Optical Splitters Introduction:The Fiber Optic Splitter, also named beam splitter, is with multiple input and multiple output end fiber tandem devices, M * N is commonly used to represent a divider with M input and N output.,with coaxial cable transmission system, network system also needs to be light signal is coupled, branch, distribution, and the optical divider is needed for implementation.
Two Kinds Of Fiber Splitters:
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(planar lightwave circuit) 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.
Fused Biconic Tapered(FBT) fiber optic splitters are mature technology types, it is low cost and easy to make, but fused fiber optic splitters optical loss are sensitive to wavelength and this is big disadvantages. PLC fiber optic splitters are small size and wide working wavelength, they are more reliable, suitable to use in passive optical network fiber optic splitting, we supply the PLC Splitters including 1*N PLC splitter module and 2*N PLC splitter module .The common configurations are 1×4, 1×8, 1×16, 1×32 and 1×64 PLC Splitters;but 2×4, 2×8, 2×16, 2×32 configurations are also available.
The Theory For Optical Fiber Splitters:
Fiber optic splitter is a device that split the fiber optic light into several parts by a certain ratio.Fiber optic splitters enable a signal on an optical fiber to be distributed among two or more fibers. Since splitters contain no electronics nor require power, they are an integral component and widely used in most fiber optic networks. For example, a 1X4 LC type equal splitting ratio fiber optic splitter can split the fiber optic light signal into four equal 25% parts and sent to the 4 different channels, LC is the connector type on the splitters. Fiber optic splitter key parameters include the optical loss, splitting ratio, isolation, PDL, etc.The diagram below shows how light in a single input fiber can split between four individual fibers (1×4):
