Asymmetrical PLC Splitter Data Sheet

Aug 27, 2025 - Asymmetrical PLC Splitter Data Sheet Product Overview Asymmetric PLC (Planar Lightwave Circuit) Splitters are passive optical components designed to distribute optical signals unevenly across multiple outputs, offering flexible power allocation for complex network topologies. Unlike standard symmetrical splitters, asymmetric PLCs are engineered to retain higher power on the express path while tapping minimal signal for local access. This makes them ideal for multi-tier FTTH deployments, long-reach backbone transmissions, rural broadband expansion, and cascaded star-topology networks. FS Asymmetric PLC Splitters offer stable optical performance and are available in a wide range of split ratios—such as 95/5, 75/25, 70/30, and more. With support for various connectors and form factors, FS enables tailored customization to meet specific deployment requirements, delivering precise power control and design flexibility for advanced optical networks.
