ES1D2G48SX5S 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, and low insertion loss design ensures stability over long distances.

Q2: How is the signal stability when paired with the ZX module for 100km long-distance transmission? Is it compatible with third-party SFP+ modules?

A2: Signal attenuation <1dB within 100km, no packet loss; Huawei original modules are preferred, but it is also compatible with IEEE standard third-party SFP+ modules, offering flexible adaptation.

Q3: How to choose between 24/32-port/standard SFP high-end line boards?

A3: 24 ports are suitable for less than 30 devices, 32 ports are suitable for 30-40 devices, and the compatibility of the standard SFP model is limited; for more than 40 devices and long-distance requirements, this product offers the best cost performance.
