Real-Time Diverse Fiber Sensing Multi-Event Detection using Phase OTDR Measurements
Konstantinos Alexoudis, Jasper Müller, Sai Kireet Patri +6
We demonstrate an experimental phase optical time-domain reflectometry (OTDR) system capable of simultaneous detection and classification of various environmental events, such as w…
A Transformer-Based Approach for Diagnosing Fault Cases in Optical Fiber Amplifiers
Dominic Schneider, Lutz Rapp, Christoph Ament
A transformer-based deep learning approach is presented that enables the diagnosis of fault cases in optical fiber amplifiers using condition-based monitoring time series data. The…
Simultaneous Temperature and Acoustic Sensing with Coherent Correlation OTDR
André Sandmann, Florian Azendorf, Michael Eiselt
Superimposed temperature variations and dynamic strain applied through a 400 Hz acoustic signal on a 195 m single-mode fiber section are successfully measured using a coherent corr…
Reconfigurable Optical Networks with Self-Tunable Transceivers: Implementation Options and Control
Michael H. Eiselt
This paper reviews methods for autonomous tuning of optical transceivers, based on an overhead management channel between the modules on both sides of the link. Different implement…
Lifetime Prediction of 1550 nm DFB Laser using Machine learning Techniques
Khouloud Abdelli, Danish Rafique, Helmut Griesser +1
A novel approach based on an artificial neural network (ANN) for lifetime prediction of 1.55 um InGaAsP MQW-DFB laser diodes is presented. It outperforms the conventional lifetime…
Optical Fiber Fault Detection and Localization in a Noisy OTDR Trace Based on Denoising Convolutional Autoencoder and Bidirectional Long Short-Term Memory
Khouloud Abdelli, Helmut Griesser, Carsten Tropschug +1
Optical time-domain reflectometry (OTDR) has been widely used for characterizing fiber optical links and for detecting and locating fiber faults. OTDR traces are prone to be distor…
