QSFP28 to 4x SFP28-100G-DAC-7M23FT 100G QSFP28 4 x 25G NRZ to 4 x 25G SFP28 NRZ Active Copper Breakout Cable, 7m (23ft)

For short, high-density connections, this DAC cable combines 100G performance with a fixed 7m (23ft) cable run. It corresponds to Generic QSFP28 to 4x SFP28-100G-DAC-7M23FT and uses a factory-terminated passive copper link without separate optical modules or patch cords.

The listed modulation format is QSFP28-4x 25G-NRZ SFP28-1x 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.

The intended application is 100G/25G Ethernet. Listed interface and protocol references include QSFP28 MSA, SFP28 MSA, SFF-8665, SFF-8679, SFF-8472, SFF-8402. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP28 to 4x 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 extended 7m (23ft) reach supports connections across adjacent racks or between separated equipment rows. Secure the cable along its route, protect both ends from pull loads and preserve ventilation. The integrated DAC construction avoids a chain of separate modules and patch leads.

QSFP28 to 4x SFP28-100G-DAC-7M23FT occupies the middle of this family between QSFP28 to 4x SFP28-100G-DAC-5M16FT at 5m (16ft) and QSFP28 to 4x SFP28-100G-DAC-9M29FT at 9m (29ft). It adds 2m over the shorter option for extra routing clearance, while the next longer version adds another 2m. 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 1.8W. 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 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 44.5mm. 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.

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.

Quote HT part number QSFP28 to 4x SFP28-100G-DAC-7M23FT with the required quantity. The 7m (23ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, QSFP28 to 4x SFP28-100G-DAC-7M23FT and the 7m (23ft) length for easier inventory control.
