Abstract

A pluggable optical transceiver is disclosed. The optical transceiver provides a pull-tab assembled with a body of the transceiver. The pull-tab comprises a pair of arms and a handle. The arms in an end portion thereof each provides a leg set in a guide formed in the body. Sliding the pull-tab to disengage the optical transceiver from the cage, the leg is slid within the guide to push the end portion of the arm outwardly. The handle provides in an end thereof a bar including a slope. The optical fiber pulled out from the optical connector set in the optical receptacle of the transceiver rides on the slope even when the transceiver is set in the cage by the upside-down arrangement.

First claim

1 .- 10 . (canceled)

11 . An optical transceiver to be inserted in a cage prepared in a host system, the cage providing a stopper to prevent the optical transceiver from sliding out therefrom, the optical transceiver comprising:
a housing configured to enclose an optical component and an electrical component therein; an optical receptacle to receive an external optical connector therein; and a pull-tab including a handle having a pair of extensions and a bar connecting the extensions, the bar including a supporting slope to support an optical fiber extending from the optical connector set in the optical receptacle.

12 . The optical transceiver of claim 11 ,
wherein the supporting slope supports the optical fiber when the optical transceiver is set in the cage by an upside-down arrangement.

13 . The optical transceiver of claim 11 ,
wherein the bar further provides walls in respective sides thereof, the walls and supporting slope forming a hollow to secure the optical fiber therein.

14 . The optical transceiver of claim 11 ,
wherein the bar provides a front end thereof formed in an arched shapes.

15 . The optical transceiver of claim 11 ,
wherein the optical fiber is secured with a boot from an end of the external optical connector, and wherein the boot in an end thereof, the supporting slope in an end closest to the optical transceiver, and another end farthest from the optical transceiver virtually form an arch with a radius of curvature greater than 30 mm.
