NVIDIA/Mellanox MCP7F60-W04 Compatible 400G QSFP-DD 8 x 50G PAM4 to 4 x 100G QSFP56 2 x 50G PAM4 Ethernet Active Copper Breakout Cable, 4m (13ft)
For buyers working from an equipment parts list, MCP7F60-W04 identifies more than a connector style. It refers here to a 4m (13ft) ACC cable for NVIDIA/Mellanox hosts, supporting 400G operation with QSFP-DD to 4x QSFP56. The sections below separate the OEM cross-reference, physical specification and HT factory checks for straightforward purchasing review.

Signal and Lane Configuration
The listed modulation format is 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.
Procurement and Port-Mapping Review
A useful purchase order should identify the host platform, the expected OEM code and the exact cable length as separate pieces of information. This prevents a physically similar assembly from being substituted when the port identification or reach is different. For mixed-length installations, prepare one order line per part number and reconcile each delivered cable with its intended pair of ports. For this assembly, the listed conductor specification is 28 AWG; the minimum bend radius is 80mm; the stated power consumption is ＜0.1W; the jacket material is PVC.
Power and Thermal Planning
The rated power consumption is ＜0.1W. 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.
Cable Construction and Routing
This assembly uses 28 AWG conductors, PVC jacket, minimum bend radius 80mm. 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.
Network and Protocol Considerations
The intended application is determined by the host interface and protocol support. Listed interface and protocol references include QSFP-DD MSASFF-8679SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.
Breakout Port Mapping
The QSFP-DD 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.
Length Selection and Installation Planning
The 4m (13ft) length gives MCP7F60-W04 more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the ACC specification and host support must still match the intended link.
Position Within the Length Range
MCP7F60-W04 occupies the middle of this family between MCP7F60-W03 at 3m (10ft) and MCP7F60-W05 at 5m (16ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 1m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.
NVIDIA/Mellanox Compatibility and Factory Testing
Our procurement-oriented compatibility check begins with the OEM reference and ends with a live host link. We record the physical length separately from the identification configuration, so the cable supplied for this page remains the stated version rather than a generic length substitute. Where supported by the host, link stability and diagnostic indications are reviewed together with the established link.
Ordering Information
For a clear bill of materials, quote the OEM reference, HT part number, length and quantity on the same line. Add the switch or server model and software release when a pre-order review is required; project labels can repeat those details for receiving and installation teams. Keep MCP7F60-W04 associated with 4m (13ft) throughout the order and receiving record.
Quality Assurance and Packaging
Before packing, the assembly is checked for connector condition, identification and link operation. Cables for multi-line orders can be labelled and grouped by part number, making it easier to match each length to the procurement record without opening every protective bag. Volume orders can include customer references on the labels and carton list.
Frequently Asked Questions
Is this an original NVIDIA/Mellanox cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies NVIDIA/Mellanox MCP7F60-W04.
Does this order code cover multiple lengths?
No. MCP7F60-W04 refers here to 4m (13ft). Every other verified length has a separate part number and page in the length list.
Are separate transceivers or patch leads required?
No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.
Can excess cable be folded into a compact bundle?
No. Use a supported, bend-safe service loop and observe the listed minimum bend radius. Do not crease the cable or tighten ties around the connector boots.
Shipping and Lead Time
Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.
