1m (3.28ft) Cisco SFP-H25G-CU1M Compatible 25G SFP28 Passive Direct Attach Twinax Copper Cable
Cisco SFP-H25G-CU1M compatible DAC is a passive 25Gbps SFP28 to SFP28 direct attach cable for use in 25GBASE Ethernet. SFP28 DAC provides 25Gb/s throughput for 1m interconnection with high speed twin-axial copper cable. Standard length options cover from 1 meter to 5 meters. This DAC is fully compliant with SFP28 Multi-Source Agreement (MSA), IEEE 802.3by 25GBASE-CR and 25GAUI standard. The twin-axial copper cable's wire gauge is 30AWG and pre-terminated with MSA compliant 20-pin edge type connectors. MSA memory map are accessible via 2-wire Interface (TWI/I2C). Our DACs are factory pre-programmed for compatibility, perform identically to original Cisco SFP-H25G-CU1M direct attach cables.
