Arista CAB-D-2Q-200G-1M | 200G QSFP-DD to 2x 100G QSFP CR4 DAC Cable, 1m

Q: What does the CAB-D-2Q-200G-1M cable do?
A: It breaks out a single 200G QSFP-DD port into two independent 100G QSFP28 connections, allowing a 200G switch port to connect to two separate 100G devices simultaneously. This is commonly used in spine-to-leaf or switch-to-server cabling in data centre environments.

Q: Is this an active or passive cable?
A: This is a passive direct attach copper (DAC) cable. It contains no active optical or electrical components, which means it draws no power from the host port, produces no heat, and offers the lowest possible latency for short-reach connections.

Q: What is the maximum supported cable length?
A: This variant is 1 metre in length, suited for within-rack connections. Passive DAC cables are typically limited to 1–3 metres; for longer runs, active copper (ACC) or optical solutions would be required.

Q: Which Arista switches are compatible with this cable?
A: The CAB-D-2Q-200G-1M is designed for Arista switches with QSFP-DD 200G ports, such as those in the 7050CX3, 7060CX2, and 7800 series, paired with devices featuring standard QSFP28 100G ports. Always verify compatibility with Arista's hardware compatibility list for your specific platform.

Q: Can I use this cable with non-Arista switches?
A: While the cable uses industry-standard QSFP-DD and QSFP28 connectors, vendor lock-in encoding may prevent use on non-Arista platforms. Some third-party switches support Arista-coded DAC cables, but compatibility should be confirmed with the switch vendor before purchase.
