0.5m (1.64ft) Dell Networking 331-8148 Compatible QSFP to 4 SFP DAC 10GBASE-CR 4x 10Gbps Passive Direct Attach Twinax Breakout Copper Cable Dell Networking 331-8148 compatible DAC is a passive 4x 10Gbps QSFP to 4 SFP direct attach breakout cable for use in 10GBASE Ethernet network. QSFP breakout DAC provides 4x 10.31Gb/s throughput for 0.5m interconnection with high speed twin-axial copper cable. This DAC is fully compliant with QSFP /SFP Multi-Source Agreement (MSA), IEEE 802.3ae 10GBASE-CR and SFI standard. Its twin-axial copper cable’s wire gauge is 30AWG and pre-terminated with MSA compliant 38/20-pin edge type connectors. The breakout DAC cable splits 4 branches of 10Gbps NRZ signals from QSFP into SFP . Standard length options cover from 0.5 meters to 7 meters. MSA memory map is accessible via 2-wire (TWI/I2C) interface. Our breakout DACs are factory pre-programmed for compatibility, perform alternatively to genuine Dell Networking 331-8148 direct attach cables.
