Huawei's OptiX OSN 9800 is a next-generation of high-capacity, intelligent, converged optical and packet OTN platform for 100G and beyond 100G. Based on the industry-leading T-bit universal switching chip, the platform supports OTN/VC/PKT. Unlike core-layer DWDM systems like the OSN 8800, the OSN 1800 focuses on service convergence—not raw capacity—but does so. WDM, or wavelength-division multiplexing, is a core backbone technology that delivers bandwidth at high speeds with huge capacity and long-reach coverage. These inherent characteristics now make WDM the technology of choice for metro and access areas as well. They enable multiple high-bandwidth services (from 2 Mbit/s to 100 Gbit/s) to be delivered at less cost.
