ES1D2G24SED0 FAQ

Q1: Is it compatible with Huawei S9708 switches? Will there be bandwidth bottlenecks or signal attenuation when 24 ports are simultaneously operating at full load for long-distance 10 Gigabit transmission?

A1: Fully compatible! Supports the entire S9300/S9700 series, with backplane bandwidth ≥240Gbps. With SFP + long-distance modules, signal attenuation is <0.8dB within 80km, ensuring no bottlenecks during full-load transmission and meeting high-end long-distance requirements.

Q2: How stable is the 70km transmission when deployed with single-mode fiber in a cross-city backbone network? What are its advantages compared to ordinary 10 Gigabit long-distance models?

A2: No packet loss or latency fluctuations within 70km, supporting repeater-free transmission; ordinary 10 Gigabit models only support ≤40km. This product increases the transmission distance by 100%, eliminating the need for additional repeater equipment and reducing deployment and maintenance costs.

Q3: How to choose between 16/32-port / ordinary 10 Gigabit high-end / mid-range 10 Gigabit line boards?

A3: 16 ports are suitable for <15 10 Gigabit devices, 32 ports are redundant. The standard high-end model only supports ≤40km, and the mid-range model has insufficient long-distance performance. For 15-30 10 Gigabit devices + 40km-80km transmission + high-end reliability requirements, this product is the best choice.
