Splitter loss refers to the optical power lost when a signal is divided into multiple channels. This loss is primarily quantified as insertion loss, which measures the reduction in signal power due to the splitter's presence in the optical path. These are known as passive optical splitters, and they perform the function. Optical splitters play a crucial role in Fiber to the Home (FTTH) Passive Optical Network (PON) systems, efficiently distributing a single optical signal to multiple destinations. Use 2×N when two inputs feed the same distribution stage. Common values: 2, 4, 8, 16, 32, 64. 5 dB depending on splitter type. Understanding the types of splitters, their impact on network performance, and how to measure their losses ensures high-quality network operation and facilitates optimal splitter selection based on.
