NVIDIA/Mellanox MCP7H50-H002R26 Compatible 200G QSFP56 4 x 50G PAM4 to 2 x 100G QSFP56 2 x 50G PAM4 InfiniBand HDR Passive Copper Breakout Cable, 2m (7ft)

For short, high-density connections, this DAC cable combines 200G performance with a fixed 2m (7ft) cable run. It corresponds to NVIDIA/Mellanox MCP7H50-H002R26 and uses a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: MCP7H50-H002R26HT Part Number: MCP7H50-H002R26

Product Highlights

• Compatible alternative to NVIDIA/Mellanox MCP7H50-H002R26
• 200G connectivity at 200Gbps
• Interface configuration: QSFP56 to 2 QSFP56
• Fixed length and part number: 2m (7ft), MCP7H50-H002R26
• Cable construction: Passive Twinax
• Conductor specification: 26AWG
• Maximum power consumption: 0.1W (200G End) 0.1W (100G Per End)
• Minimum bend radius: 30mm

The rated power consumption is 0.1W (200G End) 0.1W (100G 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.

MCP7H50-H002R26 is the longest of 4 verified length options in this family. Compared with MCP7H50-H01AR30 at 1.5m (5ft), it provides 0.5m 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 (OFNR) jacket, minimum bend radius 30mm. 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 IEEE 802.3cd, SFF-8665, SFF-8665. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP56 to 2 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.

MCP7H50-H002R26 provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.

Each MCP7H50-H002R26 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 NVIDIA/Mellanox platform should be included with the order.

When ordering, specify MCP7H50-H002R26, cable length 2m (7ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

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.
