Abstract: An optical transceiver module is provided with an elongated delatching pull tab that that enables an optical transceiver module to be easily delatched and pulled from a cage without having to first unplug optical fiber cables from the module and without having to rotate a bail. Thus, the number of manual actions that need to be performed by a user to remove the module from a cage is drastically reduced, which makes simplifies the removal process and makes the design well suited for use in hot-pluggable environments. In addition, the delatching pull tab obviates the need for pins or screws, thereby improving manufacturing yield by reducing the likelihood that the module will be damaged during the manufacturing process. In addition, by eliminating pins or screws and a bail from the design, there are fewer moving parts that can wear out over time.
