In today's optical network topology, the appearance of fiber optic splitters is of great significance to help users maximize the performance of optical network circuits. A fiber optic splitter, or sometimes called a beam splitter, is a passive optical element that can split an incoming light beam into two or more beams and vice versa. The device contains multiple inputs and outputs. Whenever the optical transmission in the network needs to be split, a fiber splitter can be used to facilitate network interconnection.

The fiber optic splitter is a device that divides the fiber optic lamp into several parts according to a certain proportion. For example, when a bundle of fibers exits a 1X4 split splitter, it will be split equally into 4 fibers, i.e. each bundle is 1/4 or 25% of the original light source. Fiber splitters are different from WDM. WDM can split fiber light of different wavelengths into different channels. Fiber splitters distribute optical power to different channels. From a technical point of view, there are two commonly used optical splitter types: FBT (Fused Biconical Taper) and PLC (Planar Lightwave Circuit).


PLC Splitter vs FBT Splitter

Splitter technology has advanced over the past few years with the introduction of PLC splitters. Compared to traditional FBT splitters, it has proven to be a more reliable device. Again, they are similar in size and appearance, and both types of splitters provide data and video access for business and private customers. However, the technology behind these splitters varies internally, so service providers can choose a more suitable solution.

Splitting ratio

FBT splitters use two (or more) fibers. Remove the coating from the fibers. Both fibers are drawn simultaneously under the heating zone, thereby forming a double cone. This special waveguide structure allows the splitting ratio to be controlled by controlling the twist angle of the fiber and the length of the stretch.


PLC optical splitter is a micro-optical element that uses photolithography technology to form optical waveguides on a medium or semiconductor substrate to achieve branch distribution functions. Various packaging types including bare fiber type, mini steel tube typeABS box typecassette insertion type, tray type, and rack-mounted type can be chosen.

How to choose the right optical splitters

Considering the difference in the number of users and the transmission distance, the optical power distribution in the line requires the use of fiber splitters. Since PLC splitters can't handle different optical ratios, it's time to use FBT splitters.


However, PLC distributors have advantages in some other important aspects compared to FBT distributors. It is not sensitive to different wavelengths, so the PLC splitter can work at different wavelengths without causing too much loss. A single component can be split into multiple channels, up to 64 or more. The PLC splitter is lower cost for multi-channel. The more channels, the lower the cost.
