"The network is looking towards DC (Data Centre) centric, which a boost need for increased bandwidth huawei transport network. Businesses are currently undergoing a digital transformation and consumers require always-on connectivity.

"Huawei supports its customers through innovation; together we build simplified networks ensuring the most effective user experience towards owners. This trial is testimony of Huawei's engagement to innovation."

Geert Standaert, Chief Technology Officer at Proximus, said: "At Proximus we pledge in order to meet the evolving customers demand by investing in technologies to offer them the most beneficial quality and service.

A single super-channel OTN Card which has a transmission speed of 1Tbps was adopted on Proximus’ optical backbone. The trial demonstrated that Proximus' future optical backbone (that has a capacity of 200Gbps channels) can evolve to 400Gbps channels and in some cases 1Tbps super channels sometime soon. Huawei says - by reusing the previous optical platform, chassis, and slot - the capability of the core network links might be increased from 16Tbps to 20Tbps.

The test was conducted over the 1,040 kilometer fiber link utilising an advanced ‘Flexgrid’ infrastructure with Huawei’s Optical Switch Node OSN 9800 platform Huawei GPFD. This approach increases the ability on a fiber cable by compressing the gaps between transmission channels. Such a technique also enhances the density in the transmission channels on fiber, rendering it around 150% better than today’s typical 100Gbps core network links.
