Pulse broadening is prominent performance degrading factor which limits total speed and
distance coverage of optical communication systems (OCS). In order to compensate the …

Chromatic dispersion (CD) has a significant impact on a quality of transmitted optical signal
in high-speed fiber optic communication systems with data rates up to 10 Gbit/s, and as a …

This paper contains an analyzing investigation of 32 channel-10 Gbps DWDM-PON FTTH
Simulate reaching a village in suburban area in environment that cannot put any sub node …

The increasing number of end-users and growing demand for higher data rate affect fiber-
optical transmission systems (FOTS), which need to catch up with the different performance …

In this paper, dispersion compensating fibers are used to compensate for the positive
dispersion accumulated over the length of transmission fiber. Pre and post dispersion …

Optical communication is a prominent technology for future communication sector because
of its low power consumption, high capacity and lower attenuation. It is also affected by the …

This paper investigates the direct gigabit modulation characteristics of semiconductor lasers
using the return to zero (RZ) and non-return to zero (NRZ) formats. The modulation …

Simultaneous propagation of different modulation formats in WDM systems are evaluated
numerically with OptSim simulation software at a bit rate of 2.5 Gbit/s and 10 Gbit/s using 80 …

25 system–24.1 dBm; and for a 16-channel system–26.3 dBm). These optimal parameters
were found in order to get the highest system performance, respectively, the lowest BER …

As WDM channel spacing continues to decrease in size, we demonstrate the minimal
allowed channel spacing in HDWDM systems. According to experimental model we have …
