Alcatel-Lucent Announces New TWDM-PON Solution

AMSTERDAM — Alcatel-Lucent announced its new TWDM-PON (Time and Wavelength Division Multiplexed Passive Optical Networks) solution. This new fixed ultra-broadband access technology will allow operators to smoothly increase the capacity of existing fiber networks and meet all customers’ growing data demands.

Alcatel-Lucent and Vodafone have been engaged in co-development of TWDM-PON since 2010 to test potential deployment scenarios for the technology. During this time the companies have contributed to its standardization and completed a successful trial.

TWDM-PON Technology to Succeed Current GPON
TWDM-PON technology has been selected as the successor to current GPON technologies. TWDM-PON uses four wavelengths per fiber, giving a total capacity of 40 Gbps, and can support new operational and business uses that create a much faster and higher return on investment for operators than previous generations of PON technology.

Key facts

  • TWDM-PON enables an operator to deliver different services over each wavelength. For example residential, business and mobile backhaul services can be carried over a single fiber. This reduces costs and increases revenue opportunities as more services can be provided with the same infrastructure.

  • Each fiber can be flexibly configured to enable customer services ranging from a few megabits-per-second up to 10 gigabits-per-second.

  • As TWDM-PON can co-exist with current PON technology, it provides a clear and cost-effective way for operators to evolve their existing fiber access networks.

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

According to Matt Beal of Vodafone Group, “Individuals and businesses are showing an ever increasing demand for access to high speed data and services across mobile and fixed networks. 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.”

Federico Guillén, president of Alcatel-Lucent’s Fixed Networks business said, “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.”
