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.
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 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.
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.
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.
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.
Low Latency – How low can you go? Low latency has always been an important consideration in telecoms networks for voice, video and data, but recent changes in applications within many industry sectors have brought low latency right to the forefront of the industry. This white paper will address the drivers behind the recent rush to low latency solutions and networks and will consider how network operators can remove as much latency as possible from their networks as they race to zero latency.
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 wavelength-division multiplexing (WDM) 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.
