Huawei, a leading global information and communications technology (ICT) solutions provider, and Telefonica Chile will deploy the world's first commercial OTN-based 400G wavelength-division multiplexing (WDM) network this year using cutting-edge 100G and 400G technologies.
 
This will be the industry's fastest metropolitan WDM network based on 400G OTN technology, which is available only from Huawei at present.
 
Telefonica Chile commenced LTE and IPTV rollouts in Chile in 2013, which are expected to experience huge bandwidth pressure over the coming years. To address this pressure, Telefonica Chile plans to deploy the metro WDM network in Chile's capital city Santiago, which represents nearly 40% of the nation's population and 45% of its GDP. Santiago has the largest bandwidth consumption of any city in Chile.
 
The project will adopt Huawei's mature coherent 100G technology, and also PDM-16QAM-based coherent 400G technology to deliver maximum bandwidth for data centers in Santiago. OTN-based multiplexing, cross-connection, and grooming of multi-granular traffic will be introduced into the super-fast system to optimize transmission flexibility and efficiency.
 
"Addressing bandwidth challenges for customers is our strategic focus," said Jack Wang, president of Huawei's transport network product line. "Huawei will continue investing in beyond-100G technology and building information networks as wide as the Pacific Ocean to meet the future needs of the network," added Jack Wang.
 
Huawei has deployed over 150 commercial 100G networks worldwide and made several breakthroughs in the beyond-100G field. In June 2012, Huawei and KPN International completed the world's first 400G field trial.
 
In December 2012, Huawei conducted the world's first 2T field trial with Vodafone, achieving 2 Tbit/s transmission over a distance of up to 3,325 km. In March 2013, Huawei unveiled a 40T WDM prototype, the highest capacity in the industry, at the OFC/NFOEC event in America.
