0.5m (1.64ft) Generic QSFP-40G-DAC30-0M5 Compatible QSFP+ to QSFP+ DAC 40GBASE-CR4 40Gbps Passive Direct Attach Twinax Copper Cable
Dawnray’s QSFP-40G-DAC30-0M5 DAC is a passive 40Gbps QSFP+ to QSFP+ direct attach cable for use in 40GBASE Ethernet network. QSFP+ DAC provides 41.25Gb/s throughput for 0.5m interconnection with high speed twin-axial copper cable. This DAC is fully compliant with QSFP+ Multi-Source Agreement (MSA), IEEE 802.3ba 40GBASE-CR4 and XLPPI standard. Its twin-axial copper cable’s wire gauge is 30AWG and pre-terminated with MSA compliant 38-pin edge type connectors. The DAC cable implements 4 independent 10.3125Gbps NRZ transmit and receive signal channels in each differential pair for an aggregate 41.25Gbps data rate. Standard length options cover from 0.5 meters to 7 meters. MSA memory map is accessible via 2-wire (TWI/I2C) interface. Our DACs are factory pre-programmed for compatibility, perform alternatively to generic/MSA direct attach cables.
