ZTE unveiled a 400G/1T DWDM multi-application network device prototype at the 16th WDM & Next Generation Optical Networking Forum in Monaco. The 400G/1T DWDM prototype uses a multi-subcarrier Orthogonal frequency division multiplexing technology for ultra-long-haul applications. It also is a 16 quadrature amplitude modulation solution for metro and local applications. ZTE said it is also supporting a Nyquist WDM solution for long-haul applications.
ZTE’s 100G DWDM/ optical transport network (OTN) system supports C-band 80-wavelength applications, standard PM-QPSK code pattern adjustment and coherent detection. ZTE has implemented advanced soft decision forward error correction technology. http://www.zte.com.cn
