For densely populated equipment, the fixed 2m (7ft) version of NVIDIA/Mellanox MCP7Y60-H002 offers a clearly defined 400G link without separate optical modules or patch cords. The DAC assembly uses OSFP to 2x QSFP56; its power, mechanical and diagnostic details are listed where supplied so port density and cable management can be assessed together.

Power and Thermal Planning
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.
Cable Construction and Routing
This assembly uses 28AWG conductors, PVC jacket, minimum bend radius 40.5mm. 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.
Network and Protocol Considerations
The intended application is InfiniBand HDR. Listed interface and protocol references include OSFP MSA, CMISRev4.0, IEEE802.3cd, SFF-8436, SFF-8665, SFF-8679, SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.
Breakout Port Mapping
The OSFP 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.
Passive Copper Operation
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.
Length Selection and Installation Planning
MCP7Y60-H002 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.
Position Within the Length Range
MCP7Y60-H002 is the longest of 3 verified length options in this family. Compared with MCP7Y60-H01A 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.
High-Density Rack Integration
In a densely populated rack, connector access and airflow are part of the link design. Choose the shortest length that follows the managed path comfortably, avoid tight bundles around the connector housings and preserve room for latch operation. Where power consumption is listed, include every populated interface in the host thermal budget rather than assessing a single cable in isolation. For this assembly, the listed conductor specification is 28AWG; the minimum bend radius is 40.5mm; the stated power consumption is 0.1W (OSFP End) 0.1W (QSFP56 Per End); the jacket material is PVC.
Quality Assurance and Packaging
Each assembly receives a visual connector inspection and functional link check before it is coiled and protected. Packaging is selected to avoid compressing the cable into a tight bundle, and optional rack-based labels help maintain an orderly installation when many identical interfaces are populated together. Volume orders can include customer references on the labels and carton list.
Ordering Information
Provide the exact part number, length, quantity and target interface density. For multi-rack projects, list each length separately and identify any preferred carton grouping. Host model and software information can be included for a compatibility review before production or dispatch. This page’s fixed configuration is 2m (7ft); another length must be quoted under its corresponding part number.
NVIDIA/Mellanox Compatibility and Factory Testing
The assembly is evaluated for host recognition and stable link operation, with diagnostics checked where the interface provides them. This approach verifies more than electrical or optical continuity. Exact platform and firmware information remains valuable in high-density deployments because port mode and qualification policy can differ within the same connector family. The check includes link stability and diagnostic indications, followed by a final inspection of both ends.
Frequently Asked Questions
Is this an original NVIDIA/Mellanox cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies NVIDIA/Mellanox MCP7Y60-H002.
Can different brands be connected with the same assembly?
Only where both hosts explicitly support the complete interface and compatibility arrangement. Document each end and select the appropriate brand-specific product when required.
Does this order code cover multiple lengths?
No. MCP7Y60-H002 refers here to 2m (7ft). 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.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, with production quantities confirmed at order stage. 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.
