Ericsson Completes 100G Trial

Broadband networks around the globe are continuously expanding at high pace and there is a high interest among operators to upgrade existing 10G optical transport solutions to meet the capacity demand. Although there are standardized technologies at hand, Ericsson continues to seek new alternative technologies to improve the upgrading of existing optical connections in the networks while saving cost. A research team at Ericsson, in cooperation with a Swedish ICT research company, has now completed a field trial using advanced modulation and detection techniques. The trial running 112 Gbps on a single optical wavelength over an 824 km installed fiber route proved to be prosperous. As each fiber supports a number of wavelengths, the overall capacity of the fiber can be immense with this alternative technique. The upgrade procedure to 100G was successful and it was performed without touching any equipment on the path – which is key in commercial scenarios as it means quicker time to market and substantially lower deployment cost for the operator. The trial result points at a large potential when it comes to cost savings and the increase in utilization of the inherent capacity potential of the fiber. Ericsson AB
