1m (3.28ft) HPE M-series R4G19A Compatible SFP28 to SFP28 DAC 25GBASE-CR 25Gbps Passive Direct Attach Twinax Copper Cable

1m (3.28ft) HPE M-series R4G19A Compatible SFP28 to SFP28 DAC 25GBASE-CR 25Gbps Passive Direct Attach Twinax Copper Cable HPE M-series R4G19A compatible DAC is a passive 25Gbps SFP28 to SFP28 direct attach cable for use in 25GBASE Ethernet network. SFP28 DAC provides 25.78Gb/s throughput for 1m interconnection with high speed twin-axial copper cable. This DAC is fully compliant with SFP28 Multi-Source Agreement (MSA), IEEE 802.3by 25GBASE-CR and 25GAUI standard. Its twin-axial copper cable’s wire gauge is 30AWG and pre-terminated with MSA compliant 20-pin edge type connectors. Standard length options cover from 1 meter 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 M-series R4G19A direct attach cables.
