NVIDIA/Mellanox MCA7J70-N001 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, 1m (3ft)

With a fixed 1m (3ft) cable and OSFP (IHS/Finned Top) to 4x OSFP (RHS/Flat Top), the MCA7J70-N001 compatible assembly simplifies 800G deployment. It is manufactured and tested by HT for NVIDIA/Mellanox equipment.

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 30AWG conductors, PET jacket, minimum bend radius 23mm. 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.

At 1m (3ft), MCA7J70-N001 is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

MCA7J70-N001 is the shortest of 5 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is MCA7J70-N002 at 2m (7ft), adding 1m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

Compatibility is more than matching the OSFP (IHS/Finned Top) to 4x OSFP (RHS/Flat Top) shape. This assembly is prepared for hosts expecting MCA7J70-N001 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 MCA7J70-N001 for the 1m (3ft) 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.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
