Abstract
An optical 1.times.N star coupler has a single mode input fibre (I) and N single mode output fibres (O.sub.1) forming an output fibre assembly. The output fibres (O) are tapered within a former (2) which holds each output fibre (O) so it is positioned substantially identically relative to the remaining output fibres. The input fibre (I) is also tapered such that the fundamental mode field of the input fibre (I) and output fibre assembly are substantially equal. The identical relative positions of the output fibres (O) provides a wavelength independent 1.times.N star coupler.
