In a joint effort with Proximus, Huawei has successfully completed a joint trial which has resulted in speeds of up to 1Tbps being transferred over an optical signal. Such incredible transmission speeds would allow for approximately 33 high-definition films in a second. 

The innovative Chinese network vendor first partnered with Proximus in January and marks the first time Huawei will have tested its technology with an operator. Trials are being performed to prepare for the growing amount of demand consumers are placing on networks, and ensure bandwidth is available to deal with it. 

“The network is turning to DC (Data Center) centric, which brings a boost demand for increased bandwidth. 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 best user experience towards end users. This trial is testimony of Huawei’s engagement to innovation,” says Jeffrey Gao, President of the Huawei transmission network product line.

We want to let our network infrastructure evolve to support current and future bandwidth demands

A single super-channel OTN Card with a transmission speed of 1Tbps was used on Proximus’ optical backbone. The trial showed that Proximus’ future optical backbone (with a capacity of 200Gbps channels) can evolve to 400Gbps channels and even 1Tbps super channels in the future. Huawei says – by reusing the existing optical platform, chassis, and slot – the capacity of the core network links can be increased from 16Tbps to 20Tbps. 

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

Geert Standaert, Chief Technology Officer at Proximus, said: “At Proximus we pledge to satisfy the evolving customers demand by investing in new technologies to offer them the best quality and service. Together with Huawei we want to let our network infrastructure evolve to support current and future bandwidth demands and offer our customers an outstanding user experience.”
