This optical module boasts an astonishing transmission rate of up to 400Gbps. Through four independent channels, each operating at a rate of 100Gbps in parallel, it enables ultra – high – speed and stable data transmission. Inside the data center, data interaction between servers and switches, as well as between switches, is extremely frequent. The 400G QSFP – DD DR4 optical module can efficiently and rapidly handle large – scale data transmission tasks, significantly enhancing the operational efficiency of the data center and ensuring the smooth operation of various business services.
