## Abstract

An optical connector for optically connecting a first optical waveguide and second optical waveguide, includes a first connector module including a first fixing portion attached to a first board in such a manner that a fixed position is adjustable, a first connecting portion, a first ferrule to which the first optical waveguide is connected, and a guide pin attached to the first ferrule and provided with a tapered portion at a front end; and a second connector module including a second fixing portion fixed to a second board, a second connecting portion connectable to the first connecting portion of the first connector module, a second ferrule to which the second optical waveguide is connected and provided with a fitting hole that fits the guide pin, and a holding unit that movably holds the second ferrule.

## Claims

### Claim 1

An optical connector for optically connecting a first optical waveguide and second optical waveguide, comprising:
a first connector module including
a first fixing portion attached to a first board in such a manner that a fixed position is adjustable,
a first connecting portion,
a first ferrule to which the first optical waveguide is connected, and
a guide pin attached to the first ferrule and provided with a tapered portion at a front end; and
a second connector module including
a second fixing portion fixed to a second board,
a second connecting portion connectable to the first connecting portion of the first connector module,
a second ferrule to which the second optical waveguide is connected and provided with a fitting hole that fits the guide pin, and
a holding unit that movably holds the second ferrule.

### Claim 2 (depends on 1)

The optical connector according to claim 1,
wherein the guide pin is inserted into the first ferrule, in a manner that the guide pin is prevented from pulled out from the first ferrule when the first ferrule is attached to the first connector module.

### Claim 3 (depends on 1)

The optical connector according to claim 1, wherein the holding unit is configured to push the second ferrule toward the first ferrule by a spring.

### Claim 4 (depends on 1)

The optical connector according to claim 1, further comprising: a viewing portion capable of being used for viewing a fitting state of the first ferrule and the second ferrule.

### Claim 5 (depends on 1)

An optical connector system comprising:
the optical connector according to claim 1;
a first optical waveguide connected to the first ferrule of the first connector module; and
a second optical waveguide connected to the second ferrule of the first connector module.

### Claim 6 (depends on 1)

An optical backplane apparatus comprising:
a plurality of the optical connectors according to claim 1;
a plurality of first boards; and
a second board to which the plurality of the first boards are connected via the plurality of the optical connectors, respectively.

### Claim 7

A first connector module comprising:
a first fixing portion attached to a first board in such a manner that a fixed position is adjustable,
a first connecting portion,
a first ferrule to which a first optical waveguide is connected, and
a guide pin attached to the first ferrule and provided with a tapered portion at a front end.
