H3C QSFP-4 x 10G-D-AOC-20M Compatible 40G QSFP+ to 4 x 10G SFP+ Active Optical Breakout Cable, 20m (66ft)

The QSFP-4 x 10G-D-AOC-20M cable on this page is the 20m (66ft) version for H3C hosts requiring 40G operation. Its QSFP+ to 4 SFP+ AOC construction reduces the connection to one factory-terminated assembly. Related lengths, brand cross-references and rack-integration notes support a precise high-density deployment.

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.
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.
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
The extended 20m (66ft) configuration gives QSFP-4 x 10G-D-AOC-20M a specific place in the family reach range. It should not be treated as a universal substitute for every shorter order code. Match it to a documented route, protect the integrated optical cable and both optical engines during handling and retain the part-number label for later maintenance. Within this family, QSFP-4 x 10G-D-AOC-15M is shorter at 15m (49ft), while QSFP-4 x 10G-D-AOC-25M is the next longer choice at 25m (82ft); comparing those two boundaries helps avoid both tension and unnecessary slack.
Position Within the Length Range
QSFP-4 x 10G-D-AOC-20M occupies the middle of this family between QSFP-4 x 10G-D-AOC-15M at 15m (49ft) and QSFP-4 x 10G-D-AOC-25M at 25m (82ft). 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.
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 QSFP-4 x 10G-D-AOC-20M.
H3C 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 H3C cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies H3C QSFP-4 x 10G-D-AOC-20M.
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. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.
