2m (6.56ft) Arista Networks CAB-D-2Q-400G-2M Compatible 400G QSFP-DD to 2x200G QSFP56 PAM4 Passive Direct Attach Twinax Breakout Copper Cable

2m (6.56ft) Arista Networks CAB-D-2Q-400G-2M Compatible 400G QSFP-DD to 2x200G QSFP56 PAM4 Passive Direct Attach Twinax Breakout Copper Cable

Arista Networks CAB-D-2Q-400G-2M compatible DAC is a passive 2x 200Gbps QSFP-DD to 2 QSFP56 direct attach breakout cable for use in 200GBASE Ethernet. QSFP-DD breakout DAC provides 2x 200Gb/s throughput for 2m interconnection with high speed twin-axial copper cable. Standard length options cover from 0.5 meters to 2.5 meters. The breakout DAC cable splits 2x 200 Gbps PAM4 signals from QSFP-DD into QSFP56. It also supports 2x 100 Gbps NRZ fanout application. This DAC is fully compliant with QSFP-DD Multi-Source Agreement (MSA), IEEE 802.3cd 200GBASE-CR4 and 200GAUI-4 standard. The twin-axial copper cable's wire gauge is 28AWG and pre-terminated with MSA compliant 76-pin edge type connectors. MSA memory map are accessible via 2-wire Interface (TWI/I2C). Our breakout DACs are factory pre-programmed for compatibility, perform identically to original Arista Networks CAB-D-2Q-400G-2M direct attach cables.
