OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1.5M5FT 400G OSFP 8 x 50G PAM4 IHS/Finned Top to 2 x 200G QSFP56 4 x 50G PAM4 Passive Copper Breakout Cable, 1.5m (5ft)

Designed for hosts that recognize OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1.5M5FT, this OSFP (IHS/Finned Top) to 2x QSFP56 cable delivers 400G transmission over a fixed 1.5m (5ft) assembly. Its DAC construction provides a factory-terminated passive copper link without separate optical modules or patch cords.

• 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.

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.

The additional half metre beyond a one-metre assembly gives OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1.5M5FT useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.

OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1.5M5FT occupies the middle of this family between OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1M3FT at 1m (3ft) and CAB-O-2Q-400G-2M at 2m (7ft). It adds 0.5m 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 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.

For this Generic application, testing combines digital identification with actual traffic-link verification and electrical continuity, link stability and diagnostic readouts. Both ends are inspected for latch, boot and connector damage. If the project uses a specific hardware revision or a channelized port, send those details so that the intended configuration can be reviewed before shipment.

When ordering, specify OSFP (IHS/Finned Top) to 2x QSFP56-400G-DAC-1.5M5FT, cable length 1.5m (5ft) 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.

Before packing, our team checks the cable jacket, connector boots, latches and identification of each assembly. The cable is then secured in a loose coil and protected against dust and connector impact. Neutral packaging, customer part-number labels and project-specific carton lists can be supplied on request.

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.
