24 March 2020, Shenzhen, China - ZTE Corporation (0763.HK / 000063.SZ), a major international provider of telecommunications, enterprise and consumer technology solutions for the Mobile Internet, today shared its latest research paper on optical networking (ON): Four-Dimensional 8-bit Modulation with KP4 Non-binary FEC for Short-Reach Coherent Optical Transmissions at the Optical Networking and Communication Conference & Exhibition (OFC) 2020. This is the fifth consecutive year that ZTE’s ON research paper has been selected by the OFC.  

According to the research paper, ZTE uses four-dimensional modulation format C4-256 together with RS (544,514) to improve the back-to-back OSNR (Optical Signal to Noise Ratio) tolerance by experiment. Compared with PM-16QAM, the four-dimensional modulation format C4-256 reduces the back-to-back OSNR (Optical Signal to Noise Ratio) tolerance by 0.7dB, and effectively lengthens the transmission distance and improves the network performance without lowering the spectral efficiency. 

With the same spectral efficiency as PM-16QAM, the four-dimensional modulation format C4-256 has higher minimum Euclidean distance due to high-dimensional optimization, so it has stronger tolerance for channel noise. With non-binary FEC (Forward Error Correction), it can keep this advantage to bit-level signals in signal decision and finally get better BER (Bit Error Rate) performance to help improve transmission distance. 

The OFC is the largest global conference and exhibition for optical communications and networking professionals. The program is comprehensive -- from research to marketplace, from components to systems and networks and from technical sessions to the exhibition. The OFC annually invites the authors of groundbreaking cutting-edge papers for communication, so as to specify the direction of optical communication technology development.
