Abstract

In a relay optical connector 1, a part 16 of a ferrule 4 is butted against a part 17 of a ferrule 5 in a ferrule end face 14 of the ferrule 4 in which an optical fiber 2 for an optical connection is exposed and a ferrule end face 15 of the ferrule 5 in which an optical fiber 3 is exposed and the one optical fiber 2 and the other optical fiber 3 are arranged so as not to come into contact with each other. Specifically, one of the ferrule end faces 14 and 15 is surface-ground so as to extend along a surface at right angles to an optical axis L and the other thereof is diagonally surface-ground so as to be inclined at a prescribed angle θ relative to the surface at right angles to the optical axis.

Claims

1. A relay optical connector, comprising:

one optical propagation member for an optical connection;

other optical propagation member;

a first member having a first end face on which the one optical propagation member is exposed; and

a second member having a second end face on which the other optical propagation member is exposed;

wherein a part of the first member in the first end face of the first member is butted against a part of the second member in the second end face of the second member and the one optical propagation member and the other optical propagation member are arranged so as not to come into contact with each other.

2. The relay optical connector according to claim 1, wherein one of the first end face and the second end face is surface-ground so as to extend along a surface at right angles to an optical axis and the other thereof is diagonally surface-ground so as to be inclined at a prescribed angle relative to the surface at right angles to the optical axis.

3. The relay optical connector according to claim 1, wherein one of the first member and the second member is urged toward the other.
