  • Jan 2009
A new programmable AWG-Based spectral phase coding OCDMA scheme with changing phase state mechanism is configured over a fiber-to-the-home (FTTH) network. In order to improve BER and confidentiality of conventional spectral phase coding (SPC) OCDMA scheme, the proposed scheme employ complementary SPC code with Hadamard code as signature address cod...
