Cisco Q56-200-CU50CM Compatible 200G QSFP56 4 x 50G PAM4 Passive Copper Twinax Cable, 0.5m (2ft)

The HT-manufactured Q56-200-CU50CM compatible cable provides 200G connectivity for Cisco equipment. This 0.5m (2ft) version is a factory-terminated passive copper link without separate optical modules or patch cords, with an exact part number and length that can be matched directly to the equipment requirement.

Product Highlights

• Compatible alternative to Cisco Q56-200-CU50CM
• 200G connectivity at 200Gbps
• Interface configuration: QSFP56 to QSFP56
• Fixed length and part number: 0.5m (2ft), Q56-200-CU50CM
• 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.

Q56-200-CU50CM 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 Q56-200-CU1M 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.

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 Q56-200-CU50CM; even a short assembly must retain the specified bend radius and should never be pulled tight behind the equipment.

Compatibility is more than matching the QSFP56 to QSFP56 shape. This assembly is prepared for hosts expecting Q56-200-CU50CM 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.

Quote HT part number Q56-200-CU50CM with the required quantity. The 0.5m (2ft) 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.

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
