Fiber Optics Compute the single mode cutoff wavelength Core

Fiber Optics: Compute the single mode cutoff wavelength.

Core Diameter = 8.2 m

Numerical Aperture (NA) = 0.14

Solution

Cut off Wavalength <= 1260 nm for Diameter= 8.2 um, NA = 0.14

Its a syandard cut off wavelength for Corning SMF-28 optical fibre we need more data to compute the wavelength
