A plug-in insert optical splitter is a device for an optical fiber network system that can input optical signals evenly into multiple exits from a single or double inlet, or reverse work to transfer multiple optical signals into a single or double optical fiber. Here is a detailed introduction of the plug-in insert optical splitter:

1. Composition and structure: The plug-in insert optical splitter is mainly composed of insert and adapter, which is composed of three parts of optical cable, optical fiber array and optical cable. The plug-in insert optical splitter is made of semiconductor process (lithography, corrosion, development, etc.). The optical waveguide array is located on the upper surface of the chip, and the splitter function is integrated on the chip, that is, 1 and 1 division are realized on one chip. Then, the multi-channel fiber array is coupled to the input and the output of the chip.

2. Working principle: The working principle of the plug-in insert optical splitter is when the input optical signal is converted into the electrical signal (DC voltage), and then output to the display instrument; and the signal of the electrical signal into optic is completed by the optical part. The optic source is mainly composed of optic emitting diode and laser diode; the reflection plate is mainly used to refract the incoming parallel beam or reflect the desired beam to the measured object. The splitter is the key component of the whole system. Its main function is to divide the optic waves from different frequencies of the emitter into different wavelength components and send them into the corresponding detection unit for detection. The function of the fiber connector is to connect a single fiber of the input terminal with multiple fibers of the output port to form a complete communication link.

3. Features and advantages: The plug-in insert optical splitter has the characteristics of small size, wide working wavelength range, high reliability, good spectral uniformity, etc. It is especially suitable for passive optical network (EPON, BPON, GPON, etc.) to connect the local terminal and terminal equipment and realize the splitter of optical signal.
