With the mass construction of data centers and 5G networks, the demand for high-speed optical modules will increase rapidly. At present, the high-speed optical modules entering mass production mainly include:
(1). 400G rate：QSFP/QSFP-DD
(2). 200G rate：QSFP/QSFP-DD
(3). 100G rate：QSFP28/CFP4/CFP2/CFP/CXP
(4). 25G rate：SFP28
(5). 10G rate：SFP+/XFP
Challenges for optical module testing
(1). Test items, test equipment complex.
(2). Testing takes a huge amount of time and human resources.
(3). The cost of test equipment and the development cost of the whole test system is high.
