NTT Develops Flexible Access System Architecture with Virtualized OLTs

NTT is developing a new Flexible Access System Architecture (FASA) that aims to leverage a new generation of virtualized optical line terminals (OLTs).

NTT said FASA will not make use of conventional purpose-built equipment, but instead modularize the various individual functions of access equipment as much as possible. The idea is to use generic OLT hardware that allows modularized software components to run for specific functions, such as bandwidth control, OAM, multicast, and future services.  NTT is developing an API with multiple industry partners. The first API is schedule for release in May 2016.

With FASA, the components of access equipment are separated into the three types: 1) Software components, 2) Generic hardware, and 3) External modules. FASA enables access equipment to provide its necessary functions through the unrestricted combination of these three component types. With software components (1), it will become possible to add new functions quickly and flexibly just by adding or updating necessary software in response to the requirements of services. For the generic functions of access equipment, generic hardware (2) will make it less frequently necessary to newly develop equipment from the device level by striving to achieve a set of common generic components. The creation of such components can also be expected to lower equipment costs and make maintenance simpler by reducing the number of component types that need maintenance. For functions like optical transmission that are difficult to address with either software components or generic hardware, things like optimal transmission capacities can be achieved through the use of external modules (3) that can be substituted for dedicated hardware in response to the requirements of services.

NTT is also working on a a visualized testing environment.  Its NetroSphere concept will undertake testing of FASA and other key technologies, such as Multi-Service Fabric (MSF), new server architecture (MAGONIA), and Integrated Management.

NTT's NetroSphere Concept Pushes NFV to Next Level

NTT outlined its work developing the “NetroSphere concept” -- a new way build carrier network infrastructure that differs from other NFV approaches by taking the decoupled software/hardware paradigm all the way down to the component level.

NTT said its approach promises enhanced flexibility and elasticity while also drastically reducing costs. Breaking up the functions of conventional large-scale equipment into modules will enable a greater diversity of suppliers to participate in the market and hence widen the selection of available products.

Instead of using conventional purpose-built high-functionality equipment, NetroSphere aims to divide them into small modular components, and flexibly assemble those components at will.  NetroSphere will not limited to decoupling software components from equipment. It pursues modularization as much as possible, ultimately at the sub-device level such as the CPU and memory. These modules will be distributed in locations that are optimal for each type of them, and prepared to be used as resource pool. Then, they will be virtually assembled to form a virtual system to provide required functions.

There are two components to the NetroSpher concept:  (1) Multi-Service Fabric (MSF), an architectural design of carrier network in which functions are achieved using simple general-purpose servers and switches, and (2) New Server Architecture (MAGONIA).

NTT plans to open its work on “MAGONIA” and “Multi-Service Fabric (MSF)” to other carriers and vendors.

Alcatel-Lucent's TWDM-PON Carries Four 10G Wavelengths

Alcatel-Lucent introduced the industry’s first TWDM-PON (Time and Wavelength Division Multiplexed Passive Optical Networks), a new fixed, ultra-broadband access technology for scaling the capacity of existing fiber networks.

TWDM-PON uses four wavelengths per fiber, giving a total capacity of 40 Gbps. An operator can choose to deliver different services over each wavelength, enabling residential, business and mobile backhaul services to be carried over a single fiber.

TWDM-PON technology is supported by Alcatel-Lucent‘s 7360 Intelligent Services Access Manager FX solution.  The company is introducing a new 4-port TWDM-PON line card and optical network unit supporting 10Gbps symmetrical bitrate. Products will be available in the first quarter of 2015.

Alcatel-Lucent and Vodafone have been co-developing TWDM-PON since 2010 as a potential successor to GPON. During this time, the companies have contributed to its standardization and completed a successful trial. Significantly, TWDM-PON can co-exist with current PON systems.

Alcatel-Lucent said TWDM-PON also enables a ‘pay as you grow’ model, allowing operators to easily and cost effectively increase bandwidth as required. Wavelength multiplexing means different operators can easily share the same infrastructure. This can facilitate competition (for example, a municipal-owned network can be leased to different service providers) or cooperation (operators can co-invest in a shared fiber network in order to accelerate ultra-broadband deployments).

