Nokia Siemens Networks' Optical Transport products employ Dense Wave Division Multiplexing (DWDM) technology. DWDM enables the transmission of multiple wavelengths over 1 fiber, each one carrying 2.5G, 10G, 40G and in the near future 100G. This substantially reduces the total cost of ownership and increases capacity.
Our DWDM products lower the cost of electrical regeneration within the network by using pure photonic switching. At 10 Gbps 80% power savings can be achieved compared to optical-electrical-optical transformation.
Traditionally, customers build separate metro and long-haul DWDM networks using different products. Metro products are often cost-optimized for shorter distances, supporting 2.5G and 10G transport with 40 channels of capacity. Long-haul DWDM systems are typically optimized for longer distances, 10G and 40G transport, and up to 80 channels.
Nokia Siemens Networks' multi-reach DWDM platform is optimized for metro, regional, and long-haul networks. The multi-reach architecture allows transport services to be provisioned between end-points based on service demand—not arbitrary borders between metro, regional, and long-haul DWDM networks. By eliminating the need for separate metro and long-haul systems operating expenses are reduced. Using elements from the same portfolio, highly cost efficient and simple passive DWDM can dramatically improve the use of existing fiber networks.
Drive down operating costs through automation
Customers can make significant savings (up to 250 Euro per site) through our industry leading 'TransNet' remote planning and provisioning tool. Commissioning data calculated by the tool as well as customer-specific default settings can be downloaded to all network elements via the network management system with a single mouse click. A final automation step verifies that network elements were installed and configured as specified by the
planning tool. The result is that the need for training, manual patching and engineer site visits ('truck rolls') are minimized.
According to data compiled by the Federal Communications Commission (USA), the level of network outages caused by manual procedural errors is about 20%. These errors can jeopardize service level agreements with costly consequences. With Nokia Siemens Networks DWDM commissioning becomes automated - simply plug in the cards, connect the fibers to the port and all the rest is done with one mouse-click. There are no onsite measurements and no typing. Automated bandwidth provisioning via GMPLS also helps to significantly reduce outage times, and procedural errors.
Power savings with photonic switching
Our DWDM products lower the cost of electrical regeneration within the network by using pure photonic switching. At 10 Gbps 80% power savings can be achieved compared to optical-electrical-optical transformation.
Reduce time to market
With its SURPASS hiT DWDM platform, Nokia Siemens Networks allow you to dramatically reduce the time to deploy new networks and services. The delivery of fully equipped, pre-configured racks and pre-tested equipment out of the factory, plug and play on site, and automation in network maintenance and fault management all help to reduce the time to market. In addition easy and fast remote service provisioning and upgrades are possible through remote wavelength switching.
