Australians get double broadband boost with new fiber trials

This week the Australian National Broadband Network (nbn) said it has had some extraordinary success using fiber technologies from the Alcatel side of Nokia, getting a single fiber to carry 102 Gbps, using multiple different passive optical network (PON) based protocols. nbn said it has successfully tested Nokia’s universal NG-PON in a lab, using NG-PON2, XGS-PON and GPON delivery across the same fiber. This, it says, will provide a simple upgrade path from current fiber technology used in FTTP deployments, because it can be deployed as an overlay on existing fiber. TWDM-PON provides four or more wavelengths on a fiber, each capable of supporting asymmetrical or symmetrical bit rates of 2.5Gbps or 10Gbps for a total of 40Gbps. XGS-PON uses…
