Huawei and TIM have built the world's first 100G WDM network based on optical fiber G.653

Huawei has announced the successful completion of a joint project with the Brazilian operator TIM to build the world's first coherent 100G WDM network based on optical fiber G.653. This is one of the first 100G WDM networks in Latin America.

Until now, the use of support networks TIM 10G and 40G WDM. As new services and the rapid development of technologies such as FTTx, UMTS and LTE, the load on the core network. Restrictions 10G WDM networks do need to address the network upgrade to 100G. Optical fiber G.653 (dispersion-shifted fiber) used in networks TIM, different fiber G.652. Optical fiber G.653 strongly subject to nonlinear effects such as four-wave mixing (FWM), which makes it incompatible with WDM systems long range.

Huawei said that has extensive experience in building high-speed transport networks and has developed advanced technology to overcome this limitation. These technologies include the use of special methods of modulation suppression algorithms compensate for nonlinearities and PMD. Using these technologies, it effectively eliminates such restrictions fiber G.653, as sensitivity to non-linear effects, and much of the polarization-mode dispersion (PMD). This allows for the transmission of signals 100G long-distance (over 1000 km). Experience from TIM and Huawei in network implementation 100G WDM, will set an example for other operators in Latin America during the construction of networks of 100G WDM.
