SFP-DD to 2x SFP56-100G-DAC-3M10FT 100G SFP-DD 2 x 50G PAM4 to 2 x SFP56 50G PAM4 Passive Copper Twinax Cable, 3m (10ft)

The HT-manufactured SFP-DD to 2x SFP56-100G-DAC-3M10FT compatible cable provides 100G 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.

The listed modulation format is SFP-DD-2x 50G-PAM4SFP56-1x 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.

SFP-DD to 2x SFP56-100G-DAC-3M10FT is the longest of 4 verified length options in this family. Compared with SFP-DD to 2x SFP56-100G-DAC-2M7FT at 2m (7ft), it provides 1m 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 rated power consumption is 0.1W. 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 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 28.8mm. 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 100G Ethernet, 128G Fibre Channel. Listed interface and protocol references include SFPDD: SFP-DD MSA, SFP-DD MIS, IEEE 802.3cdSFP56: SFF-8432, SFF-8402, SFF-8472, IEEE 802.3cd. Confirm that the host firmware and port configuration support the same operating mode.

The SFP-DD to 2x 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 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.

Compatibility is more than matching the SFP-DD to 2x SFP56 shape. This assembly is prepared for hosts expecting SFP-DD to 2x SFP56-100G-DAC-3M10FT and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

Use part number SFP-DD to 2x SFP56-100G-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.

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.
