The difference between 200G and 400G optical modules mainly lies in the different transmission rates, as follows:
1, the transmission rate is different: 400G optical module transmission rate is 2 times the 200G optical module, that is, the maximum transmission rate of 400G optical module is 2 times the maximum transmission rate of 200G optical module.
2, different encapsulation type: 200G optical module mainly has QSFP-DD and QSFP56 two types of encapsulation. 400G optical module is currently the mainstream encapsulation type is QSFP-DD.
3, the cost is different: 400G optical module cost is higher than the cost of 200G optical module, because 400G optical module requires more optical components and more complex manufacturing process.VANDESAIL - Accelerating the world with technology.
