QSFP56 to 4x SFP56-200G-DAC-1M3FT 200G QSFP56 4 x 50G PAM4 to 4 x 50G SFP56 50G PAM4 Passive Copper Breakout Cable, 1m (3ft)

Use the QSFP56 to 4x SFP56-200G-DAC-1M3FT compatible assembly where a 200G connection is required between compatible ports. This page covers the 1m (3ft) version only, with its own HT part number, specifications and compatibility verification.

The listed modulation format is QSFP56-4x 50G-PAM4SFP56-50G-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.

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 35mm. 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 SFF-8661, SFF-8432, IEEE 802.3bs-200GAUI-4, IEEE802.3cd-50GAUI-1, SFP-8636, SFF-8472. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP56 to 4x SFP56 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 1m (3ft), QSFP56 to 4x SFP56-200G-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.

QSFP56 to 4x SFP56-200G-DAC-1M3FT occupies the middle of this family between QSFP56 to 4x SFP56-200G-DAC-0.5M2FT at 0.5m (2ft) and QSFP56 to 4x SFP56-200G-DAC-2M7FT at 2m (7ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 1m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The rated power consumption is 0.1W (QSFP56 End)0.1W (SFP56 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.

Each QSFP56 to 4x SFP56-200G-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.

Use part number QSFP56 to 4x SFP56-200G-DAC-1M3FT for the 1m (3ft) 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.

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.

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.
