Optical fiber coupler is a kind of optical fiber passive device used for transmitting and distributing optical signal. Optical fiber couplers generally have the following characteristics: First, the device is composed of optical fiber, which is an all-fiber device; second, the demultiplexing and combining of the optical field are mainly realized by mode coupling; third, the optical signal transmis...

A star coupler is a mechanical part that is usually used to transmit rotational torque and axial force. It consists of multiple axially nested gears and has many different applications. In this article, we will delve into the main functions of the star coupler and its application in various fields. Transmitting moments and axial forces The main function of the star coupler is to transmit torque an...

In modern communication systems, optical fiber communication has become the main transmission medium, and star couplers, as an important part of it, play a key role in optical fiber communication systems. First, star couplers are used for distribution of optical signals. In an optical fiber communication network, there are usually multiple users or nodes that need to communicate, and each user or ...
