Game-changing Innovation for Next-generation Networks
XR optics is a revolutionary technology purpose-built to break the inherent limitations of traditional point-to-point optical transmission solutions. XR optics paves the way for disruptive network economics as 5G, fiber deep, and hyperscale cloud connectivity impose new challenges on operators. With game-changing innovation in coherent optical subcarrier aggregation, XR optics introduces a new pluggable and software-enabled architecture designed to radically reduce the cost of deploying and operating optical networks. XR optics enhances deployment flexibility as the same coherent pluggable can be software-configured to operate in point-to-point or point-to-multipoint configurations.
XR optics is an open technology initiative with the support of network operators, equipment manufacturers, and subsystem manufacturers.
Simplify Transport Networks
With coherent subcarrier aggregation (CSA) and the ability to efficiently optimize aggregation networks for point-to-multipoint traffic patterns
Reduce Capital, Space, and Power
Use a single high-speed transceiver to simultaneously send and receive independent data streams to/from numerous low-speed transceivers
Eliminate Intermediate Aggregation
Eliminate costly optical-electrical-optical network elements (switches and routers) required to “up-speed” lower-speed traffic
Seamlessly Upgrade Capacity
With programmable software control, seamlessly upgrade transmission speeds between hub and spoke locations as demands evolve
Solving a Fundamental Problem
Since the inception of optical networking, there has been a significant misalignment between actual traffic patterns at the network edge and the technology used to transport that traffic. Network traffic patterns at the edge of the network are overwhelmingly hub and spoke – i.e., numerous endpoints generate traffic that is aggregated by a small number of hub locations. In contrast, optical connectivity solutions have been implemented using strictly point-to-point technology. The result is an extremely inefficient transport architecture that requires large numbers of bookended transceivers, as well as numerous intermediate aggregation devices to up-speed traffic flows.
Providing Significant Savings for Network Operators
With XR optics, network operators will be positioned to dramatically reduce the number of transceivers in the network, eliminate the need for costly intermediate aggregation devices, and more efficiently optimize optical transport infrastructure for hub-and-spoke end-user traffic flows, resulting in TCO savings of 70% or more.
Infinera’s suite of vertically integrated ICE-XR pluggables leverages XR optics technology to offer network operators the performance, scale, and efficiency critical to delivering differentiated 5G, enhanced broadband, and next-generation cloud and business services.
Overview of XR Optics
XR optics introduces a paradigm-shifting ability to enable more cost-efficient optical point-to-multipoint networks, which can dramatically lower the cost and complexity of access, metro, and even core networks.
