    The optical transmission system based on all-band is considered to be one of the methods to effectively improve the transmission capacity of optical communication. In addition of the C and L bands, the using of other bands for transmission can fully tap the transmission potential of the existing optical fiber network and solve the bottleneck problem of large capacity communication network. The realization of its key technologies and systems is conducive to promoting the industrialization process of related technologies, which has broad economic benefits. This paper analyzes and discusses the current research status of multi-band optical transmission technology. And then as the focus, the performance difference of S、C and L band is studied by experiments. Based on the devices designed for C and L bands, the experiment of 40 km transmission system covering on S、C and L band is completed by using Polarization Division Multiplexed 16 Quadrature Amplitude Modulation (PDM-16QAM) modulation format, and the transmission capacity can reach 122.4 Tbit/s. The multi-band transmission capability of G. 652.D optical fiber is verified, which provicles an experimental basis for further research on multi-band optical transmission technology.
