CBL-QSFP-4 x 10G-AOC15MDell CBL-QSFP-4 x 10G-AOC15M Compatible 40G QSFP+ to 4 x 10G SFP+ Active Optical Breakout Cable, 15m (49ft)
For densely populated equipment, the fixed 15m (49ft) version of Dell CBL-QSFP-4 x 10G-AOC15M offers a clearly defined 40G link without separate optical modules or patch cords. The AOC 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 OFNP 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.
Integrated Optical Assembly
The optical engines and fiber are permanently integrated into this AOC. There are no detachable optical modules to clean or exchange. Handle the complete assembly by its connector housings and cable, and keep both ends matched to the same interface specification.
Length Selection and Installation Planning
Choose CBL-QSFP-4 x 10G-AOC15M when the measured managed path justifies 15m (49ft), 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. Within this family, CBL-QSFP-4 x 10G-AOC10M is shorter at 10m (33ft), while CBL-QSFP-4 x 10G-AOC20M is the next longer choice at 20m (66ft); comparing those two boundaries helps avoid both tension and unnecessary slack.
Position Within the Length Range
CBL-QSFP-4 x 10G-AOC15M occupies the middle of this family between CBL-QSFP-4 x 10G-AOC10M at 10m (33ft) and CBL-QSFP-4 x 10G-AOC20M at 20m (66ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.
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 minimum bend radius is 30mm; the jacket material is OFNP.
Network and Protocol Considerations
The intended application is determined by the host interface and protocol support. Listed interface and protocol references include 10G/40Gigabit Ethernet or Fibre Channel. 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.
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. Neutral packaging and customer-specific packing documentation are available on request.
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 CBL-QSFP-4 x 10G-AOC15M.
Dell 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 receive activity and diagnostic indications.
Frequently Asked Questions
Is this an original Dell cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies Dell CBL-QSFP-4 x 10G-AOC15M.
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.
How should an unused assembly be stored?
Protect both connector ends, keep the cable in a loose bend-safe coil and retain its part-number label so the length and compatibility identity remain traceable.
Can different brands be connected with the same assembly?
Only where both hosts explicitly support the complete interface and compatibility arrangement. Document each end and select the appropriate brand-specific product when required.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, with production quantities confirmed at order stage. 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.
