Colorless Operation of WDM-PON Employing Uncooled Spectrum-Sliced Reflective Semiconductor Optical Amplifiers

We demonstrate a low-cost wavelength- division- multiplexed passive optical network based on colorless uncooled spectrum-sliced reflective semiconductor optical amplifiers. In this network, we achieve bit-error rates of better than $10^{-10}$ over 32 100-GHz-spaced channels from 0 $^{\circ}$C to 60 $^{\circ}$C in 155-Mb/s transmissions. The penalties due to dispersion effect and Rayleigh backscattering interference over 25 km are almost negligible. We also present colorless operations over 16-channel coverage in outdoor temperature range.
