Traditionally, telecom networks had rigid silos of infrastructure dedicated for specific services and applications. With the advent of network virtualization technologies, network operators can create virtual networks on top of common optical infrastructure through software defined networks (SDN) and network function virtualization (NFV). This brings more dynamism, agility, programmability, and cost-efficiency to network management. Optical transport networks have evolved to support network virtualization seamlessly. Their strength lies in carrying huge volumes of data without limiting network virtualization capabilities.

Network virtualization empowers operators to be more responsive to evolving business requirements. They can launch new services at faster pace, split physical networks for dedicated private line use, and customize bandwidth dynamically. Virtual networks also facilitate rapid service provisioning during network outages or surge demands. Telecom operators are able to extract more value from existing optical assets through virtualization. It allows them to be future-ready for emerging technologies which may require sophisticated virtual networks rather than dedicated infrastructure. This improves long term prospects of optical networks as virtualization becomes increasingly important part of network management. The flexibility and programmability brought by virtualization further consolidates preference for optical transport networks. For instance, according to the U.S.-China Economic and Security Review Commission, the government spending on smart city initiatives in China reached USD 38.92 billion in 2023. Such advancements in smart cities are expected to drive the demand for optical transfer network solutions.
