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

Abstract

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> We demonstrate a low-cost wavelength- division- multiplexed<?Pub _nolinebreak=""?> passive optical network based on colorless uncooled spectrum-sliced reflective semiconductor optical amplifiers. In this network, we achieve bit-error rates of better than <emphasis><formula formulatype="inline"><tex>$10^{-10}$</tex> </formula></emphasis> over 32 100-GHz-spaced channels from 0 <emphasis><formula formulatype="inline"><tex>$^{\circ}$</tex></formula></emphasis>C to 60 <emphasis><formula formulatype="inline"><tex>$^{\circ}$</tex></formula></emphasis>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. </para>
