2.5m (8.20ft) Arista Networks CAB-Q-4S-100G-2.5M Compatible QSFP28 to 4 SFP28 DAC 25GBASE-CR 4x 25Gbps Passive Direct Attach Twinax Breakout Copper Cable

2.5m (8.20ft) Arista Networks CAB-Q-4S-100G-2.5M Compatible QSFP28 to 4 SFP28 DAC 25GBASE-CR 4x 25Gbps Passive Direct Attach Twinax Breakout Copper Cable

Arista Networks CAB-Q-4S-100G-2.5M compatible DAC is a passive 4x 25Gbps QSFP28 to 4 SFP28 direct attach breakout cable for use in 25GBASE Ethernet network. QSFP28 breakout DAC provides 4x 25.78Gb/s throughput for 2.5m interconnection with high speed twin-axial copper cable. This DAC is fully compliant with QSFP28/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 38/20-pin edge type connectors. The breakout DAC cable splits 4 branches of 25Gbps NRZ signals from QSFP28 into SFP28. Standard length options cover from 0.5 meters to 5 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 Arista Networks CAB-Q-4S-100G-2.5M direct attach cables.
