Dell DAC-Q56-200G-0.5M Compatible 200G QSFP56 4 x 50G PAM4 Passive Copper Twinax Cable, 0.5m (2ft)

Use the DAC-Q56-200G-0.5M compatible assembly where a 200G connection is required between compatible ports. This page covers the 0.5m (2ft) version only, with its own HT part number, specifications and compatibility verification.

OEM Part Number: DAC-Q56-200G-0.5MHT Part Number: DAC-Q56-200G-0.5M

Product Highlights

• Compatible alternative to Dell DAC-Q56-200G-0.5M
• 200G connectivity at 200Gbps
• Interface configuration: QSFP56 to QSFP56
• Fixed length and part number: 0.5m (2ft), DAC-Q56-200G-0.5M
• 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.

The 0.5m (2ft) length is suited to closely aligned ports where excessive slack would obstruct airflow or complicate dressing. Measure the actual port-to-port path before choosing DAC-Q56-200G-0.5M; even a short assembly must retain the specified bend radius and should never be pulled tight behind the equipment.

DAC-Q56-200G-0.5M is the shortest of 5 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is DAC-Q56-200G-1M at 1m (3ft), adding 0.5m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

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.

Compatibility is more than matching the QSFP56 to QSFP56 shape. This assembly is prepared for hosts expecting DAC-Q56-200G-0.5M 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 DAC-Q56-200G-0.5M in 0.5m (2ft). 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.

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.
