400Gbps speeds reached with high spectral efficiency
Nokia Siemens Networks has demonstrated how FlexiGrid technology can upgrade optical transport networks to 400G (gigabits per second).
Using FlexiGrid, the company has conducted the industry’s first trial of 400Gbps data transmission over single mode fiber at a distance of over 600km. The trial was conducted at Nokia Siemens Networks’ R&D lab in Munich, Germany.
Nokia Siemens Networks used FlexiGrid and advanced digital signal processing for this demonstration.
Once the solution is commercialized, it will allow 400Gbps evolution for operators’ current 10Gbps/40Gbps or 100Gbps DWDM multi-haul hiT 7300 platform and Next Generation Packet Optical Transport Solution (P-OTS).
“With the increase in network traffic outgrowing revenue coupled with 100G reaching the limits of spectral efficiency, operators are looking to evolve their network beyond 100G,” said Uwe Fisher, head of optical networks product management at Nokia Siemens Networks.
“We have now reached another milestone, which demonstrates that our hiT 7300 paves the way for operators to easily upgrade their optical data transport networks and allow them to flexibly balance between speeds above 100G and the fiber length along with improving the efficiency of their fiber infrastructure.”
