400G QSFP-DD to 4xQSFP56 DAC Cable

Teosco 400G QSFP-DD to 4xQSFP56 Copper Direct Attach Cables (DAC) are designed for use in 400Gigabit Ethernet and EDR/HDR InfiniBand systems, which provide connectivity between systems units with a 400GbE connector on one side and four separate 100GbE connectors on the other four sides. The cables are compliant with IEEE 802.3cd, SFF-8665, QSFP-DD MSA standards and InfiniBand EDR/HDR standards. It is a high performance, cost efficient I/O solution for LAN, HPC and SAN with eight-channels of up to 50Gbps (PAM4) per channel and aggregation rates of up to 400Gbps. Each QSFP-DD/QSFP56 port can be addressed by EEPROM to provide product information, which can be read or write by I2C interface. The cables are suitable for cost-effective close-range interconnections within the equipment rooms of Telecom Operators, Data Centers and Cloud Computing Environments, etc.
