Dell DAC-Q56-200G-3M Compatible 200G QSFP56 4 x 50G PAM4 Passive Copper Twinax Cable, 3m (10ft)

This 3m (10ft) DAC cable is built for Dell equipment requiring the DAC-Q56-200G-3M interface. The 200Gbps link uses QSFP56 to QSFP56 and is supplied as one complete tested assembly.

OEM Part Number: DAC-Q56-200G-3MHT Part Number: DAC-Q56-200G-3M

Product Highlights

• Compatible alternative to Dell DAC-Q56-200G-3M
• 200G connectivity at 200Gbps
• Interface configuration: QSFP56 to QSFP56
• Fixed length and part number: 3m (10ft), DAC-Q56-200G-3M
• Cable construction: Passive Twinax
• Conductor specification: 26AWG
• Maximum power consumption: 0.03W Per End
• Minimum bend radius: 44.5mm

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.

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.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

DAC-Q56-200G-3M is the longest of 5 verified length options in this family. Compared with DAC-Q56-200G-2M at 2m (7ft), it provides 1m 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.

This assembly uses 26AWG conductors, PVC jacket, minimum bend radius 44.5mm. 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 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.

Each DAC-Q56-200G-3M compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Dell platform should be included with the order.

This product is ordered as DAC-Q56-200G-3M in 3m (10ft). 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.

Before packing, our team checks the cable jacket, connector boots, latches and identification of each assembly. The cable is then secured in a loose coil and protected against dust and connector impact. Neutral packaging, customer part-number labels and project-specific carton lists can be supplied on request.

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.
