Enrich Your Knowledge About Fiber Optic Splitter

In today’s optical network topologies, fiber optic splitter is quite significant in helping users maximize the performance of optical network circuits. A fiber splitter is a passive optical component that splits an incident light beam into two or more light beams and vice versa and it is also called a beam splitter. The device consists of multiple input and output ends. Fiber optic splitter can be implemented for the convenience of network interconnections whenever there is a need for the division of light transmission in a network.

Working of Fiber Optic Splitter Work

The working principle of fiber optic splitter can be generally described in the following way. The light energy can not entirely concentrate in the fiber core when there is the transmission of the light signal in a single-mode fiber. Through the cladding of fiber, a small amount of energy will be spread. In simple words, if two fibers are close enough to each other then in an active optical cable the transmitting light can enter into another optical fiber. Therefore, in multiple fibers, the reallocation technique of optical signal can be achieved.

Classification of Fiber Optic Splitter

Today you will find that there are two types of fiber optic splitters. They are PLC splitter (planar lightwave circuit) and FBT splitter (fused biconical taper).

With the use of an optic splitter chip PLC splitter divides the incoming signal into multiple outputs. One optic splitter chip can achieve at most 64 ends. For larger applications PLC splitter is usually used. To the wavelength, the losses of PLC splitter are not at all sensitive, which then for multiple wavelengths transmission satisfies the need. The size of a PLC splitter’s configuration is small and is compact, thus the installation space can be greatly saved.

With a heat source that is similar to a one-to-one fusion splice, the fusion of an FBT splitter is done. Under a heating zone, fiber patch cable is stretched to form a double cone. Due to the commonly used materials, the cost of an FBT splitter is lower, and the splitting ratio is adjustable. But to wavelengths the losses are sensitive. According to wavelengths the devices should be selected.
