In this way, the optical fiber communication bandwidth can be released and the advantage of large communication capacity and high communication rate can be achieved. Therefore, the optical switching technology has attracted a lot of attention and is considered the most important part of the next-generation broadband technology. 1. Optical Switching Optical Signal multiplexing generally involves three methods: Air division multiplexing

In data communication, multiplexing technology greatly improves the channel transmission efficiency and has been widely used. Multiplexing technology is to combine multiple signals at the sending end (such as the mixer used at the front-end of broadcasting and television), and then implement transmission on a dedicated physical channel. The receiving end then separates the compound signal. Multiplexing technology is mainly divided into two categories: Frequency Division Multiplexing (Frequency D

the inverted F antenna, multi-frequency resonance is achieved by means of Slotting and adding support segments. However, to implement multi-frequency operations, the introduced structure is often complicated. Based on this, we have designed a micro-band antenna that can work in WLAN (2.4 GHz and 5.8 GHz) and WiMAX (3.5 GHz) at the same time. The antenna uses three L-shaped micro-strips with a 1/4-Wavelength Single Pole combination to implement three-

. electrons rotate around the nucleus in a certain orbit. This is like the earth we live in and the planet Venus, Mars, and other planets all rotate around the Sun. Every electron has a certain amount of energy in a certain orbit, or each orbit has a definite energy level. The orbital level close to the nucleus is low, and the orbital level farther away from the nucleus is higher. The energy level difference between tracks is called the energy level difference. When electrons transition from low
