## Abstract

The present disclosure relates to an optical transceiver module and an active optical cable using the same. The optical transceiver module comprises a lower housing part, a first cassette part seated on the lower housing part and including a first optical connector, a divider insert seated on the first cassette part and coupled to a lower housing part, a second cassette part seated on the divider insert and including a second optical connector, and a upper housing part seated on the second cassette part and coupled to the lower housing part. The divider insert is combined with the lower housing part to form a first insertion hole into which the first optical cable module can be inserted, and the divider insert is combined with the upper housing part to form a second insertion hole into which the second optical cable module can be inserted.

## Claims

### Claim 1

An optical transceiver module, comprising:
a lower housing part;
a first cassette part seated on the lower housing part and including a first optical connector;
a divider insert seated on the first cassette part and coupled to a lower housing part;
a second cassette part seated on the divider insert and including a second optical connector; and
an upper housing part seated on the second cassette part and coupled to the lower housing part,
wherein the divider insert is combined with the lower housing part to form a first insertion hole into which a first optical cable module can be inserted, and
the divider insert is combined with the upper housing part to form a second insertion hole into which a second optical cable module can be inserted.

### Claim 2 (depends on 1)

The optical transceiver module of claim 1, wherein the first cassette part includes a protrusion, and
the lower housing part includes an insertion groove that can be coupled to the protrusion of the first cassette part; and a cassette seating part on which the first cassette part can be seated.

### Claim 3 (depends on 1)

The optical transceiver module of claim 1, wherein the lower housing part includes a fastening screw groove for coupling the divider insert which is inserted into the lower housing part for enabling the second cassette part to be mounted.

### Claim 4 (depends on 1)

The optical transceiver module of claim 1, wherein the divider insert includes a latch, and the lower housing part includes a latch fixing groove in which the latch of divider insert is seated in order to fix the divider insert.

### Claim 5 (depends on 4)

The optical transceiver module of claim 4, wherein the lower housing part includes latch guiding groove for smooth insertion of the divider insert.

### Claim 6 (depends on 1)

The optical transceiver module of claim 1, wherein the second cassette part includes a protrusion, and
the upper housing part includes an insertion groove that can be coupled to the protrusion of the second cassette part and a pressing protrusion for press-fixing an optical fiber of the second cassette part.

### Claim 7 (depends on 1)

The optical transceiver module of claim 1, wherein the upper housing part includes a protrusion to prevent collision and reverse-insertion of the second cassette part.

### Claim 8 (depends on 1)

The optical transceiver module of claim 1, wherein the divider insert includes a latch, and
the upper housing part includes a latch fixing groove on which the latch of the divider insert is seated for fixing the divider insert.

### Claim 9 (depends on 8)

The optical transceiver module of claim 8, wherein the upper housing part includes latch guiding groove for smooth insertion of the divider insert.

### Claim 10 (depends on 1)

The optical transceiver module of claim 1, wherein the first optical cable module includes a third optical connector,
the second optical cable module includes a fourth optical connector,
when the first optical cable module is inserted into the first insertion hole, a surface of the first optical connector and a surface of the third optical connector face each other, so that the first optical cable module is optically coupled, and
when the second optical cable module is inserted into the second insertion hole, a surface of the second optical connector and a surface of the fourth optical connector face each other, so that the second optical cable module is optically coupled.

### Claim 11 (depends on 1)

The optical transceiver module of claim 1, wherein each of the first optical connector and the second optical connector includes:
an optical boundary surface on which light emitted from an optical fiber is incident;
a reflector changing a direction of traveling of light incident through the optical boundary surface; and
a lens emitting light reflected through the reflector outside.

### Claim 12 (depends on 11)

The optical transceiver module of claim 11, wherein the reflector has a cylindrical shape and converts light incident on the reflector into light traveling parallel to a first direction, and
the lens has a cylindrical shape and converts light incident on the lens into light traveling parallel to a second direction which is perpendicular to the first direction.

### Claim 13 (depends on 12)

The optical transceiver module of claim 12, wherein the first direction is perpendicular to both the direction of light incident on the reflector and the direction of reflection.
