Fiber optic splitter is used to split the fiber optic light into several parts at a certain ratio. For example, a 1X2 50:50 fiber optic splitter will split a fiber optic light beam into two parts, each get 50 percent of the original beam. Here the ratio is called splitting ratio. Fiber optic splitters can be terminated with different kinds of connectors, the main package could be box type or stainless tube type, one is usually used with 2mm or 3mm outer diameter cable, the other is usually used with 0.9mm outer diameter cables.
Fiber optic splitters are important passive components used in fiber optic communications. Nowadays two kinds of fiber splitters are popular used, one is the traditional fused type fiber optic splitter, which features competitive prices, the other is PLC fiber optic splitter ,which is compact size and suit for density applications. Both of these two types fiber splitters has its advantages to suit for different requirement.
