In last decade or so, due to the emergence of various high bandwidth applications, there was a strong completion between various access networks. As the bandwidth is increasing day-by-day and in the present scenario various data intensive applications have led to the introduction of optical fiber as means of communication as a typical access network. As the optical access network provides a huge bandwidth and can be considered for long distance communication. The exceptionally high bandwidth of optical fiber can be explored by employing WDM (Wavelength-Division Multiplexed) technique in long reach optical access networks as WDM provides high bandwidth efficiency.
