How to understand 5G’s fronthaul, midhaul and backhaul

　　With the rapid development of information technology and the increasing demand for data transmission, optical communication technology plays a vital role in modern networks. DWDM technology greatly increases the data transmission capacity by using multiple optical signals of different wavelengths to transmit simultaneously on one optical fiber. The tunable optical module can switch between multiple wavelengths to achieve flexible and efficient wavelength management. The 25G Tunable DWDM tunable optical module combines these two technologies to provide higher data rates and greater adaptability.To get brand praise, 400g qsfp-dd It is necessary to have the spirit of constantly improving the quality of products, but also to have a bunch of eternal heart fire. https://www.3coptics.com/
