Arista Networks CAB-Q-Q-5M Compatible 40G QSFP+ Passive Copper Cable, 5m (16ft)

For short, high-density connections, this DAC cable combines 40G performance with a fixed 5m (16ft) cable run. It corresponds to Arista Networks CAB-Q-Q-5M and uses a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: CAB-Q-Q-5MHT Part Number: CAB-Q-Q-5M

Product Highlights

• Compatible alternative to Arista Networks CAB-Q-Q-5M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to QSFP+
• Fixed length and part number: 5m (16ft), CAB-Q-Q-5M
• Conductor specification: 26AWG
• Minimum bend radius: 40mm

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 40mm. 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 5m (16ft) length gives CAB-Q-Q-5M more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the DAC specification and host support must still match the intended link.

CAB-Q-Q-5M occupies the middle of this family between CAB-Q-Q-3m at 3m (10ft) and CAB-Q-Q-7M at 7m (23ft). It adds 2m over the shorter option for extra routing clearance, while the next longer version adds another 2m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

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.

The assembly is configured for equipment that recognizes CAB-Q-Q-5M. Before shipment, we inspect both connectors and verify identification, link establishment and electrical continuity, link stability and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

When ordering, specify CAB-Q-Q-5M, cable length 5m (16ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Every CAB-Q-Q-5M compatible assembly undergoes link testing, compatibility verification and visual inspection. The 5m (16ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
