The group delay in a single-mode glass fibre appears to be dominated by the glass dispersion but could, in principle, be reduced considerably by using glass with a certain index/frequency characteristic. In a fibre communication system, with a GaAs laser as transmitter, the large frequency spread of the present-day laser is the most serious factor limiting the bandwidth.
