LSS7X48SX6E0 FAQ
Q1: Is this circuit board compatible with the Huawei S9712 switch? Will there be a bandwidth bottleneck when all 48 ports are running at full load simultaneously?
A1: Fully compatible! Supports the entire S9700 series of high-end switches, with a backplane bandwidth ≥480Gbps. There is no bottleneck when all 48 ports are simultaneously operating at full load (480Gbps total bandwidth), fully meeting high-density access requirements.
Q2: How stable is the transmission over a 55m distance when using Cat.5e copper cable to connect terminal devices? Is it interference resistant?
A2: Extremely stable! Cat.5e copper cable can stably transmit at 10GE rates within 55m, with electromagnetic interference resistance meeting EMC Class A standards. There is no packet loss or latency fluctuation, making it suitable for servers, terminals, monitoring equipment, and various other devices.
Q3: What are the core differences between this circuit board and the Huawei 48-port 10 Gigabit optical port high-end circuit board (LSS7X48SX6S0)? How to choose?
A3: The core difference lies in the transmission medium and scenario: The LSS7X48SX6E0 (electronic port + copper cable, ≤100m) is suitable for short-distance, high-density scenarios within a data center using multiplexed copper cables; the optical port version (fiber optic, 300m-40km) is suitable for long-distance interconnection. For short-distance interconnection within a data center, choose the electrical port version; for cross-data center/long-distance interconnection, choose the optical port version.
