According to our service provider, webscale, and network operator customers, Optical networks are critical to increasing network scale while lowering total cost of operations (TCO). Quite simply, they provide the foundation for all services that define our daily lives, with the robust redundancy and resilience necessary to enable always-on services. Nokia optical networks have been helping service providers to easily scale capacity and support a wide range of existing and emerging protocols, while delivering guaranteed service level performance and security over a shared network infrastructure. In many cases, they have relied on OTN technology to deliver TDM and packet services over a shared, common infrastructure while maintaining traffic separation between different users. Preparing the network for today’s and future services to come. There are many stories of how Optical networks are helping to better scale capacity and deliver new services with a better customer experience. Delivering higher performance in more cost-effective and sustainable ways. We would like to tell each story from the perspective of our service provider customers.
