Arista Networks CAB-Q-Q-1M Compatible 40G QSFP+ Passive Copper Cable, 1m (3ft)

For short, high-density connections, this DAC cable combines 40G performance with a fixed 1m (3ft) cable run. It corresponds to Arista Networks CAB-Q-Q-1M and uses a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: CAB-Q-Q-1MHT Part Number: CAB-Q-Q-1M

Product Highlights

• Compatible alternative to Arista Networks CAB-Q-Q-1M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to QSFP+
• Fixed length and part number: 1m (3ft), CAB-Q-Q-1M
• Conductor specification: 30AWG
• Minimum bend radius: 35mm

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 35mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include SFF-8436, QSFP+ MSA and IEEE 802.3ba. Confirm that the host firmware and port configuration support the same operating mode.

A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.

At 1m (3ft), CAB-Q-Q-1M is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

CAB-Q-Q-1M occupies the middle of this family between CAB-Q-Q-0.5M at 0.5m (2ft) and CAB-Q-Q-1.5M at 1.5m (5ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

Each CAB-Q-Q-1M compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Arista Networks platform should be included with the order.

Use part number CAB-Q-Q-1M for the 1m (3ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
