Verizon and Calix hit 34 Gbps over fiber using bonded NG-PON2

Verizon and Calix achieved 34 Gbps speeds over fiber using a bonded NG-PON2 (Next-Generation Passive Optical Network 2) ONT (Optical Network Terminal) prototype on Verizon’s simplified, increasingly automated fiber network. The demonstration was conducted at the Verizon Innovation Center in Waltham, Massachusetts.

To reach 34 Gbps, Verizon and Calix bonded all four available wavelength channels.

Verizon said it expects NG-PON2 technology will provide faster speeds, lower latency, simplification of operations and increased automation in the fiber network.  To achieve those benefits, NG-PON2 technology must be deployed throughout the entire fiber network.  Last year, Verizon and Calix successfully trialed NG-PON2 on the OLT (Optical Line Terminal).

“We know how important connectivity is to small and mid-size businesses,” said T.J. Fox, Senior Vice President and President of Verizon Business Markets. “These advances will deliver the promise of the cloud for our customers and bring them technology at parity to what previously was only in reach for large enterprises.”

“The AXOS Intelligent Access Edge simplifies the network, dramatically increases service velocity, and creates the foundation to unify both business and residential services into a single access transport,” said Michel Langlois, chief development officer for Calix. “The latest test results demonstrate how this approach enables CSPs to extend the benefits of AXOS all the way to the subscriber edge. With new services becoming increasingly bandwidth-intensive, our work with Verizon has demonstrated that AXOS systems leveraging NG-PON2 will provide the future-proof connectivity needed to meet these demands.”

Verizon goes all in with One Fiber program, NG-PON2


We are big believers in taking fiber all the way to the customer, said Lee Hicks, Verizon, speaking at ADTRAN's Broadband Business Solutions event in Huntsville, Alabama. Verizon's One Fiber program is its multiyear strategy to build a common fiber plant for all services, including consumer, business and mobile backhaul. The carrier starts with a deep base fiber, having invested in its FiOS FTTH network for years. In April 2017, Verizon awarded...


Verizon has selected Calix's AXOS E9-2 Intelligent Edge System to begin large-scale NG-PON2 deployments this quarter. These deployments will include the AXOS RPm (Routing Protocol module for Layer 3) and the AXOS SMm (Subscriber Management module for disaggregated Broadband Network Gateway). Financial terms were not disclosed. Calix said its NG-PON2 converged services platform enables Verizon to deploy a single access network for residential, business,...


ADVA leads PEARLS project to integrate quantum-dot lasers onto ePICs

ADVA is leading a three-year initiative funded by Germany’s Federal Ministry for Education and Research (BMBF) to create advanced optical transceiver chiplets for data center interconnect (DCI) applications.

The project entitled “Photonic Embedding of Active Region Laser chips in Silicon (PEARLS)” aims to integrate quantum-dot lasers onto silicon-based electro-photonic integrated circuits (ePICs). By combining silicon photonics, BiCMOS electronics and lasers on a single chip, the size and cost of optical transceivers can be dramatically reduced. The three-year project involves a consortium comprising ADVA, FormFactor, Fraunhofer IZM, IHP, IHP Solutions, Sicoya, Technion and the University of Kassel.

“With this project we’re taking integration and compact design to new levels. By squeezing more technology onto a single chip than ever before, we’re creating a platform for miniaturized optical transceivers able to deliver the space and bandwidth density needed for tomorrow’s DCI networks,” said Jörg-Peter Elbers, SVP, advanced technology, ADVA. “PEARLS not only paves the way for a new generation of intra-data center transceivers, but also facilitates more compact and cost-effective integrated coherent transmitter-receiver optical sub-assemblies (IC-TROSAs) for inter-data center applications.”

ADVA also noted that the PEARLS project is aiming to take a silicon-based electro-photonic chip platform – which offers monolithic integration of electronics and photonics as already proven in the ADVA-led SPEED project – and extend it to incorporate a third key element: Nanotechnology lasers will be added to the chip, saving space and reducing energy consumption compared to off-chip approaches. This will be achieved with quantum dots just a few nanometers in size. Able to withstand extreme temperatures, they facilitate wafer-scale integration without the need for a thermo-electric cooler or a hermetic package.

“Within this very exciting project, IHP will develop the technology platform. Together we’re breaking new ground and laying the foundations for the next generation of low-energy, space-efficient optical transceivers,” commented Bernd Tillack, managing director, IHP GmbH. “The PEARLS project will pave the way for optical transceiver chiplets – modular transceiver chips with an unprecedented level of optical and electronic integration. Built on top of a standard BiCMOS process flow, the new technology will also be a major step forward for sustainable DCI networking.”

Cisco's NCS 1004 platform tested over MAREA subsea cable

Cisco's NCS 1004 platform was successfully tested over MAREA, the 6,600 km subsea cable system connecting the United States to southern Europe (Virginia Beach, Virginia to Bilbao, Spain).

