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

Designed for hosts that recognize SFP-DD to SFP-DD-100G-DAC-1M3FT, this SFP-DD to SFP-DD cable delivers 100G transmission over a fixed 1m (3ft) assembly. Its DAC construction provides a factory-terminated passive copper link without separate optical modules or patch cords.

The listed modulation format is 2x 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 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 SFP-DD MSA, SFP-DD MIS, IEEE 802.3cd. Confirm that the host firmware and port configuration support the same operating 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 SFP-DD-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 SFP-DD-100G-DAC-1M3FT occupies the middle of this family between SFP-DD to SFP-DD-100G-DAC-0.5M2FT at 0.5m (2ft) and SFP-DD to SFP-DD-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.

The assembly is configured for equipment that recognizes SFP-DD to SFP-DD-100G-DAC-1M3FT. Before shipment, we inspect both connectors and verify identification, link establishment and electrical continuity, link stability and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

Use part number SFP-DD to SFP-DD-100G-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.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
