Abstract

We have tested experimentally the use of low cost DFB pulsed sources with narrow spectral bandwidth for all optical en/decoding based in Direct Sequences coherent technique and employing SSFBG which can be considered like a low cost alternative for header generation and recognition in PLS networks. The working principle was proven employing 20 ps pulses and SSFBGs designed with chip rates of 104 and 174 Gchips/s, obtaining an ACP versus XC ratios of 9 and 7 respectively.
