QSFP28 to QSFP28-100G-DAC-1.5M5FT 100G QSFP28 4 x 25G NRZ Passive Copper Twinax Cable, 1.5m (5ft)

For short, high-density connections, this DAC cable combines 100G performance with a fixed 1.5m (5ft) cable run. It corresponds to Generic QSFP28 to QSFP28-100G-DAC-1.5M5FT and uses a factory-terminated passive copper link without separate optical modules or patch cords.

The listed modulation format is 4x 25G-NRZ to 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 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 33.5mm. 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 100G Ethernet. Listed interface and protocol references include QSFP28 MSA, SFF-8662, IEEE 802.3. 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 QSFP28 to QSFP28-100G-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.

QSFP28 to QSFP28-100G-DAC-1.5M5FT occupies the middle of this family between QSFP28 to QSFP28-100G-DAC-0.5M2FT at 0.5m (2ft) and QSFP28 to QSFP28-100G-DAC-2M7FT at 2m (7ft). It adds 1m 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 ≤0.5W. 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.

Our compatibility setup for Generic QSFP28 to QSFP28-100G-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.

Quote HT part number QSFP28 to QSFP28-100G-DAC-1.5M5FT with the required quantity. The 1.5m (5ft) 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.

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.

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.
