“…The extractor uses the North Bound Interface (NBI) of the NMS to provide: i) topology-related data that mainly concern nodes, network elements cards and links; ii) service-related data that provide for instance the modulation format, bit rate and routing of each service; and iii) performance-related data that provide the output power of each amplifier and the BER of each service. The BER is transformed to SNR using transponder B2B characterization as in [5] . Data extracted from the NMS are not exhaustive, which leads us to complete the models with external information such as equipment characterizations and specifications.…”

“…Also, if the physical conditions in the workplace and telecommuting are appropriate, it will improve the productivity and improve the quality of employees' work. Grammel et al (2018) in a study, entitled Physical Simulation Environment of Telecommunications Infrastructure Project (TIP), believe that the physical condition of the workplace usually results in job satisfaction if it is comfortable and away from danger. Also, the physical environment plays an essential role for employees and proper design of the work environment can affect the feeling of comfort and safety, motivation, job satisfaction and overall productivity of employees.…”

PurposeTelecommuting can reduce traffic congestion, energy consumption, prevalence and a death toll of COVID-19 among employees due to less transportation and fewer physical contacts among employees, on the one hand, and efficiently develop their use of information and communications technology, on the other hand. In this regard, the present study aims to explore antecedents and consequences of telecommuting in public organizations.Design/methodology/approachThe study used a descriptive survey method to collect data. The statistical population includes all employees of government organizations in West Azerbaijan province in 2020, which according to the collected information, their number is equal to 63,079 employees. Based on Cochran's formula, a sample size of 686 people was obtained; stratified random sampling was used to select sampling. The process of calculating the sample volume was such that after referring to the preliminary sample and processing the collected data, the variance of the given answers was approximately 0.446. After obtaining the variance of the data, assuming a maximum acceptable error of 5% and a significance level of 0.05, the Cochran's formula calculated the sample size to be 686 people. In order to collect and measure data for the study, a standard questionnaire and the collected data were analyzed using structural equation modeling.FindingsFindings indicate that there is no meaningful relationship between the employees' physical job conditions or the quality of their life with telecommuting and that telecommuting does not have a significant effect on their life. However, job burnout, training and telecommuting experience have a significant positive effect on telecommuting, which in turn has a positive and significant effect on job security, job flexibility, organizational performance and overall productivity of employees.Research limitations/implicationsThis research is a cross-sectional study, and its data have been collected in a certain period of time, while longitudinal research can provide a richer result. Future research can benefit from the impact of employee isolation and telecommuter organizational commitment.Originality/valueThis study hopes to contribute to the increase of the scientific knowledge in the telecommuting field and to allow organizations to rethink the telecommuting strategies to optimize resources and costs and to improve the organization's productivity without harming the quality of life and well-being of their workers.

“…For each fiber span, this loss fixes the actual power of the spectral load, producing different magnitudes of NLI. Nevertheless, the prediction capability of P NLI is in general very good once a suitable mathematical model is applied to the system under analysis [15,35]. Consequently, in this work, we focus our investigation only on the OSNR component of the GSNR.…”

“…In fact, the ASE noise magnitude depends on the working point of erbium-doped fiber amplifiers (EDFAs) [13]; this in turn depends on the spectral load [14]. On the contrary, the NLI can be accurately predicted when the ASE noise accumulation is well characterized [15].…”

The reduction of system margin in open optical line systems (OLSs) requires the capability to predict the quality of transmission (QoT) within them. This quantity is given by the generalized signal-to-noise ratio (GSNR), including both the effects of amplified spontaneous emission (ASE) noise and nonlinear interference accumulation. Among these, estimating the ASE noise is the most challenging task due to the spectrally resolved working point of the erbium-doped fiber amplifiers (EDFAs), which depend on the spectral load, given the overall gain profile. An accurate GSNR estimation enables control of the power optimization and the possibility to automatically deploy lightpaths with a minimum margin in a reliable manner. We suppose an agnostic operation of the OLS, meaning that the EDFAs are operated as black boxes and rely only on telemetry data from the optical channel monitor at the end of the OLS. We acquire an experimental data set from an OLS made of 11 EDFAs and show that, without any knowledge of the system characteristics, an average extra margin of 2.28 dB is necessary to maintain a conservative threshold of QoT. Following this, we applied deep neural network machine-learning techniques, demonstrating a reduction in the needed margin average down to 0.15 dB.
