This professional analysis compares FBT and PLC splitters across performance metrics—such as insertion loss, uniformity, wavelength stability, and power handling—and cost implications for common PON splitting configurations, including low-ratio (1x2, 1x4), medium-ratio. This professional analysis compares FBT and PLC splitters across performance metrics—such as insertion loss, uniformity, wavelength stability, and power handling—and cost implications for common PON splitting configurations, including low-ratio (1x2, 1x4), medium-ratio. In this guide, you'll learn how fiber splitters function in PON networks, the difference between PLC and FBT types, and how to choose the best model for your rollout in 2025. What Are Fiber Optic Splitters in PON? Fiber splitters are passive devices that divide one optical input signal into. PLC splitter, also called Planar Waveguide Circuit splitter, is a device used to divide one or two light beams into multiple light beams uniformly or combine multiple light beams to one or two light beams. It is a passive optical device with many input and output terminals, especially applicable to. In passive optical networks (PONs), optical splitters are essential for distributing signals from a central optical line terminal (OLT) to multiple optical network units (ONUs), enabling efficient fiber-to-the-home (FTTH), fiber-to-the-building (FTTB), and enterprise broadband deployments. It is one of the core components in Passive Optical Networks (PON) and is widely used in FTTx deployments, where a single fiber connection.
