Arista Networks CAB-Q-Q-7M Compatible 40G QSFP+ Passive Copper Cable, 7m (23ft)

With a fixed 7m (23ft) cable and QSFP+ to QSFP+, the CAB-Q-Q-7M compatible assembly simplifies 40G deployment. It is manufactured and tested by HT for Arista Networks equipment.

OEM Part Number: CAB-Q-Q-7MHT Part Number: CAB-Q-Q-7M

Product Highlights

• Compatible alternative to Arista Networks CAB-Q-Q-7M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to QSFP+
• Fixed length and part number: 7m (23ft), CAB-Q-Q-7M
• Conductor specification: 26AWG
• Minimum bend radius: 47.5mm

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 47.5mm. 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.

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 extended 7m (23ft) reach supports connections across adjacent racks or between separated equipment rows. Secure the cable along its route, protect both ends from pull loads and preserve ventilation. The integrated DAC construction avoids a chain of separate modules and patch leads.

CAB-Q-Q-7M is the longest of 7 verified length options in this family. Compared with CAB-Q-Q-5M at 5m (16ft), it provides 2m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.

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.

The assembly is configured for equipment that recognizes CAB-Q-Q-7M. 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.

Quote HT part number CAB-Q-Q-7M with the required quantity. The 7m (23ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
