Wave2Wave Launches Robotic Optical Switches for Data Centers

Wave2Wave Solution introduced a line of robotic optical switches for automating physical fiber connections in high-density data centers.

The Wave2Wave "ROME" Robotic Optical Management Engine platforms, which are offered in three sizes, enable full control of physical fiber connections, allowing changes to be made automatically, remotely, quickly, and without manual intervention.  The robotic systems are designed in 19-inch chassis. The company said its system can be integrated with Software-Defined Networking (SDN) or network management software.

“Today’s digital trends are putting pressure on data centers, and even more pressure on the network architects who design and upgrade them,” said David Wang, founder and CEO of Wave2Wave. “ROME is a game-changing tool. It reduces the physical cabling in the traditional data center infrastructure by more than 10 times, allowing flexibility, intelligence and control that never existed before.”

ROME 500 is now available worldwide, and ROME 1000 and 2000 will become available in the second half of 2016.

ALU Intros Flexible Wavelength Routing on its 1830 PSS

Alcatel-Lucent introduced a wavelength routing solution that can be deployed on its 1830 Photonic Service Switch (PSS), which the company said brings greater flexibility to the optical transport network while reducing CAPEX compared to electrically-switched alternatives.

The wavelength routing solution consists of specialized Colorless Directionless Contentionless-FlexGrid (CDC-F) hardware and Wave Routing Engine (WRE) software. The WRE software provides end-to-end wavelength routing, deployment, and management capabilities. This includes unique in-band per wavelength OAM capabilities to allow for efficient monitoring of wavelength connectivity and support the rapid diagnosis and troubleshooting of potential wavelength connectivity issues. The solution can be scaled from 100G wavelengths to 200G wavelengths without changing equipment required to route wavelengths.

ALU noted that Verizon has chosen the 1830 Photonic Service Switch (PSS) for its ultra-longhaul, core optical network. The company said Verizon selected its 1830 PSS converged WDM/OTN/Packet based-platform as part of its transition to an optical converged infrastructure to address traffic growth and enable faster and less expensive deployment of new services.

“Operators need unlimited network dynamism and scale. A programmable IP/optical fabric is essential. Our wavelength routing technology is a foundational ingredient in providing the unparalleled flexibility with massive automation and increased efficiency that are needed in the optical layer. This solution provides unconstrained wavelength networking and can be deployed at scale,” stated Brian Fitzgerald, Senior Vice President, Global Solutions, Alcatel-Lucent.

CALIENT Debuts LightConnect Fabric Manager Software

CALIENT Technologies introduced its LightConnect Fabric Manager interconnect orchestration software for its S-Series family of Optical Circuit Switches (OCS) for intra-data center connectivity .

The LightConnect orchestration software creates an optical fabric that allows racks or rows of compute resources to be shared between physical Pods across the data center to accommodate varying workload demands.

To enable the OCS-Powered LightConnect Fabric, CALIENT is announcing the new LightConnect Fabric Manager. Core functions of the Fabric Manager include a topology manager and a cross-connect manager. The topology manager maintains a database of the data center network topology including which layer 2/3 switches and ports are connected to specific optical ports on the LightConnect Fabric.

Similarly, the cross-connect manager maintains a complete database of all optical cross connects in the LightConnect Fabric. Together, these two core functions and their databases allow the Fabric Manager to maintain a complete view of overall topology and optical connectivity in the data center.

The Fabric Manager also maintains a consolidated dashboard summary with operational status of all optical circuit switches including alarms, events, and port utilization. The Fabric Manager is a CentOS-based Linux Application, capable of running on off-the-shelf hardware or any virtual machine

“Operational cost efficiency is a compelling competitive advantage in cloud data centers, which makes any innovation that improves compute economics – the biggest contributor to cost – an essential consideration for data center architects and managers,” said Atiq Raza, Chairman and CEO of CALIENT. “Together, the new LightConnect Fabric and Fabric Manager enable a completely new paradigm in data center design and optimization that will support tremendous improvements in server and storage utilization. It is simply not possible to achieve these results with existing layer 2/3 switching solutions, because the round-trip latency of packet-switching is several microseconds every time the hop is made and that is far too great a penalty.”

CALIENT Develops OpenDayLight Controller for Optical Switches

CALIENT Technologies introduced a software controller to facilitate dynamic reconfiguration of the optical network layer to handle the "elephant flows" typically caused by data replications, storage migrations, and movements of big data sets in Hadoop distributed file systems. These elephant flows can overflow buffers on conventional packet switches.

CALIENT said its new Optical Topology Management Controller, which built using the OpenDayLight framework, allows efficient optical topologies to be built on demand, optimizing access to compute and storage nodes to achieve maximum utilization of these critical resources.  It also lays the foundation for hybrid network fabrics in which CALIENT’s S-Series optical circuit switches augment third-party packet-based networks.

With the addition of traffic analysis and traffic engineering capabilities (planned for early 2015), the controller will support the full hybrid packet-optical network, in which the optical layer is reconfigured dynamically to create optical “express” paths that offload highly persistent traffic flows from the L2/3 packet network.

The new CALIENT controller will be used in conjunction with the company’s S-Series family of optical circuit switches. The S320 flagship is a 320-port optical circuit switch used to create an all-optical network fabric with total throughput of more than 32 terabits per second. The switch allows any-to-any, layer one network connections with almost no latency and can be reconfigured on demand under software control. Each switch port is transparent to bit rate and can support data speeds to 100 Gbps and beyond.

