## Abstract

To provide an optical connector which enables suppression of crosstalk, an optical connector includes a housing, an optic transceiver and a lens body, wherein the lens body includes a light emitting side lens section configured to be interposed between a light emitting element and one optical fiber of a partner optical connector, a light receiving side lens section configured to be interposed between a light receiving element and another optical fiber of the partner optical connector, and a light receiving side lens surrounding section in an integrated manner. A light shield section is formed in the lens body, the light shield section being configured to suppress a portion of light emitted from the light emitting element which enters the light receiving element via the lens body. The light receiving side lens surrounding section is configured to be transparent at an end facing the partner optical connector.

## Claims

### Claim 1

An optical connector comprising:
a housing;
an optic transceiver with a light emitting element and a light receiving element, the optic transceiver being accommodated in the housing; and
a lens body accommodated in the housing, the lens body being configured to be interposed between a partner optical connector and the optic transceiver,
wherein the lens body includes, in an integrated manner:
a light emitting side lens section configured to be interposed between the light emitting element and one optical fiber of the partner optical connector;
a light receiving side lens section configured to be interposed between the light receiving element and another optical fiber of the partner optical connector; and
a light receiving side lens surrounding section with a tubular shape, the light receiving side lens surrounding section surrounding the light receiving side lens section,
wherein a light shield section is formed in a section of the lens body which connects the light emitting side lens section to the light receiving side lens section,
wherein an end of the light receiving side lens surrounding section facing the partner optical connector is configured to be transparent, and
wherein the lens body comprises a light emitting side lens surrounding section with a tubular shape which surrounds the light emitting side lens section, the light emitting side lens surrounding section being formed from black resin.

### Claim 2 (depends on 1)

The optical connector according to claim 1,
wherein the light receiving side lens surrounding section intersects an outer edge of an optical fiber opposing surface of the light receiving side lens section at an intersection portion, and
wherein the end of the light receiving side lens surrounding section facing the partner optical connector extends from a portion of the light receiving side lens surrounding section which is slightly closer to the optic transceiver than the intersection portion, to an end face of the light receiving side lens surrounding section facing the partner optical connector.
