Recently the remote work/entertainment situation enforced by the outbreak of the COVID-19 pandemic has shown the importance of upgrading the access network to enable needed services.
In this workshop we will discuss the status of optical access, how optical access will look like in the future, and if we are in good shape for the future.
Copper access is being upgraded to optical access because of an increasing demand for more data rate for super-broadband services with minimum latency for fixed networks’ applications for residential and business users that have evolved, like gaming, holograms, AR/VR, Industry 4.0, live sport/music viewing, etc.
In addition to the residential and business use-cases, another use-case that will shape future optical access is mobile backhauling. This use-case requires optical links that are capable of high data rates. Mobile users’ high data rate and applications have evolved, meaning convergence of fixed and mobile services, use of small cells, sensors, IoT, more flexibility, and strict requirements for latency is needed. But what data-rate do we need for 5G, 20 Gb/s per user? Do we need a peak rate over 100 Gb/s by 2030 for 6G?
We will consider energy efficiency, low carbon emission networks, and resilient networks (lifeline, battery, etc..) for future access.
Optical networks are also expected to assist with societal requirements (fire assistance, sensors for agriculture, water level monitoring, climate, etc.) to support the Sustainable Development Goals (SDGs) by the United Nations.
To enable all the emerging use-cases for optical access, a cost-effective symmetrical data rate of 100 Gb/s and beyond will be needed. This also means new optical access standards: what comes after the 25G and 50G-PON standards? Here the topics of discussion are IM/DD versus coherent, introduction of flexibility, and point-to-point versus point-to-multipoint architectures. Will optical access standards move forward for all types of architectures? Will cost-effective coherent access be feasible?
