Why TWDM is Superior to XG-PON1

By: Paula Bernier, TMC Executive Editor

Fiber-to-the-home networks service more than 130 households today, and PON is the dominant FTTH architecture. This trend is expected to continue, with 90 percent of the forecast 300 million FTTH subscribers by 2019 to be served by PON, according to Ovum.

As PON subscriber numbers grow, so will the types of users it can address. And that will include enterprise customers. That said, TWDM is the best and obvious way forward for service providers in the GPON realm, according to Ana Pesovic, senior marketing for wireline networks at Alcatel-Lucent who in a recent TechZine posting, TWDM technology moves ahead: XG-PON1, explains why TWDM is superior to XG-PON1 on a number of fronts. These include from a bandwidth perspective, in terms of revenue potential, and in its ability to lower carrier risk.

Ovum backs up those statements in its recent article TWDM-PON is on the horizon: Facilitating fast FTTx network monetization, in which the firm suggests that communications services providers would do well to leapfrog XG-PON1 and move on to TWDM-PON.

Large Enterprises: Think Like a Service Provider When it Comes to Network Connectivity

By: Mae Kowalke, TMCnet Contributor

There is hardly a business today that does not require high speed and high performance Internet connectivity. Let’s face it, quality network access is table stakes for running a successful business in an increasingly connected world where commerce is 24/7/365 and can originate or terminate from anywhere and over any device with a browser.  As a result, ensuring good networking and communications for employees is a major priority for all businesses, but it is an especially daunting one for large enterprises due the volume and the accommodation of rapid change thanks to things like the cloud, BYOD, mobility and the virtualization of the workplace.

A recent Alcatel-Lucent application note, The large enterprise has changed, gave an interesting snapshot of large enterprise IT today.

Details on New Zealand's Ultra-Broadband Effort

By Paula Bernier, TMC Executive Editor

New Zealand is a remote place, which may explain why most people know little more about it than that it served as the backdrop for the Lord of the Rings movies.

The now-concluded HBO series Flight of the Concords also had a lot of references to New Zealand, but it could be tough to discern which ones were real (I checked, and it seems there actually is a toothbrush fence) and which were created for comedy value.

In any case, there’s now a real and important effort going on in New Zealand that involves the creation of a nationwide ultra-broadband network. That state-of-the-art network will help New Zealand’s citizenry and businesses communicate with one another and the rest of the world, and to access existing and next generation information and applications. It’s also intended to make New Zealand a more important player on the world economic stage and to give the country a competitive edge over others in attracting business.

Optical Network Terminal (ONT) Provisioning Made Simple

By: Mae Kowalke, TMCnet Contributor

Fiber-to-the-home (FTTH) enables providers to deliver more bandwidth and better services to customers, but service provisioning can be a substantial headache since FTTH networks are shared and therefore the optical network terminal (ONT) location is not known. Not knowing the ONT location, currently operators must send a technician to the customer’s home to establish the right location and apply service provisioning.

Alcatel-Lucent understands this problem well, and it has taken steps to ease the pain of FTTH service provisioning by developing its ONT Easy Start solution.

Quantifying IP/optical integration synergies

  • Mohcene Mezhoudi, Senior Consultant Member of Technical Staff in the Bell Labs Consulting Services department
  • Arnold Jansen, Senior Product Marketing Manager

From original Alcatel-Lucent TechZine posting

IP/optical integration typically results in cost savings, but maintaining service availability is also essential when measuring total return on investment (ROI). An analysis of 3 modes of operation found multi-layer protection and restoration to be the most cost efficient while meeting availability requirements.

On the Road to IP and Optics Convergence

By: Peter Bernstein, Senior Editor

For what seems like ages now the communications industry has been talking about convergence. We have already gone through many phases as networks move from TDM to being end-to-end Internet Protocol (IP) with voice traffic increasingly being carried on converged networks.  Indeed, the popularity of Voice-over-IP (VoIP) and the coming of Voice-over-LTE (VoLTE) on mobile networks is the future.  

That said, convergence is not just about IP but is also about the transformation of global network infrastructures in the wired world, with legs into the wireless one as well, of IP and Optics.  And, as Steve Vogelsang, VP Strategy and CTO, IP Routing and Transport Business Division, Alcatel-Lucent noted in a recent TechZine blog, IP and optics: Time to make nice, “Let’s face it. The future of the communications industry requires a convergence of IP and optics. So maybe it’s time to give each other some overdue respect."

The Need for Smart Cities is Obvious

By: Mae Kowalke, TMCnet Contributor

It goes without saying anymore that people and businesses in an increasingly connected world rely on the Internet for personal and commercial communication. We are also in the midst of a continuing migration of people are increasingly moving to cities as the world is becoming more urbanized.  What has also become clear is that cities with a smart grid and a solid IP infrastructure thrive more than cities that do not. The case for the smart city has never been stronger.

The Evolution of Cable MSOs Must Continue

By: Mae Kowallke, TMCnet Contributor

Triple play was a good start. But Cable multiple-system operators (MSOs) must continue their evolution.

Cable MSOs have been leading the residential entertainment and communication services segment for years. The expansion of their service offerings from broadcast video to video-on-demand, high-speed Internet and voice has enabled MSOs to expand their market share in the face of changing technology and viewing preferences. But to stay competitive, cable MSOs cannot rest on their laurels.

The explosion of connected devices, competition building Gigabit networks over fiber, the expansion of over-the-top applications such as Skype and the evolution of higher quality video such as 4K resolution are demanding that cable MSOs continue to beef up their access networks.

Columbian Broadband Provider Brings 100G Rollout in Time for World Cup Action

By Mae Kowalke, TMCnet Contributor

Anyone who knows “futbol” (aka “soccer” in the U.S. and “football” elsewhere) knows how enormously popular it is in Latin America.  Hence, being able to provide as many fans as possible great inside and particularly remote from stadium user experiences has become something of an obsession.  Illustrative of this is that thanks to its newly installed 100G ultra-broadband network, Colombia’s mobile provider, UNE, was able to debut widespread streaming video services in time for the recent 2014 FIFA World Cup. This meant its subscribers could have quality viewing experiences over their   smart TVs, tablets and smartphones.

Optical Transport Networks Help Operators Meet Growing Traffic Requirements

By: Mae Kowalke, TMCnet Contributor

It has been called the “data storm;” due to increased online video usage, the cloud, and mobile devices, bandwidth demand is increasing relentlessly, and operators are straining to keep up.

Research from Bell Labs suggests that from 2013 to 2017, operators will see a 550 percent increase in bandwidth demand due to the shift to cloud and a 720 percent increase in bandwidth to support IP video across fixed and mobile networks. This will result in a 320 percent increase in the amount of traffic in the core network.

“Telecom operators are starting to realize that simply increasing the line rate is no longer sufficient to control the costs associated with increasing bandwidth demands,” noted David Stokes of Alcatel-Lucent in a recent TechZine article, Optical transport networks and bandwidth demand. In fact, we really are seeing exponential traffic growth as recent research from Bell Labs below shows expected traffic growth from 2013 to 2017.
