With the rapid development of optical communication and Internet in recent years, users demand for the network is also homeopathic surge, which led to the telecommunications backbone of the annual flow is 50% to 80% of the rapid growth. In order to adapt to the development trend of 10G-40G-100G or 10G-25G-100G in the network market, 100G optical module came into being and developed rapidly in the market, which played a vital role in constructing 100G network system. Since the advent of the 100G network, IEEE, multi-source protocol (MSA) industry alliance and other institutions are for 100G optical module developed a number of standards. as the picture shows: Depending on the package, the 100G optical module can be divided into CFP / CFP2 / CFP4 optical modules, CXP optical modules and QSFP28 optical modules. The specific parameters are shown in the table below: The QSFP28 optical module and QSFP optical module design concept is the same, there are four transmit and recei...
