QSFP28 to SFP28-100G-DAC-1M3FT 100G QSFP28 to 1 x 25G SFP28 Passive Copper Twinax Cable, 1m (3ft)

For short, high-density connections, this DAC cable combines 100G performance with a fixed 1m (3ft) cable run. It corresponds to Generic QSFP28 to SFP28-100G-DAC-1M3FT and uses a factory-terminated passive copper link without separate optical modules or patch cords.

The listed modulation format is QSFP28-1x 25G-NRZSFP28-1x 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.

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 SFP28-100G-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 ≤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.

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 30mm. 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 25G Ethernet, Data Centers. Listed interface and protocol references include QSFP28 MSA, SFP28 MSA, SFF-8665, SFF-8402, IEEE 802.3bj, IEEE 802.3by. Confirm that the host firmware and port configuration support the same operating mode.

The HT cable carries the compatibility configuration associated with QSFP28 to SFP28-100G-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.

When ordering, specify QSFP28 to SFP28-100G-DAC-1M3FT, cable length 1m (3ft) 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.

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 SFP28-100G-DAC-1M3FT and the 1m (3ft) length for easier inventory control.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
