- 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.
- Data Center Interconnect for the Enterprise Hybrid Cloud
The world is moving to the cloud, but there are many clouds and many paths to the future. Most enterprises are planning hybrid cloud strategies, incorporating both public and private cloud infrastructures and using multiple cloud services. In a hybrid multi-cloud environment, the data center interconnect networks connecting the clouds become a critical component of IT infrastructure. Increasingly, enterprises are looking to high-capacity optical interconnection technologies to ensure that they can connect all the pieces of their hybrid cloud with security, scalability, performance and control.
- The Evolution of Mobile Fronthaul to Support RAN Architecture Migration to 5G
It is widely understood that there is rapid bandwidth growth in wireless networks and there is plenty of literature detailing the likely path that radio architecture in the RAN will take to accommodate this growth. Technologies like coordinated multi-point (CoMP), carrier aggregation, and more complex and dynamic multipleinput multiple-output (MIMO) schemes will allow radio access networks to scale to accommodate immense amounts of bandwidth per handset as rollouts of 4G and 4.5 Long Term Evolution Advanced (LTE-A) networks are completed and operators ultimately move to 5G.
- IHS TECHNOLOGY Optical Network Hardware Vendor Scorecard Excerpts
The only report of its kind, this Scorecard evaluates the top optical hardware vendors on criteria using actual data and metrics, including direct feedback from buyers, vendor market share, market share momentum, financials, brand recognition, reputation for innovation, and other benchmarks. This approach eliminates subjectivity and ensures vendors are assessed accurately and fairly.
- Network-as-a-Service: SDN-enabled L1 Virtual Networking
Cable operators have expanded their enterprise service offerings to include multipoint managed networks for enterprises requiring interconnect networks, which may be metro, regional, or national in scope. In some cases, these enterprises not only want more visibility into their network infrastructure and service performance, but also want the ability to provision and control their services and bandwidth in real time. Due to the complexity of sharing services among several enterprises (and even residential services) on a single underlying network infrastructure, allowing enterprise customers this degree of control has been difficult to accomplish due to security, reliability, and management issues.
