40GBASE-SR4 Frame Error Rate Test of Chromatic Dispersion Compensating MMF

On the precision of mode delays derivation with the use of the WKB method

“…However, due to the so called profile dispersion, this is possible only in a very narrow wavelength range. In addition, several studies indicate (Qiu et al 2013;Molin et al 2011) that in fibers of the latest generation (like OM4) it is the chromatic dispersion that becomes the dominating source of intersymbol interference, as opposed to modal dispersion, which was regarded as the dominating distortion source for many years.…”
