  • Plastics packaged optical fibre and method of making same
    Patent number: 5444808
    Abstract: An optical fibre, comprising a glass core 10 surrounded by a glass cladding (11) of lower refractive index, is provided with inner and outer relatively high modulus plastics layers (12 and 14) spaced apart by a relatively low modulus layer 13. The low modulus layer is applied from an aqueous dispersion, and is dried but not sintered. This leaves the layer (13) in a form in which it has little adherence to the underlying inner plastics layer (12), thereby enabling the outer layer (14) to be readily peeled by mechanical means.
    Type: Grant
    Filed: June 3, 1994
    Date of Patent: August 22, 1995
    Assignee: Northern Telecom Limited
    Inventors: Nigel Shackleton, Laura E. Pears
