They are typically installed in each optical network between the PON OLT (optical line terminal) and ONTs (optical network terminals) that the OLT serves. Generally, two kinds of fiber optic splitters are popular, which are FBT splitters and PLC splitters. Unlike active devices (which require power), splitters operate without electricity, relying solely on the physics of. An optical splitter enables a single optical signal to be distributed to multiple end users, making large-scale FTTH and GPON deployments economically viable. As XGS-PON continues to be adopted, some service providers keep the 1x32 split and some have chosen 1x64 splits. As FTTH networks continue to.
