3. a kind of pluggable optical module shell mechanism as claimed in claim 2, which is characterized in that the upper casing is additionally provided with
Positioning surface, the upper positioning surface and the lower positioning surface cooperate card volt circuit plate, and the circuit board is made to be fixed on the optical module
In cavity.
4. a kind of pluggable optical module shell mechanism as claimed in claim 3, which is characterized in that the pull ring is additionally provided with hand
Portion, sleeve and cantilever are held,
Hand-held part provides pulling force under external force and rotates the pull ring；
Sleeve is the circle ring column that plastic material is made into, is fixed on the hand-held part, and is made by different colours,
For identifying the different operation wavelength of the optical module；
Cantilever forms closed framework with the hand-held part, rotation axis, and the rotation for the pull ring provides torque.
5. a kind of pluggable optical module shell mechanism as claimed in claim 4, which is characterized in that the optical module further include:
Optical transceiver, circuit board and dust plug,
Optical transceiver is fixed in the optical module cavity in the pressure of the assembly card of the mounting groove and the boss, is used for light
The reception and transmitting of signal；
Circuit board is provided with locating slot, in the cooperation of the locating slot and the positioning column, the lower positioning surface with it is described fixed
Under the cooperation of plane, the circuit board is fastened in the cavity of the optical module；
Dust plug is plugged at the external tapping of the optical module, protects the optical module in the optical module off working state
External tapping.
