OPTICAL FIBER CONNECTOR AND OPTICAL COUPLING ELEMENT

摘要

PROBLEM TO BE SOLVED: To improve the working efficiency of processing and assembling of an optical fiber connector to reduce the cost by forming V-groove position for fixing optical fibers and V-groove portions for guiding the front ends of these optical fibers by making their bottoms common. SOLUTION: The fixing part V-grooves 11b of a depth to the extent that the upper part of bare fibers partly protrude are formed on the fixing part surfaces 14 in the front part of an optical fiber fixing substrate 10. The upper parts thereof press and join the partly protruding bare optical fibers by using a fixing part upper plate 30, thereby positioning and aligning the bare optical fibers. Guide part surfaces 13 are formed at a high position via a step part 13c to the fixing part surfaces 14. The fixing part V-grooves 11b and the guide part V-groves 11a making their bottoms common and having the depth and width at which the bare optical fibers can be housed without protruding their upper parts are formed at the guide part surfaces 13. A guide part upper plate 20 is adhered and fixed to the front portion on the guide part surfaces 13.
