Abstract
Metodo di telecomunicazioni ottica a più lunghezza d'onda, che comprende generare almeno un segnale ottico di trasmissione in una banda di lunghezza d'onda prefissata, trasmettere detto segnale ottico di trasmissione attraverso una fibra ottica ad una stazione di ricezione, ricevere il segnale ottico di trasmissione attraverso un filtro a banda passante e filtrare detto segnale per lasciar passare solo detto segnale di trasmissione, in cui la banda di lunghezze d'onda é esplorata per individuarne una porzione riconoscibile dello spettro ottico in ricezione, determinando in base alle condizioni operative corrispondenti a detta porzione riconoscibile di spettro, un campo di ricerca di detto segnale di trasmissione, entro cui il segnale di trasmissione viene ricercato e riconosciuto in base al suo profilo spettrale.
