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.