“We’ve seen tremendous customer interest in the powerful value proposition of the dynamically reconfigurable optical layer offered by our S-Series optical circuit switches, but the stumbling block has been the lack of a controller to allow applications and traffic patterns to drive and orchestrate the new topologies,” said Daniel Tardent, Vice President of Marketing at CALIENT. “Our new Optical Topology Management Controller is the missing link and we’re now moving ahead on a number of proof-of-concept deployments with our customers.”

CALIENT adds OpenDaylight Plugin to SDN-Controlled Hybrid Packet

CALIENT Technologies announced a new plugin for the OpenDayLight (ODL) platform for providing programmatic control of it S-Series optical circuit switches. This builds on CALIENTs existing support for the OpenFlow API by extending the OpenFlow protocol to support circuit switching.



CALIENT's hybrid packet-optical platform adds an optical circuit switch to packet-based data center networks specifically to handle offloading of persistent data flows through express optical-layer paths.  The company said its new OpenDayLight plugin will allow applications and external controllers using the ODL framework to control CALIENTs S-Series switches via standard published OpenDayLight REST APIs, thus simplifying deployment in software defined data center networks.

OpenDayLight provides a very flexible software framework for controlling hybrid packet-optical networks and so it makes sense for CALIENT to pioneer the development of plugin functionality to support optical circuit switches,said Jitender Miglani, Vice President of Engineering for CALIENT. CALIENT intends to contribute this and future plugins to the open-source community to help harness the power of SDN in data center and metro networks.

In a future release, CALIENT will add a circuit manager to OpenDayLight. Circuit manager is a service with northbound REST APIs that interfaces with external orchestration engines/controllers that may want to manage CALIENTs S-series switch as part of their native application.

Huawei Releases Wavelength-based Multidimensional All-optical Cross-connect

At the OFC 2014 show in San Francisco, Huawei showcased a wavelength-based all-optical cross-connect technology that operates in 8-dimensions (80 waves per dimension).  The optical cross-connect prototype implements a free cross-connect of 640 x 640 waves.

Huawei said its optical cross-connect prototype uses an industry-leading optical engine that enables a programmable million-pixel array to be integrated into a 1 cm2 silicon wafer. This is like integrating a million tiny mirrors into a space no larger than a coin; the engine can then control the cross-connect directions of the wavelengths by manipulating these "mirrors".

The innovation is seen as an important step in the evolution from transport networks to all-optical networks.

Infonetics: Carrier Router/Switch Market Lackluster in Q1 but Healthy

Pushed lower by weakness in Europe, global service provider router and switch revenue declined 17% in 1Q13 from 4Q12, and is down 6% from the year-ago quarter (1Q12) but is expected to grow at 8.8% CAGR through 2017, according to a new report from Infonetics.

“The 1st quarter is normally down for routers and carrier Ethernet switches, so it’s better to look at the longer-term trends,” explains Michael Howard, principal analyst for carrier networks and co-founder of Infonetics Research. “The main growth drivers – the transition from TDM to packet and rising video traffic – are still in effect, the U.S. economy is slowly improving, and a number of large operators in the Euro zone intend to spend. Given these factors, we expect the router and CES market to grow at an 8.8% CAGR through 2017."

Some highlights of the report:
  • North America was the only geographic region to buck the usually down Q1, posting a 7% sequential gain
  • EMEA (Europe, the Middle East, and Africa), Asia Pacific, and CALA (Caribbean and Latin America) all declined by double digits in 1Q13
  • Cisco maintains its strong hold on the #1 spot in the overall carrier router and switch market with 39% revenue share in 1Q13
  • Meanwhile, the fight for the next 3 positions in the carrier router and switch market remains tight, with less than 1 percentage point separating Alcatel-Lucent, Huawei, and Juniper
  • Alcatel-Lucent edged ahead of Huawei for 2nd place in 1Q13
  • Private router company Compass-EOS recently announced NTT as a customer for its new core router that provides terabit-per-second connectivity to facilitate software-defined networking (SDN) and network function virtualization (NFV)

Southern Cross Cable Deploys Calient's Photonic Switch

Southern Cross Cable Networks has deployed CALIENT Technologies' FiberConnect 320X photonic switch on its trans-Pacific network. The switch makes it possible to remotely reconfigure the fiber network in seconds, adding further protection in the event of fiber breaks or repeater/transponder failures.


The Southern Cross Cable Network is a fully protected fiber-optic cable network linking Australia, New Zealand, Fiji and Hawaii directly to the U.S. west coast. The network has 28,900 km of submarine and 1,600 km of terrestrial fiber optic cables, operated in a figure eight configuration. The network has a total of 11 landing points, including sites in Australia, New Zealand, and Fiji; as well as Hawaii, California, and Oregon in the U.S.

“Even though 90% of capacity on the Southern Cross Cable Network is configured for automatic protection on self-healing rings, there is always a small chance of multiple failures that require redirection of traffic to maintain service,"? said Fiona Beck, Southern Cross CEO. “Until now this has been a manual intervention that would take time to implement. Because service availability is our top priority, we wanted to take advantage of photonic switching technology to eliminate delays when restoring traffic."

CALIENT’s FiberConnect 320X is based on the company’s patented 3D MEMS technology and uses a three-dimensional array of silicon micro mirrors to switch light paths. It offers 640 total fiber terminations consisting of 320 transmit ports and 320 receive ports. The FiberConnect 320X is built with high reliability and redundancy for mission-critical carrier applications. The power supplies and all key electronics cards are hot swappable to eliminate a single point of failure.
