Abstract

In this paper, we examine the amplitude and the duration of a wavelength drift of the tunable lasers at the most crucial moment, which is the time after the wavelength switch and measure the impact of this drift on the performance of the DWDM system spaced by 12.5 GHz. The adjacent channel interference is examined for two cases: firstly when the TL is modulated with base-band (BB) data, secondly when subcarrier multiplexing (SCM) is used
