The question that I am struggling on is:
Signals of wavelength 1.5μm are travelling down a 10km optic fibre. Some travel 'straight down the middle', while others 'zig-zag' back and forth in the fibre. It is required that the maximum phase difference thus caused is no more than 30 degrees. Calculate the maximum path difference allowed.
Could someone please help me out with the steps showing how you got the answer?
