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.
