Each OLT port has a fixed bandwidth (e. A higher split ratio means this bandwidth is shared among more subscribers: A 1Gbps OLT port with a 1:32 splitter gives each subscriber ~31Mbps (theoretical)—enough for streaming 4K video, gaming, and home office use. Bandwidth is shared amongst customers in a PON, and the bandwidth received by a customer is not related to the power received at the optical network terminal (ONT) as long as the power is high enough so the ONT can operate. Splits are most commonly factors of 2, such as 1x2, 1x4, 1x8, 1x16, 1x32. By understanding these elements, network operators can design PON (Passive Optical Network) systems that balance bandwidth, cost, and reliability. Introduction: The Role of Optical Splitter in PON Network Before delving into split ratios and architectures, it's essential to ground their. An optical splitter is a small, passive device—no power needed! —that splits one incoming light signal into multiple identical outputs. You'll often see ratios like 1:8, 1:16, 1:32, or even 1:64, which tell you how many ways the signal is divided. It allows service providers to save money. In this article, we explain the definition, working principles, types, and selection tips for optical splitters.
