QSFP-DD to 4x QSFP28-200G-DAC-1.5M5FT 200G QSFP-DD 8 x 25G NRZ to 4 x 50G QSFP28 2 x 25G NRZ Passive Copper Breakout Cable, 1.5m (5ft)

This 1.5m (5ft) DAC cable is built for multi-vendor equipment requiring the QSFP-DD to 4x QSFP28-200G-DAC-1.5M5FT interface. The 200G link uses QSFP-DD to 4x QSFP28 and is supplied as one complete tested assembly.

The listed modulation format is 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.

The QSFP-DD to 4x 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.

The additional half metre beyond a one-metre assembly gives QSFP-DD to 4x QSFP28-200G-DAC-1.5M5FT useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.

QSFP-DD to 4x QSFP28-200G-DAC-1.5M5FT occupies the middle of this family between QSFP-DD to 4x QSFP28-200G-DAC-1M3FT at 1m (3ft) and QSFP-DD to 4x QSFP28-200G-DAC-2M7FT at 2m (7ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

This assembly uses 28 AWG conductors, PVC jacket, minimum bend radius 10mm. 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 Rev. 5.0, CMIS Rev 4.0, IEEE 802.3cd. Confirm that the host firmware and port configuration support the same operating mode.

The assembly is configured for equipment that recognizes QSFP-DD to 4x QSFP28-200G-DAC-1.5M5FT. 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.

When ordering, specify QSFP-DD to 4x QSFP28-200G-DAC-1.5M5FT, cable length 1.5m (5ft) 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.

Every QSFP-DD to 4x QSFP28-200G-DAC-1.5M5FT compatible assembly undergoes link testing, compatibility verification and visual inspection. The 1.5m (5ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

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.
