Infinera unveils the DTN-X, a multi-terabit packet-optical transport (P-OTN) network platform based on 500Gb/s Photonic Integrated Circuits (PICs), and designed for global service providers facing increasing demands for bandwidth driven by video, mobile and cloud-based services.

The DTN-X is purpose-built to integrate switching with DWDM without trade-offs in capacity. The architecture of the DTN-X extends Infinera's DTN in a multi-terabit platform that scales for the future, is simple to operate and reduces the number of elements in the network.

Unabated growth in internet traffic is driving operators to upgrade their networks to 100Gbps and higher speed optical transmission. Infinera's 500Gbps PICs integrate more than 600 optical functions and deliver 500Gbps super-channels, providing a foundation for the DTN-X's superior scale, simplicity and efficiency.

Infinera recently tested the fully functioning 500Gbps PICs on the production network of SEACOM, a leading pan-African telecommunications provider, demonstrating 500Gbps of coherent transmission over a distance of 1,732km (Infinera and SEACOM achieve first ever 500Gbps optical network trial in Africa Over a Distance of 1732km) and earlier this year the company presented test results for a 1Tbps PIC (Infinera Presents on First-Ever Terabit PIC at OFC).

Since most end-user services today are 10Gbps or less, global operators require integrated ITU G.709 Optical Transport Network (OTN) switching to groom traffic onto larger 100Gbps and 500Gbps pipes to maximise network utilisation. The DTN-X will deliver 5Tbps of non-blocking OTN switching in a single bay, and in subsequent releases will be upgradeable to resilient multi-bay configurations providing 100Tbps of non-blocking OTN and MPLS switching. Unlike competitive offerings where integrating DWDM with switching was an afterthought, the DTN-X is designed from the ground up to combine three unique technology building blocks—PICs, custom switching ASICs and intelligent GMPLS software—enabling the DTN-X platform to be flexibly configured with up to 5Tbps of DWDM or service interfaces in each bay, or any combination of the two, without any loss of capacity.

Infinera is introducing a full-rack, multi-bay-ready chassis and a half-rack chassis, both of which are planned for availability in the first half of 2012. The DTN-X is interoperable with the DTN platform and is planned to support 10 Gigabit Ethernet (10GbE), 40GbE, 100GbE, 10Gbps SONET/SDH/OTN, 40Gb/s SONET/SDH/OTN, 100Gb/s OTN, 8/10Gb/s Fibre Channel, and multiple bit rate clear-channel interfaces.

Infinera also unveils new capabilities on the DTN platform to support new services and further increase fibre capacity. These include new 40GbE and 100GbE service interfaces to support high-bandwidth data services. In addition, DWDM line-cards are now available supporting 40Gbps per wavelength coherent optical transmission, enabling the DTN platform to scale up to 6.4Tbps of transmission capacity per fibre. The DTN and DTN-X platforms are designed to provide a seamless transition from 10G-40Gbps and 100Gbps wavelengths, enabling global network operators to migrate their networks according to their bandwidth needs.
