NVIDIA/Mellanox MCP7Y70-H01A Compatible 400G OSFP 8 x 50G PAM4 IHS/Finned Top to 4 x 100G QSFP56 2 x 50G PAM4 InfiniBand HDR Passive Copper Breakout Cable, 1.5m (5ft)

This HT cable matches the MCP7Y70-H01A requirement for NVIDIA/Mellanox equipment. The 1.5m (5ft) assembly supports 400G operation and provides a factory-terminated passive copper link without separate optical modules or patch cords; its complete electrical and mechanical details are listed below.

The listed modulation format is 8x 50G-PAM4 to Quad 2x 50G-PAM4. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.

The additional half metre beyond a one-metre assembly gives MCP7Y70-H01A useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.

MCP7Y70-H01A occupies the middle of this family between MCP7Y70-H001 at 1m (3ft) and MCP7Y70-H002 at 2m (7ft). 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.

The rated power consumption is 0.1W (OSFP 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.

This assembly uses 28AWG 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 OSFP MSA, IEEE 802.3cd, CMIS v4.0. Confirm that the host firmware and port configuration support the same operating mode.

The OSFP (IHS/Finned Top) to 4x 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.

Our compatibility setup for NVIDIA/Mellanox MCP7Y70-H01A is checked together with the physical 1.5m (5ft) assembly. Factory verification covers connector condition, host identification, error-free link establishment and electrical continuity, link stability and diagnostic readouts. Providing the exact host model and firmware release helps us identify platform-specific requirements before production.

This product is ordered as MCP7Y70-H01A in 1.5m (5ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

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.

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.
