Huawei Unveils 5th-Gen Optical Network Architecture

摘要

Huawei, a leading global information and communications technology (ICT) solutions provider, unveiled fifth-generation optical network architecture - SDN-based Flex Optical Network (SDN is short for software-defined networking) - at Next Generation Optical Networking Forum, the most important optical conference in Europe. This new architecture paves a new direction in the evolution of optical transport technology. Optical infrastructure is fundamental to telecommunications. Within less than half a century, the optical transport industry has migrated from PDH, through SDH, WDM, to OTN-based coherent 100G WDM, boosting network speeds from megabit-level to terabit-level performance and progressing from pure manual network configuration and management to modest levels of automation.
