Networks that can be turned up in days, services that can be activated in minutes and a pool of bandwidth that is always available on demand for any service from 155 Mb/s to 100 Gb/s are three simple reasons why Infinera customers continue to rely on the Infinera DTN Digital ROADM. The Infinera DTN remains the first platform in the world to combine the speed of optics with the simplicity of digital networking to deliver the world's first WDM platform that includes a fully integrated, non-blocking, Colorless, Directionless and Contentionless Reconfigurable Optical Add/Drop Mux (ROADM). Designed with Infinera's large scale Photonic Integrated Circuit (PIC) and an integrated OTN switch, the Infinera DTN converts the network capacity into a pool of resources that can be tapped on demand. By leveraging GMPLS-based network intelligence and a plug-and-play architecture, operators can deliver any service to any customer on demand.

The result is reduced capital expenditure (CapEx) and operational expenditure (OpEx) and increased service velocity.

DTN Features:
Transmission scalability up to 6.4Tb/s per fiber Eliminate capacity exhaust and maximize your fiber plant with a seamless upgrade to support 10Gb/s and 40Gb/s wavelengths on the same fiber.
800Gb/s of add/drop capacity in a single bay Reduce OpEx through the use of less space while still delivering more add/drop capacity per rack inch than the competition as a direct result of Infinera’s large-scale photonic IC technology.
Built-in bandwidth virtualization automatically optimizes your network Never leave any network capacity stranded or unused, thanks to Infinera’s bandwidth virtualization. Using the integrated switch, the DTN allows you to optimize your network and maximize your revenue opportunity by grooming any service from 155Mb/s to 100Gb/s at every node.
Any service including SONET/SDH, OTN, Ethernet, video and SAN services at every node The Infinera DTN enables customers to offer a wide range of services from a common, high-density optical service platform.
Support for terminal, 2-way, 3-way and 4-way junction sites The service provider has total choice of network topology with no requirement for external switching equipment.
Fewer field-replaceable units Experience has shown that in real-world networks the Infinera solution typically requires one-tenth the number of field-replaceable units compared to those of competitors. This translates directly into lower operational costs.
GMPLS-based network intelligence Drive down operating costs by making the network self-aware including:
  • Automatic inventory management
  • Automatic topology discovery
  • More flexible service protection and restoration
  • Optical/IP integration via an optical UNI
Photonic integrated circuits (PICs) Brings Moore's Law to optical networks. The strategic value of a PIC is to enable low-cost OEO conversion, which facilitates and enables integrated switching as well as greater automation, control and performance. Also brings direct benefits of reduced size, power, costs and improved reliability. Results in lower CapEx, OpEx and a more flexible optical network.
Separation of line and tributary interfaces Decouples the service interfaces from the DWDM line interfaces enabling the entire line side to act as a pool of bandwidth resources for any service.
  • Enables fast turn-up of any service
  • Supports any service from 155Mb/s to 100 Gb/s over any line-side technology (10G or 40G wavelengths)
  • Future-proofs new service types and rates
  • Adds new services without affecting existing services
  • Simplifies inventory and sparing as line interface is not tied to the service
There is no stranded capacity or DWDM line cards as the service type changes
  • Sonet/SDH to Ethernet evolution
  • OTN client interfaces
  • New SAN services
  • New digital video services
Programmable coherent 40Gb/s waves with FlexCoherent modulation Infinera FlexCoherent enables operators to select their modulation scheme per wavelength, which optimizes reach versus the spectral efficiency over a given route. This translates into optimal ROI of your fiber assets.
