ES1D2L02QFC0 FAQ
Q1: Is this line board compatible with Huawei S9708 switches? Can the transmission distance and speed be guaranteed when paired with a 100GE LR4 module?
A1: Fully compatible! Supports the entire S9700 series of switches. Paired with a 100GE LR4 module, it can stably transmit over 10km, maintaining a single-port rate of 100Gbps. Signal attenuation is minimal, with no packet loss or latency fluctuations, meeting the needs of long-distance interconnection across data centers.
Q2: Will the bandwidth of the mid-range switch's backplane limit when two 100GE optical ports are operating at full load simultaneously?
A2: No limitation! The line board's backplane bandwidth is ≥200Gbps, supporting simultaneous full-load 100GE transmission on two ports, with a total bandwidth of 200Gbps. This fully matches the core performance of mid-range switches, with no bandwidth bottlenecks.
Q3: What are the key differences between this and the Huawei 40GE optical port mid-range line board (ES1D2H02QX2S)? How to choose?
A3: The core differences lie in speed and application scenarios: The ES1D2L02QFC0 (100GE, ultra-high speed) is suitable for mid-range core scenarios requiring ultra-high speed transmission; the 40GE model is suitable for ordinary high-bandwidth scenarios. Choose the 100GE model for core backbone and ultra-high-speed equipment access, and the 40GE model for ordinary high-bandwidth access.
