Dense-wavelength-division multiplexing (DWDM)-centric metro/aggregation networking is defined as predominantly using packet aggregation at the edges of the aggregation domain, while using DWDM at the center of the network.
There are many factors that have contributed to the extensive use of fiber in telecom networks. As a result of the bandwidth and speed it can offer per dollar spent, the use of fiber is becoming more extensive being pushed deeper and deeper – particularly in the last mile. In a field trial carried out by Ericsson and Telstra, technologies to meet operator demand for seamless upgrade of networks were put to the test.
Telstra and Ericsson have successfully conducted the first trial of 1Tbps technology in Australia over 995km of its existing optical fiber network between Sydney and Melbourne.
Gemma Vall-Llosera, an Ericsson Research specialist in high-speed access and architecture, takes us on a tour of some state-of-the-art demos in the latest Follow the Expert film.
Infonetics Research analyst Jeff Heynen highlights the challenges facing fixed-broadband operators, and predicts how increasing uptake of cloud-based services may impact on access networks.
