The new generation of WiFi6 supports 802.11ax mode, so what is the difference between 802.11ax and 802.11ac mode?

Compared with 802.11ac, 802.11ax proposes a new spatial multiplexing technology, which can quickly identify air interface conflicts and avoid them. At the same time, it can more effectively identify interference signals and reduce mutual noise through dynamic idle channel assessment and dynamic p... Read More

How to choose an optical module?

When we choose an optical module, in addition to the basic packaging, transmission distance, and transmission rate, we should also pay attention to the following factors: 1. Fiber type Fiber types can be divided into single-mode and multi-mode. The center wavelengths of single-mode optical modu... Read More

The structural composition and key technical parameters of the optical module

1. The average transmitted optical power refers to the arithmetic mean of the optical power when the signal logic is 1 and the optical power when it is 0. 2. The extinction ratio refers to the ratio of the average transmitted optical power of all “1″ codes to the average transmitted ... Read More
