LST7X48SX6S1 FAQ
Q1: What are the core advantages of this service board? What practical value does the high density of 48 ports bring?
A1: The core advantages are ultra-high density of 48 ports, 10G/1G dual-rate compatibility, low power consumption, and high stability. High density significantly saves switch slots, reducing the number of devices deployed. The dual-rate design reduces upgrade costs and adapts to ultra-large-scale all-optical networks.
Q2: Which optical modules does it support? Can it directly connect to existing 1G legacy equipment?
A2: It supports Huawei standard SFP+ 10G optical modules (SR/LR/ER) and SFP 1G optical modules; dual-rate adaptive design allows direct connection to existing 1G equipment without additional converter configuration or manual debugging.
Q3: How does its power consumption and forwarding performance compare to other 48-port 10G boards of the same level? A3: Total power consumption ≤180W, 32% more energy efficient than comparable products; forwarding capacity ≥960Gbps, supports full-load concurrent forwarding of 48 ports, no performance bottlenecks, suitable for high-load scenarios.
Q4: What scale of network scenarios is it suitable for? Is installation complex?
A4: Suitable for ultra-large-scale 10G access scenarios such as large data centers, medium-to-large-scale campuses, and carrier city aggregation; supports hot-swapping, installation without downtime, automatic speed recognition after insertion into the switch, simple configuration.
