Abstract

1496324 Graded-index optical fibre INTERNATIONAL STANDARD ELECTRIC CORP 11 Nov 1976 [14 Nov 1975] 46973/76 Heading G2J To establish an effective r.i. gradient radially of the core of the fibre use is made of allimative annuli of two materials having differing r.i. and the chosen law is achieved by correlating the thicknesses of the various annuli.
