Components of Agile Optical Networking
Accelerate service delivery and automate operations
For your network to be dynamic and services-oriented, it has to be highly intelligent — with seamlessly integrated planning, commissioning, service turn-up and maintenance. Optical network intelligence enables continuous optimization of your network’s self-organization, monitoring and restoration of assets to ensure maximum network efficiency and cost-effectiveness with faster time to revenue.
Ensuring maximum network efficiency and cost effectiveness are key drivers for creating smarter optical networks. Agile Optical Networking responds to the dynamic nature of emerging services and the escalating scale of network traffic. Leveraging the Alcatel-Lucent 1830 Photonic Service Switch (PSS) and its network planning tools, Wavelength routing engine (WRE) software and unified network management, Agile Optical Networking enables rapid service delivery and ‘always-on’ network monitoring. It brings the intelligence and adaptability to allow for automated, real-time decision making in response to users’ needs. Optical network intelligence opens the door to a true services-oriented networking model that offers you faster time to revenue, simpler operations and greater service availability.
Network planning and engineering tools
Making the optical network more intelligent requires a robust toolkit to support the entire lifecycle of service planning, deployment and management. For instance, although initial traffic demands may be estimated, they can change drastically over the life of the network. Network operators need tools to confidently manage dynamic traffic growth while assuring all service requirements are met.
The Alcatel-Lucent 1390 Network Planning Tool (NPT) provides complete lifecycle planning for multilayer optical transport, allowing network operators to plan for various levels of traffic growth and evaluate hypothetical network scenarios. It facilitates the planning of nominal routes to ensure optimal, deterministic control of traffic routes. It generates a 'bill of material' featuring a list of the equipment and modules required for a given traffic profile. And the 1390 NPT ensures traffic is routed at the most economical layer, reducing overall network cost in addition to generating all provisioning and commissioning parameters for each layer for automatic download to network elements.
Wavelength routing engine (WRE) software
With the ability to support SDN and offload repetitive time-critical tasks from centralized managed systems, WRE software increases your network’s reliability and responsiveness to services requests. It also reduces the effort needed to manage the network.
An industry leader in the standardization, testing and deployment of optical network control solutions, Alcatel-Lucent works in close collaboration with service providers worldwide to develop the latest network control functionality. While most vendors’ optical network control solutions function in a single technological layer, the 1830 PSS network control supports true multi-region and multilayer networking — unlocking the full potential of network control by jointly optimizing and controlling packet, electrical and photonic switching layers.
Unified network management
Unified network management takes service providers beyond the traditional boundaries of element, network and service management. Our unified network management capability offers:
- Fast and easy provisioning from access to core, reducing time-to-market and increasing flexibility when launching new and advanced services while minimizing the risk of misconfigurations
- Simpler and more proactive troubleshooting to help resolve problems before they affect customers
- Cost-effective integration into the existing operational environment, enhancing workflows and processes while increasing productivity and flexibility
Delivering services at the most economical layer
Your network applications come in many protocols and sizes, and no single switching layer can address every situation. Let our multilayer switching provide you with high-capacity packet, electrical and photonic switching in a single platform, with grooming and aggregation at the most economical layer. Feel confident that our non-blocking switching will ensure your capacity can scale, resources aren’t stranded and new service demands will be met.
Although emerging services are delivered in packets to end users, connecting users to the network requires a blend of packet, electrical and photonic switching. With Agile Optical Networking, you can leverage the appropriate switching layers to suit specific needs and your network structure — all on a single, versatile platform.
Packet optical transport

Converged terabit OTN/WDM
Enabling the terabit era
The 1830 PSS has a multilayer architecture that combines photonic and electrical modules with an integrated WDM/OTN platform. The result is a converged solution that offers best-in-class multi-terabit electronic switching functionality as well as best-in-class WDM photonic capabilities. Multilayer GMPLS intelligence and network planning tools optimize network cost and design. Layer 0/1/2 networking capabilities and linkages between layers ensure transport at the most economical layer. The result is maximum resource optimization and wavelength use, flexible client service assignment, ultra-fast restoration and coordinated network operations. Functionalities include:
- Multi-terabit OTN switching: Enabled by an industry-first 1 Tb/s OTN chip, the non-blocking matrix of the 1830 PSS supports delivery up to 4 Tb/s and is upgradable to a capacity of 8 Tb/s. The scalable, universal switching fabric supports multiple networking technologies (such as OTN, SDH/SONET and Carrier Ethernet) and the transport of any mix of client traffic, including OTH ODUk, GbE and 10 GbE, SDH/SONET up to STM-64/OC-192, and 40 Gb/s and 100 Gb/s signals.
