Abstract

Experimental investigation has been conducted on the influence of optical fiber temperature variations on 2-Dimension Wavelength/Hopping Time/Spreading Incoherent Optical Code Division Multiple Access (2-D WH/TS iOCDMA) codes. Our experimental results show that in the literature reported approaches assuming a temperature induced coefficient (Dtemp) in optical fiber being a constant are only accurate when the selection of code carriers’ wavelengths is from a relatively narrow spectral interval. This paper shows that if the selection of code carriers’ wavelengths is from a wider spectral interval, neglecting to mitigate the wavelength dependency of (Dtemp) would have a significant impact on the recovered iOCDMA Autocorrelation function.
