GigaWaM project concludes, successfully tests WM-PON system
At the end of September 2012, the European-funded FP7 project “GigaWaM” reached a successful conclusion, participants say. The consortium of nine project partners asserts the results lay the foundation for the next generation of FTTx networks by successfully proving concepts and design for all the critical junction points of a WDM-PON.The technology developed under this program enables a protocol-independent, multichannel, high-speed, DWDM-based access network to be realized at a very attractive cost-performance level, satisfying the ever increasing demand for higher bandwidth for quite some time to come, the members add.The project objective was to develop components and packaging technologies for the next-generation high-speed access network. The principle challenge was that the cost of data transmission via wavelength-multiplexing architectures is dominated by the cost of packaging. The project aimed to develop a system with an integration scale approximately 100X higher than the current state of the art, which can be implemented as a seamless upgrade to existing passive optical network (PON) infrastructures without requiring changes or re-routing of optical fibers.The key technical objectives of the GigaWaM project were to implement 64 channels of 50-GHz channel spacing, delivering 1.25-Gbps symmetric bandwidth per wavelength across a distance of 20 km on a single fiber. All key objectives had been achieved, the partners declare.The project, launched in 2008, saw Sweden’s Syntune AB (which was acquired by Ignis during the program, and then sold to Finisar as part of a larger deal) develop a tunable C-Band laser for operation between 50° and 70°C for subscriber units, Vertilas GmbH of Germany develop L-Band vertical-cavity surface-emitting laser (VCSEL) arrays for central office transmitters, and Ignis Photonyx AS in Denmark (also acquired by Finisar) develop the passive optical components such as a flat-top arrayed waveguide grating (AWG) for central office use, an athermal AWG for the remote node, L/C-Band filters, and integration platforms. The hybridization of the optical components was undertaken by Aifotec AG (also in Germany).To achieve the aggressive cost targets, innovative packaging techniques and features have were developed to reduce component count and keep the number of precision alignment steps to a minimum. Additionally the optical engine hybridization concept developed has been optimized for automatic assembly.The final tests at the Technical University of Denmark’s Department of Photonics Engineering, DTU/Fotonik, demonstrated the optical power loss of only 20 dB over a 20-km distance, providing a comfortable margin in the overall power budget. Despite the narrow channel spacing, no interference between channels was seen. The system was shown to scale to at least 2.5 Gbps, limited by receiver sensitivity only.An automatic laser tuning system has also been developed using the remote node AWG as the wavelength reference for each channel. This approach ensures optimal performance for the lifetime of a GigaWaM access network, according to the project partners.The project was coordinated by Nor-Tek, a subsidiary of Pera Technology Ltd (UK).

Fiber in Europe bucks economic trends
As the industry gears up for the FTTH Council Europe’s 2013 conference in London February 19-21, Lightwave European Correspondent Kurt Ruderman asked fiber-optics analyst Richard Mack of CRU International to evaluate the European scene in 2012 and to discuss his outlook for fiber and cable in 2013, particularly as it relates to FTTx in Europe.Lightwave: What were the key developments that shaped the European fiber-optics market in 2012?Mack: Even though several important economies in Europe were struggling with recession, the region’s optical fiber and cable industry fared reasonably well in 2012 – better than in 2009, when the recession had a greater effect on telecom capital spending.For one thing, the large fiber and cable firms have broad-based businesses. That is, they have sales organizations in other regions, and in many cases there are subsidiary or joint-venture factories in other regions. Exports of optical cable by Europe’s factories were higher in 2012 than in 2011.One development in 2012 was that we saw the effects of consolidation. It was first full year of the new Prysmian Group, which combines Prysmian and Draka. The group’s new product and marketing campaigns highlighted the combined product family for telecom, including FTTx applications.Tyco and ADC, which merged about the same time as Prysmian and Draka, progressed with the consolidation of their strengths in interconnect and passive hardware.There were important developments in the optical cable industry’s product portfolio, especially innovation aimed at FTTx applications. This has been a key segment in terms of market growth, and the manufacturers have addressed new opportunities with new cable designs and features aimed at making the cable easier to install.In the fiber industry, bend-insensitive fiber has become well established for cables to be installed in MDU buildings for FTTH. There are several new cable concepts for simplifying the installation of fibers inside buildings -- ways to attach the cable to walls, ways to enter the cables and break out fibers for each floor of a building, etc. ITU standard G.657.A2 fiber has become well accepted for inside-building applications, and ITU G.657.A1 is being widely used in outside-plant applications.Another important driver for fiber came from continued growth in 4G mobile usage, which requires more backhaul and backbone capacity, as well as fiber-optic systems for cell towers, including pre-terminated cable systems, and hybrid power-and-optical cables for linking the radio heads.On the technology side, there was also impressive progress with 100-Gbps transmission systems. Equipment manufacturers, such as Alcatel-Lucent, Ciena, Huawei, Infinera, NSN, and others, announced 100-Gbps system deployments