Abstract
Deals with an additional source of noise in optical transmission systems. Optical fiber connectors in multimode fiber systems lead to a wavelength dependent attenuation of the transmitted light and hence give rise to mode partition noise if a multimode laser is used. The authors give theoretical estimations of the created excess noise which show that an increase of 25 dB by this modal mode partition noise is possible.
