In this article, we will delve into four critical indicators: insertion loss, splitting ratio, isolation and stability. Help you make informed decisions when selecting fiber optic splitters for your network infrastructure. It enables one signal source (OLT) to serve multiple endpoints (ONTs or. Fiber splitters are a critical component of any FTTH access network. Although often viewed as a simple passive device, the choice of splitter type, split ratio, and connector interface has a direct impact on network performance, scalability, installation efficiency, and long-term operational cost. Each mirror reflects the same light. That's how the splitter works, except it does it with precision, and at the speed of light.
