Optical splitters play an important role in FTTH PON networks where a single optical input is split into multiple output, thus allowing a single PON interface to be shared among many subscribers. The optical splitters have no active electronics and don't require any power to operate. 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. The differences between the two have been stated in another article FBT Splitters vs. PLC Splitters: What Are the Differences? So it is unnecessary to go into the details here. Besides these, what other information do you know about optical splitters? Keep reading this article, you may get more about it.
