Abstract :
Dispersion sensitivity due to small core radius changes for infra-red dispersion-shifted fibres with various alpha -index profiles is investigated. It is shown that the dispersion sensitivity decreases as alpha decreases. Moreover, the bending sensitivity is also described and fibre parameters suitable for fully utilising the low intrinsic loss are summarised.
