In a PON network, a device called an optical line terminal (OLT) is placed at the head end of the network. A single fiber-optic cable runs from the OLT to a nonpowered (passive) optical beam splitter, which multiplies the signal and relays it to many optical network terminals. According to the Broadband Forum, PLC splitters are essential for achieving scalable and cost-effective GPON and XGS-PON deployment in access networks. 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. This guide focuses on two critical aspects of optical splitters that define FTTH performance: split ratios (how signals are divided) and splitting architectures (how splitters are deployed). By understanding these elements, network operators can design PON (Passive Optical Network) systems that. In a PON network, the splitter which is located between OLT and ONU functions as a traffic hub, adeptly managing the flow of optical signals. It operates like a sophisticated intersection, directing the singular flow of optical fibers to various users or devices, ensuring the efficient circulation. PON, developed in the mid-1990s, was originally designed to allow internet service providers (ISPs) to deliver broadband triple-play services (data, voice, and video) to residential users. Its purpose was to reduce the number of fiber runs needed to reach multiple end-user locations and to. A splitter is not a filter like a wavelength division multiplexer (WDM). Typically, but not always, there is one input in and multiple outputs.
