## Abstract

An optical transceiver easily set within the cage of the host system. The optical transceiver of an embodiment provides a finger surrounding the housing of the optical transceiver. The finger has an rear edge, whose tip is bent downward so as to be received in the first groove of the housing, extending diagonally to the brim of the cage; and a reinforced portion with a U-shaped cross section tightly set within the second groove of the housing.

## Claims

### Claim 1

An optical transceiver comprising:
an optical subassembly for converting a signal between an electrical form and an optical form; and
a housing including a top cover and a bottom frame to form a space to enclose the optical subassembly therein, the top cover providing a pocket in one of longitudinal ends thereof and an inclined surface, the bottom frame providing a projection and a pair of sides, the projection being set within the pocket of the top cover by sliding on the inclined surface, the sliding on the inclined surface widening a space between the sides,
wherein the top cover is fitted in the bottom frame.

### Claim 2 (depends on 1)

The optical transceiver of claim 1,
wherein the top cover provides a tab in one of longitudinal ends thereof and the bottom frame provides a beam extending laterally of the optical transceiver, the beam providing a pocket for receiving the tab of the top cover,
wherein the top cover pivotally rotates around a tip of the tab.

### Claim 3 (depends on 1)

The optical transceiver of claim 1,
wherein the sides of the bottom frame each has a top thereof closely contact with the top cover.

### Claim 4 (depends on 1)

The optical transceiver of claim 1,
wherein the top cover provides a terrace in one of longitudinal ends thereof,
wherein the pocket and the inclined surface are formed in the terrace.

### Claim 5 (depends on 4)

The optical transceiver of claim 4,
wherein the bottom frame further provides a bottom facing the top cover,
wherein the bottom in a portion facing the terrace is removed.
