Q:What is the Key distinction between Huawei MPLA and MPLB?
A: Functionally, the most significant difference is the enhanced per-slot bandwidth. While the MPLA supports 100 Gbit/s in load-sharing mode, the MPLB delivers 200 Gbit/s. This doubling of bandwidth represents a major performance upgrade, enabling the MPLB to handle higher data throughput for demanding applications.
