  • 100G Brings A New World of Testing Challenges
    Vikas Arora, Chief Technology Officer, EXFO; François Robitaille, Senior Product Line Manager, Optical Business Unit, EXFO; Patrick Drolet, Product Line Manager, Transport and Datacom Business Unit, EXFO
    2009-10-01
An overview of the evolution in bandwidth and the promising 100G technologies that are leading the way, as well as an examination of the new paradigm of testing challenges created—both in the lab and the field.
  • 40/100G Deployment: When to Test
    Francis Audet, Senior Product Manager, Optical Business Unit, EXFO; Karim Fahim, Product Manager, Transport and Datacom Business Unit, EXFO
    2009-10-01
An overview of the best practices for when to test at 40/100G; namely, verifying if the link has physical impairments, validating the ROADMs in the system and ensuring end-to-end connectivity and performance for the different services.
An overview of four 40G market drivers, two major components in any 40G network—ROADMs and OTN—and EXFO’s solutions for 40G fiber characterization, link commissioning and upgrade as well as wavelength services turn-up.
A summary of the main challenges of 40 gigabits transmission networks, such as polarization mode dispersion, chromatic dispersion and optical signal-to-noise ratio measurements, particularly in a mesh network and brief presentation of solutions to overcome those challenges.
An insight in advanced modulation schemes as a new technology trend in fiber optics, with the increase in bandwidth demand, and the impact of such technology on test and measurement requirements
An examination of the value of analytics and reporting tools to provide comprehensive information across the organization, such as differentiating between services based on more than just speed or price and comparing the service quality and usage across peak days and hours.
An overview of assessing Ethernet-based business services from turn-up testing to baselining, troubleshooting, monitoring and SLA conformance, including issues such as multiservices, migration to packet-based, support for legacy TDM-based services over packet architecture, as well as the lack of access to high-bandwidth.
An overview of the best practices that network service providers should adopt to minimize their investment risks, decrease time to market with new services, increase average revenue per user (ARPU) and reduce customer churn.
An overview of the main benefits and drawbacks of complex modulation schemes systems, as well as the advantages of using optical sampling, one of which being the elimination of distortion, often present in complex modulated signals.
An overview of the challenges that network equipment manufacturers (NEMs) developing IMS network elements and network service providers (NSPs) deploying IMS networks need to face, as well as a look at the test that they should perform to validate that the networks operates as it should.
EXFO is the first to implement EtherSAM, an Ethernet service testing methodology based on the ITU-T Y.156sam standard. This new methodology is the only one fully adapted to today’s mobile backhaul, commercial and wholesale services. It allows turning up and troubleshooting services eight times faster with 100% accuracy.
An overview of the use of FTTH from Greenfields to multidwelling units and the challenges, including the triple-play race for bandwidth and FTTH as the end-game, as well as a look into the best ways to test to reduce OPEX.
An overview of how mobile operators who are switching to Ethernet circuits monitor those circuits 24/7 365 days to and assure they are getting good high quality service from their backhaul providers.
An overview of the three trends observed in the industry: the convergence and protection of the bundle, the management of services based on network quality versus on service quality (TCP/IP) and the service lifecycle—from the lab to installation and operational monitoring.
An overview of the challenges that service providers must face when migrating to wireless backhaul infrastructure, as well as the efforts currently underway to synchronize networks via packet synchronization.
An overview of how to gain full IP network visibility without additional cost or dependence on one vendor, as well as an examination into how the intelligence of IP infrastructure can be leveraged for service assurance.
A presentation of the main differences between electrical sampling—the more traditional approach—and optical sampling; also an insight into the benefits of using optical sampling, which is not bandwidth-limited and provides a detailed waveform analysis.
An overview of the importance of standards and leveraging in user equipment for end-point reporting, which validates installation, technician accuracy and efficiency and also provides troubleshooting access and proactive monitoring for visibility.
An overview of the RGUs, quad-play and assuring the bundle, as well as finding a way to correlate information across the bundled services and the importance of understanding the interaction of traffic is key to the success of a multiservice operator.
A demonstration of the in-band optical signal-to-noise ratio (OSNR) measurement using an optical spectrum analyzer (OSA) when validating reconfigurable optical add/drop multiplexers (ROADMs).
An overview of the security issues that service provides need to consider for their VoIP and IMS networks in order to prevent their networks from coming under attack, thereby avoiding service degradation as well as reducing customer churn.
An overview of the challenges found at service turn-up, including the validation of network configuration and performance, the testing architecture (end-to-end vs. round-trip), as well as the repeatability of the test methodology.
A brief overview of the key challenges that service providers will face when deploying VDSL2 equipment and services, including effects on the ‘last mile’, as well as an examination of what providers need to know to offer consistent services.
A description of the IPTV application, the challenges of its delivery and the need for a multidimensional analysis framework from the core to the door. Plus, a brief overview of EXFO’s fully integrated solutions for the entire lifecycle.
An overview of one of the key challenges that comes with the migration of mobile backhaul to a packet-based network: testing and monitoring performance. As well as a look into how carriers can ensure end-to-end service quality assurance to consistently deliver quality services.
An overview of how packet-switched technology presents the most scalable and flexible transport solution to meet the booming bandwidth challenge, as well the influencing factors that are forcing the migration to packet backhaul.
An overview of a new concept: Single-ended wideband testing as well as a look into the quality of service (QoS) realities that providers frequently face. Plus, at look at how being fully equipped for quick turn-up and troubleshooting can make all the difference in avoiding customer churn.
An overview of the market trends that are occurring in service assurance as well as the three major impacts on the architecture and methodology of systems, as well as an examination into the challenges these trends also present.
