What Is a 1×4 PLC Splitter?

A 1×4 PLC splitter is a passive optical device that takes one input fiber signal and evenly distributes it to four output fibers. This device plays a crucial role in Passive Optical Networks (PONs), enabling service providers to connect a single optical line terminal (OLT) to multiple end-users or optical network terminals (ONTs).

Using advanced photolithographic waveguide technology, the 1×4 splitter provides superior optical performance over a wide range of wavelengths, typically from 1260 nm to 1650 nm, making it compatible with most modern optical transmission systems.
