Open Fiber's ZION fiber backbone has passed the test with flying colours 600 Gigabits per second (Gbps). The new result achieved on its national transport backbone for a long-distance optical link adds to the one recorded last year on 400Gbps and even earlier on 200Gbps. It's about the first transmission link on a national backbone network made in Italy at 600 Gbps, on a single optical carrier on an active infrastructure with the highest spectral efficiency (transported bits per unit of bandwidth) ever achieved.
Thanks to this result Open Fiber's fiber optic infrastructure is the most advanced and capable of supporting the development of the new Gigabit digital services Society and 5G, therefore high-resolution 4K/8K video, cloud gaming, augmented and virtual reality, intelligent transport, advanced healthcare, citizen safety, digitization of the PA, e-learning and smart working.
Zion is, in fact, the only national backbone capable of carrying data without regeneration of optical signals, with capacities of 100Gbps over distances up to 2.500 kilometres, 200Gbps up to 1.500 kilometres, 400Gbps up to 900 kilometres, 600Gbps up to 60 kilometres.
This high performance is achieved thanks to Huawei's introduction of a new digital optical signal processor (oDSP) which uses advanced algorithms in its chipset Artificial Intelligence for the coding and modulation of the optical signal.
“The continuous technological updating of our equipment – he explained Paolo Perfetti, Technology director of Open Fiber – allows us to be pioneers in the implementation of innovative technological solutions to serve the needs of operators and consumers. In the Open Factory, the Open Fiber testing laboratory, we are already working to surpass the result achieved today".
