Real-Time Demonstration of an Integrated Metro-Access Network Carrying Live VR Traffic Based on Multi-Carrier Modulation and Simplified Sub-Band Coherent Detection

We present an integrated metro-access networking scheme based on Alamouti-coded multi-carrier modulation and simplified sub-band coherent detection, and experimentally demonstrated it with real-time DSP in a 300-km communication link carrying live VR traffic, showing error-free performance with a low end-to-end latency of 1.5 ms.
