QSFP-DD to 2x QSFP28-200G-DAC-3M10FT 200G QSFP-DD 8 x 25G NRZ to 2 x 100G QSFP28 4 x 25G NRZ Passive Copper Breakout Cable, 3m (10ft)

This 3m (10ft) DAC cable is built for multi-vendor equipment requiring the QSFP-DD to 2x QSFP28-200G-DAC-3M10FT interface. The 200Gbps link uses QSFP-DD to 2x QSFP28 and is supplied as one complete tested assembly.

The listed modulation format is QSFP-DD-8x 25G-NRZQSFP28-4x 25G-NRZ. 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 28AWG conductors, PVC 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 QSFP-DD MSA, SFF-8661, IEEE 802.3bs-200GAUI-8, IEEE802.3bm-CAUI-4, CMIS 4.0, SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP-DD to 2x QSFP28 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.

QSFP-DD to 2x QSFP28-200G-DAC-3M10FT is the longest of 4 verified length options in this family. Compared with QSFP-DD to 2x QSFP28-200G-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 (QSFP-DD End)0.1W (QSFP28 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.

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 QSFP-DD to 2x QSFP28-200G-DAC-3M10FT, cable length 3m (10ft) 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.

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.

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.
