Discussion has been made on two kinds of sol-gel derived silica-based fibers: fibers drawn from sol-gel derived silica preform and fibers directly drawn from sols. The former fibers can be used as optical fibers and have been developed in that direction. The optical loss of the sol-gel derived fiber has been reduced to 1 dB/km level for pure silica and 10 dB/km level for Ge-doped silica. The latter directly drawn fibers have been developed as heat resistant fibers.
