Opis:: In this paper we present analysis of the influence of filter characteristics of Wavelength Division Multiplexing network components and transmission parameters over inter-channel crosstalk for symmetric and asymmetric transmission. The simulation was carried out for bit rate 10 Gb/s, 40 Gb/sand 100 Gb/s considering the following modulations: DPSK, DQPSK and OOK. The obtained results show that OOK and DQPSK modulation are better than DPSK modulation in terms of crosstalk occurring during the transmission of signals in Wavelength Division Multiplexing systems.

Opis:: Network on chip (NoC) is presented as a promising solution to face off the growing up of the data exchange in the multiprocessor system-on-chip (MPSoC). However, the traditional NoC faces two main problems: the bandwidth and the energy consumption. To face off these problems, a new technology in MPSoC, namely, optical network-on-chip (ONoC) has been introduced which it uses the optical communication to guaranty a high performance in communication between cores. In addition, wavelength division multiplexing (WDM) is exploited in ONoC to reach a high rate of bandwidth. Nevertheless, the transparency nature of the ONoC components induce crosstalk noise to the optical signals, which it has a direct effect to the signal-to-noise ratio (SNR) then decrease the performance of the ONoC. In this paper, we proposed a new system to control these impairments in the network in order to detect and monitor crosstalk noise in WDM-based ONoC. Furthermore, the crosstalk monitoring system is a distributed hardware system designed and test with the different optical components according the various network topology used in ONoC. The register-transfer level (RTL) hardware design and implementation of this system can result in high reliability, scalability and efficiency with running time less than 20 ms.
