At present, the mainstream distributor in the market is mainly based on two kinds of technical forms: the Fused Biconical Taper (FBT) and the PLC. In the same way, two kinds of technical forms are superior. No matter what type of technology is based on the divider, it is based on the cascade of 1 x 2 basic structures. The 1 x 2 structure of FBT is a coupler, and the PLC is a Y branch structure. This seemingly simple Y branch component is not really simple, because the performance of the divider is largely determined by it. It is inconvenient to discuss how to design a Y branch with excellent performance, which belongs to Classified technology. This is a brief introduction to the working principle of a Y branch structure based on planar optical waveguide, that is, the 1 x 2 divider. In fact, it is from the physical nature of the rough explanation why the 1 x 2 divider, whether it is the upstream or downlink signal, its insertion loss is 3 dB.
