ES0D0G48VA00 FAQ

Q1: Is it compatible with Huawei S6730 switches? Will there be a bandwidth bottleneck when all 48 ports are simultaneously operating at full load for 10 Gigabit transmission?

A1: Fully compatible! Supports the entire S5700/S6700 series, with backplane bandwidth ≥480Gbps. Full load 10 Gigabit transmission has no bottleneck, meeting the centralized 10 Gigabit access needs of medium-sized networks.

Q2: How is the transmission stability over 20km when deployed with single-mode fiber in a campus backbone network? How much of a price advantage does it have compared to high-end 10 Gigabit models?

A2: Signal attenuation <0.4dB within 20km, no packet loss, no latency fluctuations; the price is 40% lower than high-end 10 Gigabit models and only 15% higher than gigabit upgrade models with the same number of ports, demonstrating a significant cost-performance advantage for 10 Gigabit.

Q3: How to choose between 24/32-port / high-end 10 Gigabit / gigabit upgrade line boards?

A3: 24 ports are suitable for less than 30 10 Gigabit devices, and 32 ports are suitable for 30-40 devices. High-end 10 Gigabit models are over budget, and gigabit models have insufficient performance. For more than 40 10 Gigabit devices, a transmission range of ≤30km, and a mid-range budget, this product offers the best price-performance ratio.
