QSFP-DD to 8x SFP28-200G-DAC-1.5M5FT 200G QSFP-DD 8 x 25G NRZ to 8 x 25G SFP28 25G NRZ Passive Copper Breakout Cable, 1.5m (5ft)

Designed for hosts that recognize QSFP-DD to 8x SFP28-200G-DAC-1.5M5FT, this QSFP-DD to 8x SFP28 cable delivers 200G transmission over a fixed 1.5m (5ft) assembly. Its DAC construction provides a factory-terminated passive copper link without separate optical modules or patch cords.

The listed modulation format is QSFP-DD-8x 25G-NRZSFP28-25G-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.

QSFP-DD to 8x SFP28-200G-DAC-1.5M5FT occupies the middle of this family between QSFP-DD to 8x SFP28-200G-DAC-1M3FT at 1m (3ft) and QSFP-DD to 8x SFP28-200G-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.

The rated power consumption is 0.1W (QSFP-DD End)0.1W (SFP28 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.

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 22.5mm. 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.

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include QSFP-DD MSA, SFF-8432, IEEE 802.3bs-200GAUI-8, IEEE802.3by-25GAUI, CMIS 4.0, SFF-8472. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP-DD to 8x SFP28 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 8x SFP28-200G-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.

Our compatibility setup for Generic QSFP-DD to 8x SFP28-200G-DAC-1.5M5FT is checked together with the physical 1.5m (5ft) 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.

Use part number QSFP-DD to 8x SFP28-200G-DAC-1.5M5FT for the 1.5m (5ft) 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.

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.
