Splitting an incident light beam into two or more light beams or vice versa, Fiber optic splitter or referred to as beam splitter is a passive optical component. Multiple input and output ends are present in a fiber splitter. For the convenience of network interconnections in a network, a fiber optic splitter is implemented whenever there is a requirement of the division of light transmission.
Working of Fiber Optic Splitter
Whenever there is the transmission of the light signal in a single-mode fiber, the light energy is not able to concentrate in the fiber core. Through the cladding of fiber, a small amount of energy is spread. The light-transmitting in a fiber adapter can enter into another optical fiber now if two fibers are enough for each other. Therefore, in the optical signal, the reallocation technique can be achieved in multiple fibers.
Classification of Fiber Optic Splitter: There are two types of fiber optic splitter, one is a PLC splitter another is an FBT splitter.
PLC is referred to as a planar lightwave circuit. There is a light circuit present at the edge of the chip that to in a ribbon form mounted on a carrier and fibers. As the material of lightwave circuit PLC splitter typically adopts silica glass and it also accepts various types of polished finishes. In a PLC splitter the substrate, waveguide, and lid are three basic layers.
To fuse several fibers FBT or fused biconical taper make use of the traditional technology. For a specific location and length, the alignment of fibers is done by heating. Until the parameters of the fiber collimator reach the required standards there will be no stopping for the fusion process. Fused fibers are very fragile; as a result, they are protected by a glass tube that is made of epoxy and silica powder. For the convenience of network interconnections, a fiber optic splitter is used.
PLC splitter provides better performance and fewer limitations, but if you have budget limitations then FBT splitter is less expensive. You can even take the help of a professional if you are still not sure which one to choose.
