OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-1M3FT 400G OSFP 8 x 50G PAM4 IHS/Finned Top Passive Copper Twinax Cable, 1m (3ft)

The HT-manufactured OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-1M3FT compatible cable provides 400G connectivity for multi-vendor equipment. This 1m (3ft) version is a factory-terminated passive copper link without separate optical modules or patch cords, with an exact part number and length that can be matched directly to the equipment requirement.

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.

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.

At 1m (3ft), OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-1M3FT is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-1M3FT is the shortest of 4 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 OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-2M7FT at 2m (7ft), adding 1m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

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.

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.

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.

Each OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-1M3FT 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.

Quote HT part number OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-1M3FT with the required quantity. The 1m (3ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-1M3FT and the 1m (3ft) length for easier inventory control.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
