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.In combination with these conditions, 800g qsfp-dd It can still let us see good development and bring fresh vitality to the whole market. https://www.3coptics.com/
