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

800G OSFP (IHS/Finned Top) to 2× 400G OSFP (IHS/Finned Top)-800G-DAC-2M7FT is the shortest of 3 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 800G OSFP (IHS/Finned Top) to 2× 400G OSFP (IHS/Finned Top)-800G-DAC-2.5M8FT at 2.5m (8ft), adding 0.5m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

The rated power consumption is 0.1W (800G End)0.1W (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 28AWG conductors, PVC jacket, minimum bend radius 40.5mm. 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, IEEE 802.3ck, CMIS v4.0. Confirm that the host firmware and port configuration support the same operating mode.

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

A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.

800G OSFP (IHS/Finned Top) to 2× 400G OSFP (IHS/Finned Top)-800G-DAC-2M7FT provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.

Compatibility is more than matching the 800G OSFP (IHS/Finned Top) to 2× 400G OSFP (IHS/Finned Top) shape. This assembly is prepared for hosts expecting 800G OSFP (IHS/Finned Top) to 2× 400G OSFP (IHS/Finned Top)-800G-DAC-2M7FT 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.

When ordering, specify 800G OSFP (IHS/Finned Top) to 2× 400G OSFP (IHS/Finned Top)-800G-DAC-2M7FT, cable length 2m (7ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

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.

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.
