First of all, all the optical modules shipped by our company have passed multiple verifications to ensure excellent quality. Our after-sales service is also very reliable. If any of the following adverse situations occur with the optical module, you can directly contact our company for after-sales service.
The common problems that occur during the testing process of optical modules are as follows:
The performance of the TOSA transmitting component is poor. For instance, abnormal phenomena in the transmitting module can be tested through an optical power meter. Both excessively high and low optical power values may affect performance.
The backlight current pin (PD+ pin) of the transmitting component TOSA is poorly soldered. In the manufacturing of this precise device, it is impossible to guarantee its 100% excellence, which may lead to false soldering during the spot soldering process. This false soldering will cause abnormal PD values and no current to be transmitted to the IC.
The signal pins (LD+ pin and LD- pin) of the transmitting component TOSA are poorly soldered. During the welding process, as mentioned above, this will result in the presence of no light power although there is a PD value.
The driver chip is poorly mounted or has poor performance. The most direct manifestation of this phenomenon is the failure of pinging packets or changes in quality during the pinging process.
The components (such as capacitors, resistors, inductors or magnetic beads) under the pins of the storage chip are missed, wrongly attached or defective.
The power resistors do not match.