on both terrestrial and undersea cable routes. In both markets, the systems have been used to upgrade the capacity of previously installed fiber-optic cable, not only new fiber.Lightwave: Why was 2012 a reasonably good year in fiber compared with the region’s economic condition?Mack: We would not say that the fiber business is entirely immune to the poor health of Europe’s economy (GDP growth, etc.), but we would point out that fiber is also driven by other factors that are far more positive than GDP trends – bandwidth growth, the EU’s drive for broadband connectivity (the EU Digital Agenda), efficiencies in data transport for rail, utility, and other infrastructure, etc. One good example is Spain, which is among the European markets with weakest GDP growth, and where the incumbent, Telefonica, went ahead with plans to deploy FTTH in Barcelona and Madrid to improve its infrastructure, boost revenues for broadband services, and to improve its operating expenses.Lightwave: How did 2012 compare to 2011?Mack: The amount of cabled fiber (multimode and singlemode) installed in Western Europe rose 5% from 2011 to 2012. This was far better than the negative growth in GDP. The amount installed in Eastern Europe dropped from 2011 to 2012 by 3%, due to a downturn in Russia’s demand. The amount of cabled fiber installed in the Eastern European markets excluding Russia showed an increase of 15%. In addition to the increased quantity of cable, 2012 saw progress in a wide range of application environments, requiring a diverse array of fiber and cable types for FTTH, FTTB, blown installation, etc. This drove R&D into new small-diameter cable types, easily installed cables, etc.Lightwave: What were the big European projects in 2012?Mack: Even though Russia’s demand was down, the FTTH projects underway in Moscow and other Russian cities were still big projects, using a lot of fiber. Russia’s demand was still more than 6 million fiber-km in 2012, even though Russia’s demand in 2012 was down more than 10% from 2011, which was a very strong year in Russia.We also saw progress in FTTx deployments in several important markets. Last year in Turkey, both Turkcell Superonline and Turk Telecom were installing FTTH systems. In the Netherlands, KPN is progressing city-by-city with its FTTH programs at a healthy pace. Ukrtelecom has FTTH projects in Ukraine. In the UK, BT Openreach, which mainly is installing FTTN and using FTTH for a small percentage of premises passed, is ahead of schedule with its multi-year program.Lightwave: What are the top European fiber markets?Mack: In terms of the amount of cabled-fiber (in fiber-km) installed, the top 10 markets in order of size are Russia, Germany, France, the UK, Turkey, Spain, the Netherlands, Italy, Switzerland, and Ukraine. These 10 accounted for 74% of all fiber installed in Western and Eastern Europe. (In this segmentation, Eastern Europe includes all of the former Soviet republics.)Lightwave: What are the big drivers for fiber?Mack: The main driver is broadband service for residential customers and small-and medium enterprise premises. Simply put, fiber lets the service provider offer faster Internet service. For residential customers in some countries, IPTV is an important component of the broadband-services menu. Fiber also lets the service providers gain some operational benefits.Broadband services over FTTx networks have been the main driver for fiber optics in Europe for several years now. It is also the same driver in much of Asia, North America, and parts of Latin America, and Australasia. In India, Africa, and other parts of Latin America, backbone routes are a more significant driver. In China, mobile infrastructure has been the biggest driver (accounting for the most fiber and the most growth in recent years), although FTTH is also a major factor in the China market.Lightwave: What were the big obstacles to fiber deployment in Europe in 2012?Mack: Generally, the obstacles for fiber deployments have to do with cost, competition, and government policies. The cost problem is that VDSL can meet the EU Digital Agenda targets in many locations, and it gives a conservative carrier a safe way to offer broadband with less risk of stranded investment or having to share fiber infrastructure. When the new vectoring technology and the somewhat older pair-bonding technologies are used with VDSL, the bit rates can meet the Digital Agenda targets. In some countries, there is also a competitive CATV-industry offer for broadband, based on DOCSIS technology.In France, for example, Iliad-Free cut back its FTTH deployments, possibly due to a new focus on mobile in 2012. SFR’s demand was down a little, and Orange (FT) was flat. The complex regulations imposed by ARCEP in recent years may have contributed to the slower progress, as the carriers are required to explore joint investment or mechanisms for sharing infrastructure, depending on whether the deployments are in one of several types of “zone” or regions of population density.Lightwave: What is the outlook for 2013?Mack: The main observation about the European market is that it is a highly diverse group of about 50 countries. There are some small markets, such as Andorra, Iceland, and Jersey, that have been aggressive with FTTH. There are some large markets, such as Germany and UK, that have been conservative with FTTH, and more willing to pursue FTTN and “partial-fiber” access network architectures. The largest market, Russia, has been aggressive with FTTB, and recently with FTTH, and this has made it the largest market in Europe -- more than twice the cabled fiber installed per year as the next largest in recent years.In 2012, there were some signs for stronger commitment to spending on fiber in 2013 among key carriers in Germany, Italy, and Spain. With progress in these markets, along with a resumption of growth in Russia, and steady progress in other markets such as Turkey, Netherlands, Switzerland, and France, there is the potential for an increase of 5% to 10% in the amount of cable installed.
