Reconstructed silica made from porous glass is used to fabricate doped multimode optical fibres. This process constitutes an alternative to the more classical Modified Chemical Vapour Deposition (MCVD) process when used in conjunction with solution doping. Comparison between porous glass and porous silica soot obtained from MCVD allows to highlight the advantages and disadvantages of both methods. The reconstructed glass process has been used to develop a multimode high attenuation optical fibre (HAF) working at 850nm.
