Huawei and KPN International completed the world's first test existing European network 400G

, Huawei and telecom operator KPN International reported the successful completion of the world's first field test of a European network 400G. Network-based 400G OTN has a length of 540 km from Amsterdam (Netherlands) to Dusseldorf (Germany), which has a reserve that allows you to add another 300 km after the end station.

In the words of the companies, a significant increase in traffic contributes to a large-scale backbone network technology commercialization of 100G. In the development of high-speed technology professionals are paying more attention to technology outside of the 100G, in particular the 400G.

Tests were conducted 400G transmission technology KPN International, in its European backbone WDM, Huawei built in 2008 using equipment NG-WDM. It was the first network to update Huawei 100G coherent transmission in 2011. Tests were conducted on the channel with the most intense traffic. The tests confirmed the results previously obtained in laboratory conditions: the transfer of this technology is very promising. The next stage - the continuation of testing with the included functional DSP.
