400G QSFP-DD to 2x200G QSFP56 passive branch cable is a high-speed fiber optic cable solution for data communications and network connectivity. It is mainly used to connect two devices, one of which supports 400G QSFP-DD interface and the other supports two 200G QSFP56 interfaces.
The cable adopts QSFP-DD (Quad Small Form-factor Pluggable Double Density) and QSFP56 interface standards, which is a small high-density optical module interface used to transmit high-speed data. 400G QSFP-DD and 200G QSFP56 are two different optical module types, supporting data transmission rates of 400Gbps and 200Gbps respectively.
The design of 400G QSFP-DD to 2x200G QSFP56 passive branch cable makes it possible to branch out two 200G QSFP56 interfaces from one 400G QSFP-DD interface. This design enables high-speed connections between devices while reducing the number of physical connections required and the space required. The optical fibers and connectors in passive drop cables are configured to distribute and pass data streams without the need for additional electronics or signal processing.
400G QSFP-DD to 2x200G QSFP56 passive branch cable can provide high-speed, reliable data transmission and is suitable for network environments that require large bandwidth and high performance, such as data centers, cloud computing, and supercomputers. It provides data center architecture with greater flexibility and scalability while reducing complexity and cost.
