Assessment on the in-field lightpath QoT computation including connector loss uncertainties
Alessio Ferrari;Karthikeyan Balasubramanian;Mark Filer;Yawei Yin;Esther Le Rouzic;Jan Kundrat;Gert Grammel;Gabriele Galimberti;Vittorio Curri
Reliable and conservative computation of the quality of transmission (QoT) of transparent lightpaths (LPs) is a crucial need for software-defined control and management of the wavelength division multiplexing optical transport. The LP QoT is summarized by the generalized SNR (GSNR) that can be computed by a QoT estimator (QoT-E). Within the context of network automation, the QoT-E must rely only o...Show More

We compare measured QoT on production network to GNPy predictions, showing an excellent accuracy for 40 channels on two paths. Transmission exceeds 2000 km on mixed-fiber hybrid amplified links. Non-conservative prediction is observed only in 23% of cases and the inaccuracy is limited to 0.3 dB.Show More

GNPy is an open source project of the Telecom Infra Project (TIP). It aims at the development of a software library for the abstraction of physical layer data transport, implemented as wavelength division multiplexing (WDM) through open-source code and open APIs, with the purpose of automatizing disaggregated, multi-vendor open optical networks. We first introduce the GNPy library of applications ...Show More

We present GNPy: an open source software abstracting the physical layer of an optical network. GNPy has been developed by the physical simulation environment (PSE) team in the telecom infra project (TIP) consortium. We experimentally demonstrate the accuracy of the tool in predicting the quality of transmission (QoT) in a network, and then we demonstrate how GNPy can be used to address physical la...Show More

GNPy: an open source application for physical layer aware open optical networks
Alessio Ferrari;Mark Filer;Karthikeyan Balasubramanian;Yawei Yin;Esther Le Rouzic;Jan Kundrat;Gert Grammel;Gabriele Galimberti;Vittorio Curri
In this paper, we describe the validation of GNPy. GNPy is an open source application that approaches the optical layer according to a disaggregated paradigm, and its core engine is a quality-of-transmission estimator for coherent wavelength division multiplexed optical networks. This software is versatile. It can be used to prepare a request for proposal/request for quotation, as an engine of a w...Show More
