  • Optical transmission system comprising a monomode optical transmission fibre having a tapered end portion
    Patent number: 4721353
    Abstract: An optical transmission system comprises a monomode optical transmission fibre which has an end portion in which the diameter of the core tapers toward 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 the lens arranged in front of or on the fibre. This yields a higher coupling efficiency.
