ABSTRACT:
A method is disclosed for producing optical fibers which are drawn with diameter variations in the transmitting core but with uniform overall diameter. In this process the glass starting member used in fabricating the optical fiber preform is etched with appropriate grooves. Additional glass is subsequently deposited on the etched starting member, and a fiber is drawn from the preform so fabricated.
