AbstractIn this paper, we investigate the effect of channel spacing and chromatic dispersion on four wave mixing in WDM system. Dominating effect of four wave mixing is minimizing at maximum value of dispersion and channel spacing. Power of FWM, Q-factor, bit error rate and output spectrum is used to measure the performance of system.

Active Channels

The channels contributed in creating new pulse during the four-wave mixing (FWM) process are a subject of two features: the first is the fact that all channels are not working with probability %100 , but with p probability. Second, the bits transmitted are not all "1". Therefore, the equation of power generated using these features should be corrected. On the other hand, the use of equally spaced channels wavelength divisionmultiplexing (ESC WDM) system cause an increase in the number of new components generated that interfere with the active channels and increase the bit error rate. In order to reduce these interferences, we have provided an unequally spaced channels wavelength division-multiplexing (USC WDM) system composed of several sets. Each set consists of only four channels, which locations have been selected to cause no interferences between them. Neighboring sets are separated by a frequency spacing which should be large enough to reduce the interferences between the sets, andsmall enough to increase the total number of channels of the system.

Fiber Nonlinearities

AbstractThe fiber nonlinearities are one of the main performance limiting factors in any optical communication system. There are several parameters that effectively contribute in mitigation of these fiber nonlinearities such as fiber dispersion, effective area of fiber core, etc. Here, we have investigated the four wave mixing (FWM) nonlinear impairments in 16-channel WDM system. The FWM crosstalk becomes very critical to handle for long haul transmission systems at high power levels. Here, 16 channels WDM is being implemented and its performance is evaluated in terms of bit error rate (BER), Q factor, etc. for distance transmission upto 500 km.

AbstractAim and scope of this study is to simulate the performance signature of optical inter satellite links based booster Erbium doped fiber amplifier (EDFA) and receiver preamplifiers. The study is simulated to demonstrated the effect of changing the propagation distances between satellites spacing based on the booster EDFA and receiver preamplifiers. Signal power amplitude, Max. Q factor, and min bit error rate are investigated against the input power variations.
