SFP+STACK-CU1M5, Huawei SFP+ Stacking Cable, high-speed/1.5m

The Huawei SFP+STACK-CU1M5 is a high-speed stack cable accessory designed for enterprise and carrier-class switches that use SFP+ stacking interfaces. This passive SFP+ high-speed dedicated stack cable, with a length of 1.5 m, is ideal for building resilient stacking backbones in wiring closets, server rooms, and small data centers. With SFP+ connectors on both ends, the SFP+STACK-CU1M5 delivers stable, low-latency interconnection between compatible Huawei switches, helping Asian, European, African, and North American networks simplify deployment and avoid complex optical modules for short-reach stacking. Distributors can count on a standard Huawei part number (02311VGN) for streamlined procurement and inventory control, while system integrators benefit from predictable performance and straightforward installation in rack environments. The 1.5 m cable length provides enough reach to connect devices in the same rack or between adjacent racks, without adding unnecessary cable slack that can block airflow or complicate cable management.

As a passive copper stack cable, the Huawei SFP+STACK-CU1M5 does not require external power or optical transceivers, which helps reduce both cost and potential failure points. The minimum bend radius of 25 mm supports flexible routing through cable managers while protecting the internal conductors from damage during installation and maintenance. For end users, this means more reliable switch stacking performance and fewer unexpected outages caused by poor cabling practices. The SFP+STACK-CU1M5 is well suited for campus aggregation, enterprise core, and branch consolidation projects where multiple switches must operate as a single logical device for simplified management and higher availability.

In real-world deployments, this Huawei stack cable helps keep latency low between stacked units, which is important for converged services such as voice, video, and data. It also supports straightforward upgrades: new switches can be added to an existing stack with minimal downtime, using the same cable type. Whether you are a distributor building regional stock, a small or mid-size integrator planning a new switching stack, or an end customer refreshing an existing Huawei switching platform, the SFP+STACK-CU1M5 offers a stable, standards-based option for short-distance stacking links. Combined with Huawei’s switch software features, using dedicated stack cables such as the SFP+STACK-CU1M5 helps ensure predictable performance, easier troubleshooting, and a cleaner cabling layout across diverse network environments.
