OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-3M10FT 400G OSFP 8 x 50G PAM4 IHS/Finned Top to 2 x 200G QSFP56 4 x 50G PAM4 Passive Copper Breakout Cable, 3m (10ft)

With a fixed 3m (10ft) cable and OSFP (IHS/Finned Top) to 2x QSFP56, the OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-3M10FT compatible assembly simplifies 400G deployment. It is manufactured and tested by HT for multi-vendor equipment.

OEM Part Number: OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-3M10FTHT Part Number: OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-3M10FT

Product Highlights

• HT-manufactured DAC assembly in 3m (10ft)
• 400G connectivity at 400Gbps
• Interface configuration: OSFP (IHS/Finned Top) to 2x QSFP56
• Fixed length and part number: 3m (10ft), OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-3M10FT
• Cable construction: Passive Twinax
• Conductor specification: 28AWG
• Maximum power consumption: 0.1W (OSFP End) 0.1W (QSFP56 Per End)
• Minimum bend radius: 40.5mm

The rated power consumption is 0.1W (OSFP End) 0.1W (QSFP56 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 400G Ethernet. Listed interface and protocol references include OSFP MSA, CMISRev4.0, IEEE802.3cd, SFF-8436, SFF-8665, SFF-8679, SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.

The OSFP (IHS/Finned Top) to 2x QSFP56 configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

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 2x QSFP56-400G-DAC-3M10FT is the longest of 8 verified length options in this family. Compared with CAB-O-2Q-400G-3M at 3m (10ft), it provides 0m 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.

Our compatibility setup for Generic OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-3M10FT is checked together with the physical 3m (10ft) assembly. Factory verification covers connector condition, host identification, error-free link establishment and electrical continuity, link stability and diagnostic readouts. Providing the exact host model and firmware release helps us identify platform-specific requirements before production.

Quote HT part number OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-3M10FT with the required quantity. The 3m (10ft) 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.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
