Specifications

Signal and Lane Configuration

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.

Mixed-Vendor Network Operation

A mixed-vendor link should be documented at both ends, not treated as one generic connection. Confirm which OEM identity each host expects and whether the two ends use the same compatibility requirement. The related brand links below help locate equivalent-length assemblies, while the physical form factor and lane arrangement must still agree across the complete path. For this assembly, the listed conductor specification is 28AWG; the minimum bend radius is 40.5mm; the stated power consumption is 0.1W (800G End)0.1W (400G Per End); the jacket material is PVC.

Power and Thermal Planning

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.

Cable Construction and Routing

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.

Network and Protocol Considerations

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.

Breakout Port Mapping

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.

Passive Copper Operation

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.

Length Selection and Installation Planning

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.

Position Within the Length Range

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.

Generic Compatibility and Factory Testing

Testing addresses the brand-specific identification as well as the operating link and available diagnostics. The same physical cable family can require a different host identity for another equipment vendor, so the intended platform should be supplied when a deployment combines multiple brands or unusual hardware revisions. The check includes link stability and diagnostic indications, followed by a final inspection of both ends.

Ordering Information

For mixed-vendor projects, identify the equipment at both ends along with the OEM reference, length and quantity. Order each compatibility version under its own part number. If spare assemblies are required, list them separately so labels and test records remain unambiguous. Keep 800G OSFP (IHS/Finned Top) to 2× 400G OSFP (IHS/Finned Top)-800G-DAC-2M7FT associated with 2m (7ft) throughout the order and receiving record.

Quality Assurance and Packaging

Both ends are inspected and the complete assembly is powered up for a functional check before packing. Connectors are protected individually and the cable is secured without tight bends. Optional labels can distinguish host brand, OEM reference and length for easier spares management. Standard protective packing is used by default, with project documentation arranged when requested.
