LSS7L12QX6E0 FAQ
Q1: Is this circuit board compatible with Huawei S9708 switches? Will there be a bandwidth bottleneck when all 12 ports are running at full load simultaneously?
A1: Fully compatible! Supports the entire S9700 series of switches, with a backplane bandwidth ≥120Gbps. All 12 ports can operate at full load (10GE) simultaneously (total bandwidth 120Gbps) without bottlenecks, fully meeting high-density access requirements.
Q2: How stable is the transmission distance within 55m when using Cat.5e copper cable to connect to monitoring equipment?
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 various devices such as monitoring equipment and terminals.
Q3: What are the key differences between this circuit board and Huawei's 6-port high-end 10 Gigabit Ethernet circuit board (LSS7C06HX6E0)? How to choose?
A3: The core difference lies in port density and slot utilization: The LSS7L12QX6E0 (12 ports, high density) is suitable for high-end scenarios with concentrated equipment and limited slots; the 6-port model is suitable for medium to low density needs. Choose the 12-port high-density model if the number of equipment is greater than 8, otherwise choose the 6-port model.
