FPGA-Based Experimental Analysis of Fixed-Point Precision Impact on SOP Estimation in Coherent Communications Receivers
Geraldo Gomes, Rafael Vieira, Hani Kbashi +8
We experimentally evaluated the sensing-communication trade-off from the fixed-point precision MIMO equalizer using FPGA. At 7-bit, noise floor drops 100x and angular error 63%, bu…
Net 835-Gb/s/λ Carrier- and LO-Free 100-km Transmission Using Channel-Aware Phase Retrieval Reception
Hanzi Huang, Haoshuo Chen, Qian Hu +9
We experimentally demonstrate the first carrier- and LO-free 800G/λ receiver enabling direct compatibility with standard coherent transmitters via phase retrieval, achieving net 83…
Distortion-Aware Phase Retrieval Receiver for High-Order QAM Transmission with Carrierless Intensity-Only Measurements
Hanzi Huang, Haoshuo Chen, Qi Gao +7
We experimentally investigate transmitting high-order quadrature amplitude modulation (QAM) signals with carrierless and intensity-only measurements with phase retrieval (PR) recei…
Real-Time Monitoring of Cable Break in a Live Fiber Network using a Coherent Transceiver Prototype
Mikael Mazur, Lauren Dallachiesa, Roland Ryf +10
We monitor a 524km live network link using an FPGA-based sensing-capable coherent transceiver prototype during a human-caused cable break. Post-analysis of polarization data reveal…
Advanced Distributed Submarine Cable Monitoring and Environmental Sensing using Constant Power Probe Signals and Coherent Detection
Mikael Mazur, Nicolas K. Fontaine, Megan Kelleher +6
In this work we demonstrate an FPGA-based coherent optical frequency domain reflectometry setup for cable monitoring. Using coherent detection for averaging and narrowband filterin…
Transoceanic Phase and Polarization Fiber Sensing using Real-Time Coherent Transceiver
Mikael Mazur, Jorge C. Castellanos, Roland Ryf +15
We implement a real-time coherent transceiver with fast streaming outputs for environmental sensing. Continuous sensing using phase and equalizer outputs over 12800km of a submarin…
