Optical Transport for Mobile Services
Ways to learn:
Instructor-led | Self-study materials | Learning labs
Course overview
This course is designed for network engineers, IT personnel, and network planning personnel who need to learn the principles and best practices for optical transport of traffic from current and future (5G) cellular networks, from the base stations to the mobile core network. After introducing cellular networks and discussing the challenges of the Radio Access Network (RAN), the course presents the typical use cases for optical fronthaul, midhaul and backhaul. Optical technologies and architectures based on the 1830 Versatile WDM Module (VWM) are proposed for fronthaul to meet 5G requirements, and the Time-sensitive Packet Switch (TPS) is introduced as well. The course includes multiple hands-on lab exercises where students can practice fronthaul configuration as well as troubleshooting in both Coarse Wavelength Division Multiplexing (CWDM) and Dense Wavelength Division Multiplexing (DWDM) scenarios.
