Huawei and Turkcell Group company Superonline implemented a directionless and colorless WSON (Wavelength Switched Optical Network) application in the Istanbul metro network.
As the enhanced version of ASON (Automatically Switched Optical Network), WSON is based on the DWDM transmission network, having optical level switching capabilities.
Designed and implemented by Superonline and Huawei through intensive engineering works, the Istanbul Metro WSON application is said to be the first successful commercial project of its kind with respect to realisation via upgrade over a live network that carries commercial services and its advanced optical switching technology (independent of direction and wavelength).
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 fibre cuts, which may occur in DWDM networks. This is due to the smart signalisation established by WSON between the applied network’s systems.
via Huawei, Superonline implement WSON app in Istanbul (Turkey).
