Wavelength Selection for Single Mode Optical Fibres

Abstract

Wavelength-dependent effects are discussed for a single-mode optical fibre. A specific case is analysed quantitatively to point out the limitations imposed by external factors, like bending & splicing, on the choice of operating wavelength. It is shown that at the wavelength considered optimum from the point of view of minimum intrinsic loss and zero total dispersion, the operation for a graded-index fibre is significantly affected by the loss due to small bending radius in layout and angular misalignment at the splice.
