Impact of Filter Characteristics and Optical Signal Parameters on Interchannel Crosstalk

Kowalczyk A., Perlicki K.

International Journal of Electronics and Telecommunications

2014

Vol. 60, No. 1

83-87

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.

Raman Polarization Pulling and Amplification for Polarization Division Multiplexing Transmission System

Perlicki K.

International Journal of Electronics and Telecommunications

2011

Vol. 57, No. 4

519-522

The numerical modelling of the Raman polarization attraction and amplification process in the telecommunication band around 1550 nm is presented. The possibility of achieving both polarization pulling and amplification in Polarization Division Multiplexing transmission system by exploiting the polarization dependence of stimulated Raman scattering is investigated. The acceptable crosstalk for the Polarization Division Multiplexing transmission systems was achieved for some attraction/amplification block parameters.
