Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for making a depressed index cladding for the inner cladding of an optical fiber. SOLUTION: In the method, the depressed index cladding is made by two steps. The innermost portion of the inner cladding is produced by a soot method, thereby deriving the advantages of the soot method for the region of the cladding that carries the most optical power. Thereafter, the remaining portion of the inner cladding layer is formed by using a rod-in-tube step. This method effectively and closely marries the advantages and disadvantages of both methods.
