Arista Networks CAB-Q-Q-2M Compatible 40G QSFP+ Passive Copper Cable, 2m (7ft)

The CAB-Q-Q-2M cable offers a direct QSFP+ to QSFP+ connection at 40Gbps. Its 2m (7ft) length and DAC construction are intended for Arista Networks equipment, with no separate transceiver-and-patch-cord assembly required.

OEM Part Number: CAB-Q-Q-2MHT Part Number: CAB-Q-Q-2M

Product Highlights

• Compatible alternative to Arista Networks CAB-Q-Q-2M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to QSFP+
• Fixed length and part number: 2m (7ft), CAB-Q-Q-2M
• 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.

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.

CAB-Q-Q-2M provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.

CAB-Q-Q-2M occupies the middle of this family between CAB-Q-Q-1.5M at 1.5m (5ft) and CAB-Q-Q-3m at 3m (10ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 1m. 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.

The HT cable carries the compatibility configuration associated with CAB-Q-Q-2M, while its mechanical assembly remains the fixed 2m (7ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Arista Networks software can request a pre-order check.

This product is ordered as CAB-Q-Q-2M in 2m (7ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

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.
