NVIDIA/Mellanox MCP7Y50-N01A Compatible 800G OSFP 8 x 100G PAM4 IHS/Finned Top to 4 x 200G OSFP 2 x 100G PAM4 RHS/Flat Top InfiniBand NDR Passive Copper Breakout Cable, 1.5m (5ft)

The MCP7Y50-N01A cable on this page is the 1.5m (5ft) version for NVIDIA/Mellanox hosts requiring 800G operation. Its 800G OSFP (IHS/Finned Top) to 4x 200G OSFP (RHS/Flat Top) DAC construction reduces the connection to one factory-terminated assembly. Related lengths, brand cross-references and rack-integration notes support a precise high-density deployment.

Signal and Lane Configuration
The listed modulation format is 8x 100G PAM4 to Quad 2x 100G 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.
Position Within the Length Range
MCP7Y50-N01A occupies the middle of this family between MCP7Y50-N001 at 1m (3ft) and MCP7Y50-N002 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.
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 31mm; the stated power consumption is 0.1W (800G End)0.1W (200G Per End); the jacket material is PVC.
Power and Thermal Planning
The rated power consumption is 0.1W (800G End)0.1W (200G 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 31mm. 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 OSFP MSA, IEEE 802.3ck, CMIS v4.0. Confirm that the host firmware and port configuration support the same operating mode.
Breakout Port Mapping
The 800G OSFP (IHS/Finned Top) to 4x 200G OSFP (RHS/Flat Top) 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
The additional half metre beyond a one-metre assembly gives MCP7Y50-N01A 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.
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 1.5m (5ft); 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 MCP7Y50-N01A.
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. MCP7Y50-N01A refers here to 1.5m (5ft). 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
Available stock is normally prepared for dispatch within one to three working days, while larger production requirements are scheduled with the order. 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.
