  • Photonic Integration  
    In the world of microprocessors, we have seen tremendous increases in computational power with simultaneous decreases in cost and power consumption resulting from integration and standardized semiconductor manufacturing processes. The integration of optical components and functions into large scale photonic integrated circuits (PIC) and the use of semiconductor manufacturing processes for PICs has been pioneered by Infinera, and shows significant benefits when integrated into a DWDM system. Infinera’s integration approach, first on the DTN at 100G and now on the DTN-X at 500G per pair of chips, enables significant power, space and cost savings for long haul DWDM applications.
  • SD-FEC for Coherent Super-Channels  
    The goal of long haul DWDM transmission is to deliver error-free digital information at extremely high data rates and over very long distances, ideally without the need for regeneration of the signal en route.
  • Bandwidth Virtualization Enables a Programmable Optical Network  

    Bandwidth Virtualization™ in Digital Optical Networks provides a scalable, cost-effective and easy to manage service deliver architecture that contains built-in investment protection for emerging technology enhancements. Based on the use of Photonic Integrated Circuit and Digital Optical Network™ technology, Bandwidth Virtualization decouples the service layer from the optical transmission layer, providing operators with software-based flexibility for provisioning new services; unconstrained reconfigurability, and rapid service turn-up. In addition Bandwidth Virtualization alleviates the complexity, time and cost limitations of hardware-based service deployment. Bandwidth Virtualization provides an avenue for carriers to implement a programmable optical network to rapidly and efficiently deploy new and differentiated services and elevates the service offering beyond commoditized pointpoint transport services.

  • Top Five Things You Need to Know Before Building or Upgrading Your Cloud Infrastructure  

    Over the last several years, the need for bandwidth has grown dramatically across all types of users. Some of the fastest growth is occurring between data centers and between customer sites (e.g., HQ, point-of-presence or co-location site) to data centers and/or Internet Exchange (IX) facilities and is heavily driven by the growth in both public and private Cloud use. Enterprises whose data center interconnection capacity needs are approaching or exceeding 100 Gb/s today have many options to help lower cost and drive scale.

  • A Software Defined Network Architecture for Transport Networks  

    Software Defined Networking (SDN) has had a successful journey from experimental university networks to production deployments, simplifying networks at IP/Ethernet layers within the data center. It is now extending its benefits into the wide area network (WAN) at both the packet layer and the transport layer. SDN enables centralized and programmatic control of the underlying packet and transport layers to provide increased automation to reduce OpEx, optimize the network to reduce CapEx, and deliver new services to increase revenues and improve customer retention. With the proper architecture and implementation, SDN can also support service providers who want to transform to a DevOps model for rapid service creation and deployment for a better competitive posture in the marketplace.

  • The Evolution of Next-Gen Optical Networks  

    Cable operators have made significant progress in migrating from 10 Gb/s optical transport waves to 100 Gb/s waves in their core networks. 100G waves allow 8 Tb/s or more of capacity to be carried on traditional fiber using the standard 50 GHz C-Band ITU-T G.694.1 grid. However, bandwidth growth projections already indicate that 8 Tb/s of capacity per fiber will be insufficient in the near future and that the operational costs of deploying so much capacity in 100G increments can be high. To address the emerging capacity requirements and to achieve better operational efficiency, next generation optical networks will utilize a flexible grid channel plan (variable-width optical super-channels) and terabit scale super-channels implemented with the appropriate modulation, depending on reach requirements, and incorporating software controlled optical switching functions.

  • The New Packet-Optical Core for a Software-driven World  

    Over the past decade, IT infrastructure has seen a dramatic shift from local resources to those located in a third-party facility. Whether we receive them at home or on our mobile phones, service providers offer hardware-free services that reside somewhere on the network, including storage of our personal files, streaming of personal and commercial video and, of course, photo albums and email. The acceleration of cloud adoption, as evidenced by the tremendous growth of Infrastructure, Platform & Software-as-a-Service (IaaS, PaaS and SaaS) offerings among technology providers, is having a profound impact on IT and network architectures.

  • The Magic of Big Capacity: Boosting Railroad Infrastructure ROI with Telecom Services  

    Infinera enables owners of optical fiber networks to significantly expand their capacity, offer new revenue generating services and match capital costs to capacity demand. Infinera's services include a full range of design, turnkey network upgrading and installation of equipment, remote management and on-demand switching on of pre-installed capacity. This white paper identifies some of the revenue opportunities available to holders of railroad rights-of-way.

  • A Comprehensive Approach to Multi-layer Transport Network Automation  

    Service providers continue to face staggering increases in bandwidth, driven primarily by video and cloud combined with increasingly competitive broadband and mobile access speeds. This growth requires ongoing CapEx investment in the network at both the IP/MPLS layer (Layer 3/2.5) and the OTN and DWDM transport layer (Layer 1/0) so that service providers can continue to deliver high quality network experiences to their customers. Wall Street, on the other hand, continues to demand strong financial performance with new revenues and flat or declining CapEx-to-revenue and OpEx-to-revenue ratios.

  • Better Network Economics with IPoOTN  

    It's a given that IP traffic is growing exponentially. All industry analysts and bodies agree on the tremendous surge of traffic - IEEE estimates a rate of more than 30% compounded annually. This is impacting the infrastructure that serves to transport it in different ways - the IEEE 802.3 Industry Connections report from 2012 outlined how the core network and server input/output links are reacting to this deluge. From the figure, it is evident that core network scaling is forcing service providers to have a wideranging discussion about how to best optimize, evolve and converge packet-optical networks in order to reduce the total network cost.
