ES0D0G48SC00 FAQ

Q1: Is it compatible with Huawei S6730 switches? Will there be bandwidth bottlenecks with 48 ports operating at full load simultaneously and over an 80km long distance?

A1: Fully compatible! Supports the entire S5700/S6700 series, with backplane bandwidth ≥48Gbps. Full load transmission is bottleneck-free, and the low insertion loss design ensures stability within 80km, meeting the needs of medium-sized long-distance access.

Q2: How is the signal stability when paired with ZX modules for 80km long-distance transmission? Is it compatible with third-party compliant optical modules?

A2: Signal attenuation <0.8dB within 80km, with no packet loss. Huawei original modules are preferred, but it is also compatible with IEEE standard third-party modules, offering flexible adaptation and controllable costs.

Q3: How to choose between 24/32-port / mid-range high-performance line boards?

A3: The 24-port version is suitable for <30 devices, and the 32-port version is suitable for 30-40 devices. The high-performance version only supports ≤60km. For more than 40 devices, long distance of 60km-80km, and mid-range stability requirements, this product has the best compatibility.
