The OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-2.5M8FT cable offers a direct OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top) connection at 400Gbps. Its 2.5m (8ft) length and DAC construction are intended for multi-vendor equipment, with no separate transceiver-and-patch-cord assembly required.

Modulation Format8x 50G-PAM4

Signal and Lane Configuration

The listed modulation format is 8x 50G-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.

Power and Thermal Planning

The rated power consumption is 0.1W 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 802.3cd 100GBase-CR2, CMIS 4.0. Confirm that the host firmware and port configuration support the same operating 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 2.5m (8ft) version is useful when a two-metre run would leave insufficient working slack. Before installation, check the complete horizontal and vertical path so that OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-2.5M8FT reaches both ports without tension at either connector.

Position Within the Length Range

OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-2.5M8FT occupies the middle of this family between OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-2M7FT at 2m (7ft) and OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-3M10FT at 3m (10ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

Generic Compatibility and Factory Testing

Each OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-2.5M8FT compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Generic platform should be included with the order.

Ordering Information

When ordering, specify OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-2.5M8FT, cable length 2.5m (8ft) 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.

Frequently Asked Questions

Is this an original equipment manufacturer cable?

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

Can the cable be folded to shorten its routing path?

No. Follow the specified minimum bend radius and route the 2.5m (8ft) assembly without tight folds, sharp edges or excessive cable ties.

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.

Quality Assurance and Packaging

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

Shipping and Lead Time

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
