Embodiment Construction

[0018] The present invention is directed to an optical communication module having a latch / unlock mechanism that overcomes the aforementioned disadvantages and provides other advantages. By partially enclosing the slider arm inside the module housing, the aforementioned problem of the slider arm coming into contact with the cage's EMI gasket and potentially damaging the gasket is prevented. In this way, the slider arms do not come into contact with the cage when the module housing is inserted into and withdrawn from said cage. The distal portion of the slider arm on which the hook feature is formed remains outside the module housing to allow it to make contact with the cage latch during unlocking. Additionally, partially enclosing the slider arms within the module housing provides greater rigidity to the latch / unlock mechanism and eliminates the need for the latch / unlock mechanism to apply excessive force to the cage when attempting to extract the module from the cage. The po...

Abstract

The application relates to an insertable optical communication module having an improved latch / unlocking mechanism and an optical communication assembly comprising the module. A slider arm of the latch / unlocking mechanism is partially packed into a housing of the module, which provides larger rigidity for the latch / unlocking mechanism and eliminates the possibility that the latch / unlocking mechanism comes off the housing of the module due to application of excessive forces to a spider of the latch / unlocking mechanism. Furthermore when the housing of the module is inserted in a cage and when the housing is drawn out of the cage, the slider arm is not in contact with the cage. The distal end part of the slider arm is maintained out of the housing of the module so as to allow a hook at the distal end part to be broken away from a cage latch during an unlocking period.

Description

technical field [0001] The present invention relates to pluggable optical communication modules. More particularly, the present invention relates to a pluggable optical communication module with an improved latch / unlock mechanism. Background technique [0002] One type of fiber optic cable is terminated on one or both ends with a pluggable optical communication module. The optical communication module is an optical receiver module, an optical transmitter module or an optical transceiver module. The connector module has a module housing that houses the electrical, optoelectronic and optical components of the module. While various insertable module designs exist, the module housing is typically configured to be inserted into an opening formed in the cage. Module housings of this type typically include a pair of cage latch stops formed on opposing outer side walls of the module housing that engage a pair of cage latches formed on opposing side walls of the cage to secure the...
