Long-haul core networks: Future needs for cable density and high fiber count cables Lidia Galdino, Corning
Versatile Optical Network Planning
André Richter, VPIphotonics Planning today’s and future optical networks requires versatile, powerful, and flexible network planning tools, which capture network
Over the last five years, long-haul core network traffic has seen a compound annual growth rate of 30%. This unabated network traffic growth is accommodated by both high-capacity fiber services (enabled by innovations in coherent transponder technology) and new
infrastructure and equipment information, support and automatize design tasks, and compare and archive found solutions. They should support a vendor- and technology-agnostic approach to equipment modeling and performance assessment, which permits fast and efficient configuration of scalable networks, accounts for traffic demands, and optimizes spectrum utilization and equipment cost. We present the general concept of such a tool and highlight its operation by addressing several planning scenarios. We discuss a multi-band, multi-span DWDM network accounting for impairments such as ISRS and showcase metro network topologies. In addition, we present a planning approach for incorporating optical satellite networks into existing terrestrial network designs and show how interoperability with numerical system simulations can further enhance the capabilities of such a tool.
fiber deployments. We now have evidence that per-fiber capacity is approaching the Shannon limit – the maximum rate at which data can be reliably transmitted – leaving little room for further capacity improvements. Under this scenario, optical fiber has a prominent role in maintaining the core network capacity growth rate. Given this challenge, we evaluated the future needs for long-haul cable density and high fiber count cables.
Optical fibre fronthaul for the disaggregated 6G RAN Nathan Gomes, UCL
Radio access network (RAN) disaggregation is viewed as essential for meeting the bit-rate, spectral efficiency, user density and energy efficiency demands of future mobile networks. However, demands are then placed on the latency and bit-rate requirements of the fronthaul links

which connect the disaggregated remote radio units to the more centralised functional units (usually termed distributed and central units). Optical fibre communications can meet such demands, but with the links becoming increasingly widespread as future mobile systems are deployed, the use of low-cost technology will be essential. Further, as 6th generation (6G) mobile networks target energy efficiency improvements of two orders of magnitude, the energy consumption of the fronthaul will become a key consideration. A fronthaul transmission system which can respond to demand, reducing its line rate and its energy consumption when the mobile traffic is lower, can play an important role in overall energy efficiency strategies.
This presentation delves into the intricacies of developing low-complexity neural network-based equalizers tailored for optical communications. It explores innovative strategies to overcome challenges encountered in the realms of training, inference, and hardware synthesis.

Fixed access evolution towards 6G networks
Fiber and wireless optic communications have played significant roles in increasing the data capacity of modern transmission systems. Laser and channel nonlinear distortions in optical fiber systems and the inter-symbol-interference and the time-varying channel impulse response
Maxim Kuschnerov, Huawei Technologies The arrival of 6G wireless will transform fixed access networks and its architecture similarly to 5G. We will analyze the implications of 6G on optical fiber access and discuss the joint evolution of wireless, residential and private line access as well the changing drivers for the bandwidth
in optical wireless communication systems have deteriorated the detection and the demodulation of transmitted symbols from the received signals in corresponding systems. In this talk, we will discuss the performance of advanced signal processing in mitigating the laser phase noise and the fiber nonlinearities under dispersion-unmanaged and dispersion-managed long-haul optical link conditions. We will also present signal detection schemes in ultra-violet optical wireless communication systems by designing optimal linear and high- dimensional combinations of extracted, signal-related geometrical features.
