Improving WDM in SMF-PON with Polarization Multiplexing and Optical Comb

The social media platforms have become more data-intensive with the proliferation of high-resolution images, videos, and live streaming. To meet these growing bandwidth demands, telecommunication companies and internet service providers are continually upgrading their networks, deploying fiber-optic connections, and developing faster and more efficient technologies, 5G for wireless communication. Passive Optical Networks are indeed well considered an attractive and efficient solution for delivering high-speed internet and other communication services to end-users. The combination of cost efficiency, energy efficiency, flexibility, scalability, and other advantages makes PONs an appealing choice for telecommunications providers looking to deliver high-speed broadband and other services to a wide range of customers. They operate particularly well with deployments of FTTH and FTTB, which are next-generation broadband access networks. The paper is a systematic study and analysis approach in optimizing the system for both high data rates and enhanced capacity, considering different modulation techniques such as MDRZ, CSRZ, NRZ, RZ.
