Benefits of technology

[0019] By this production method, the portions where the mode field diameter is enlarged in the optical fibers are inserted into the fiber holes of the optical splice member. For this reason, where two optical fibers are brought into a face-to-face state in each fiber hole, the optical fibers can be spliced with each other with

Problems solved by technology

In consequence, a splice loss will be large

Abstract

An optical splicer 2 according to an embodiment of the present invention has a plurality of optical fibers 6, and an optical splice member 8 having a plurality of fiber holes 14 in each of which a portion including one end 6a of each fiber 6 is inserted, and a mode field diameter W1 in one end 6a of optical fiber 6 is enlarged relative to a mode field diameter W2 in the other portion of optical fiber 6.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an optical splicer for splicing optical fibers, an optical module, and a method of producing the optical splicer. [0003] 2. Related Background of the Invention [0004] There are optical splicers for splicing optical fibers by inserting the optical fibers in glass capillaries face to face. [0005] For example, Japanese Patent No. 3154230 describes the optical splicer for splicing a plurality of optical fibers, which comprises a plurality of glass capillaries. In this optical splicer, the central region of each glass capillary is preliminarily filled with an index matching agent. [0006] Japanese Patent Publication No. 7-50219 describes the optical splicer in which a predetermined space is provided between end faces of face-to-face optical fibers and in which the space is filled with an elastic adhesive to effect a splice of the optical fibers. SUMMARY OF THE INVENTION [0007] In the afore...
