D. modal dispersion, Fiber optic connections suffer high loss due The different wavelength components of a pulse will see a different index and travel at different speeds, causing the pulse to spread. If no loss is found, then most probably there is dispersion with that particular wavelength. EDC solution has the ability to automatically adjust the filter weights according to the characteristics of the received signal, which is known as adaptation. The highest profile of these factors is four-wave mixing, which led to the development of non-zero dispersion-shifted fibers (NZDF).

Which of the following method determines the dispersion limitation of an optical link? m C. Vertical cavity surface emitting (VCSEL) Waveguide dispersion occurs due to dependence of the mode propagation constant on the fiber parameters (core radius, and difference between refractive indexes in fiber core and fiber cladding) and signal wavelength. Modal dispersion occurs because the optical path length varies with each mode, as shown in Figure 3. Modal dispersion is a distortion mechanism occurring in multimode fibers and other waveguides, in which the signal is spread in time because the propagation velocity of the optical signal is not the same for all modes.
