OPTICAL TRANSCEIVER MODULE HAVING AN EARLY-DISENGAGE DELATCHING MECHANISM

摘要

An optical transceiver module is provided with a delatching mechanism that allows module mounting density to be increased while also providing an ergonomic solution that allows the modules to be easily delatched and extracted from their cages. The delatching mechanism is configured to perform early disengagement of the module housing from the cage by delatching the module housing from the cage after the bail has been rotated to an angle that is less than 90°. Because delatching occurs when the bail has been rotated to a delatching angle that is less than 90°, the modules can be more densely stored with less space between modules that are mounted one above the other than with existing solutions.

主权项

1. An optical transceiver module comprising:
a module housing having at least a first receptacle formed in a front end thereof for receiving a first optical connector of a first optical fiber cable, the module housing having at least a top, a bottom, a first side and a second side; and an early-disengage delatching mechanism secured to the module housing for delatching the module housing from a cage in which the module is stored in a latched state, the delatching mechanism comprising:
a bail having cams disposed on either end;first and second slider arms extending along opposite sides of the module housing; anda yoke having cam followers disposed on either end, the yoke mechanically coupled to proximal ends of the first and second slider arms and to the bail, wherein rotation of the bail away from a latched position causes the cams of the bail to interact with the cam followers of the yoke at the end of a dwell stroke angle that is predetermined in a range between 0° and about 18°, the interaction causing the first and second slider arms to move in a forward direction during early-disengagement of the module housing from the cage.
