The 400G QSFP112 Active Electrical Cable is copper cable with retimer chip at both ends for complete signal integrity and is designed for use in 400G Ethernet. AEC can solve the technical barriers of data loss in PAM4 signal transmission. Compared with traditional passive copper cables, 400Gbps AEC cable can achieve long-distance transmission of 5m without significantly increasing signal attenuation.
The active electrical cable can be used in QSFP-DD(4x 100G) switches, ConnectX-7/QSFP112 adapters or BlueField-3/QSFP112 DPUs, and it is compliant with the QSFP112 MSA (Multi-Source Agreement), IEEE 802.3ck 400GBase-CR4, and CMIS 5.0 standards. With the advantages of easy installation, high-speed performance and cost-effectiveness, the cable is suitable for short-distance connectivity within a rack or between adjacent racks in data centers.
