H3C QSFP56-200G-D-DAC-3M Compatible 200G QSFP56 4 x 50G PAM4 Passive Copper Twinax Cable, 3m (10ft)

This 3m (10ft) DAC cable is built for H3C equipment requiring the QSFP56-200G-D-DAC-3M interface. The 200Gbps link uses QSFP56 to QSFP56 and is supplied as one complete tested assembly.

OEM Part Number: QSFP56-200G-D-DAC-3MHT Part Number: QSFP56-200G-D-DAC-3M

Product Highlights

• Compatible alternative to H3C QSFP56-200G-D-DAC-3M
• 200G connectivity at 200Gbps
• Interface configuration: QSFP56 to QSFP56
• Fixed length and part number: 3m (10ft), QSFP56-200G-D-DAC-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.

QSFP56-200G-D-DAC-3M is the longest of 3 verified length options in this family. Compared with QSFP56-200G-D-DAC-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.

The HT cable carries the compatibility configuration associated with QSFP56-200G-D-DAC-3M, while its mechanical assembly remains the fixed 3m (10ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new H3C software can request a pre-order check.

Quote HT part number QSFP56-200G-D-DAC-3M with the required quantity. The 3m (10ft) 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.
