Rising demand of high-speed data transmission

With the growth of internet and digital connectivity, the demand for high-speed data transmission has increased exponentially over the years. Various new technologies, such as 5G rollout, internet of things (IoT), machine learning/artificial intelligence, autonomous vehicles, etc., are further driving this demand. High speed data transmission is critical for seamless experience in technologies such as video calling, virtual/augmented reality, streaming high resolution content, and cloud computing. Traditional networks are unable to support such high bandwidth requirements.

Optical transport networks with their ability to carry huge volumes of data at extremely high speeds through fiber optics have become essential infrastructure to support this high-speed digital revolution. They allow internet service providers and telecom operators to scale up their network capacity according to demand surges. Even a slight upgrade in speed from traditional copper networks to optical fiber can improve user experience multifold for technologies dependent on high-speed connectivity. Various industries have realized the benefits of digitization but lack of high-speed network was a bottleneck. Optical networks help overcome this and accelerate digital transformation. Their advantages over traditional networks have made them preferred medium of network expansion globally to support the insatiable demand for data and connectivity. For instance, DataReportal reveals that global internet users reached 4.95 billion at the beginning of 2022, with internet penetration now at 62.5 percent of the world's total population. Additionally, approximately 1.134 Trillion MB of data is created each day. These statistics indicate the escalating usage of data worldwide, necessitating fast and reliable data networks like OTN.

Rise of network virtualization and flexibility

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.
