Brocade 40G-QSFP-4SFP-C-0401 Compatible 40G QSFP+ to 4 x 10G SFP+ Passive Copper Breakout Cable, 4m (13ft)

For short, high-density connections, this DAC cable combines 40G performance with a fixed 4m (13ft) cable run. It corresponds to Brocade 40G-QSFP-4SFP-C-0401 and uses a factory-terminated passive copper link without separate optical modules or patch cords.

OEM Part Number: 40G-QSFP-4SFP-C-0401HT Part Number: 40G-QSFP-4SFP-C-0401

Product Highlights

• Compatible alternative to Brocade 40G-QSFP-4SFP-C-0401
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to 4 SFP+
• Fixed length and part number: 4m (13ft), 40G-QSFP-4SFP-C-0401
• Conductor specification: 26AWG
• Minimum bend radius: 28mm

This assembly uses 26AWG conductors, PVC(OFNR) jacket, minimum bend radius 28mm. 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 4m (13ft) length gives 40G-QSFP-4SFP-C-0401 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.

40G-QSFP-4SFP-C-0401 occupies the middle of this family between 40G-QSFP-4SFP-C-0301 at 3m (10ft) and 40G-QSFP-4SFP-C-0501 at 5m (16ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 1m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

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.

Our compatibility setup for Brocade 40G-QSFP-4SFP-C-0401 is checked together with the physical 4m (13ft) assembly. Factory verification covers connector condition, host identification, error-free link establishment and electrical continuity, link stability and diagnostic readouts. Providing the exact host model and firmware release helps us identify platform-specific requirements before production.

Use part number 40G-QSFP-4SFP-C-0401 for the 4m (13ft) 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, 40G-QSFP-4SFP-C-0401 and the 4m (13ft) length for easier inventory control.

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
