Abstract
Point-to-multipoint (P2MP) optical coherent transceivers, which take advantage of digital subcarrier multiplexing, can greatly simplify design, planning and operations in next-generation high-capacity metro aggregation networks.In this paper, we investigate their utilization over two complex network scenarios: urban/industrial and suburban/rural. We provide evidence that with P2MP technology, it is possible to achieve a 32% Capital Expenditure (CAPEX) savings compared to the use of traditional point-to-point (P2P) transceivers, and 41% in the case of increased aggregation in a short-term scenario.