“TWDM-PON is ground-breaking technology that will give us greater control over network capacity and increased flexibility when provisioning new services. We have worked closely with Alcatel Lucent to develop the technology and we look forward to evaluating it on our network in Spain,” stated Matt Beal of Vodafone Group.

Federico Guillén, President of Alcatel-Lucent’s Fixed Networks business: “For the last four years Alcatel-Lucent and Vodafone have been working closely together to evolve PON technology. Our first TWDM-PON solution reflects that collaboration. Alcatel-Lucent is committed to a program of innovation; we have long been the technology leader in both copper and fiber fixed access technologies and we are extending this further with this new development of PON. Vodafone has played a vital role in preparing TWDM-PON as an industry-agreed standard by looking at its own potential usage in different countries for both fixed and mobile operations.”

Alcatel-Lucent’s in 12 Carrier Trials

Alcatel-Lucent 's ultra-broadband solution is now in trials with a dozen carriers around the world and is exptected to become available in the first quarter of 2015.  Announced test sites include A1, a subsidiary of Telekom Austria, in which a regular subscriber was connected in order to independently test in the field. Other trials have included BT and Orange.

Alcatel-Lucent said its new 7368 ISAM single-port Optical Network Terminal (ONT) can deliver speeds of up to 1 Gbps over existing telephone lines. Alcatel-Lucent’s ONT can also be deployed in a multiple-dwelling unit, with one ONT serving each household. Customer trials use a multi-port solution using vectoring technology to eliminate the cross-talk interference that occurs when two or more copper lines are in close proximity, which adversely affects speeds. The multi-port solution will drive the evolution of Alcatel-Lucent’s VDSL2 micro-node portfolio.

The company also noted a recent Bell Labs demonstration of XG-FAST technology, which achieved symmetrical speeds of 1 Gbps over 70 meters of copper in the lab.

Dell'Oro: VDSL and GPON Drive Strong Q2 Access Market

Total second quarter Access revenue, including PON, DSL, and Cable, surged 12% over the year-ago period, according to a new report from Dell'Oro Group.  This growth was driven by a greater than 30% increase in VDSL port shipments and more than 40% increase for both GPON OLT port and ONT unit shipments.  The report shows that year-on-year growth was driven by higher shipments across all regions for both technologies.

“EMEA and North America accounted for the vast majority of VDSL shipments with Western Europe being especially strong as an increasing number of operators deploy vectoring products, which can significantly increase bandwidth while using existing copper infrastructure,” said Steve Nozik, Principal Analyst of Access research at Dell’Oro Group.  “For GPON, China continues to dominate the market but there was also significant growth in other regions especially Southeast Asia, Southern Europe and the Middle East,” Nozik added.

The report shows that in the second quarter, Alcatel-Lucent continued to hold the lead for VDSL port shipments, significantly ahead of the next two top vendors, Huawei Technologies and ADTRAN.  For GPON, Huawei Technologies and ZTE were the top two vendors due largely to their market leadership position in China, followed by Alcatel-Lucent in the number three position.

ITU: Broadband Remain Unaffordable in Many Markets

While there are some 600 million broadband lines in service worldwide, affordability remains a major obstacle, particularly in Africa, where fixed broadband access costs on average three times monthly per capita income, according to the ITU's newly published "Trends in Telecommunication Reform" annual report.

In contrast, mobile cellular and mobile broadband services remains very competitive in 92 percent of all markets. By the end of 2011, ITU estimated that the number of mobile-cellular subscriptions reached close to 6 billion, representing a global penetration of 86.7 percent and a penetration level of 78.8 percent in developing countries.

Subtitled ‘Smart Regulation for a Broadband World', this year's report sheds light on the often complex legal and regulatory issues now emerging as broadband becomes pervasive and increasingly serves as a driving force for the development of other economic sectors. Case studies and decision trees are provided for national regulators who are working through the process of developing a broadband plan for their country. Ultimately, there is not a single "right" universal service funding model, according to the report, but there are common principles such as economic efficiency, equity, competitive neutrality, technological neutrality, certainty, transparency, and cost effectiveness.
