Low-loss quadruple-clad single-mode lightguides with dispersion below 2 ps/km nm over the 1.28 μm–1.65 μm wavelength range

Abstract

Low-loss fibres with dispersion below 2 ps/km nm over the spectral range between 1.28 μm and 1.65 μm have been designed and fabricated. These fibres were achieved by the use of quadruple cladding and designed with the use of a computer analysis program. They should be desirable for future wavelength-division-multiplexing applications.
