“…In this case, this performance can be attributed to both the compensation behavior of the PDF inner tails (Fig. 3 (b)), and also to the increase in the number of random variables presented in (6). For the DPSK case, there is no compensatory behavior of the PDF inner tails (Fig.…”

“…In-band crosstalk is a well-known concern in the context of WDM networks using OOK signals, and is very well documented in the literature for this case [4][5][6][7][8], but not for the DPSK case. The first publication concerning the performance of DPSK signals impaired by in-band crosstalk was a paper written by Liu et al [3], where it was experimentally demonstrated that in a single interferer scenario the use of DPSK signals results in a 6 dB tolerance to in-band crosstalk relatively to OOK signals.…”

The Gaussian approximation is known to be quite accurate for estimating the system performance of an optically pre-amplified on-off keying (OOK) system in the presence of multiple in-band interferers. This paper assesses if similar accuracy can be also achieved in an optically pre-amplified differential phase-shift keying (DPSK) system. The probability density function of the decision variable at the receiver is computed as a function of the number of interferers, and it is observed that this variable statistic is clearly non-Gaussian even for a large number of interferers. It is also shown that, for a 1 dB power penalty and a 16 interferer scenario, the Gaussian approximation over-estimates the real value of the total crosstalk level by as much as 3.7 dB for DPSK signals, while for OOK signals this gap shrinks by approximately 2 dB.

“…The CW laser continuously emits and pump light signal. These signals were modulated simultaneously at 10Gb/s with a pseudorandom bit sequence (PRBS) of length 2 31 −1 [14]. PRBS is used as test pattern which always uses random bits of 0 and 1 [6].…”

This paper demonstrates the performance of erbium-doped fiber amplifier (EDFA) and avalanche photodiode receiver in a dynamic wavelength division multiplexing (WDM) system. A four channel 10 Gb/s system is taken into consideration, and the performance of EDFA is assessed. The experimental setup consists of a transmitter, a receiver, and two intermediate nodes. The transmitted system is tested for bit error rate and eye pattern at the receiver. The spectrum is also analyzed for different lengths of fiber. Add drop experiment was carried out on in which a laser source was switched on and off continuously to assess the transient response of WDM system. Then, the eye pattern is analysed in which EDFA system will provide a clear open eye with no degradation of signal.

In this paper, an analytical approach is presented to evaluate the performance of DWDM system with intensity modulation direct detection (IM/DD) due to the effects of amplified spontaneous emission (ASE) noise of optical amplifier, optical receiver noises and crosstalk. And a system has been proposed with an optimum number of amplifiers with higher gain and an improved optical receiver has been proposed. We have investigated the effects of optical amplifiers and optical receiver in the presence of crosstalk on the overall performance; in particular, Signal-to-Noise Ratio (SNR) and Bit-Error-Rate (BER) performance of a DWDM system. The system performances are evaluated for varying different amplifier gains, number of optical amplifiers, hop length, number of hops, receiver bandwidth and receiver gain considering the relationship between crosstalk and the number of wavelengths channel spacing. It is found that, the performance is highly degraded due to crosstalk and noises. As a result the system suffers significant power penalty at a given BER.
