Class topic
Post 1. How to choose the single-mode fiber？
There are different types of single-mode fiber. It depends on the length of the link, the wavelength of transmitters, data rate, and CWDM or DWDM. Singlemode fibers are mainly used for outdoor installation, from a few meters to a few hundred kilometers. So, how should we choose it?... More
Post 2. What is IPv6
An IP address is a unified address format provided by the IP protocol. It allocates a logical address to each network and each host on the Internet to shield the differences between physical addresses. So, what is IPv6?... More
Post 3. What is Wi-Fi7
The Wi-Fi 7 standard, called 802.11be, features faster speeds than Wi-Fi 6 and very sensitive signal detection. What is most likely to become Wi-Fi 7 is the IEEE 802.11be standard in development, which is a direct relative of Wi-Fi 6, or 802.11ax. What else will Wi-Fi 7 bring us?... More
