For equipment that specifies NVIDIA/Mellanox OSFP-800G-4OPC, this HT-manufactured DAC family offers 800G direct-attach connectivity with OSFP (IHS/Finned Top) to 4x OSFP (IHS/Finned Top). Rather than treating different OEM length codes as interchangeable, the available configurations below link to their own product pages. Mechanical details, installation planning and factory checks are included for engineering and purchasing review.

Rack Layout and Service Access

Plan the managed route before removing the connector protection. The cable should reach both ports without tension while leaving enough space to release the latches and service adjacent interfaces. Support the run through the intended managers, keep the connector boots clear of sharp edges and avoid storing excess length in a tight coil behind warm exhaust air. For this series, keep the interface rate, DAC construction and length-specific OEM reference together throughout that review.

Applications and Deployment

A passive DAC reduces the connection to one factory-terminated electrical assembly. This is useful where low latency, low interface power and a short managed route matter more than optical reach. Cable gauge, connector construction and host port settings still influence whether the complete link operates reliably. For this series, the listed interface is OSFP (IHS/Finned Top) to 4x OSFP (IHS/Finned Top) and the aggregate rate is 800G. The stated application is 800G/200G Ethernet.

Cable Construction and Routing

The specification table records the conductor specification is 30AWG; the jacket material is PVC (OFNR); the minimum bend radius is 26mm; the operating temperature is 0 to 70°C (32 to 158°F); the power consumption is 0.1W (800G End), 0.1W (200G Per End). Use those values when preparing the rack pathway and receiving checklist. Do not pull a connector by its cable, compress the run under tight ties or force excess length into a sharp coil. Connector protection should remain in place until the assembly is ready for insertion.

Quality Assurance and Packaging

The completed cable is inspected at both ends, functionally tested and coiled with bend-safe slack. Protective packaging keeps the latches and boots from taking impact, while optional project labels can identify the two endpoint locations for easier field service. Both connector ends are inspected as part of the complete assembly, and protective packing is selected to avoid tight bends during transport and storage.

NVIDIA/Mellanox Compatibility and Factory Testing

Compatibility is verified as part of a complete installation check: connector inspection, host identification and an operating link. The physical cable is evaluated together with the expected OEM identity, because a connector that fits is not sufficient evidence that the host will accept and operate the assembly correctly. Series-level inspection is followed by the exact length and OEM configuration selected for dispatch. Functional verification includes link establishment and diagnostic indications where the host exposes them.

Ordering Information

When requesting this assembly, include the exact part number and length together with the destination port types. For a rack installation, a simple port-to-port list helps us keep different lengths separate and allows any requested labels to correspond with the actual installation sequence. For this series, follow the corresponding length link, quote that exact OEM part number and keep different lengths on separate order lines. HT part number OSFP-800G-4OPC identifies the product family; the linked page provides the final length-specific identity.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.

Frequently Asked Questions

Is this an original NVIDIA/Mellanox cable?

No. It is an HT-manufactured compatible cable for equipment that specifies OSFP-800G-4OPC, not an original NVIDIA/Mellanox-branded product.

Are different lengths and OEM part numbers separate products?

Yes. Where a length has its own OEM reference, follow the corresponding link above and order that exact part number on its own line. Do not substitute another length only because the connector arrangement is the same.

Does this DAC cable require separate modules at each end?

No. The connector ends and cable form one complete direct-attach assembly. The ends are not detachable standalone transceivers, and the complete product is tested together.

What information helps confirm compatibility?

Provide the equipment manufacturer and model, port type, hardware revision and software release, together with the required OEM reference, length and quantity. Breakout projects should also identify the intended lane configuration.
