40G-QSFP-4SFP-C-0701Brocade 40G-QSFP-4SFP-C-0701 Compatible 40G QSFP+ to 4 x 10G SFP+ Passive Copper Breakout Cable, 7m (23ft)
For densely populated equipment, the fixed 7m (23ft) version of Brocade 40G-QSFP-4SFP-C-0701 offers a clearly defined 40G link without separate optical modules or patch cords. The DAC assembly uses QSFP+ to 4 SFP+; its power, mechanical and diagnostic details are listed where supplied so port density and cable management can be assessed together.

Cable Construction and Routing
This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 30mm. 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.
Position Within the Length Range
40G-QSFP-4SFP-C-0701 is the longest of 7 verified length options in this family. Compared with 40G-QSFP-4SFP-C-0501 at 5m (16ft), 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.
High-Density Rack Integration
In a densely populated rack, connector access and airflow are part of the link design. Choose the shortest length that follows the managed path comfortably, avoid tight bundles around the connector housings and preserve room for latch operation. Where power consumption is listed, include every populated interface in the host thermal budget rather than assessing a single cable in isolation. For this assembly, the listed conductor specification is 26AWG; the minimum bend radius is 30mm; the jacket material is PVC (OFNR).
Network and Protocol Considerations
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.
Breakout Port Mapping
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.
Passive Copper Operation
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.
Length Selection and Installation Planning
Choose 40G-QSFP-4SFP-C-0701 when the measured managed path justifies 7m (23ft), not simply to leave a large spare coil. Additional reach can simplify adjacent-rack routing, yet unused cable still needs bend-safe storage and ventilation clearance. Keep identification visible so this extended version is not confused with shorter spares. The next shorter verified assembly is 40G-QSFP-4SFP-C-0501 at 5m (16ft), which is the better comparison when the managed route leaves substantial unused cable.
Quality Assurance and Packaging
Each assembly receives a visual connector inspection and functional link check before it is coiled and protected. Packaging is selected to avoid compressing the cable into a tight bundle, and optional rack-based labels help maintain an orderly installation when many identical interfaces are populated together. Volume orders can include customer references on the labels and carton list.
Ordering Information
Provide the exact part number, length, quantity and target interface density. For multi-rack projects, list each length separately and identify any preferred carton grouping. Host model and software information can be included for a compatibility review before production or dispatch. Quantity and any labeling instructions should be attached specifically to 40G-QSFP-4SFP-C-0701.
Brocade Compatibility and Factory Testing
The assembly is evaluated for host recognition and stable link operation, with diagnostics checked where the interface provides them. This approach verifies more than electrical or optical continuity. Exact platform and firmware information remains valuable in high-density deployments because port mode and qualification policy can differ within the same connector family. Both connectors are examined before the operating test, which includes link stability and diagnostic indications.
Frequently Asked Questions
Is this an original Brocade cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies Brocade 40G-QSFP-4SFP-C-0701.
Can excess cable be folded into a compact bundle?
No. Use a supported, bend-safe service loop and observe the listed minimum bend radius. Do not crease the cable or tighten ties around the connector boots.
Will any matching connector operate at the same speed?
Not necessarily. Both hosts must support the stated rate, identification, lane mapping and any required breakout configuration; mechanical compatibility alone is insufficient.
What details assist a compatibility review?
Provide the equipment manufacturer, model, port type, hardware revision and software release, together with the OEM reference, required length and quantity.
Shipping and Lead Time
Available stock is normally prepared for dispatch within one to three working days, while larger production requirements are scheduled with the order. International express, air cargo and sea freight can be selected according to destination and carton volume; customer courier accounts and nominated forwarders are also accepted.
