Paper Abstract

Interferometric noise(IN) is essential to an OCDMA system, since the tree topology of optical coder and decoder induces the multi-path transmission of signal from same laser. Signal noise ratio(SNR) including MAI, optical beat noise(OBN) and IN is firstly deduced in this paper. Numerical and experimental results show that in one dimension OCDMA system with narrow line width laser, interferometric noise is great enough to limit system performance with relative high bite rate and small frequencies' difference; while in tow dimension OCDMA system, interferometric noise is a minor factor compared to OBN.
