Dell (DE) DAC-Q28-100G-2M Compatible 100G QSFP28 4 x 25G NRZ Passive Copper Twinax Cable, 2m (7ft)

The HT-manufactured DAC-Q28-100G-2M compatible cable provides 100G connectivity for Dell (DE) equipment. This 2m (7ft) version is a factory-terminated passive copper link without separate optical modules or patch cords, with an exact part number and length that can be matched directly to the equipment requirement.

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.

DAC-Q28-100G-2M provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.

DAC-Q28-100G-2M occupies the middle of this family between DAC-Q28-100G-1.5M at 1.5m (5ft) and DAC-Q28-100G-2.5M at 2.5m (8ft). 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 ≤0.5W. 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 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 assembly is configured for equipment that recognizes DAC-Q28-100G-2M. Before shipment, we inspect both connectors and verify identification, link establishment and electrical continuity, link stability and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

Quote HT part number DAC-Q28-100G-2M with the required quantity. The 2m (7ft) 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.

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.

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.
