Raman Amplification in Optically High-Powered Data Link Dedicated to a 10 km Long Extension for Submarine Cabled Observatories
Résumé
We describe a quasi-all-optical extension dedicated to simplify the deployment of submarine cabled observatories. Based on power-over-fiber technologies, high power supply and data are both transmitted in one optical fiber of few kilometers. We study the Raman amplification on the down and up-stream data in static regime with the high optical power varying from 100 mW to 4 W over a 10 km long single-mode optical fiber. We focus on the data optical budget and signal to noise ratio dependence with respect to the high optical power value and the data optical wavelength.
