介绍了基于超密集波分复用（DWDM）技术、信道间隔为12.5 GHz的地面太比特波分复用（WDM）传输系统的应用领域、基本技术和可行性。数值模拟结果定量地表明，超dwdm传输的优点是在几百公里的标准单模光纤（SMF）中不需要色散补偿。为支持超波分复用传输，研制了仅由一个强度调制器和一个相位调制器组成的多波长发生器样机，作为具有高波长稳定性的小尺寸波分复用光源。我们使用该原型进行了1.28 tb /s（512通道/spl次/ 2.5 Gb/s）的传输实验，通道间距为12.5 GHz，超过320 km （80 km /spl次/ 4跨度）的标准SMF，没有色散补偿。通过数值模拟和传输实验，验证了信道间距为12.5 GHz的超dwdm在地面系统中传输的潜力和可行性。
This paper describes application areas, elemental technologies, and the feasibility of terrestrial terabit wavelength division multiplexing (WDM) transmission systems based on super-dense wavelength division multiplexing (DWDM) technologies with a channel spacing of 12.5 GHz. Numerical simulation results quantitatively show that the merit of super-DWDM transmission is the elimination of the need for dispersion compensation over the several hundreds of kilometers of standard single-mode fiber (SMF). To support super-DWDM transmission, the prototype of a multiwavelength generator, which consists of just an intensity modulator and a phase modulator, is developed as a small-size WDM light source with high-wavelength stability. We use this prototype to conduct a 1.28-Tb/s (512 channels /spl times/ 2.5 Gb/s) transmission experiment with a channel spacing of 12.5 GHz over 320 km (80 km /spl times/ 4 span) of standard SMF without dispersion compensation. The potential and the feasibility of super-DWDM transmission with a channel spacing of 12.5 GHz for terrestrial systems is confirmed by the numerical simulation and the transmission experiment.
