Türk Telecom selects Alcatel-Lucent for VDSL2-based FTTB deployment

Türk Telekom, Turkey's incumbent telco, on Wednesday began deploying Alcatel-Lucent's (NYSE: ALU) Intelligent Services Access Manager (ISAM) Fiber to the Building (FTTB) platform for its next-gen last mile access strategy to deliver higher speed broadband and video services via a hybrid copper/fiber network architecture.

To fulfill the requirements of what it calls the "FiberkenTT" initiative, Turk Telecom will deploy the Franco-American vendor's 7353 ISAM FTTB solution.

With the FTTB architecture, the telco will drive fiber into Multitenant Dwelling Units (MDUs) and use the existing copper in the building riser to deliver higher speed broadband data services and video services to each resident.

Memet Atalay, Türk Telekom vice president of Operations, said that Alcatel-Lucent's fiber-to-the-building solution "helps us prepare for a long-term network transformation, leveraging a smart mix of copper and fiber access technologies to realize the highest speeds in the most cost-effective way."

Atalay added that the FTTB hybrid copper/fiber approach "is beneficial to all our customers--as we will be able to connect many more households to our high-speed network while staying within our budget."

Being an incumbent telco, the FTTB approach enables Türk Telekom to leverage their existing copper investment, while being able to support higher speed video services that customers desire, but have been only traditionally able to get from a cable company.

This deployment follows a trial that Türk Telekom began with Alcatel-Lucent to examine the potential benefits not only of VDSL2 and FTTB, but also the possibilities of other techniques such as VDSL2 Bonding, Vectoring, and DSL Phantom Mode, a technology that advocates say can deliver VDSL2 speeds up to 300 Mbps on short copper loops.

For Alcatel-Lucent, which has been continually garnering VDSL2 deployments with a number of Asia-Pacific and European providers, including a recent agreement with Belgacom, the Türk Telekom deployment serves as another proof point of its copper-based last mile approach. To date, the vendor claims to be supporting 90 VDSL2 projects.
