Abstract

Hybrid 200Gchip/s QAM-based opto-electrical labels with high orthogonality are generated using the convolution of optical 16-level and electrical 4-level PSK codes. The combined simultaneous use of optical and electrical encoding increases system flexibility and code orthogonality, as well as code recognition performance. By performing 50 G-class low-speed LN-PM-based electrical processing on the 200 Gchip/s PSK-based optical code labels generated by a multiport optical encoder, the value of PCR indicating the code orthogonality is increased significantly, and the receiver sensitivity is improved by 0.5dB to achieve LER =10-9 in the next-generation optical packet switching networks.
