For densely populated equipment, the fixed 3m (10ft) version of Generic OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-3M10FT offers a clearly defined 400G link without separate optical modules or patch cords. The DAC assembly uses OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top); its power, mechanical and diagnostic details are listed where supplied so port density and cable management can be assessed together.

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.

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

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

Position Within the Length Range

OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-3M10FT is the longest of 4 verified length options in this family. Compared with OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-2.5M8FT at 2.5m (8ft), it provides 0.5m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.

High-Density Rack Integration

In a densely populated rack, connector access and airflow are part of the link design. Choose the shortest length that follows the managed path comfortably, avoid tight bundles around the connector housings and preserve room for latch operation. Where power consumption is listed, include every populated interface in the host thermal budget rather than assessing a single cable in isolation. For this assembly, the listed conductor specification is 28AWG; the minimum bend radius is 40.5mm; the stated power consumption is 0.1W Per End; the jacket material is PVC.

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.

Quality Assurance and Packaging

Each assembly receives a visual connector inspection and functional link check before it is coiled and protected. Packaging is selected to avoid compressing the cable into a tight bundle, and optional rack-based labels help maintain an orderly installation when many identical interfaces are populated together. Volume orders can include customer references on the labels and carton list.

Ordering Information

Provide the exact part number, length, quantity and target interface density. For multi-rack projects, list each length separately and identify any preferred carton grouping. Host model and software information can be included for a compatibility review before production or dispatch. This page’s fixed configuration is 3m (10ft); another length must be quoted under its corresponding part number.

Generic Compatibility and Factory Testing

The assembly is evaluated for host recognition and stable link operation, with diagnostics checked where the interface provides them. This approach verifies more than electrical or optical continuity. Exact platform and firmware information remains valuable in high-density deployments because port mode and qualification policy can differ within the same connector family. Both connectors are examined before the operating test, which includes link stability and diagnostic indications.

Frequently Asked Questions

Is this an original equipment manufacturer cable?

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

How should an unused assembly be stored?

Protect both connector ends, keep the cable in a loose bend-safe coil and retain its part-number label so the length and compatibility identity remain traceable.

Can different brands be connected with the same assembly?

Only where both hosts explicitly support the complete interface and compatibility arrangement. Document each end and select the appropriate brand-specific product when required.

Does this order code cover multiple lengths?

No. OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-3M10FT refers here to 3m (10ft). Every other verified length has a separate part number and page in the length list.

Shipping and Lead Time

Available stock is normally prepared for dispatch within one to three working days, while larger production requirements are scheduled with the order. Worldwide courier services are available, with air or sea freight for consolidated shipments; freight-collect delivery and coordination with a customer’s logistics provider can be arranged.
