Pełny tekst źródłaIn optical fibered networks, massive monitoring generated significant interest to allow them to be more autonomous and elastic. Over the years, various monitoring techniques based on the digital signal processing at the receiver side have been proposed. Those techniques are particularly interesting since they do not require additional hardware and are less costly. In my PhD, I focused on techniques to monitor the longitudinal power of an optical link, based on the analysis of non-linear propagation effects. First, I proposed to use an existing technique to estimate the value of a power loss in a point-to-point optical link and validated it experimentally. Then, I generalized the power losses estimation method and applied it to a meshed network. Using various lightpaths on this network allowed me to show experimentally an increase of the accuracy of the estimation of loss values. To broaden the possibilities of implementation of this method, I then investigate experimentally the application of the power profile estimation technique on a long optical link to validate its use for submarine systems. Finally, I propose to use this technique to monitor another type of power losses, polarization-dependent loss (PDL). PDL is present in optical components such as switches and amplifiers. Usually, only the accumulated amount is monitored. I proposed to use a similar method as with the power losses, allowing the location of a varying PDL element and the estimation of its variation. This latest work allows us to get closer to the type of event, which is important to take smart and effective solutions

Pełny tekst źródłaIn this thesis a study of optical fiber amplifiers in the context of transparent and dynamic optical networks is performed. We propose and validate a simplified model to estimate the gain profile and amplified spontaneous emission (ASE) noise of broadband counterpumped Raman fiber amplifiers (RFAs). The proposed model requires very low computational resources and it is suitable to be used in network planning tools. Based on the proposed model, we also present an algorithm to design flat gain counter-pumped RFAs for the extended C-band with low computational requirements. We experimentally verify that the pump-reflecting RFA presents a higher transient response due to channels add/drop, when compared to the conventional counter-pumped RFA. This makes this amplifier configuration unsuitable for transparent and dynamic optical networks. To mitigate the transient response due to channel add/drop, a pumpcontrolled gain-locked system based on the monitorization of the reflected pump power is proposed and validated numerically and experimentally. Following this approach, an efficient low-cost RFA suitable for dynamic optical networks is proposed. The dependence of the dynamical response of erbium-doped fiber amplifiers (EDFAs) on the pump wavelength, pump power, and temperature due to spectral hole burning (SHB) and site dependent pumping (SDP) is experimentally investigated. A dependence of the dynamic response on the pump wavelength, for amplifiers pumped around 1480 nm, is shown. In order to explain this dependence, the impact of SDP on the performance of EDFAs pumped at wavelengths around 1480 nm is investigated, both experimentally and numerically. As a result, an improved model incorporating the SDP effect for twolevel EDFAs is derived and experimentally validated.
Nesta tese é feito um estudo sobre amplificadores de fibra ótica no contexto de redes óticas transparentes e dinâmicas. Propomos e validamos um modelo simplificado para estimar o perfil do ganho e do ruído de emissão espontânea amplificada (ASE), para amplificadores de Raman (RFAs) contra propagantes. O modelo proposto requer baixos recursos computacionais e é adequado para ser usado em ferramentas de planeamento da rede. Com base no modelo proposto, apresentamos também um algoritmo com requisitos computacionais baixos para desenhar RFAs contra propagantes com ganho constante para a banda C estendida. Verificamos experimentalmente que um RFA contra propagante com reflexo da potência da bomba devido à adição/remoção de canais apresenta uma resposta transiente mais elevada, quando comparado com um RFA contra propagante convencional. Isto torna esta configuração inadequada para redes óticas transparentes e dinâmicas. Para mitigar a resposta transitória devido à adição/remoção de canais, um sistema de controlo do ganho baseado na monitorização da potência da bomba refletida é proposto e validado numérica e experimentalmente. Seguindo esta abordagem, um RFA contra propagante eficiente e de baixo custo adequado para redes óticas dinâmicas é proposto. A dependência da resposta dinâmica dos amplificadores de fibra dopada com érbio (EDFAs) em função do comprimento de onda da bomba, da potência da bomba e da temperatura devido ao spectral hole burning (SHB) e site dependent pumping (SDP) é investigada experimentalmente. Nos resultados obtidos é mostrada a dependência da resposta dinâmica em função do comprimento de onda da bomba, para amplificadores bombeados em torno de 1480 nm. Para explicar esta dependência, o impacto do SDP no desempenho de EDFAs bombeados em comprimentos de onda em torno de 1480 nm é investigado, tanto experimental como numericamente. Como resultado, um modelo mais completo, incorporando o efeito SDP para EDFAs de dois níveis é derivado e validado experimentalmente.

Pełny tekst źródłaFirst, we study the standing-wave and the traveling-wave gain-clamping techniques when applied to a single discrete fiber Raman amplifier in the context of WDM channel add and drop. We take into account the operational regime of the amplifier and the location of the surviving channel in the amplification band. We demonstrate that the gain-clamped amplifier has to be operated in a regime below the critical regime to ensure that gain-clamping will be in effect. The efficiency of gain-clamping also depends on the feedback level of the lasing signal and on the implementation.
Next, we investigate the dynamic behaviour of a single discrete fiber Raman amplifier fed by multi-channel packet traffic. Our study shows that the efficiency of the gain-clamping technique to reduce the gain transients is dependent upon the operational regime of the amplifier and the packet duration. However, we also demonstrate that gain-clamping is not required to control the gain transients as the gain variations of the unclamped amplifier are small enough to be neglected.
We then theoretically analyse the dynamic response of cascades of discrete fiber Raman amplifiers subject to WDM channel add and drop. We consider cascades of mixed unclamped and gain-clamped amplifiers, varying the number and the position of the gain-clamped amplifiers in the cascade and taking into account the location of the surviving channel and the operational regime of the amplifiers. Our results show that the location of the gain-clamped amplifiers in a mixed cascade affects the transient characteristics and that it is possible to control the transients within tolerable limits.
Finally, we investigate the gain transients that occur in hybrid amplifiers in the presence of channel add and drop. We demonstrate that the gain-clamping technique can be used to mitigate the gain transients in hybrid amplifiers and that the surviving channel location does not influence the transient characteristics, contrary to the case of single and cascaded fiber Raman amplifiers.

