ZTE Corporation has revealed that it successfully conducted 400G optical transport tests last month, within T-Mobile Austria’s existing DWDM network. The test included a smooth capacity upgrade of the mobile operator’s 10G/100G DWDM network via the implementation of a 400G link between Vienna and Graz, significantly extending the capacity available for future network evolutions towards new technologies, such as cloud operation and big data concepts. For end-users, ZTE said the upgrade will increase the user experience by raising the speed of data connections and increasing the available capacity.
In a separate announcement, ZTE said it has signed a ‘Pre5G Memorandum of Understanding (MoU)’ with mobile operator Hutchison Drei Austria (Drei) to build the first ‘Pre5G’ trial site in Europe. ZTE’s Pre5G concept involves using core 5G technologies already on 4G networks to effectively alleviate the pressure of the data traffic surge on telecom operators’ networks before the standardisation of 5G technologies comes into place. ZTE’s Pre5G Massive MIMO base station will be commercially available on a large scale in 2016. Xu Huijun, CTO of ZTE, commented: ‘We believe that the application of Pre5G will help Hutchison Drei Austria maintain its performance … and enable it to build a world-class network.’