- Photonic switching: Through flexible photonic switching, any wavelength can carry any services in any direction — a feature not found in previous ROADM platforms. Through the use of colorless, directionless, contentionless and flexible spectrum (CDC-F) ROADM technology, there are no more limitations to the ROADM’s ability to scale or provide simultaneous colorless, directionless and contentionless features.
Network photonically at 100G and beyond
Take your photonic network to 100G and beyond. The Alcatel-Lucent 400G Photonic Service Engine (PSE) delivers peerless 100G, 200G and 400G performance. Our 1830 Photonic Service Switch (PSS) allows any service to travel over any wavelength in any direction. And our Wavelength Tracker enables complete photonic service management anywhere in the network — without terminating wavelengths.
With Agile Optical Networking, wavelengths do not just provide bulk transport — they are the foundation of a fully networked photonic infrastructure. Managed agile photonics combine high-performance coherent transport with flexible photonic switching to cost-effectively deliver emerging services. And comprehensive photonic monitoring and management delivers wavelengths automatically, efficiently and error-free.
Flexible photonic switching
Any service, any wavelength, any direction
If optical transport wavelengths are the arteries that carry the lifeblood of emerging services, then flexible photonic switching is the heart that powers and directs those wavelengths. In this case, flexibility means any wavelength can carry any service in any direction — something not possible with present-generation ROADM devices. By reducing overall hardware complexity, our wavelength routing equipment and software make it possible to build colorless, directionless, contentionless and flexible-spectrum (CDC-F) devices that can route any wavelength in any direction, with spectral flexibility and without contention.
400G Photonic Service Engine
Four times the speed. Capacity to spare.
The Alcatel-Lucent 400G Photonic Service Engine (PSE) is the first-ever commercially available electro-optics chip capable of carrying up to 400 Gb/s of traffic. Versatile and scalable, it dramatically boosts the performance of 100G networks today while laying the foundation for 400G transport tomorrow. Designed specifically for the Alcatel-Lucent 1830 PSS, the 400G PSE accelerates network speeds fourfold to deliver the highest possible performance per wavelength at 100G.
By minimizing space and power requirements, the 400G PSE lets you evolve your network without costly re-engineering. It is backward compatible with current 100G systems — whether newly lit or brownfield fiber photonic lines — at 10G, 40G and 100G. And it has the ability to pack more wavelengths into every fiber through waveform engineering, with the potential to increase spectral efficiency and reduce power consumption by as much as 33 percent.
The 400G PSE's market-first transmit digital signal processor (DSP) enables waveshaping to improve tolerance to nonlinearities. It can be tuned to optimize performance per route — for example, by dialing pre-compensation up or down to address chromatic dispersion and extend reach in existing compensated networks.
Monitor and manage your wavelengths from any point in the network
With so much mission-critical data riding on your optical wavelengths, even the slightest network disruption could be costly. Being able to automatically assess the health of the photonic network and quickly pinpoint the location of any fault — without terminating any wavelengths — has become imperative.
Wavelength Tracker is a unique photonic management tool for the 1830 PSS that automates the commissioning, turn-up and supervision of wavelengths.
By allowing every wavelength to be uniquely identified and monitored without being terminated or regenerated, Wavelength Tracker offers an integrated view of all wavelengths at different points across your network. This makes it easier to trace wavelength behavior, isolate faults and monitor performance — including latency and optical signal-to-noise ratios. Wavelength Tracker also provides end-to-end photonic monitoring at the fiber and wavelength levels for precise fault isolation, avoiding misconnections and same-color wavelength collisions. This supports continuous and autonomous in-service optical power balancing, alarming and control of the photonic line.
