400G QSFP-DD DAC
The 400G QSFP-DD DAC is a connectivity solution for high-speed data transfer that utilizes the QSFP-DD (Quad Small Form-factor Pluggable Double Density) interface specification to support data rates of 400Gbps per port.
QSFP-DD is an evolved version of the QSFP interface that achieves double the data rate by increasing the number of pins on the same size socket. As a result, each QSFP-DD port can support higher data throughput.400G QSFP-DD DAC is a type of Direct Attach Cable (DAC, Direct Attach Cable) under the QSFP-DD interface specification and is used for high-speed data transmission over short distances.
This type of DAC uses copper conductors to transmit data signals and is typically suitable for in-rack connections or connections between adjacent devices.400G QSFP-DD DACs have QSFP-DD plugs on both ends and can be connected directly to the ports of devices that support the QSFP-DD interface without the need for additional optical modules or fiber.
