Based on a variety of long-term network traffic data from different geographies and
applications, in addition to long-term scaling trends of key information and communication …

To support the development of intelligent optical networks, accurate modeling of the physical
layer is crucial. Digital twin (DT) modeling, which relies on continuous learning with real-time …

For reliable and efficient network planning and operation, accurate estimation of Quality of
Transmission (QoT) before establishing or reconfiguring the connection is necessary. In …

The recent acceleration in fiber-to-the-home deployment worldwide along with the emerging
5G communications are pressuring network operators to enhance their networks to serve …

To deal with the challenging requirements of metropolitan area networks (MANs), it is
essential to design cost-effective systems that can support high capacity and dynamic …

We present a detailed experimental analysis of the penalty introduced by optical filtering
during propagation of a high-speed coherently detected signal. We investigate the …

Abstract Coherent Optical Orthogonal Frequency Division Multiplexing (CO-OFDM) based
Elastic Optical Network (EON) is one of the emerging technologies being considered for next …

Measuring the optical signal to noise ratio (OSNR) at certain network points is essential for
failure handling, for single connection but also global network optimization. Estimating …

The power consumption of telecommunication equipment has been identified as a relevant
contributor to global energy consumption. In fact, new-generation optical transponders …

Optical networks have historically been overprovisioned for physical-layer conditions and
capacity and, as such, operate uninterrupted over several years. By reducing system …
