According to the different arrangement of fiber optic splitter ports, it can be divided into symmetrical star splitter and asymmetrical tree splitter; according to the type of fiber, it can be divided into single-mode fiber splitter and multi-mode fiber splitter; According. According to the different arrangement of fiber optic splitter ports, it can be divided into symmetrical star splitter and asymmetrical tree splitter; according to the type of fiber, it can be divided into single-mode fiber splitter and multi-mode fiber splitter; According. A fiber-optic splitter, also known as a beam splitter, is based on a quartz substrate of an integrated waveguide optical power distribution device, similar to a coaxial cable transmission system. The optical network system uses an optical signal coupled to the branch distribution. Optical splitters are a very important component in fiber optic links, widely used in. According to the method of production of optical splitters, they are divided into two groups: FBT (Fused Biconical Taper) splitters. They are easy to produce and cheap.
