ES1D2G48SX1E FAQ

Q1: Is it compatible with Huawei S9708 switches? Will there be bandwidth bottlenecks with 48 ports operating at full load and long-distance transmission?

A1: Fully compatible! Supports the entire S9300/S9700 series, backplane bandwidth ≥48Gbps, no bottlenecks under full load transmission, low insertion loss design ensures stability within 80km, meeting large-scale access needs;

Q2: How is the signal stability when paired with ZX modules for 80km long-distance transmission? How much of a price advantage does it have compared to the ultra-long-distance version?

A2: Signal attenuation <0.8dB within 80km, no packet loss; price is 25% lower than the 120km ultra-long-distance version, offering the best cost-performance ratio when ultra-long-distance requirements are not needed, compatible with IEEE standard third-party modules;

Q3: How to choose between 24/32-port/ultra-long-distance high-end line boards?

A3: 24 ports are suitable for <30 devices, 32 ports are suitable for 30-40 devices, and the ultra-long-range version is suitable for scenarios >80km; for more than 40 devices + 300m-80km long distance + controllable budget, this product offers the best cost performance.
