IPC: G02B6/38
Filed: 2001-01-30
Abstract: PROBLEM TO BE SOLVED: To avoid surface damage on an optical ferrule and to accurately butt the end surfaces of a single core optical fiber by inserting the optical ferrule into a split sleeve to an appropriate fitting degree. SOLUTION: A precision split sleeve (20) is manufactured from a pipe (30) made of stainless steel while an inside diameter error is suppressed so that an inside diameter becomes 1.244±0.005 mm. A slit (22) is formed after the pipe is cut and processed, and the inside diameter of the split sleeve is set as the standard combining electrochemical grinding and chemical polishing when necessary. In the case of such precise inside diameter, an optical ferrule (10) with an outer diameter of 1.250 mm is not damaged on its surface by the scraping during insertion, and is reliably held by the sleeve.
