ES1D2G48TED0 FAQ

Q1: Is it compatible with Huawei S9708 switches? Will there be bandwidth bottlenecks or signal attenuation when 48 ports are simultaneously under full load and over a 150m long distance?

A1: Fully compatible! Supports the entire S9300/S9700 series, with backplane bandwidth ≥48Gbps. With Cat.7 copper cable, signal attenuation is <0.3dB within 150m, ensuring no bottlenecks under full load and meeting the needs of large-scale long-distance copper cable access.

Q2: How is the transmission stability at 120m when using Cat.6a copper cable for cross-building deployment? What is the cost advantage compared to optical port solutions?

A2: Signal attenuation is <0.28dB within 120m, with no packet loss and no latency fluctuations. Deployment costs are 50% lower than optical port solutions, eliminating the need for additional optical modules, reusing existing copper cable resources, and making maintenance more convenient.

Q3: How to choose between 24/32-port / standard short-distance / optical port high-end circuit boards?

A3: The 24-port version is suitable for <30 devices, and the 32-port version is suitable for 30-40 devices. The standard short-distance version only supports ≤100m, and the optical version is expensive. For more than 40 devices + 100m-150m long-distance + copper cable deployment, this product offers the best compatibility and cost performance.
