The exponential increase in transmission capacity triggered the era of fast and reliable data transfer techniques through fiber optic networks. This has led to the exploration of new options in the field of spectrally efficient systems suitable for extremely high data rates. Consequently, there is a gradual transition from existing systems with a 10 Gbps transmission rate to 40 Gbps optical systems and even up to 100 Gbps. However, with the increase in network transmission capacity, the optical signal performance requirement is also increased to ensure acceptable bit error rate (BER) in the receiver. However, increasing transmission power leads to a distortion of the transmitted signal due to the nonlinear Kerr effects or interference between adjacent channels. These are the main limitations that set the upper limit of the maximum effective SNR (Signal-to-Noise Ratio) of the optical link and limit the performance of the whole system. On the other hand, linear effects such as chromatic dispersion (CD), optical SNR (OSNR), spontaneous photon emission, optical fiber loss, or channel overlapping through long stretches of optical fibers are also important factors that need to be considered when designing DWDM (Dense Wavelength Division Multiplexing) system.

Pulsed signals distortions in multichannel conerent detection transmission systems caused by selfphase modulation and cross-phase modulation in optical fiber. T-Comm, vol. 14, no.1, pр. 4-12. (in Russian) Исследуется влияние эффектов фазовой самомодуляции (ФСМ) и фазовой кросс-модуляции (ФКМ) на помехоустойчивость передаваемых импульсных сигналов в многоканальной системе передачи со спектральным уплотнением в зависимости от параметров системы передачи: уровня суммарной мощности излучения в оптоволокне и типа линейных кодов. На приемной стороне, после когерентного фотодетектирования импульсных сигналов анализируются полученные глаз-диаграммы. Критерием оценки влияния ФСМ и ФКМ на помехоустойчивость передаваемых сигналов принят Q-фактор, который вычисляется графическим способом с помощью глаз-диаграммы. Имитационная модель многоканальной волоконно-оптической системы передачи со спектральным разделением каналов реализована в среде моделирования MathCAD. Влияние явлений ФСМ и ФКМ на передаваемый сигнал имитируется как искажение фазы этого сигнала при его распространении по стандартному одномодовому волокну и преобразование этих искажений в амплитудные при фотодетектировании. Показано, что изза влияния ФСМ и ФКМ при увеличении уровня суммарной мощности излучения в оптоволокне происходит ухудшение показателя качества сигнала. В 128-канальной системе передачи с канальной скоростью передачи данных 40 Гбит/с, увеличение суммарной мощности с 2 до 30 мВт приводит к снижению величины Q-фактора при использовании линейного кода передачи NRZ в 8 раз и при использовании кода RZ в 9 раз. В работе показано, что по сравнению с линейным кодом NRZ, использование кода RZ позволяет уменьшить влияние ФСМ и ФКМ и увеличить Q-фактор в среднем в 1.7 раза. Полученные результаты могут быть использованы при проектировании многоканальных волоконно-оптических систем передачи со спектральным разделением каналов для оценки потенциального вклада явлений ФСМ и ФКМ в снижение помехоустойчивости системы.

“…A waveguide arrangement into a grate are frequently called also PHASAR -Phased Arrays, or WGR -Waveguide Grating Routers. The AWG multiplexors/demultiplexors, together with the fibre Bragg grating and the selective filters, are the main parts of the WDM systems [8][9][10]. The fibre is connected to the waveguide which continues after a short distance as several parallel narrow waveguides.…”

This article focuses on the creation of the sixteen-channel DWDM (Dense Wavelength Division Multiplex) system according to the recommendation ITU-T G.694.1. Currently it is not possible to form a fully optical communication system without testing all non-linear effects possibly influencing its performance. The trend in high-speed transfer communication systems is using the multiplex, so we focused on the AWG (Arrayed Waveguide Grating) multiplexor/demultiplexor. For the purpose of this article we have created a DWDM system with the speed of 10Gbps where we compared two line codes, namely NRZ (Non Return Zero) and BRZ (Bipolar Return Zero) for the channel gaps of 12.5GHz and 100GHz. The individual codes were created in the "Matlab" programme and consequently implemented into the environment generated by "OptSim" by the RSoft company. The resulting signal was evaluated based on BER (Bit Error Rate) and the connected Q-factor for the channel No.3. The created system shows the influence of the system by the non-linear effect FWM (Four Wave Mixing) during the compression between the channels. Streszczenie. Niniejszy artykuł ma na celu utworzenie szesnastowego kanału DWDM (Dense Wavelength Division Multiplex) zgodnie z normą ITU-T G.694.1. Obecnie nie jest możliwe wdrożenie w pełni optycznego systemu komunikacyjnego bez testowania wszystkich zjawisk nieliniowych, które mogą działać w danym systemie w czasie rzeczywistym. Ponieważ w systemach transmisji danych o dużej szybkości wykorzystuje się multipleks, skupiliśmy się na multiplekserze i demultiplekserze AWG (Arrayed Waveguide Grating). W artykule zbadano system DWDM o szybkości 10Gbps, porównujący dwa kody linii NRZ (Non Return Zero) i BRZ (Bipolar Return Zero) dla kanałów 12.5 GHz i 100 GHz. Poszczególne kody zostały utworzone w programie Matlab, a następnie zostały wdrożone w środowisku OptSim przez firmę RSoft. Powstały system jest obliczany na podstawie szybkości błędu bitowego BER i związanego z tym współczynnika Q dla określonego kanału nr 3. Utworzony system pokazuje wpływ na system poprzez efekt nieliniowy FWM (Four Wave Mixing) podczas kompresji między kanałami. (Wpływ FWM z multiplekserem AWG w systemie DWDM).
