SFP+STACK-CU0M5, Huawei SFP+ Stacking Cable, high-speed/0.5m

The Huawei SFP+STACK-CU0M5 is a high-speed stacking accessory cable designed for enterprise and service provider switches that use SFP+ stacking ports. This passive direct attach cable provides reliable short-distance connectivity for building resilient stack systems in wiring closets, campus networks, and small data centers. With SFP+ connectors on both ends and a compact 0.5 m (1.64 ft.) length, the SFP+STACK-CU0M5 helps reduce latency and simplifies cable routing between adjacent devices in the same rack. It is an ideal choice for distributors looking for stable inventory items, for small and medium integrators who need predictable stack links during deployment, and for end users who want a simple, plug-and-play way to expand their Huawei switching capacity across Asia, Europe, Africa, and North America.

The Huawei SFP+STACK-CU0M5 (part number 02311VGK) is a passive electrical cable, so it does not require additional power or configuration, which lowers operating costs and improves long-term reliability. The 25 mm (0.98 in.) minimum bend radius supports neat cable management in dense racks, helping maintain signal integrity while meeting standard installation practices. As a dedicated stack cable rather than a general SFP+ DAC, it is tuned for stable device-to-device stacking, supporting features such as unified management, link redundancy, and seamless failover within a switch stack. This allows network teams to increase port count and performance while managing the stack as a single logical device.

In enterprise campus cores and aggregation layers, the SFP+STACK-CU0M5 is well suited for connecting core or distribution switches positioned side by side, giving consistent high-speed links without the complexity of optical modules. For regional distributors, the compact 0.5 m cable is easy to stock and ship, and works as an add-on sale with Huawei switches that require SFP+ stack interconnects. For global projects that span different regions, using the same Huawei stacking cable model helps keep configurations uniform and simplifies maintenance and spare planning. Whether you are upgrading an existing Huawei stack or building a new stack cluster, the SFP+STACK-CU0M5 offers a straightforward, cost-effective option with predictable performance and installation behavior.
