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.

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

The 0.5m (2ft) length is suited to closely aligned ports where excessive slack would obstruct airflow or complicate dressing. Measure the actual port-to-port path before choosing 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top)-800G-DAC-0.5M2FT; even a short assembly must retain the specified bend radius and should never be pulled tight behind the equipment.

Position Within the Length Range

800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top)-800G-DAC-0.5M2FT 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 2x 400G OSFP (IHS/Finned Top)-800G-DAC-1M3FT at 1m (3ft), adding 0.5m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

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 30AWG conductors, PVC jacket, minimum bend radius 34.5mm. 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 2x 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.

Generic Compatibility and Factory Testing

The assembly is configured for equipment that recognizes 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top)-800G-DAC-0.5M2FT. Before shipment, we inspect both connectors and verify identification, link establishment and electrical continuity, link stability and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

Ordering Information

This product is ordered as 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top)-800G-DAC-0.5M2FT in 0.5m (2ft). 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.

Frequently Asked Questions

Is this an original equipment manufacturer cable?

No. It is manufactured by HT under our own manufacturer identity.

Can I use it between different speeds or interface types?

Only when both hosts explicitly support the same data rate, lane mapping and breakout configuration. Mechanical fit alone is not proof of interoperability.

What information should I provide for a compatibility check?

Provide the host manufacturer, equipment model, port type, hardware revision and software release, together with the OEM part number and required quantity.

Does this page include more than one cable length?

No. This page is dedicated to 0.5m (2ft) and part number 800G OSFP (IHS/Finned Top) to 2x 400G OSFP (IHS/Finned Top)-800G-DAC-0.5M2FT. Other lengths have their own part numbers and product pages.

Quality Assurance and Packaging

Before packing, our team checks the cable jacket, connector boots, latches and identification of each assembly. The cable is then secured in a loose coil and protected against dust and connector impact. Neutral packaging, customer part-number labels and project-specific carton lists can be supplied on request.

Shipping and Lead Time

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.
