This is a genuine Credo HiWire 400 Gigabit (8x56G) QSFP-DD PAM4 to 400 Gigabit (8x56G) QSFP-DD PAM4 Active Electrical Cable (AEC), 3.0 Meter (P/N: CAC43X321D1D-D0-HW). Credo's pioneering HiWire AECs are a high-performance interconnect solution engineered to meet the extreme demands of modern data centers, cloud infrastructure, and enterprise networks. This 3.0-meter AEC features QSFP-DD (Quad Small Form-Factor Pluggable Double Density) connectors on both ends, transmitting 400 Gigabit Ethernet over 8 lanes at 56Gbps using advanced PAM4 signaling. It provides a significant advantage over passive Direct Attach Copper (DAC) cables by extending reach and improving signal integrity, while offering a compelling cost and power efficiency alternative to Active Optical Cables (AOCs). This cable is ideal for flexible, high-bandwidth connections within a rack or between adjacent racks, ensuring reliable and robust 400GbE performance.
