LST7L12QX6E0 FAQ
Q1: What are the core advantages of the Huawei LST7L12QX6E0? What value does 400G bandwidth bring?
A1: The core advantages are ultra-high bandwidth, dual-rate compatibility, low power consumption, and high reliability. 400G bandwidth reduces the number of links, simplifies network architecture, improves data transmission efficiency, and is suitable for petabyte-level data exchange scenarios.
Q2: Which optical modules does this service board support? Is it compatible with existing 100G equipment?
A2: It supports Huawei standard QSFP-DD 400G optical modules (SR4/LR4/ER4) and QSFP28 100G optical modules; 400G/100G dual-rate adaptive, it is directly compatible with existing 100G equipment without additional configuration.
Q3: How does its energy consumption compare to other 400G service boards of the same level?
A3: Total power consumption ≤360W, single-port power consumption only 30W, 28% more energy-efficient than comparable products, significantly reducing data center energy consumption and heat dissipation pressure, meeting green data center construction requirements.
Q4: Suitable for scenarios with high speed and reliability requirements? Is installation complex?
A4: Suitable for large data center cores, supercomputing centers, carrier backbones, financial core transaction scenarios, etc.; supports hot-swapping, installation without downtime, automatic recognition after insertion into the switch, simple configuration.
