Infinera DTN-X XT Series

The XT Series introduces the industry’s first small-form-factor, server-like meshponder wavelength-division multiplexing (WDM) platforms, which blend sliceable photonics and muxponder functionality to deliver cloud scale WDM along with fine granularity. The XT Series is optimized for delivery of cloud scale network services over long-haul, regional and data center interconnect networks spanning hundreds and thousands of kilometers (km), leveraging 8 quadrature amplitude modulation (8QAM), 16QAM and quadrature phase-shift keying (QPSK) modulations. The server-like XT Series meshponders are developed based on Infinera’s experience in the cloud scale market and seamlessly interoperate with the chassis-based DTN-X XTC Series switching platforms, with their roots in telecommunications networks. The meshponder platforms are powered by Infinera’s fourth-generation Infinite Capacity Engine (ICE4) and support Infinera’s unique Instant Bandwidth technology, sliceable super-channels, in-flight wire-speed encryption and the Advanced Coherent Toolkit (ACT) for improved capacity-reach performance.

Server-like Platform: Meshponder

The XT Series includes the following platforms:

  • The XT-3300 delivers super-channel-based 1.2 terabits per second (1.2T) of line-side capacity for metro, regional, long-haul and data center interconnect networks in 1 rack unit (1RU). It provides reach of 6,000 kilometers (km) in an ultra-compact form factor at 600 millimeters (mm) rack depth, with low power consumption and sliceable photonics for maximum networking flexibility.
  • The XT-3600 delivers super-channel-based 2.4T of line-side capacity for metro, regional and long-haul networks in 4RU with sliceable photonics for maximum networking flexibility and carrier-grade compliance. With redundant controller, 470 mm rack depth, a mix of 100 Gigabit Ethernet (GbE)/OTU4/10 GbE client interfaces and OTN multiplexing, it supports reach of 6,000 km.
  • The XT-500 delivers a 500 gigabits per second (500G) super-channel output with 10 GbE or 100 GbE client interfaces in 2RU, with low power consumption.

The XT Series interoperates with the DTN-X XTC and XT Series, providing a unified end-to-end Intelligent Transport Network portfolio. It can be seamlessly integrated with the Infinera FlexILS line system and offers support for fixed and flexible grid to maximize spectral efficiency, providing up to 25.6T of fiber capacity. It also helps service providers take advantage of colorless, directionless, contentionless reconfigurable optical add-drop multiplexer (ROADM) architectures. This enables super-channel switching at the optical layer, Layer 0, within an optical mesh network, improving overall network switching capability and thus resulting in enhanced network efficiency. Moreover, Instant Bandwidth allows providers to adopt a cashflow-efficient business model in which additional bandwidth can be deployed rapidly with a few mouse clicks when demand increases. There is no need to order, install and deploy additional equipment. New services can be activated remotely in an instant, resulting in faster time to revenue.

The XT Series provides high levels of reliability, low space and power consumption and operational simplicity. It enables network operators to achieve operational scale while reducing the total cost of ownership of transport networks in high-capacity point-to-point interconnect and mesh applications across data center interconnect, metro and long-haul networks.
