Optical connector and connection method of optical connector

Abstract

The invention relates to an optical connector and a connection method of the optical connector. When the connection end surfaces of the ferrule are butted against each other, if the ferrule does not deviate up and down by an estimated amount, the connection loss of the optical fiber increases. An optical connector according to the present invention includes: a ferrule having a guide pin hole, a plurality of optical fiber holes arranged in a width direction, and an inclined end surface; and a housing that presses and accommodates the ferrule in a retractable manner. It has a biasing portion, and when the direction perpendicular to the connector attaching and detaching direction and the above-mentioned width direction is defined as the vertical direction, and the side of the above-mentioned inclined end surface that protrudes toward the counterpart connector side is defined as the upper side, when the direction is perpendicular to the above-mentioned counterpart connector When the connector is connected, the urging portion applies an upward force to the ferrule.

Description

technical field [0001] The invention relates to an optical connector and a connection method of the optical connector. Background technique [0002] As an example of an optical connector, for example, an MPO connector (F13 type multi-core optical fiber connector specified in JIS C5982) is known. In this MPO connector, the connection end surface of the ferrule may be obliquely ground. In Patent Document 1, it is described that when the connection end faces of the obliquely ground ferrules are butted against each other, each ferrule is displaced vertically due to the gap between the alignment guide pin and the guide pin hole of the ferrule. shift, resulting in an axis offset of the fiber. In addition, Patent Document 1 describes that in order to suppress an increase in optical loss caused by such an optical fiber axis misalignment (positional misalignment between the cores of the optical fibers), the vertical deviation of the ferrule is estimated in advance. amount, and set...

AI Technical Summary

Problems solved by technology

However, since the fiber hole of the ferrule is installed at a position where the amount of vertical shift of the ferrule is estimated in advance, if the ferrule is not shifted vertically by about the estimated amount, the connection loss of the optical fiber will be reduced. increase

In addition, if the vertical deviation of the ferrule varies every time the optical connector is attached or detached, the connection loss to the optical fiber will vary, making it difficult to achieve low loss stably.
