چکیده
Dense Wavelength Division Multiplexing (DWDM) system is limited by different impairments like optical attenuation, crosstalk, chromatic dispersion, polarization mode dispersion, Scattering etc. All of these impairments restrict the transmission distance and bandwidth. In the Present Scenario the DWDM system needs significant improvement, where analyzing the crosstalk of an Acousto-Optic Tunable Filter (AOTF) based Optical Add/Drop Multiplexer (OADM). This paper conducts a comprehensive study of DWDM system and extracts the optimum performance of the overall system by increasing the channel spacing of the AOTF with a significant improvement of signal to crosstalk ratio with channel spacing and reduced bit error rate as the bandwidth of the channel is increased accordingly.

In this paper, we demonstrate a novel all-fiber wavelength-tunable acoustooptic switch utilizing intermodal coupling in a two-mode fiber (TMF). Its all-fiber configuration consisting of a fiber acoustooptic tunable filter and a mode-selective coupler results in the low loss ( 2 dB) operation. The operating bandwidth 50 nm, the switching time of 40 sec, and the crosstalk of 20 dB were achieved. ...
