This course is designed for engineers, IT, and network planning personnel who need to learn the basic principles and practices of optical networking. It introduces network equipment, interworking principles, node functionalities, main transport technologies, and basic concepts related to protection, restoration, control, and management. Additionally, the main concepts of Wavelength Division Multiplexing (WDM) transmission systems (principles, standards, and components) are covered. Within the course, there are three main themes: optical network design, network elements, and the network management system. Participants will become familiarized with the Engineering and Planning Tool (EPT) and they will practice with Switched WDM nodes (including the Photonic Service Switch family – PSS-32 and PSS-24x), and learn how to manage the network through the Network Functions Manager for Transport (NFM-T). Ultimately, this course explains several basic use cases and reinforces this knowledge through practical lab exercises where participants design and build a simple optical network using the 1830 EPT and NFM-T on an 1830 PSS-based network.
