NVIDIA/Mellanox MCA7J60-N003 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, 3m (10ft)

The HT-manufactured MCA7J60-N003 compatible cable provides 800G connectivity for NVIDIA/Mellanox equipment. This 3m (10ft) version is an actively conditioned copper link for the stated high-speed interface, with an exact part number and length that can be matched directly to the equipment requirement.

OEM Part Number: MCA7J60-N003HT Part Number: MCA7J60-N003

• Fixed length and part number: 3m (10ft), MCA7J60-N003
• Cable construction: Active Breakout DAC (ACC)

• Minimum bend radius: 32.5mm

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.

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 30AWG 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 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.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

MCA7J60-N003 occupies the middle of this family between MCA7J60-N002 at 2m (7ft) and MCA7J60-N004 at 4m (13ft). 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.

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-N003 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.

This product is ordered as MCA7J60-N003 in 3m (10ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

Every MCA7J60-N003 compatible assembly undergoes link testing, compatibility verification and visual inspection. The 3m (10ft) 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.

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.
