Nokia Siemens Networks is the first to demonstrate easy upgrade to 400G optical transport
400Gbit/s successfully transmitted with high spectral efficiency over 600km fiber
Nokia Siemens Networks has demonstrated how FlexiGrid* technology can upgrade optical transport networks to 400G (gigabits per second). The move is aimed to address the rapidly growing demand for bandwidth among operators today. Using FlexiGrid, the company has conducted the industry’s first trial of 400G 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 is demonstrating its optical transport networks at the OFC/NFOEC conference in Los Angeles, California during March 8-10, 2011.
Nokia Siemens Networks used FlexiGrid* and advanced digital signal processing for this demonstration. Once the solution is commercialized, it will allow 400G evolution for operators’ current 10G/40G or 100G DWDM multi-haul hiT 7300 platform and Next Generation Packet Optical Transport Solution (P-OTS)**. In addition, the increased utilization of fiber capacity will drive down costs.
“ 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.”
Nokia Siemens Networks’ hiT 7300 platform is part of the company’s unique Smart Transport*** offering that enables the lowest Total Cost of Ownership (TCO) for operators. Nokia Siemens Networks’ Smart Transport is based on its globally available IP Integration capabilities to plan, install, provision maintain and where needed operate multivendor transport networks. In addition, it includes Nokia Siemens Networks’ own products such as DWDM based optical transport, optical transport network (OTN) switching, TransNet network planning tool and NetAct network management. It is also complemented by IP/MPLS routers from the leading companies.
The FlexiGrid technology incorporated in Nokia Siemens Networks’ hiT 7300 DWDM platform, allows the evolution to 400G networks by dynamically adapting the network’s wavelength grid to the needs of the high-capacity channels. This is done by using the network operator’s existing fiber infrastructure without causing any disruption in service.

Notes to editors:
* The new FlexiGrid technology incorporated in Nokia Siemens Networks’ hiT 7300 DWDM platform since 2011, allows greater flexibility in channel spacing, which is the minimum frequency separation between two multiplexed signals in a WDM network. At present, the channel spacing is hard wired and 50GHz by default . However, this is insufficient to achieve speeds that are higher than 100G. The FlexiGrid technology allows CSPs to dynamically adapt the wavelength grid to the needs of high-capacity transport channels, enabling speeds as high as 400G and beyond.
** Nokia Siemens Networks’ next generation packet optical transport solution (P-OTS) combines the intelligence needed to reliably send information, wherever needed coupled with the huge scale and speed of optical fiber communications. Next Generation P-OTS off-loads IP/MPLS routers connected to the optical transport network by switching traffic in the optical layer instead of the more expensive electrical layer switching by the routers.
*** Nokia Siemens Networks’ DWDM (Dense Wave Division Multiplexing) solution, comprising of the hiT 7300 and TransNet DWDM planning and automation tool, provides a cost optimized, flexible and automated platform, thereby, offering a viable answer to excessive traffic demand, reconfiguration and cost pressure issues. The design principle of the DWDM platform (hiT 7300) is based on high modularity as well as high re-use, thus creating a single platform from metro to core. It also provides network operators with a new level of simplicity for commissioning and maintaining DWDM systems, driving out complexity while providing complete administrator control. Nokia Siemens Networks’ TransNet end-to-end planning tool provides optimal network design, guaranteed performance and automated configuration, resulting in significant OPEX savings, reduced outage time and procedural errors along with an exceptionally low TCO.
With over 100 DWDM customers around the world, Nokia Siemens Networks leads the way and provides a migration path to Terabit Optical Transport, It also provides scaling capacity for channels of 10/40/100 Gbit/s with its platform being open to 400Gbit/s and even more. The company has 12 hiT 7500 customers and 90 hiT 7300 customers.
