French equipment vendor Alcatel-Lucent and mobile operator Zain Saudi Arabia have announced the completion of an Agile Optical Network to provide ultra-broadband access throughout Saudi Arabia. According to a vendor press release, the deployment was completed in order to support the increasing demand for network capacity over Zain’s Long Term Evolution (LTE) networks. The fibre-optic backbone network is based on converged wavelength division multiplexing/optical transport network (WDM/OTN) technology, enabling Zain to provide 100Gbps capability throughout the country’s main metros. Alcatel-Lucent’s 1830 Photonic Service Switch (PSS) supports capacity of up to 8.8Tbps over a single optical fibre. Further, the two companies are also conducting a trial of 400Gbps data transmission over an existing optical link carrying live network traffic in the major western city of Jeddah. Alcatel-Lucent’s 400G optical solution is based on the 400Gbps Photonic Service Engine (PSE) platform.
