Do fibers have losses?
Everything in the universe is inefficient. It means that while a measured amount of something enters in a system, less comes out than initially went in. When you pour a liter of water in one end of a pipe, then you will always find less than a liter out of the other end. When you apply a voltage to the extreme of one wire, it doesn't matter how you do this, you will find a lesser value at the other end.
Fiber optics are no exception that the light entering one end encounters all types of obstacles and flaws, which are resulting in losses; from 2 to 10 percent for every running meter.

calculate the work required to be done to stop a car of 1500 kg moving at a velocity of 60 km/h?
why The magnitude of known potential difference must be greater than the value of unknown potential difference to be measured.
In an electric field a charge (Q) experiences a force F = QE. If charge is positive then force is directed in the direction of field whereas if charge is negative force acts on i
