W Opt. Fiber Comm. Systems By Lec. Ansam Mohammed Homework: Two step fiber exhibits the following parameters: a. A multimode fiber wore a core refractive index of 1.5, a relative refractive index difference of 3% and an operating wavelength of 0.82 um. b. An 0.8 um core diameter single mode fiber with a core refractive index the same as in (a), a relative refractive index difference of 0.3% and an operating wavelength of 1.55 um. Estimate the critical radius of curvature at which large bending losses occur in both cases. W Opt. Fiber Comm. Systems By Lec.
