H3C QSFP56-200G-D-DAC-1M Compatible 200G QSFP56 4 x 50G PAM4 Passive Copper Twinax Cable, 1m (3ft)

This 1m (3ft) DAC cable is built for H3C equipment requiring the QSFP56-200G-D-DAC-1M interface. The 200Gbps link uses QSFP56 to QSFP56 and is supplied as one complete tested assembly.

OEM Part Number: QSFP56-200G-D-DAC-1MHT Part Number: QSFP56-200G-D-DAC-1M

Product Highlights

• Compatible alternative to H3C QSFP56-200G-D-DAC-1M
• 200G connectivity at 200Gbps
• Interface configuration: QSFP56 to QSFP56
• Fixed length and part number: 1m (3ft), QSFP56-200G-D-DAC-1M
• 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.

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 1m (3ft), QSFP56-200G-D-DAC-1M is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

QSFP56-200G-D-DAC-1M is the shortest of 3 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 QSFP56-200G-D-DAC-2M at 2m (7ft), adding 1m 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.

Each QSFP56-200G-D-DAC-1M 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 H3C platform should be included with the order.

Quote HT part number QSFP56-200G-D-DAC-1M with the required quantity. The 1m (3ft) 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.

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, QSFP56-200G-D-DAC-1M and the 1m (3ft) length for easier inventory control.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
