Extreme Networks 10GB-4-C05-QSFP Compatible QSFP+ to 4SFP+ Passive Breakout Copper Cable, 5m (16ft)

The HT-manufactured 10GB-4-C05-QSFP compatible cable provides 40G connectivity for Extreme Networks equipment. This 5m (16ft) 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.

OEM Part Number: 10GB-4-C05-QSFPHT Part Number: 10GB-4-C05-QSFP

Product Highlights

• Compatible alternative to Extreme Networks 10GB-4-C05-QSFP
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to 4 SFP+
• Fixed length and part number: 5m (16ft), 10GB-4-C05-QSFP
• Conductor specification: 26AWG
• Minimum bend radius: 26mm

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 26mm. 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 determined by the host interface and protocol support. Listed interface and protocol references include SFF-8436, SFF-8431 and QSFP+ MSA. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP+ to 4 SFP+ configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

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 10GB-4-C05-QSFP 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.

10GB-4-C05-QSFP is the longest of 6 verified length options in this family. Compared with 10GB-4-C04-QSFP at 4m (13ft), it provides 1m 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.

Compatibility is more than matching the QSFP+ to 4 SFP+ shape. This assembly is prepared for hosts expecting 10GB-4-C05-QSFP 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 10GB-4-C05-QSFP 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.

Before packing, our team checks the cable jacket, connector boots, latches and identification of each assembly. The cable is then secured in a loose coil and protected against dust and connector impact. Neutral packaging, customer part-number labels and project-specific carton lists can be supplied on request.

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.
