EPON is a passive optical network based on Ethernet, which is an important part of optical access technology. The PON network consists of OLT (optical line terminal), ODN (passive optical splitter network) and ONU (optical network terminal). Partial composition. OLT equipment is located at the core position in the network topology. It accesses multiple service networks upwards, and accesses multip...

With the increasing demand of network throughput and bandwidth, the demand of 40G high-speed optical module also increases. At present, the common 40G optical modules on the market include 40G QSFP+ SR4, 40G QSFP+ LR4 and 40G QSFP+ ER4. Since the transmission distance of the above optical modules cannot fully cover the transmission distance requirements of the data center, the 40GBASE-SR4 optical ...
