NVIDIA/Mellanox MCP7H60-W02AR26 Compatible 400G QSFP-DD 8 x 50G PAM4 to 2 x 200G QSFP56 4 x 50G PAM4 Ethernet Passive Copper Breakout Cable, 2.5m (8ft)

With a fixed 2.5m (8ft) cable and QSFP-DD to 2x QSFP56, the MCP7H60-W02AR26 compatible assembly simplifies 400G deployment. It is manufactured and tested by HT for NVIDIA/Mellanox equipment.

OEM Part Number: MCP7H60-W02AR26HT Part Number: MCP7H60-W02AR26

Product Highlights

• Compatible alternative to NVIDIA/Mellanox MCP7H60-W02AR26
• 400G connectivity at 400Gbps
• Interface configuration: QSFP-DD to 2x QSFP56
• Fixed length and part number: 2.5m (8ft), MCP7H60-W02AR26
• Cable construction: Passive Twinax
• Conductor specification: 28AWG
• Maximum power consumption: 0.1W (QSFP-DD End) 0.1W (QSFP56 Per End)
• Minimum bend radius: 39.5mm

The rated power consumption is 0.1W (QSFP-DD End) 0.1W (QSFP56 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 intended application is 400G Ethernet. Listed interface and protocol references include IEEE802.3Bj, By, IEEE802.3CD, SFF-8679, SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP-DD to 2x QSFP56 configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

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 2.5m (8ft) version is useful when a two-metre run would leave insufficient working slack. Before installation, check the complete horizontal and vertical path so that MCP7H60-W02AR26 reaches both ports without tension at either connector.

MCP7H60-W02AR26 occupies the middle of this family between MCP7H60-W002R26 at 2m (7ft) and MCP7H60-W003R26 at 3m (10ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

This assembly uses 28AWG conductors, PVC jacket, minimum bend radius 39.5mm. 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.

Compatibility is more than matching the QSFP-DD to 2x QSFP56 shape. This assembly is prepared for hosts expecting MCP7H60-W02AR26 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.

Use part number MCP7H60-W02AR26 for the 2.5m (8ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

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, MCP7H60-W02AR26 and the 2.5m (8ft) length for easier inventory control.

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.
