1m (3.28ft) Generic Compatible QSFPDD-400G-DAC30-1M 400G QSFP-DD PAM4 Passive Direct Attach Twinax Copper Cable


direcXource's QSFPDD-400G-DAC30-1M DAC is a passive 400Gbps QSFP-DD to QSFP-DD direct attach cable for use in 400GBASE Ethernet. QSFP-DD DAC provides 400Gb/s throughput for 1m interconnection with high speed twin-axial copper cable. Standard length options cover from 0.5 meters to 3 meters. The QSFP-DD DAC cable implements 8 independent 50 Gbps PAM4 transmit and receive signal channels in each differential pair for an aggregate 400 Gbps data rate. It also supports 8 channels 25 Gbps NRZ signals for 200 Gbps interconnection. This DAC is fully compliant with QSFP-DD Multi-Source Agreement (MSA), IEEE 802.3cd 400GBASE-CR8 and 400GAUI-8 standard. The twin-axial copper cable's wire gauge is 30AWG and pre-terminated with MSA compliant 76-pin edge type connectors. MSA memory map are accessible via 2-wire Interface (TWI/I2C). Our DACs are factory pre-programmed for compatibility, perform identically to generic MSA direct attach cables.
