United Arab Emirates (UAE) operator Du and equipment vendor Nokia have carried out a successful lab trial of time and wavelength division multiplexing passive optical network (TWDM-PON) fibre technology, reaching aggregate speeds of 40Gbps. Du says the test paves the way for the implementation of 5G and Internet of Things (IoT) systems, and will help Dubai to become a smart city role model. Du currently offers peak download speeds of 1Gbps on its commercial fibre access networks.
