NVIDIA/Mellanox MCA7J70-N004 Compatible 800G Twin-port OSFP 8 x 100G PAM4 IHS/Finned Top to 4 x 200G OSFP 2 x 100G PAM4 RHS/Flat Top Ethernet Active Copper Breakout Cable, 4m (13ft)

The HT-manufactured MCA7J70-N004 compatible cable provides 800G connectivity for NVIDIA/Mellanox equipment. This 4m (13ft) 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.

• Interface configuration: OSFP (IHS/Finned Top) to 4x OSFP (RHS/Flat Top)
• Fixed length and part number: 4m (13ft), MCA7J70-N004
• Cable construction: Active Breakout DAC (ACC)

• Minimum bend radius: 32.5mm

The listed modulation format is 8x100G-PAM4 to Quad 2x100G-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.

The rated power consumption is 1.7W (800G End)0.3W (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.

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 800G/200G Ethernet. Listed interface and protocol references include CMIS 5.0, IEEE 802.3ck, OSFP MSA Rev 5.0. Confirm that the host firmware and port configuration support the same operating mode.

The OSFP (IHS/Finned Top) to 4x 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 MCA7J70-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.

MCA7J70-N004 occupies the middle of this family between MCA7J70-N003 at 3m (10ft) and MCA7J70-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.

Our compatibility setup for NVIDIA/Mellanox MCA7J70-N004 is checked together with the physical 4m (13ft) assembly. Factory verification covers connector condition, host identification, error-free link establishment and electrical continuity, link stability and diagnostic readouts. Providing the exact host model and firmware release helps us identify platform-specific requirements before production.

Use part number MCA7J70-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 MCA7J70-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.
