目前长途通信光缆上广泛使用的是低于10Gb it/s速率的传输系统,但是随着40Gb it/s技术的快速进步,使得高速率的传输系统终于能够走出实验室并投入商用。光设备制造商很快就将能提供商用化的40Gb it/s光网络解决方案,这种方案有助于降低运营成本,并能满足现在和未来的带宽和业务需求。
At present, the transmission system below 10Gb it / s is widely used in long-distance communication optical cables. However, with the rapid progress of 40Gb it / s technology, the high-speed transmission system finally can be out of the laboratory and put into commercial use. Optical equipment manufacturers will soon be able to offer commercial 40Gb it / s optical networking solutions that will help reduce operational costs and meet current and future bandwidth and business needs.
