AOC-Q28DD-2Q28-100G-7MDell AOC-Q28DD-2Q28-100G-7M Compatible 200G QSFP-DD 8 x 25G NRZ to 2 x 100G QSFP28 4 x 25G NRZ Active Optical Breakout Cable, 7m (23ft)
For densely populated equipment, the fixed 7m (23ft) version of Dell AOC-Q28DD-2Q28-100G-7M offers a clearly defined 200G link without separate optical modules or patch cords. The AOC assembly uses QSFP-DD to 2x 100G QSFP28; its power, mechanical and diagnostic details are listed where supplied so port density and cable management can be assessed together.

Signal and Lane Configuration
The listed modulation format is NRZ. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.
Power and Thermal Planning
The rated power consumption is 4W (QSFP-DD End) 2.5W (QSFP28 Per End). Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.
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.
Network and Protocol Considerations
The intended application is determined by the host interface and protocol support. Listed interface and protocol references include QSFP-DD MSA V5.0, QSFP28 MSA, CMIS V4.0, SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.
Breakout Port Mapping
The QSFP-DD to 2x 100G QSFP28 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.
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
Measure twice before deploying this 7m (23ft) cable: once along the planned route and again after accounting for service access. The objective is adequate reach without a concealed surplus. Support the integrated optical cable and both optical engines, preserve front-panel clearance and check that nearby power cords or sharp hardware cannot damage the jacket. Within this family, AOC-Q28DD-2Q28-100G-5M is shorter at 5m (16ft), while AOC-Q28DD-2Q28-100G-10M is the next longer choice at 10m (33ft); comparing those two boundaries helps avoid both tension and unnecessary slack.
Position Within the Length Range
AOC-Q28DD-2Q28-100G-7M occupies the middle of this family between AOC-Q28DD-2Q28-100G-5M at 5m (16ft) and AOC-Q28DD-2Q28-100G-10M at 10m (33ft). It adds 2m over the shorter option for extra routing clearance, while the next longer version adds another 3m. 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 stated power consumption is 4W (QSFP-DD End) 2.5W (QSFP28 Per End); the jacket material is OFNP.
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 AOC-Q28DD-2Q28-100G-7M.
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. Where supported by the host, receive activity and diagnostic indications are reviewed together with the established link.
Frequently Asked Questions
Is this an original Dell cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies Dell AOC-Q28DD-2Q28-100G-7M.
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.
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.
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. Worldwide courier services are available, with air or sea freight for consolidated shipments; freight-collect delivery and coordination with a customer’s logistics provider can be arranged.
