It is an optical fiber tandem device with many input and output terminals, especially applicable to a passive optical network (EPON, GPON, BPON, FTTX, FTTH etc. A splitter is not a filter like a wavelength division multiplexer (WDM). Rarely, there can be two inputs to provide potential redundancy of route. Light power goes in and light power coming out of the various legs is reduced in. In the backbone of modern Fiber-to-the-Home (FTTH) networks, optical splitters serve as the unsung heroes that enable cost-efficient connectivity for millions of subscribers. By dividing a single optical signal from a central Optical Line Terminal (OLT) into multiple outputs for Optical Network. A PLC (Planar Lightwave Circuit) splitter is a passive optical device that evenly distributes optical signals into multiple output ports using silica waveguide technology. This guide will demystify this pivotal passive device, exploring its types, working principles.
