In fiber optics, a weakly guiding fiber is one where the difference between the refractive indexes of the core and the cladding is very small (typically less than 1%).
Famous quotes containing the words weakly, guiding and/or fiber:
“If a weakly mortal is to do anything in the world besides eat the bread thereof, there must be a determined subordination of the whole nature to the one aim—no trifling with time, which is passing, with strength which is only too limited.”
—Beatrice Potter Webb (1858–1943)
“We are born to action; and whatever is capable of suggesting and guiding action has power over us from the first.”
—Charles Horton Cooley (1864–1929)
“I taught school in the early days of my manhood and I think I know something about mothers. There is a thread of aspiration that runs strong in them. It is the fiber that has formed the most unselfish creatures who inhabit this earth. They want three things only; for their children to be fed, to be healthy, and to make the most of themselves.”
—Lyndon Baines Johnson (1908–1973)
