Brocade 100G-Q28-Q28-C-0301 Compatible 100G QSFP28 4 x 25G NRZ Passive Copper Twinax Cable, 3m (10ft)

For short, high-density connections, this DAC cable combines 100G performance with a fixed 3m (10ft) cable run. It corresponds to Brocade 100G-Q28-Q28-C-0301 and uses a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: 100G-Q28-Q28-C-0301HT Part Number: 100G-Q28-Q28-C-0301

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.

100G-Q28-Q28-C-0301 occupies the middle of this family between 100G-Q28-Q28-C-02501 at 2.5m (8ft) and 100G-Q28-Q28-C-0501 at 5m (16ft). It adds 0.5m 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 ≤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.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

The assembly is configured for equipment that recognizes 100G-Q28-Q28-C-0301. 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.

Use part number 100G-Q28-Q28-C-0301 for the 3m (10ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

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, 100G-Q28-Q28-C-0301 and the 3m (10ft) length for easier inventory control.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
