LST3L12QX6E0 FAQ
Q1: What are the maximum single-port speed and transmission distance of the Huawei LST3L12QX6E0 interface card? Does it support hot-swapping?
A1: Maximum single-port speed is 40Gbps, and maximum transmission distance is 40km (with a QSFP+ 40G LR4 module); it supports QSFP+ module hot-swapping, ensuring uninterrupted backbone service maintenance.
Q2: Is this interface card compatible with the Huawei S7706 switch? What is the maximum number of cards supported by a single S12712 unit?
A2: Fully compatible with the S7706 switch (requires upgrading to the latest system version); a single S12712 unit supports a maximum of 8 cards, providing 96 40G ports to meet the needs of ultra-large backbone expansion.
Q3: What are the core advantages of the LST3L12QX6E0 compared to 2-port/4-port 40G interface cards?
A3: The port density per slot is increased by 3-6 times, and the slot occupancy is reduced by 60%-80% for the same 40G port requirement; the cost per port is 30% lower, resulting in a significant total cost advantage when deployed on a large scale, and higher backbone expansion efficiency.
