## Abstract

An optical communication module includes a lens unit and an optical-electrical converter. The optical-electrical converter includes a circuit board and the lens unit is fixed on the circuit board. The lens unit has an extension portion, and the extension portion extends outwards from the lens unit and is parallel to the circuit board. Glue is located between the extension portion and the circuit board to secure the lens unit on the circuit board.

## Claims

### Claim 1

An optical communication module, comprising:
an optical-electrical converter, comprising a circuit board;
a lens unit comprising at least one extension portion, the least one extension portion extending outwards from the lens unit and being substantively parallel with the circuit board; and
glue coated between the at least one extension portion and the circuit board to secure the lens unit on the circuit board.

### Claim 2 (depends on 1)

The optical communication module of claim 1, wherein the circuit board is selected from the group consisting of hard circuit board and flexible circuit board.

### Claim 3 (depends on 1)

The optical communication module of claim 1, wherein the optical-electrical converter comprises light emitting diodes and photo diodes.

### Claim 4 (depends on 3)

The optical communication module of claim 3, wherein the lens unit comprises lenses, and the lenses are arranged on a surface of the lens unit facing to the circuit board and are configured for coupling with the light emitting diodes and the photo diodes.

### Claim 5 (depends on 4)

The optical communication module of claim 4, wherein the lens unit comprises a reflecting surface.

### Claim 6 (depends on 5)

The optical communication module of claim 5, wherein an included angle between the reflecting surface and the circuit board is 45 degrees.

### Claim 7 (depends on 5)

The optical communication module of claim 5, wherein an included angle between the reflecting surface and an optical axis of each of the lenses is 45 degrees.

### Claim 8 (depends on 1)

The optical communication module of claim 1, wherein the lens unit comprises four surfaces perpendicular to the circuit board, the at least one extension portion comprises four extension portions, and each of the four extension portions extends outwards from a respective one of the four surfaces.
