MCA7J75-N005NVIDIA/Mellanox MCA7J75-N005 Compatible 800G Twin-port OSFP 8 x 100G PAM4 IHS/Finned Top to 4 x 200G QSFP112 2 x 100G PAM4 InfiniBand NDR Active Copper Breakout Cable, 5m (16ft)
For densely populated equipment, the fixed 5m (16ft) version of NVIDIA/Mellanox MCA7J75-N005 offers a clearly defined 800G link without separate optical modules or patch cords. The ACC assembly uses OSFP (IHS/Finned Top) to 4x QSFP112; its power, mechanical and diagnostic details are listed where supplied so port density and cable management can be assessed together.

Signal and Lane Configuration
The listed modulation format is OSFP-8x 100G-PAM4QSFP112-2x 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.
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 26AWG; the minimum bend radius is 32.5mm; the stated power consumption is 1.7W (OSFP End)0.3W (QSFP112 Per End); the jacket material is PET.
Power and Thermal Planning
The rated power consumption is 1.7W (OSFP End)0.3W (QSFP112 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 26AWG conductors, PET jacket, minimum bend radius 32.5mm. 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 determined by the host interface and protocol support. Listed interface and protocol references include OSFP MSA Rev5.0, QSFP112 MSA, IEEE 802.3ck, CMIS 5.0. Confirm that the host firmware and port configuration support the same operating mode.
Breakout Port Mapping
The OSFP (IHS/Finned Top) to 4x QSFP112 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 5m (16ft) length gives MCA7J75-N005 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
MCA7J75-N005 is the longest of 5 verified length options in this family. Compared with MCA7J75-N004 at 4m (13ft), it provides 1m 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.
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. Neutral packaging and customer-specific packing documentation are available on request.
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 5m (16ft); 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 MCA7J75-N005.
Will any matching connector operate at the same speed?
Not necessarily. Both hosts must support the stated rate, identification, lane mapping and any required breakout configuration; mechanical compatibility alone is insufficient.
What details assist a compatibility review?
Provide the equipment manufacturer, model, port type, hardware revision and software release, together with the OEM reference, required length and quantity.
How should an unused assembly be stored?
Protect both connector ends, keep the cable in a loose bend-safe coil and retain its part-number label so the length and compatibility identity remain traceable.
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.
