G.fast Promises a Copper Speed Boost with VDSL2 Vectoring 2.0

By Mae Kowalke, TMCnet Contributor

There was a time when fiber-to the-home was seen as the future of broadband. But all that changed with the introduction of VDSL2 vectoring.

“With a single innovation, the market shifted,” noted Alcatel-Lucent colleagues Paul Spruyt and Dr. Stefaan Vanhastel in a recent blog post, The Numbers are in: Vectoring 2.0 Makes G.fast Faster. “Copper became a valuable commodity again as operators began using their copper assets to deliver fast broadband speeds faster.”

Making that copper even more valuable potentially is the new G.fast standard.

G.fast can increase aggregate bit rates over copper loops shorter than 250 m to fiber speeds of more than 1 Gb/s, the authors explained. It also delivers a cost advantage over deploying fiber directly to the home.

The trouble is that G.fast suffers from crosstalk even more than VDSL2. Tests by Bell Labs on older, unshielded cables in Austria showed that G.fast reached speeds of 500 Mb/s over 100 m when a single line was active, but they fell to a measly 60 MB/s when crosstalk was introduced as a result of a second G.fast line being added.

Achieving Network Optimization, Cost Savings with IP/MPLS Backhaul Solutions from Alcatel-Lucent

By Beecher Tuttle

Delivering high-quality, high-bandwidth business service connectivity at an economical price point is critical for today's service providers, who are being challenged by unremitting competition and ever-increasing subscriber traffic growth.

With this in mind, many forward-thinking operators have turned to Digital Subscriber Link (DSL) and Gigabit Passive Optical Networks (GPON) as access technologies for mobile backhaul (MBH) and business service delivery. These networks have been proven to provide high reliability and availability at a cost-effective price point using IP/MPLS backhaul.

Driving DSL Network Performance Excellence with Motive Network Analyzer

A dramatic rise in the performance required of digital subscriber line (DSL) networks is being caused by consumer adoption of bandwidth-demanding triple-play services. With the support of new real-time voice and high-definition video services, DSL network lines are now operating closer to their physical limits. This is straining copper and fiber capabilities and making them more vulnerable to quality and stability problems in delivering high quality experiences to individual households.  

To meet these challenges, service providers must have the right tools and processes to meet the expectations of customers on DSL networks, while also preventing the escalation of operational expenses (OPEX) in doing so even as migrations to all fiber connections are taking place.

This fall Alcatel-Lucent announced that its Motive Network Analyzer surpassed the 100 customer mark. The big draw for this solution is its ability to enable service providers to identify, diagnose and troubleshoot all DSL problems across fiber and copper that can affect the customers’ experience when leveraging broadband service.

By leveraging technology like Alcatel-Lucent's TPSDA, operators will be able to eliminate the traditional gaps between different devices and different access technologies, unifying all services for their subscribers on a single architecture.

A look at the future: Re-defining the communications partner ecosystem

The services and capabilities that have, until now, served carriers well, are only a part of what subscribers are demanding - they want more services and applications, more access, and more integration with their various access devices and networks.

Competition vs. Collaboration: Strategies for New Revenue Generation

The idea is that working in tandem with other industry experts facilitates more rapid development of products that will be more widely available, more reliable, and more cost effective to develop. In addition, market acceptance is increased due to the collaborative nature of the product(s) - there is less hesitation resulting from the perception of single-vendor bias.

Using Multimedia Content Management Solutions to Drive New Revenue While Increasing QoE

The evolution of networks, content, applications, and devices, combined with user's understanding of the capabilities available to them and their new expectations that result from this enlightenment make it critical for providers to be able to leverage flexible service delivery and management infrastructures.

Speed Introduction of New Intelligent Applications and Time to Revenue

By collaborating closely with third-party developers and content providers - and by allowing them greater access to network resources, including QoS capabilities, network-based storage, and key subscriber and device data - operators will not only create long-lasting relationships with these providers by increasing their networks' value to them, but will also allow intelligent, contextual applications and services to be more efficiently developed and rolled out, lowering all-important time to revenue.

Evolve to a More Stable Business Model and Create New Revenue Opportunities

By embracing a the applications enablement ideal, and a high leverage network, operators will put themselves, and their partners, well on the path to a sustainable, mutually beneficial business model for the next generation communications environment. And ultimately, both will benefit from the ability to combine to deliver new, innovative, and rich set of applications to the user community.

Enhance Network Relevance to Strengthen Customer Relationships

In addition to the network infrastructure, operators have significant resources that can be leveraged to deliver applications and content more efficiently and reliably and, importantly, to the users that need or want them. It is these resources that can be leveraged to extend the value of the network to developers and content providers, increasing the ability to generate recurring revenue.
