ES1D2X16SSC2 FAQ
Q1: Is this line board compatible with Huawei S9303 switches? Will there be a bandwidth bottleneck when all 16 ports are running at full load simultaneously?
A1: Fully compatible! Supports the entire S9300 series of switches, with a backplane bandwidth ≥16Gbps. There is no bottleneck when all 16 ports are running at full gigabit speeds simultaneously (total bandwidth 16Gbps), fully meeting the needs of small to medium-sized access systems.
Q2: How is the signal stability within a 550m transmission distance when paired with a 1000M SX module? Is it compatible with third-party compliant optical modules?
A2: Extremely stable! Signal attenuation <0.25dB within 550m, with no packet loss or delay. Huawei original optical modules are highly recommended, but it is also compatible with IEEE-compliant third-party optical modules, offering flexible compatibility.
Q3: What are the core differences between this and Huawei's 24/32-port gigabit optical mid-range line board? How to choose?
A3: The core differences lie in port flexibility and cost: The ES1D2X16SSC2 (16 ports) is suitable for small to medium-sized scenarios with 8-20 devices; the 24-port version is suitable for 20-30 devices, and the 32-port version is suitable for more than 30 devices. For devices ≤20, choose the 16-port version for the best cost-performance ratio and no port waste.
