Abstract

It is becoming increasingly vital to monitor telecommunication links during operation and installation process. By using a high peak power source and the optical time domain reflectometry technique operating at the wavelength region of 1.6 micrometers , it is possible to monitor conventional C-band Erbium-doped fiber amplifier (EDFA) systems whilst transmitting data, and to characterize losses at the higher wavelengths of extended bandwidth systems designed around the L-band EDFA systems. We describe a compact design based on Raman shifting the output of an Erbium-doped Q-switched fiber laser operating at 1.5 micrometers for obtaining a pulsed source at 1.6 micrometers .
