OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-1.5M5FT 400G OSFP 4 x 100G PAM4 RHS/Flat Top to 400G QSFP-DD 4 x 100G PAM4 Passive Copper Twinax Cable, 1.5m (5ft)

For short, high-density connections, this DAC cable combines 400G performance with a fixed 1.5m (5ft) cable run. It corresponds to Generic OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-1.5M5FT and uses a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-1.5M5FTHT Part Number: OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-1.5M5FT

Product Highlights

• HT-manufactured DAC assembly in 1.5m (5ft)
• 400G connectivity at 400Gbps
• Interface configuration: OSFP (RHS/Flat Top) to QSFP-DD
• Fixed length and part number: 1.5m (5ft), OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-1.5M5FT
• Cable construction: Passive Twinax
• Conductor specification: 28AWG
• Maximum power consumption: ≤0.1W
• Minimum bend radius: 40.5mm

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 intended application is 400G Ethernet. Listed interface and protocol references include IEEE 802.3cd, OSFP MSA, QSFP-DD MSA, CMIS Rev4.0, SFF-8417. 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.

The additional half metre beyond a one-metre assembly gives OSFP (RHS/Flat Top) to QSFP-DD-400G-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.

OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-1.5M5FT occupies the middle of this family between OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-1M3FT at 1m (3ft) and OSFP (RHS/Flat Top) to QSFP-DD-400G-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 28AWG conductors, PVC jacket, minimum bend radius 40.5mm. 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.

Each OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-1.5M5FT compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Generic platform should be included with the order.

When ordering, specify OSFP (RHS/Flat Top) to QSFP-DD-400G-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 OSFP (RHS/Flat Top) to QSFP-DD-400G-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.

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.
