Abstract

A pluggable optical transceiver implementing a pull-tab is disclosed. The pull-tab includes arms assembled with a body of the optical transceiver and a holder connecting the arms. The holder, which is provided in ends of the arms, provides a tab and a bridge, where the tab and the bridge form a space where an optical fiber mated with the optical transceiver is secured. The tab is dynamically engaged with the bridge after the optical fiber is set on the bridge.

First claim

I claim:

1. An optical transceiver capable of electrically communicating with a host system as engaged within a cage prepared in the host system, comprising:
a body having an optical receptacle in an end thereof and an electrical plug that communicates with the host system in another end opposite to the end, the optical receptacle receiving an optical fiber;
a pair of sliders provided in respective sides of the body, the slider releasing the engagement of the optical transceiver with the cage; and
a pull-tab having a pair of arms and a holder, the arms in one of ends thereof being assembled with the sliders and co-operating therewith, the holder providing a bridge and a tab that includes two bent portions and a linear portion, the bridge connecting the arms at another of ends thereof, one of the bent portions extending from one of the arms, the linear portion connecting the two bent portions, the other one of the bent portions providing a projection, the other one of the arms providing a hook with an opening in an end thereof, the projection being engaged with the opening of the hook,
wherein the linear portion of the tab makes a distance against the bridge that is shorter than a diameter of the optical fiber when the projection provided in the other one of the bent portions engages with the opening in the end of the other one of the arms and no fiber is held in the holder, thereby the holder securely holds the optical fiber received in the optical receptacle in front of the optical receptacle.

2. The optical transceiver of claim 1 ,
wherein the bridge includes a hollow, and
wherein the linear portion, the bent portions, and the hollow form a circular space extending towards the bent portions, the circular space securing the optical fiber therein.

3. The optical transceiver of claim 1 ,
wherein the hook traces an outer shape of the other one of the bent portions of the tab.

4. The optical transceiver of claim 1 ,
wherein the tab has an edge in an outer side apart from the optical receptacle and the bridge has another edge in the side apart from the optical receptacle, the edge of the tab being offset from the another edge of the bridge along a direction the optical fiber extends.

5. The optical transceiver of claim 4 ,
wherein the edge of the tab is far from the optical receptacle compared with the another edge.

6. The optical transceiver of claim 1 ,
wherein the pull-tab is made of resin.

7. The optical transceiver of claim 1 ,
wherein the optical transceiver includes a transmitting fiber that carries an optical signal outgoing from the optical transceiver and a receiving fiber that carries another optical signal incoming to the optical transceiver.

8. The optical transceiver of claim 1 ,
wherein the arms extend from respective sides of the body.
