QSFP28 to QSFP28-100G-DAC-1M3FT 100G QSFP28 4 x 25G NRZ Active Copper Twinax Cable, 1m (3ft)

The QSFP28 to QSFP28-100G-DAC-1M3FT cable offers a direct QSFP28 to QSFP28 connection at 100Gbps. Its 1m (3ft) length and DAC construction are intended for multi-vendor equipment, with no separate transceiver-and-patch-cord assembly required.

OEM Part Number: QSFP28 to QSFP28-100G-DAC-1M3FTHT Part Number: QSFP28 to QSFP28-100G-DAC-1M3FT

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.

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.

At 1m (3ft), QSFP28 to QSFP28-100G-DAC-1M3FT is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

The rated power consumption is 1.5W. 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.

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 33mm. 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-8665. Confirm that the host firmware and port configuration support the same operating mode.

The HT cable carries the compatibility configuration associated with QSFP28 to QSFP28-100G-DAC-1M3FT, while its mechanical assembly remains the fixed 1m (3ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Generic software can request a pre-order check.

Quote HT part number QSFP28 to QSFP28-100G-DAC-1M3FT with the required quantity. The 1m (3ft) 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.

Every QSFP28 to QSFP28-100G-DAC-1M3FT compatible assembly undergoes link testing, compatibility verification and visual inspection. The 1m (3ft) 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.
