Task 3th 1. –        What are the energies in electron volts (eV) of light at wavelength 850, 1310, 1490, 1550 nano meters? –        Consider A 1-nano second pulse with a 100 nW amplitube at ecah of these wavelengths. How many Photons are in such a puls at each wavelengths? 2. Three sine wave have the

The graph of relation betwen Numerical Aperture and V parameters. V parameter determines the mode transmited by the fiber. If the V parameter is less than 2,405 (or the same), it means that the fiber transmits a single mode.The calculation uses microsoft office.

In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes the range of angles over which the system can accept or emit light. By incorporating index of refraction in its definition, NA has the property that it is constant for a beam as it goes from one material to
