400G QSFP-DD to QSFP-DD Active Optical Cable
400G QSFP-DD AOC (Active Optical Cable) assemblies are designed to support 400G Ethernet. 400G QSFP-DD AOC components are compatible with IEEE 802.3cd 400GBASE-SR8 and IEEE 802.3cd 200GBASE-SR4. The module supports eight electrical interface lanes that operate in 50G PAM4 encoding mode, enabling 400G (8x50G) data rates. The 400GBASE-SR8 QSFP-DD AOC assembly is used to connect multiple 400G signals from the server side (NIC) to the data center aggregation switch.
Warranty : 30-Day Free Return, 3-Year Free Replacement, 5-Year Warranty, Lifetime After-sales Technical Support.
