Huawei Technologies today said it tested a single super-channel OTN Card with a transmission speed of 1 Tbps on the optical backbone of Proximus, a telecom operator in Belgium.
The aim of the test was to determine whether this technology can be integrated into the core network, to anticipate the constant and growing customers demand for more bandwidth.
This trial shows that the Proximus future optical backbone with a capacity of 200Gbps channels, can efficiently evolve to 400Gbps channels and even 1Tbps super channels in the future by using Huawei technology. By reusing the existing optical platform, chassis and slot, telecom operators can upgrade the transmission capacity of the core network links from 16Tbps to 20Tbps.
“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,” said Geert Standaert, chief technology officer at Proximus.
Proximus conducted the test over a 1,040 kilometer fiber link using a Flexgrid infrastructure with Huawei’s Optical Switch Node OSN 9800 platform to increase the capacity on a fiber cable by compressing the gaps between transmission channels. The technique increases the density of the transmission channels on fiber, making it around 150 percent more efficient than today’s typical 100Gbps core network links.
“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,” said Jeffrey Gao, president of the Huawei transmission network product line.
