AT&T PAYS FOR SUMITOMO VPAD OPTICAL FIBRE TECHNOLOGY

By CBR Staff Writer

Sumitomo Electric Corp has decided to transfer its vapour phase axial deposition manufacturing technology for making optical fibre to AT&T Co: the technique was originally developed by Sumitomo jointly with Nippon Telegraph & Telephone Corp and other NTT-tied cable manufacturers, including Furukawa Electric Co; the manufacturing technique is faster and costs less than the MCVD technique currently used by AT&T, which will pay a fixed fee for the technology and says that it will start using it by 1994 at its subsidiary Network Cable Systems in Atlanta, Georgia.
