NVIDIA/Mellanox MCA7J60-N004 Compatible 800G OSFP 8 x 100G PAM4 IHS/Finned Top to 2 x 400G OSFP 4 x 100G PAM4 RHS/Flat Top Ethernet Active Copper Breakout Cable, 4m (13ft)

This 4m (13ft) ACC cable is built for NVIDIA/Mellanox equipment requiring the MCA7J60-N004 interface. The 800Gbps link uses 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (RHS/Flat Top) and is supplied as one complete tested assembly.

• Minimum bend radius: 40mm

The listed modulation format is 8x 100G-PAM4 to Dual 4x 100G-PMA4. 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.

MCA7J60-N004 is the longest of 4 verified length options in this family. Compared with MCA7J60-N003 at 3m (10ft), 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.

The rated power consumption is 1.5W (800G End)/0.6W (400G 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 40mm. 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 800G/400G Ethernet. Listed interface and protocol references include OSFP MSA, CMIS 5.0, IEEE 802.3 ck. Confirm that the host firmware and port configuration support the same operating mode.

The 800G OSFP (IHS/Finned Top) to 2x 400G 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.

The 4m (13ft) length gives MCA7J60-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 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (RHS/Flat Top) shape. This assembly is prepared for hosts expecting MCA7J60-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.

Use part number MCA7J60-N004 for the 4m (13ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

Every MCA7J60-N004 compatible assembly undergoes link testing, compatibility verification and visual inspection. The 4m (13ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
