OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-3M10FT 400G OSFP 8 x 50G PAM4 IHS/Finned Top Passive Copper Twinax Cable, 3m (10ft)

The HT-manufactured OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-3M10FT compatible cable provides 400G connectivity for multi-vendor equipment. This 3m (10ft) 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.

• Interface configuration: OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)
• Fixed length and part number: 3m (10ft), OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-3M10FT
• Cable construction: Passive DAC
• Conductor specification: 28AWG
• Maximum power consumption: 0.1W Per End
• Minimum bend radius: 40.5mm

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.

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 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.

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.

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 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.

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.

The HT cable carries the compatibility configuration associated with OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-3M10FT, while its mechanical assembly remains the fixed 3m (10ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Generic software can request a pre-order check.

Use part number OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top)-400G-DAC-3M10FT for the 3m (10ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

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-3M10FT and the 3m (10ft) 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.
