What equipment is needed for optical module testing?

Now more and more customers want to know the technical information of optical modules. Today we will briefly summarize the equipment required for optical module testing! After an optical module is made into a finished product, in order to ensure the quality of the product, it has to go through multiple steps of testing before it can be shipped.

 

1. First measure the transmitted optical power, receiving sensitivity, eye diagram, extinction ratio and error code. The equipment that needs to be used are optical attenuator, optical power meter, bit error meter (adjust optical power and sensitivity by rate) and eye diagram instrument.
2. Then carry out high and low temperature aging test to check product stability

 

3. Test on the switch to check product compatibility and ensure compatibility
4. Finally, the end face inspection is performed on the fiber end face detector, and the port is cleaned with a cleaning pen to keep the port clean and ensure the quality
Our tests are to strictly follow industry standards and strive to provide customers with high-quality products. Customer satisfaction is our pursuit.

 

DAC &AOC cable connection solution

DAC connection solution:

①100G QSFP28DAC direct connection: Both ends have 100G interfaces, which are suitable for stacking and direct connection between short-distance 100G devices, and are used in the same rack;

②100G QSFP28DAC connection 4*SFP28 DAC: suitable for interconnection between 100G and 25G devices, one end is 100G interface, the other end is 4 25G interfaces, supporting distance range of 1m-5m;

③40G QSFP+DAC direct connection: Both ends are 40G interfaces, suitable for stacking and interconnection between short-distance 40G devices, and the maximum transmission distance is 7M;

④40G QSFP+DAC connection 4*SFP+ DAC: It is suitable for the interconnection between 40G and 10G devices. One end is a 40G interface, and the other end is 4 10G interfaces, and the maximum transmission distance can reach 7M.

AOC connection solution:

①100G QSFP AOC direct connection: Both ends are 100G interfaces, using OM3 optical fiber for transmission distance of 70m, and OM4 optical fiber for transmission of 100m;

②100G QSFP28AOC connection 4*SFP28 AOC: suitable for the interconnection between 100G and 25G equipment, one end is 100G interface, and the other end is 4 25G interfaces;

③40G QSFP+AOC direct connection: Both ends are 40G interfaces, using OM3 optical fiber transmission, suitable for the interconnection of 40G equipment within 100m;

④40G QSFP+AOC connection 4*SFP+AOC: suitable for the interconnection between 40G and 10G equipment, using OM3 optical fiber transmission, one end is a 40G interface, and the other end is 4 10G interfaces.

In practical applications, DAC high-speed cables are recommended for distances of 1-5M, AOC active optical cables are recommended for 7-100M, and optical modules and optical cables are recommended for connections above 100M.
