Abstract

High numerical aperture multimode fibres for local area applications are presented. Using the MCVD technique with inner pressure control it is possible to dope the core only with Ge02 without cracks along the preform. A maximum value of 27% molar concentration of GeO2 has been achieved. Fibres have been made with nm N.A. greater than 0.3 and with a loss below 4 dB/km at λ= 850 nm and below 1 dB/km at 1300 nm.
