Partners in the TransportPCE project, including Orange and AT&T, demonstrated using open source code to simplify and accelerate the use of interoperable optical transponders during this week's NGON & DCI 2018 in Nice.
Initiated by Orange in 2016, TransportPCE is an OpenDaylight application that offers tools to make it easier to deploy multi-layer transport use cases with OpenDaylight. Its goal was to build an open optical transport infrastructure controller, according to the French service provider. (See Orange, Telia Initiate TransportPCE Project in OpenDaylight.)
The team of operators and vendors opted to focus on controlling optical equipment that complies with OpenROADM Multi-Service Agreement (MSA), defining common models for devices, networks, services and some optical specifications.
Timing is critical: The impending arrival of 5G and the huge surge in anticipated traffic, coupled with the telecommunications industry's increasing adoption of open source, standards and interoperability, are driving changes in optical transport networks. Operators want to reduce operational complexity so they can expand automation and cut costs.
During NGON & DCI 2018 this week, Orange and AT&T demonstrated several interoperability use cases using TransportPCE software code to configure an end-to-end path crossing network elements from different suppliers on a Proof of Concept (PoC) Platform in Orange Labs. This showed the level of interoperability introduced by the OpenROADM initiative, according to Orange.
The uses cases tested, mixed transponders and ROADM from Ciena and Fujitsu in multiple configurations. Testing achieved Interoperability between Ekinops transponders implementing proprietary high Soft Decision FEC and Ciena/Fujitsu OpenROADM infrastructure, following an Open Line System (OLS) approach, Orange reported.
The PoC also showed OpenROADM equipment can be built by using specific software (Fujitsu) or firmware (Ciena) in the equipment or by using a gateway to interconnect with legacy equipment and make them compliant with OpenROADM (Ekinops). In this way, operators can predict the path toward future network programmability in a brownfield environment, upgrading pre-deployed equipment to make them compliant with the latest open standards, said Christian Gacon, vice president of Wireline Networks and Infrastructure at Orange, in a statement.
"Thanks to the contributions of AT&T, Orange and others to this project, TransportPCE now provides software code for reference implementation that will facilitate the evolution towards openness and interoperability in optical transport networks," said Gacon added.
Noted John Paggi, AT&T's assistant vice president and member of technical staff: "The work in TransportPCE has been instrumental in developing a true model-based controller using the OpenROADM MSA device, network and service models, allowing us to move to a single shared solution and drive new features faster."
Beaver Creek Cooperative Telephone Co. needs to replace its legacy system with a future-proof solution that integrated with its enterprise Ethernet offering, had available professional services – but did not break the bank.
Nokia kicks off a busy October by announcing a fixed access network slicing solution, PON interoperability approach and antennas that make a sound business case for 4G fixed wireless residential service.
With the availability of SD-Access products that leverage Amendment 3 Gfast capabilities like 212 MHz spectrum, DTA support and ability to deliver symmetric gigabit speeds, operators can quickly sate the needs of gigabit-hungry customers.
Telefónica Deutschland will use Deutsche Telekom's fiber-optic cable network to connect at least 5,000 mobile base stations to support 3G and LTE networks and prepare for 5G; to accelerate rollouts, DT will use artificial intelligence on some future fiber deployments.
With its recently opened South Atlantic Cable System (SACS), Angola Cables CEO António Nunes realized a personal goal — and connected Angola to North and South America, along with a world of new opportunities for the telco wholesaler and the continent it calls home.
Fast, reliable broadband is essential to how we live, work and play today – and the upcoming arrival of 5G will only further increase demand and reliance on fiber infrastructure. Already viewed by consumers as intolerable, delays, outages or the regular maintenance difficulties associated with operating a network will become further exacerbated when residential subscribers further rely on connected devices for day-to-day life. Just as providers deploy network automation tools to reduce operational issues, they must take similar care to manage consumer expectations when they roll out fiber or new services. This webinar features leaders who will discuss how to manage marketing and consumer expectations at every stage of the network lifecycle. Marketing professionals, c-level executives and policymakers interested in drumming up fiber envy should attend.
In this insightful Light Reading radio show, Kurt Raaflaub, Head of Strategic Solutions Marketing, will outline the key service provider challenges, deployment considerations, next-gen Gigabit technologies, and service models to win market share in the rapidly growing MDU market.
