SFP-DD to 2x SFP56-100G-DAC-1M3FT 100G SFP-DD 2 x 50G PAM4 to 2 x SFP56 50G PAM4 Passive Copper Twinax Cable, 1m (3ft)

This 1m (3ft) DAC cable is built for multi-vendor equipment requiring the SFP-DD to 2x SFP56-100G-DAC-1M3FT interface. The 100Gbps link uses SFP-DD to 2x SFP56 and is supplied as one complete tested assembly.

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.

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), SFP-DD to 2x SFP56-100G-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.

SFP-DD to 2x SFP56-100G-DAC-1M3FT occupies the middle of this family between SFP-DD to 2x SFP56-100G-DAC-0.5M2FT at 0.5m (2ft) and SFP-DD to 2x SFP56-100G-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. 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 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 23.6mm. 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.

Our compatibility setup for Generic SFP-DD to 2x SFP56-100G-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.

This product is ordered as SFP-DD to 2x SFP56-100G-DAC-1M3FT in 1m (3ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

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.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
