3m (9.84ft) Generic Q4S-50G-DAC28-3M Compatible PAM4 QSFP56 to 4 SFP56 DAC 50GBASE-CR 4x 50Gbps Passive Direct Attach Twinax Breakout Copper Cable Dawnray’s Q4S-50G-DAC28-3M DAC is a passive 4x 50Gbps QSFP56 to 4 SFP56 direct attach breakout cable for use in 50GBASE Ethernet network. QSFP56 breakout DAC provides 4x 51.56Gb/s throughput for 3m interconnection with high speed twin-axial copper cable. This DAC is fully compliant with QSFP56/SFP56 Multi-Source Agreement (MSA), IEEE 802.3cd 50GBASE-CR and 50GAUI-1 standard. Its twin-axial copper cable’s wire gauge is 28AWG and pre-terminated with MSA compliant 38/20-pin edge type connectors. The breakout DAC cable splits 4 branches of 50Gbps PAM4 signals from QSFP56 into SFP56. It also supports 4x 25Gbps NRZ fanout application. Standard length options cover from 0.5 meters to 3 meters. MSA memory map is accessible via 2-wire (TWI/I2C) interface. Our breakout DACs are factory pre-programmed for compatibility, perform alternatively to generic/MSA direct attach cables.
