Real-Time Demonstration of $\mathbf{20}\times \mathbf{25}\mathbf{Gb}/\mathbf{s}$ WDM-PON for 5G Fronthual with Embedded OAM and Type-B Protection

We demonstrate a real-time $20\times 25Gb/s$ WDM-PON system for 5G fronthaul. 25-Gb/s eCPRI services are transparently carried by the WDM-PON system with embedded OAM function and fast type-B protection, satisfying 5G fronthaul requirements including latency and jitter.
