Optical transmission system comprising a monomode optical transmission fibre having a tapered end portion.

摘要

An optical transmission system comprises a monomode optical transmission fibre which has an end portion in which the diameter of the core tapers towards the end. If the tapered portion is followed by a part of increasing diameter this results in a better matching to the wavefront which issues from a lens arranged in front of or on the fibre. This yields a higher coupling ef­ficiency.
