Abstract :
Design considerations are discussed for the structural optimisation of 1.3μm zero-dispersion single-mode fibres for use in the 1.55 μm-wavelength region. The ranges of optimum fibre parameters for mode field diameter 1W and effective cutoff wavelength λce are determined as 2W = 10.5 ± 10 μm and 1.35 μm ± λce ± 1.60 μm, respectively. A mean test fibre loss of 0.185 dB/km has been achieved.
