Arista Networks CAB-Q-Q-1.5M Compatible 40G QSFP+ Passive Copper Cable, 1.5m (5ft)

Designed for hosts that recognize CAB-Q-Q-1.5M, this QSFP+ to QSFP+ cable delivers 40G transmission over a fixed 1.5m (5ft) assembly. Its DAC construction provides a factory-terminated passive copper link without separate optical modules or patch cords.

Product Highlights

• Compatible alternative to Arista Networks CAB-Q-Q-1.5M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to QSFP+
• Fixed length and part number: 1.5m (5ft), CAB-Q-Q-1.5M
• Conductor specification: 30AWG
• Minimum bend radius: 33.5mm

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 33.5mm. 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.

The additional half metre beyond a one-metre assembly gives CAB-Q-Q-1.5M useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.

CAB-Q-Q-1.5M occupies the middle of this family between CAB-Q-Q-1M at 1m (3ft) and CAB-Q-Q-2M at 2m (7ft). 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.

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 HT cable carries the compatibility configuration associated with CAB-Q-Q-1.5M, while its mechanical assembly remains the fixed 1.5m (5ft) 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.

Quote HT part number CAB-Q-Q-1.5M with the required quantity. The 1.5m (5ft) 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.
