Infinera customers are finding that the DTN is the world's highest density, and most reconfigurable switched DWDM system available today. The DTN is the world's first "digital" Remotely Configurable Optical Add/Drop Mux (ROADM), and is the key building block for implementing the Infinera Digital Optical Network architecture. Designed around Infinera's large scale Photonic Integrated Circuit (PIC) technology, the Infinera DTN integrates scaleable multi-wavelength DWDM transport with fully reconfigurable sub-wavelength digital switching and GMPLS-enabled end-end service intelligence and automation. The result is reduced capital expenditure (CapEx) and operational expenditure (OpEx) and increased service velocity.
Industry leading transmission density with 800Gb/s of add/drop capacity in a single bay.
Rack space translates to OpEx, and quite simply the DTN provides more add/drop capacity per rack inch than the competition as a direct result of Infinera's unique PIC technology.
Sub-wavelength add/drop, muxing and grooming of 155Mb/s to 40Gb/s services at every node with a switching granularity of ODU1 (2.5Gb/s).
Why pay extra for external switches when this capability is integrated into the DTN for free? The DTN allows you to maximize your network utilization, avoid stranded bandwidth, and provide unconstrained service reconfigurability at every node.
Unconstrained add/drop of 155Gb/s to 40Gb/s SONET/SDH, OTN, Ethernet 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-ways junction sites.
Service provider has total choice of network topology with no requirement for external switching equipment.
Ten times fewer field replaceable units.
In real network bids we typically find that we are proposing one tenth the number of field replaceable units compared to our competitors. This translates directly to lower operational costs.
GMPLS-driven Embedded Software Intelligence
Drive down operating costs by using Embedded Software Intelligence for:
Automatic inventory management
Automatic topology discovery
Point and click end-to-end service provisioning
More flexible service protection and restoration
Optical/IP integration via an Optical UNI
The Photonic Integrated Circuit brings the benefits of Moore's law to optical networks.
The strategic benefit it provides is to lower the cost of OEO conversion which facilitates the Digital Optical Network paradigm.
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 with the following benefits
Future Proofs new service types and rates
New services are added 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
