NVIDIA/Mellanox MCA7J75-N004 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, 4m (13ft)

This 4m (13ft) ACC cable is built for NVIDIA/Mellanox equipment requiring the MCA7J75-N004 interface. The 800Gbps link uses OSFP (IHS/Finned Top) to 4x QSFP112 and is supplied as one complete tested assembly.

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.

MCA7J75-N004 occupies the middle of this family between MCA7J75-N003 at 3m (10ft) and MCA7J75-N005 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.

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.

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.

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.

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.

The 4m (13ft) length gives MCA7J75-N004 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.

Compatibility is more than matching the OSFP (IHS/Finned Top) to 4x QSFP112 shape. This assembly is prepared for hosts expecting MCA7J75-N004 and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

Quote HT part number MCA7J75-N004 with the required quantity. The 4m (13ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

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.
