40% SMALLER THAN LC
Compared to the legacy LC connector, SENKO’s CS has a narrower and shorter design, making it ideal for applications such as cassettes, modules, patch panels, and switches where higher density is required. Additionally, the CS’s compact and sturdy design makes it a suitable choice for high-density cable assemblies that need to fit into tight spaces, and for easy insertion through ducts and conduits.