Several channel capacity combinations were tested to maximize the performance and spectral efficiency on the cable. For the Virginia to Bilbao trial, 400G error-free performance was demonstrated; channels with record spectral efficiency of 6.445 b/s/Hz were achieved, while 4.52b/s/Hz spectral efficiency was tested on the looped back scenario of over 13,200km.

Cisco also said the test simulated transpacific distances via loopback on one end of the cable.

“We demonstrated that 24.7Tbps could be used on MAREA with plenty of margin. We also tested in full loopback mode (Bilbao to Virginia and back to Bilbao) showing that 18.5Tbps could be deployed for double the distance, also with plenty of system margin,” said Bill Gartner, Senior Vice President and General Manager, Optical Systems and Optics, Cisco.

Itential launches API services for network automation

Itential launched new API Services that enable organizations to implement NetDevOps concepts and move toward Network Infrastructure as Code.

Itential said its solution was designed for DevOps and NetOps teams to accelerate the move toward software-driven networks through automation and agile network operations.  NetDevOps allows organizations to adopt CI/CD pipelines with the ability to build, test, validate and deploy changes before they are made to the network.

Itential’s NetOps pipeline capabilities include:

  • Build – Create the building blocks of your infrastructure
  • Dynamically render configurations from a library of expert built templates that combine reusable chunks of configuration to create composite configurations. Transform data from one format into another and run optimizers to eliminate redundant or poorly designed config.
  • Test – Ensure your infrastructure change does what you intend it to do
  • Simulate the change before you make it and compare simulation outputs to known desired outcomes. Check to see if your change affects any pre-existing functionality.
  • Validate – Ensure that your changes are safe
  • Check that a configuration is error free, before you deploy it to a device. Run a security scan to see if you’re running compromised software and run a security scan to see if you’re exposed to network threats.
  • Deploy – Deploy your infrastructure changes to your network
  • Leverage tools like Ansible, Terraform, SDN Controllers, and Orchestrators to push changes to your network. Update operational support systems to stay in sync with your network changes and keep track of your changes by tagging and versioning them when you deploy.


“The complexity of today’s networks, combined with the lack of investment in modern application concepts, has created a situation where network management applications are constraining the ability to support business and consumer demands,” said Chris Wade, CTO, Itential. “By incorporating a Network Infrastructure as Code approach to automation, enterprises can use Itential’s modern agile software development principles to build, test, validate, and deploy network changes and adopt existing investments in the infrastructure as code ecosystem.”

Cignal AI: Compact modular market slows as customers evaluate 600G

Sales of Compact Modular optical transport platforms slowed during the second quarter of the year despite significant growth from market leader Ciena, as reported in the latest Optical Applications Report from market research firm Cignal AI.

Production shipments of new 600Gbps platforms are taking longer to ramp as operators require more time to evaluate these next-generation solutions. As a result, Cignal AI has decreased the overall 2019 Compact Modular sales forecast for the year.

The outlook for Compact Modular equipment remains positive, especially in NA and EMEA where growth is strong as incumbent and cloud & colo operators expand the use of disaggregated networks. Compact modular will claim a greater percentage of the market as operators migrate to IP-over-DWDM in 2022/2023.

“The move to disaggregated networks continues, and Compact Modular optical platforms are a central part of those network designs,” said Scott Wilkinson, Lead Analyst for Optical Hardware and Cignal AI. “The rollout of 600Gbps platforms is taking longer than anticipated, but NEL and Acacia-based systems from Cisco, Infinera, and others should recognize greater revenue in the third quarter and will lead a return to growth.”

Cignal AI’s 2Q19 Optical Applications Report details market share and provides forecasts through 2023 in three key markets: compact modular equipment, advanced packet-OTN switching hardware, and 100G+ coherent WDM port shipments across multiple speeds.



Additional 2Q19 Applications Report Findings:

  • Ciena maintained leadership in the Compact Modular market and was the only vendor to grow sales in Q2. Other vendors are in the middle of a customer transition to higher 400G+ coherent technology.
  • Cisco recognized token revenue from Acacia-based Compact Modular systems this quarter. Both Cisco and Infinera are expected to recognize significant 400Gbps+ revenue in the third quarter.
  • Packet-OTN sales slowed in APAC but this is not an enduring trend; sales growth slowed in Q2 due to some delayed demand among Indian incumbents. This region remains the largest market for Packet-OTN.
  • Almost 500,000 coherent ports shipped during the past twelve months, with the vast majority coming from the top 5 vendors. Volume continues to aggressively ramp during 2019, including healthy shipments from Chinese vendors.
  • The long haul WDM market is growing in 2019 due to deployments of the latest coherent technology. Metro growth continues through the year with a delay in competitive price pressure from high baud rate optics.
