5m (16.40ft) HPE BladeSystem 845408-B21 Compatible QSFP28 to QSFP28 DAC 100GBASE-CR4 100Gbps Passive Direct Attach Twinax Copper Cable

HPE BladeSystem 845408-B21 compatible DAC is a passive 100Gbps QSFP28 to QSFP28 direct attach cable for use in 100GBASE Ethernet network. QSFP28 DAC provides 103.1Gb/s throughput for 5m interconnection with high speed twin-axial copper cable. This DAC is fully compliant with QSFP28 Multi-Source Agreement (MSA), IEEE 802.3bj 100GBASE-CR4 and CAUI-4 standard. Its twin-axial copper cable’s wire gauge is 26AWG and pre-terminated with MSA compliant 38-pin edge type connectors. The DAC cable implements 4 independent 25.78125Gbps NRZ transmit and receive signal channels in each differential pair for an aggregate 103.125Gbps data rate. Standard length options cover from 0.5 meters to 5 meters. MSA memory map is accessible via 2-wire (TWI/I2C) interface. Our DACs are factory pre-programmed for compatibility, perform alternatively to genuine HPE BladeSystem 845408-B21 direct attach cables.
