Abstract
The deployment of more economical and cost-effective wavelength division multiplexing (WDM) solutions for access and metro networks still remains a key research focus. This paper reports on significant performance enhancement improvements of an economical, four channel totally incoherent spectrum-sliced DWDM system using a single high-powered LED source and incorporating semiconductor optical amplifiers (SOAs) as pre-amplifiers on each channel. The total length of the link ran for an unsurpassed maximum of 650 km at 10 Gb/s, whilst still yielding reasonable Q-factors and very high signal-to-noise ratios (SNRs).
Keywords: spectrum, slicing, amplifier, link, signal-to-noise ratio
