  • Cognitive Networking in the Access: Deploy DAA Faster than Ever  
    Auto-Lambda brings the vision of Infinera’s Infinite Network to the edge of optical networks today. This technology automates wavelength tuning during network rollout or in service/sparing scenarios by enabling cognitive optics –optics that learn their required wavelength directly from the network – bringing significant savings in both capital and operational costs. Infinera has engaged Jack Burton of Broadband Success Partners to study Auto-Lambda with a view to addressing its operational advantages. Jack’s analysis is primarily focused on DAA network migration within cable MSO networks, but the results are equally applicable in other fiber deep access networks, such as 4G/5G mobile networks.
  • 5G Network Architectures: From X-haul Transport to Multi-Layer Service Slicing  
    5G introduces new network architectures and service requirements that will have major implications for how operators design transport networks. As communication service providers (CSPs) are in the early stages of rolling out 5G, Mobile World Live conducted an online survey of mobile and fixed-line network operators and mobile virtual network operators (MVNOs) to understand current strategies for 5G transport networks. The survey revealed that resolving 5G transport issues is a high priority for CSPs and showed that while CSPs are initially concerned with meeting capacity and low latency requirements in the near term, they are also preparing to support advanced 5G features such as X-haul, network slicing and Multi-access Edge Computing (MEC).
  • The Ultimate Guide to Nyquist Subcarriers  
    Coherent optical transmission has delivered a dramatic enhancement in the capacity-reach product for long-haul and subsea cables. The first wave of coherent systems reached the market around 2011 and delivered a tenfold increase in capacity,with 10 gigabit [10G] wavelengths becoming 100G wavelengths. The first wave of coherent systems located all of the digital processing power in the receiver. Today, a second wave of coherent systems has both transmitter- and receiver-based processing, and can deliver around 30 times the capacity of non-coherent technology.
  • Operator Strategies for Disaggregation  
    5G introduces new network architectures that will have a profound impact on radio, core and transport network design. As communication service providers (CSPs) begin to roll out 5G, Mobile World Live conducted an online survey of mobile and fixed-line network operators and mobile virtual network operators (MVNOs) to understand current strategies for the 5G transport network, and, specifically, the role that disaggregated architectures play in transport network planning. The survey confirmed the significance of the transport network for supporting 5G strategies as well as revealed CSP aspirations for disaggregation of switching and routing resources in 5G transport networks and the operational considerations that need more attention.
  • Open Optical Networks: Doing More With Less  
    Open optical networking has moved rapidly from concept to reality, opening up new opportunities for network operators to maximize the return on their network investments while improving their service agility—in other words, to do more with less. This white paper describes the business value – including reduced CapEx and OpEx -- that can be achieved by using open optical networking techniques in two different scenarios. Learn more about how network operators around the world are adopting open optical technologies, transforming their networks to become more open, competitive and profitable.
  • The Three Myths of Optical Capacity Scaling: How to Maximize and Monetize Subsea Cable Capacity  
    This white paper tests common myths about how scaling baud rate, modulation order and integration affect spectral efficiency and total subsea fiber capacity. Learn which of these myths are false and which have some truth to them, and explore how submarine network operators can maximize total fiber capacity to enhance the economics and competitiveness of a submarine cable business model.
  • Future-proof Open Line Systems for Cloud Scale Networks  
    Network operators with large-scale optical transport networks have traditionally relied on a single optical transport supplier to provide end-to-end optical systems within each domain of their network. While integrated optical systems have demonstrated advantages in maximizing performance and minimizing operational complexity, there is renewed interest in optical system disaggregation, especially in open line systems. This white paper examines the drivers and requirements for an open line system that will meet the most advanced needs of network operators today while offering future-proofing for tomorrow.
  • The Benefits of Cloud Scale Transport Networks  
    Continued growth in network bandwidth demand is driving the need for new innovations to support the massive scale of on-demand network traffic. New innovations in coherent optical technology have been fueled by advancements in electronics and cutting-edge photonics using large-scale photonic integration. The next generation of multi-terabit super-channels and sliceable photonic technologies creates highly scalable and efficient network architectures that blend the best of web scale technologies with those of telco-grade technologies. Network modeling analysis shows that a multi-terabit photonic integrated circuit (PIC)-based super-channel approach using sliceable photonics technology with an optimal mix of meshponders and Optical Transport Network (OTN) switching functions can deliver 56 percent lower total cost of ownership (TCO) to network operators.
  • The Next Generation of Coherent Optical  
    Infinera’s new Advanced Coherent Toolkit enables operators to improve their fiber capacity-reach performance with Nyquist subcarriers, SD-FEC gain sharing, matrix-enhanced phase shift keying (ME-PSK) modulation and other techniques. The toolkit is enabled by the Infinera optical engine, which combines large-scale photonic integrated circuits (PICs) and FlexCoherent™ Processor ASICs, two key technologies that enable 500 Gb/s and Terabit super-channel transmission and help operators scale intelligent transport networks.
  • The Evolving Economics of 100G Transport Networks  

    The bandwidth efficiency and relative costs for 100 Gb/s WDM transport and switching architectures are compared in North American and pan-European long-haul networks. The first architecture uses muxponders and ROADMs for end-to-end wavelength transport with no digital sub-wavelength grooming. The other two utilize digital OTN switching, as either a standalone OTN switch or a converged integrated WDM/switch system, to efficiently groom services onto WDM wavelengths. Results show the integrated WDM/switch architecture utilizes the fewest WDM wavelengths and client service interfaces, and an integrated WDM/switch architecture using photonic integrated circuit technology provides the lowest operational costs.
