  • Non-intrusive fibre optic tap
    Patent number: 4898442
    Abstract: A ribbed structure (60a), co-operating with an unribbed surface of a coupling element 64, is employed to introduce microbending in an optical fibre (51) intermediate its two ends with a periodicity which couples the fundamental bound mode of the fibre into a cladding mode from which optical power is tapped into the optical coupling element (64) provided with a conical reflecting surface (63a) for collimating the extracted light. Light injection is achieved by a reciprocal process using a ribbed structure (60b) and a conical reflecting surface 63b.
