Huawei helps TIM Brazil build G.653-based 100G WDM Network

Feb. 18, 2013
Huawei Technologies Co Ltd. says it had successfully assisted TIM Brazil, a subsidiary of Telecom Italia Group, in constructing what it claims is the world's first coherent 100G WDM network based on dispersion-shifted singlemode G.653 optical fiber. It is also one of the first 100G DWDM networks in Latin America.

Huawei Technologies Co Ltd. says it had successfully assisted TIM Brazil, a subsidiary of Telecom Italia Group, in constructing what it claims is the world's first coherent 100G WDM network based on dispersion-shifted G.653 singlemode fiber. It is also one of the first 100G DWDM networks in Latin America.

TIM's core optical transport networks are currently 10G and 40G WDM. As new services appear and grow rapidly, such as FTTx, UMTS, and LTE, the core network will become increasingly strained. The limitations of a 10G WDM networks make the upgrade to 100G networks particularly urgent.

The G.653 optical fiber used on TIM's current networks has different optical properties from the standard G.652 optical fiber used in most other regions of the world. Featuring strong non-linear effects such as four-wave mixing (FWM) and polarization mode dispersion (PMD), G.653 optical fiber is not usually compatible with long-haul DWDM transmission.

Huawei says it has developed advanced technologies to overcome these constraints, including modulation format technologies, non-linearity suppression algorithms, and PMD compensation algorithms. These technologies effectively address the constraints of the G.653 optical fiber and enable long-haul transmission of 100G signals over distances in excess of 1000 km.

Last year Infinera Corp. (NASDAQ: INFN) and its Japanese partner, Nissho Electronics, used the DTN-X platform to deliver 8 Tbps via superchannels across 800 km of ITU-T G.653 fiber (see “Infinera, Nissho show 8-Tbps transmission over dispersion-shifted fiber”).

Huawei says the experience that TIM and Huawei have obtained in deploying this 100G WDM network will go a long way to inspire confidence for constructing 100G WDM networks across Latin America.
