Presentamos un interrogador de red de Bragg de fibra óptica de alta velocidad basado en un interferómetro activo de Sagnac y demodulación de portadora generada por fase, realizada en tiempo real mediante un sistema FPGA de bajo coste. El sistema cuenta con un ancho de banda de detección de 280 kHz y una frecuencia de muestreo de 1 MS/s, e implementa un esquema de mezcla multitono para reducir la distorsión. We present a high-speed fiber Bragg grating interrogator based on an active Sagnac interferometer and phase-generated-carrier demodulation performed in real time by a low-cost FPGA system. The system has 280kHz detection bandwidth and 1MS/s sampling rate, and implements a multitone-mixing scheme to reduce distortion.
