1. Introduction to fiber optic PLC splitter

A. Basic concepts of fiber optic PLC splitter

The optical fiber PLC optical splitter is an important device used in optical fiber communication systems. It is used to distribute optical signals to multiple output ports or combine multiple input signals into one output port. The basic concept is to use optical waveguides on optical waveguide planar chips to achieve distribution and merging of optical signals by etching different waveguide structures on the chip surface.

The principle of PLC optical splitter is based on optical phenomena such as total internal reflection of light and multi-mode interference. When the optical signal enters the PLC chip from the entrance, it will be distributed or combined among different waveguides according to the design and structure on the chip, and finally achieve the expected optical power distribution ratio.

B. Structure and principle of fiber optic PLC splitter

1. Structure:

   • Fiber PLC optical splitter usually consists of three main parts: input port, optical waveguide planar chip and output port.
   • The input port is the entrance to introduce optical signals into the PLC chip.
   • The optical waveguide planar chip is the core component of the PLC optical splitter, which contains structures such as optical waveguides and couplers, and is used to distribute or combine optical signals.
   • The output port is the port that outputs optical signals from the PLC chip. There can be one or more.

2. How it works:

   • The optical signal enters the PLC chip through the input port.
   • On the chip, optical signals are distributed or combined through different optical waveguide structures depending on the chip’s design.
   • The distribution and merging process is achieved through optical phenomena such as total internal reflection of light and interference.
   • Finally, the optical signals are distributed or combined into the expected output ports to complete the splitting or combining function of the optical signals. The advantages of PLC optical splitters include compact structure, low loss, high reliability, and wide application in multi-wavelength and high-speed communication systems.
