ABSTRACT
The results of a range of experimental characterization exercises of interferometric noise (IN) for the case of
a representative 2-D time spreading wavelength-hopping (2-D TW) optical code family are presented.
Interferometric noise is evaluated at a data rate of 2.5 Gbps within an OCDMA network emulation test bed
established utilising fibre Bragg grating encoders/decoders. The results demonstrate that this form of noise
introduces significant system power penalties and must be taken into consideration in any OCDMA network
designs and implementations.
Keywords: optical code-division multiple access (OCDMA), time-wavelength optical codes, beat noise,
fibre Bragg grating coders.
