Brocade 100G-Q28-Q28-C-0501 Compatible 100G QSFP28 4 x 25G NRZ Passive Copper Twinax Cable, 5m (16ft)

The 100G-Q28-Q28-C-0501 cable offers a direct QSFP28 to QSFP28 connection at 100Gbps. Its 5m (16ft) length and DAC construction are intended for Brocade equipment, with no separate transceiver-and-patch-cord assembly required.

OEM Part Number: 100G-Q28-Q28-C-0501HT Part Number: 100G-Q28-Q28-C-0501

Product Highlights

• Compatible alternative to Brocade 100G-Q28-Q28-C-0501
• 100G connectivity at 100Gbps
• Interface configuration: QSFP28 to QSFP28
• Fixed length and part number: 5m (16ft), 100G-Q28-Q28-C-0501
• Cable construction: Passive Twinax
• Conductor specification: 26AWG
• Maximum power consumption: ≤0.5W
• Minimum bend radius: 45mm

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 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 45mm. 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 5m (16ft) length gives 100G-Q28-Q28-C-0501 more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the DAC specification and host support must still match the intended link.

100G-Q28-Q28-C-0501 is the longest of 7 verified length options in this family. Compared with 100G-Q28-Q28-C-0301 at 3m (10ft), it provides 2m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.

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.

Compatibility is more than matching the QSFP28 to QSFP28 shape. This assembly is prepared for hosts expecting 100G-Q28-Q28-C-0501 and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

This product is ordered as 100G-Q28-Q28-C-0501 in 5m (16ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

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.

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.
