ABSTRACT:
The present invention relates to a single mode optical fibre comprising a first central region having a radius r1, a maximum refractive index value n1and at least one second ring surrounding said first central region, which second ring has a radius r2and a minimum refractive index value n2, wherein n2<n1. The present invention furthermore relates to an optical communication system for multi-channel signal transmission.
