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...

SFP, SFP+, SFP28, QSFP+ and QSFP28 are the packaging types of optical modules. These hot-swappable optical modules can be used to connect network switches and other network devices (such as servers, etc.) for data transmission. Before clarifying the difference between these package types, you need to understand what the SFP, SFP+, SFP28, QSFP and QSFP28 packages are. Next ETU-LINK w...
