LSS7C02BX6E0 FAQ
Q1: Is this circuit board compatible with Huawei S9708 switches? What are the transmission speed and stability when using Cat.6a copper cable?
A1: Fully compatible! Supports the entire S9700 series of switches. Cat.6a copper cable can achieve stable transmission at 100m, with a single-port rate of up to 10Gbps. The transmission process is resistant to electromagnetic interference, with no packet loss or latency fluctuations, meeting the requirements of high-end networks.
Q2: Will the two 10G Ethernet ports be limited by the backplane bandwidth of the high-end switch when operating at full load simultaneously?
A2: No limitation! The circuit board is designed specifically for high-end switches, with ample backplane bandwidth. It supports simultaneous 10GE full-load transmission on two ports, with a total bandwidth of up to 20Gbps, fully matching the performance of high-end switches without bottlenecks.
Q3: What are the core differences between this circuit board and Huawei's high-end 10G fiber optic circuit boards (such as LSS7C06HX6S0)? How to choose?
A3: The core difference lies in the transmission medium and scenario: The LSS7C02BX6E0 (electronic port + copper cable, ≤100m) is suitable for short-distance interconnection and stacking scenarios in high-end data centers; the optical port version (optical module + fiber, 300m-10km) is suitable for long-distance interconnection. For high-end short-distance connections, choose the electrical port version; for long-distance connections, choose the optical port version.
