A novel ultra-long distributed vibration sensor using forward transmission, coherent detection, and a frequency-shifted optical delay line is proposed and experimentally demonstrated. In the propos…
In this article, a beyond 1.6 Tb/s net rate pulse amplitude modulation (PAM) communication system is experimentally demonstrated for 20 m rack-rack optical interconnects with low cost intensity mod…
Anisotropic diffusion (AD) is employed to enhance the signal-to-noise ratio (SNR) of Brillouin distributed optical fiber sensor. A Brillouin optical time-domain analyzer (BOTDA) with 99-km-long fib…
Efficient synchronization is of great importance for fiber optical coherent communication system. Here, we propose an accurate and low-complexity timing/frequency synchronization scheme based on sp…
Traditional vibration pattern recognition of φ-OTDR system was operated by event-based feature extractors. The proposed adjacent Spearman correlation assisted algorithm can be considered as impact…
We propose a novel bit error rate (BER) estimation scheme based on a k-means clustering algorithm assisted Gaussian approach (GA). This method can implement accurate BER estimation within a short s…
