ES1D2X32SX2S FAQ
Q1: Is this line board compatible with Huawei S9306 switches? Will there be a bandwidth bottleneck when all 32 ports are running at full load simultaneously?
A1: Fully compatible! Supports the entire S9300 series of switches, with a backplane bandwidth ≥320Gbps. There is no bottleneck when all 32 ports are running at full load (total bandwidth 320Gbps), fully meeting the needs of medium-scale high-density access.
Q2: How is the signal stability within a 300m transmission distance when paired with a 10GE SR module? Is it compatible with third-party compliant optical modules?
A2: Extremely stable! Signal attenuation <0.2dB within 300m, with no packet loss or delay. Huawei original optical modules are preferred, but it is also compatible with IEEE-compliant third-party optical modules, offering flexible adaptation and controllable cost.
Q3: What are the core differences between this and Huawei's 24/40-port mid-range 10 Gigabit optical port line board? How to choose?
A3: The core difference lies in port precision: the ES1D2X32SX2S (32 ports) is suitable for medium-sized scenarios with 25-35 devices; the 24-port version is suitable for <25 devices, and the 40-port version is suitable for >35 devices. For devices with 25-35 devices, choose the 32-port version for the highest port utilization and optimal cost.
