400G QSFP-DD Direct Attach Cable

Generic Compatible 400G to 400G DAC Cable (1-3m, Passive, QSFP-DD to QSFP-DD, 26 – 30AWG)

Cable assemblies consisting of 400G QSFP-DD DAC cable are effective replacements for fiber optics. Each of the 16 pairs on the single QSFP-DD end may transmit data at up to 50Gb/s, and the cable connects each pair to the other QSFP-DD end. Each QSFP-DD port can be addressed by an EEPROM, which provides product information that the I2C interface can read or write. DAC cable assemblies are high-performance, low-cost I/O solutions for LAN, HPC, and SAN that conform with IEEE802.3cd and QSFP-DD-MSA. The high-speed cable assemblies meet the 400Gigabit Ethernet connection of rack-to-rack and adjacent rack.
