Brocade 40G-QSFP-4SFP-C-0101 Compatible 40G QSFP+ to 4 x 10G SFP+ Passive Copper Breakout Cable, 1m (3ft)

For short, high-density connections, this DAC cable combines 40G performance with a fixed 1m (3ft) cable run. It corresponds to Brocade 40G-QSFP-4SFP-C-0101 and uses a factory-terminated passive copper link without separate optical modules or patch cords.

Product Highlights

• Compatible alternative to Brocade 40G-QSFP-4SFP-C-0101
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to 4 SFP+
• Fixed length and part number: 1m (3ft), 40G-QSFP-4SFP-C-0101
• Conductor specification: 30AWG
• Minimum bend radius: 21mm

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 21mm. 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.

40G-QSFP-4SFP-C-0101 occupies the middle of this family between 40G-QSFP-4SFP-C-0105 at 0.5m (2ft) and 40G-QSFP-4SFP-C-0201 at 2m (7ft). It adds 0.5m 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.

At 1m (3ft), 40G-QSFP-4SFP-C-0101 is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

Each 40G-QSFP-4SFP-C-0101 compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Brocade platform should be included with the order.

Quote HT part number 40G-QSFP-4SFP-C-0101 with the required quantity. The 1m (3ft) 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.

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.
