasure," the lantern was meant to warn Paul Revere of the British troops' approach during the American Revolution. Specifically, it was used to signal whether the British were coming by land or by sea, with one lantern for land and two for sea. This historical context is woven into the film's treasure hunt, illustrating the importance of communication and secrecy in the fight for independence.
what is meant by speed
do you mean star, or act? if you meant star, no. i dont know the answer if you meant act.

Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
An optical modes refer to a specific solution of the Wave Equation which satiates the boundary conditions.

Not real
horizontal communication
Acoustic impedance is the measurement that indicates how much sound pressure the vibration of molecules at a given frequency is generated. Attenuation refers to the gradual loss in intensity through a medium, such as light and sound in water.
Communication is written for a specific purpose and audience; an example of communication that is meant to help consumers is product sensitization.
Signal repeaters are generally used in the telecommunication and electronics industries. There can be passive radio signal repeaters, multi-port repeaters, optical signal repeaters for optical fiber and digipeaters which repeat packet data.
communication that was not directly meant to be communicated
No
i know but they are asking to me i
