OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1M3FT 400G OSFP 8 x 50G PAM4 IHS/Finned Top to 2 x 200G QSFP56 4 x 50G PAM4 Passive Copper Breakout Cable, 1m (3ft)

Designed for hosts that recognize OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1M3FT, this OSFP (IHS/Finned Top) to 2x QSFP56 cable delivers 400G transmission over a fixed 1m (3ft) assembly. Its DAC construction provides a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1M3FTHT Part Number: OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1M3FT

• Interface configuration: OSFP (IHS/Finned Top) to 2x QSFP56
• Fixed length and part number: 1m (3ft), OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1M3FT
• Cable construction: Passive Twinax
• Conductor specification: 30AWG
• Maximum power consumption: 0.1W (OSFP End) 0.1W (QSFP56 Per End)
• Minimum bend radius: 34.5mm

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.

At 1m (3ft), OSFP (IHS/Finned Top) to 2x QSFP56-400G-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 2x QSFP56-400G-DAC-1M3FT occupies the middle of this family between CAB-O-2Q-400G-1M at 1m (3ft) and OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1.5M5FT at 1.5m (5ft). It adds 0m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

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 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.

Our compatibility setup for Generic OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1M3FT is checked together with the physical 1m (3ft) 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.

When ordering, specify OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1M3FT, cable length 1m (3ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

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.

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
