Huawei and Turkcell Superonline announce first commercial directionless, colorless WSON application

Huawei, a provider of telecommunications network systems, and Turkcell Superonline have implemented the first directionless and colorless Wavelength Switched Optical Network (WSON) application in the Istanbul metro network. WSON, the enhanced version of Automatically Switched Optical Network (ASON), is based on the DWDM transmission network, having optical level switching capabilities.

Huawei, a provider of telecommunications network systems, and Turkcell Superonline have implemented the first directionless and colorless Wavelength Switched Optical Network (WSON) application in the Istanbul metro network. WSON, the enhanced version of Automatically Switched Optical Network (ASON), is based on the DWDM transmission network, having optical level switching capabilities.

"The large volume of traffic passing through the Turkcell Superonline network has been secured with the highest possible protection level, thanks to the directionless and colorless WSON application. We put this application in place together with Huawei in Istanbul, poised to become the world's newest Internet base due to its geostrategic location through the Turkcell Superonline's infrastructure investments," says Dr. Muhittin SAYIN, Turkcell Superonline's chief technical officer.

"Huawei is one of two companies providing solutions for Active Ethernet Access and Gigabit Passive Optical Access Network Technologies reaching Turkcell Superonline home users," explains Philip Zhihui Liang, general manager of Huawei Turkey. He expects Turkcell Superonline to transform the "Silk Road" into the "Fiber Optic Road." "This application is a first in the commercial world," Liang says.

"Having the first WSON enabled network in Turkey and commercially in the world, there is no doubt that Turkcell Superonline raised the bar in terms of service quality and network reliability,” mentions Huawei Turkcell Superonline Account Manager Emre Altinok.

Designed and implemented by Turkcell Superonline and Huawei, the Istanbul Metro WSON application is the first commercial project of its kind with respect to realization via upgrade over a live network that carries commercial services and its advanced optical switching technology (independent of direction and wavelength), according to a spokesperson. In essence, WSON technology enables the uninterrupted flow of traffic to be transferred to alternative lines in case of multiple system failures and/or intersystem fiber cuts, which may occur in DWDM networks. The achievement is due to the smart signalization established by WSON between the applied network's systems, adds the spokesperson.
