Description
Technical Field
The application relates to the field of optical transmission, in particular to an optical module. The present application also relates to another optical module.
Background
In an optical transmission network, optical modules transmit and receive optical signals over optical fibers. The light-transmitting module is used as a light path core component in the optical module and has the function of coupling light emitted by the laser into the optical fiber or emitting light emitted by the optical fiber into the photodetector. For example, the QSFP DD 400G SR8 optical module integrates a 4-channel TX end (transmit end) and a 4-channel RX end (receive end).
In the prior art, all ferule (fiber ferrule) and light-transmitting module are fixed by two guide posts on the same height at left and right, but this assembly method has the following problems in practical production:
1. in actual production, the optical fiber ferrule and the light-transmitting module need to be continuously plugged and unplugged due to the process requirements. Therefore, the size of the guide post on the light-transmitting module and the size of the guide post hole on the optical fiber ferrule need to be balanced, if the two are matched too tightly, the production time is increased during actual plugging and unplugging, and the device is easy to damage, but if the two are too loose, the displacement between the optical fiber ferrule and the light-transmitting module is easy to occur after the clamping device is installed. Therefore, the performance of the initial measurement module is very good when the clamping device is not clamped, the performance is deteriorated at a moment after the clamping device is arranged, and particularly, the assembly mode of the clamping device is unreasonable under the common condition.
2. Since the optical module has a very high operating temperature, especially in the circuit portion below the light-transmitting module, the temperature may reach 70 degrees or more, so that the positioning method of the two guide posts is more likely to cause displacement and inclination between the optical fiber ferrule and the light-transmitting module due to the small deformation of the material caused by the high temperature, and the displacement and inclination are more serious especially when the tolerance design of the guide posts and the guide post holes is not reasonable.
3. If no clamping device (Clip) is added or no glue is added, the optical fiber ferrule is easy to fall off in the practical application, transportation and other processes.
As described above, the optical module according to the related art has a problem that the optical power is affected by the inclination of the optical fiber ferrule.
