du Tests Nokia's 40 Gbps TWDM PON

Nokia has supplied its Time and Wavelength Division Multiplexing Passive Optical Network (TWDM-PON) technology to UAE-based telecommunications service provider du for testing in its lab.  The PON solution is capable of aggregate speeds of 40 Gbps.

Nokia said its unique next-generation Passive Optical Network solution will enable du to upgrade its existing GPON network to XGS-PON or TWDM-PON on a single fiber.

Jasim AlAwadi, Vice President - Network Infrastructure & Services, at du, comments: "With the increased use of smart devices and bandwidth-hungry applications by our subscribers, the demand for an ultra-fast network also keeps increasing. Keeping our customers on the top of our mind, we pioneer by introducing market-leading technologies to them. Our successful test of Nokia's TWDM-PON is proof of this. We are confident that our cooperation will take the country's journey toward IoT and smart cities to the next level."

Rima Manna, head of the du customer team at Nokia, says: "With its current strategy, du is very well positioned to evolve its network now and in the long term, and meet the customer needs of one of the leading broadband countries in the world. With this latest successful test, we reiterate our commitment to du in its endeavor to launch truly innovative services for its subscribers across the country."

Alcatel-Lucent Intros 10G TWDM-PON

Alcatel-Lucent is looking to bring down the cost of TWDM-PON (Time and Wavelength Division Multiplexed Passive Optical Networks) by allowing different types of optics to be used.  Currently, TWDM-PON requires new optics capable of providing four tunable 10 Gbps wavelengths.

Alcatel-Lucent's new ‘Universal TWDM’ solution enables operators to initially deploy one non-tunable 10 Gbps wavelength and easily add more pluggable as demand grows, providing a smooth upgrade to full TWDM without the need to replace network components, evaluate new technology, or reconfigure operations and business support systems (OSS/BSS).

"The primary obstacle for deploying new ultra-broadband infrastructure and services is the business case. Universal TWDM is Alcatel-Lucent’s innovative solution to this challenge. We are enabling operators to build upon their existing fiber investments while bringing down the total cost of ownership of TWDM technology. This means they can immediately address new high-revenue opportunities for gigabit services while knowing that their investment is future-proof,” stated Federico Guillén, president of Alcatel-Lucent’s Fixed Access Business Line.

The company noted that Universal TWDM and full TWDM-PON can co-exist with current PON technology. Alcaltel-Lucent also estimates that Universal TWDM will have a similar cost as established 10 Gbps technologies, such as XG-PON.

Chattanooga Offers 10G Residential Service for $299 a Month

EPB, the municipal utility of the City of Chattanooga, Tennessee, has launched the first 10G residential Internet service across a large community-wide territory.

EPB’s 10 Gig service, which is now available for access by every home and business in a 600 square mile area, uses Alcatel-Lucent’s TWDM-PON broadband technology. The service is priced at $299 per month. EPB is also launching 5 Gig and 10 Gig Internet products for small businesses as well as a 3 Gig, 5 Gig and 10 Gig “Professional” products for larger enterprises. These Internet services are available at varying price points.

“Five years ago, Chattanooga and Hamilton County became the first in the United States to offer up to 1 Gig Internet speeds,” said Harold DePriest, president and CEO of EPB. “Today, we become the first community in the world capable of delivering up to 10 Gigs to all 170,000 households and businesses in our service area.”

“Alcatel-Lucent is a strong proponent of the benefits of ultra-broadband technology for economic development,” said Danny Rollins, Vice President, Alcatel-Lucent Global Enterprise & Public Sector Sales for North America. “As a long-term supplier for EPB’s gigabit networks, we’re proud to be helping EPB and the city of Chattanooga be at the forefront of the ultra broadband movement and provide the industry’s leading fiber technology to help deliver on many services and innovation it brings to the community residents and businesses.”

  • EPB is one of the largest publicly-owned electric power distributors in the U.S., serving more than 170,000 homes and businesses in an area that includes greater Chattanooga and Hamilton County, as well as portions of surrounding Tennessee counties and areas of North Georgia.
  • In September 2010, EPB became the first company in the United States to offer community-wide one gigabit-per-second Internet speed, a critical component of next generation technology innovation and economic development, to every home and business in its 600-square mile service territory.

NTT and Oki Develop 40 Gbps WDM/TDM-PON

NTT nd Oki Electric Industry Co. have jointly developed a WDM/TDM-PON technology capable of transmission at 40 Gbps over a 40km distance while servicing 1,024 users.

The jointly developed WDM/TDM-PON technology consists of (1) wavelength-tunable burst-mode optical transceivers, (2) a wavelength multiplexed burst-mode optical amplifier and (3) a wavelength tuning protocol. Each Optical Network Unit (ONU) on the customer premises communicates at one of four pre-determined wavelengths. Two types of wavelength-tunable burst-mode optical transceiver have been developed in this project. Each wavelength carries 10 Gbps.  A wavelength tuning protocol has been developed that allows for the switching of the ONU’s wavelength to any one of the other three wavelengths at which there is less traffic.

  • In October 2014, Alcatel-Lucent introduced the industry’s first TWDM-PON (Time and Wavelength Division Multiplexed Passive Optical Networks), a new fixed, ultra-broadband access technology for scaling the capacity of existing fiber networks. TWDM-PON uses four wavelengths per fiber, giving a total capacity of 40 Gbps. An operator can choose to deliver different services over each wavelength, enabling residential, business and mobile backhaul services to be carried over a single fiber. TWDM-PON technology is supported by Alcatel-Lucent‘s 7360 Intelligent Services Access Manager FX solution.  The company is introducing a new 4-port TWDM-PON line card and optical network unit supporting 10Gbps symmetrical bitrate. Products will be available in the first quarter of 2015.  Alcatel-Lucent and Vodafone have been co-developing TWDM-PON since 2010 as a potential successor to GPON. During this time, the companies have contributed to its standardization and completed a successful trial. Significantly, TWDM-PON can co-exist with current PON systems.
