Arista Networks CAB-Q56-Q56-1.5M Compatible 200G QSFP56 4 x 50G PAM4 Passive Copper Twinax Cable, 1.5m (5ft)

Designed for hosts that recognize CAB-Q56-Q56-1.5M, this QSFP56 to QSFP56 cable delivers 200G 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.

OEM Part Number: CAB-Q56-Q56-1.5MHT Part Number: CAB-Q56-Q56-1.5M

Product Highlights

• Compatible alternative to Arista Networks CAB-Q56-Q56-1.5M
• 200G connectivity at 200Gbps
• Interface configuration: QSFP56 to QSFP56
• Fixed length and part number: 1.5m (5ft), CAB-Q56-Q56-1.5M
• Cable construction: Passive Twinax
• Conductor specification: 30AWG
• Maximum power consumption: 0.03W Per End
• Minimum bend radius: 39mm

The rated power consumption is 0.03W Per End. Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

This assembly uses 30AWG conductors, PVC jacket, minimum bend radius 39mm. 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 IEEE802.3cd, SFF-8436. 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 additional half metre beyond a one-metre assembly gives CAB-Q56-Q56-1.5M 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-Q56-Q56-1.5M occupies the middle of this family between CAB-Q56-Q56-1M at 1m (3ft) and CAB-Q56-Q56-2M 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.

Compatibility is more than matching the QSFP56 to QSFP56 shape. This assembly is prepared for hosts expecting CAB-Q56-Q56-1.5M and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

This product is ordered as CAB-Q56-Q56-1.5M in 1.5m (5ft). 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.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, CAB-Q56-Q56-1.5M and the 1.5m (5ft) length for easier inventory control.

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.