Por lo tanto, el potencial se WDM-PON se debe integrar y mejorar con el fin de adaptarlo para NGPON y el futuro 5G. Hoy dia, operadores, usuarios y científicos, ven crucial augmentar la velocitat de funcionament y el alcance de las redes de acceso PON, si bien no tiene sentido conseguirlo con un coste inasequible. El UDWDM-PON puede considerarse como una solución definitiva para la red de acceso de próxima generación, capaz de proporcionar ancho de banda ilimitado para cada usuario, gracias a la detección coherente, por lo que en esta tesis se aborda su realización con un coste e integración prácticos. Con el fin de aplicarlos de manera rentable, el sistema debería exigir a las ONU que sean idénticas, si láseres preseleccionados o incoloros, y ser bidireccionales. Se desea que el conjunto de moduladores del sistema tengan en un bajo consumo, e incluso limitar el número de amplificadores. Sin embargo, para la transmisión bidireccional los efectos de retrodispersión limitarían el rendimiento si queremos volver a utilizar la portadora generada en la OLT. Por lo tanto, debemos diseñar un método para separar la longitud de onda en las transmisiones de bajada y de retorno del usuario a la central. El tradicional UDWDM-PON utiliza 2 láseres en la ONU; en esta tesis, las ONUs usan dispositivos integrados basados en un sólo DFB. ¿Cuál es la configuración más plausible? Los dispositivos fotónicos como RSOA, DEML, FML con configuraciones avanzadas se presentan en esta tesis con diferentes aplicaciones, que resuelven distintos problemas técnicos. La tesis incluye las siguientes partes: análisis y medida de dispositivos fotónicos clave para WDM-PON con modulación de fase, la independencia a la polarización de RSOA con diferentes aplicaciones, demostración de DEML con doble salida para transmisión bidireccional coherente UDWDM-PON, mitigación de AM residual de DEML para la modulación de fase, y la sintonía rápida de canal de UDWDM a través de FML.

Pełny tekst źródłaMeeting the increasing demand for highspeed data transmission requires effective solutions for mitigating nonlinearity in optical communication systems. Traditional methods like Digital Backpropagation (DBP) face significant computational challenges,rendering them impractical for real-world systems. Neural network models have emerged as a promising approach to address this issue. Two primary approaches exist for designing neural networks: model-agnostic and model-based methods. Modelagnostictechniques offer flexibility in terms of size and hyperparameters and can be placed at various positions in the receiver’s Digital Signal Processing (DSP) chain. However, they demand substantial size and extensive training data in order to operate effectively.In contrast, model-based approaches employ neuralnetworks guided by the physical model of signal propagation. These approaches tend to be more compactbut require careful initialization for proper generalization. One prominent model-based technique isLearned Digital Backpropagation (LDBP), which optimizes DBP parameters using neural networks. LDBPoffers the promise of improved performance or reduced complexity compared to DBP. This study primarilyfocuses on LDBP, introducing simplifications through ”parameter sharing” to reduce trainable parameters.Additionally, we propose repurposing the legacy Dispersion-Managed (DM) systems, by incorporatinghigher-order modulation formats such as 16- QAM and 64-QAM, to enhance data rates within these systems. A comprehensive analysis of the performance and complexity demonstrates that the proposed algorithms outperform linear equalization andDBP in various transmission systems

Pełny tekst źródłaThis thesis is a project that is conducted at Infinera located at Stockholm, Sweden. The project uses service design methodology alongside with user-centered design. The aim of the project isto examine and improve every day work lives of implementers of fiber optic networks. The current service is following a system-driven perspective. This project will examine ways to change this into a user-centered design perspective. Service design methods were used to investigate the service process and to gather insights. The project started with an initial preparation phase, followed by loop 1 and 2. Preparation phase was used to get a deeper understanding on fiber optic networks. Loop 1 and loop 2 included methods such as shadowing, a day in life, interviews and customer journey maps. These loop phases included interactions with the customers, the analysis of these interactions, ideation from these analysis and conceptualization. Five main problems were identified in the process. These were grouped into two as process related problems and user experience related problems. It is found out that the main reason behind process problems was lack of communication between departments in the company. These problems were project manager designation, lack of statement of work and the handover between sales department and technicians. The handover between sales department and technicians were selected as a next step to go on. Web applications were shaped as a concept to solve the problem that was selected. The project was finalized with suggestions on webapplications regarding the solutions of selected problems. The problems were identified related to the process. Sales to service handover was selected for further improvements. The generated concept on this problem was improved and presented to the company.

In the thirty years since the installation of the first fiber optic data link, data rates in installed fiber links have risen from a few Mb/s to tens of Gb/s. In the laboratory, data rates in a single optical fiber have already reached tens of Tb/s. These data rates greatly exceed electronic processing rates, so researchers have turned to all-optical signal processing to achieve many basic network tasks, like wavelength conversion, packet switching, and data regeneration. As data rates increase, the impairments caused by propagation through the glass of optical fiber become worse. Chromatic dispersion causes the temporal broadening of optical bits during propagation, leading to interference between neighboring bits. Nonlinear effects, like the nonlinear index of refraction and four-wave mixing, can cause interference between neighboring wavelength channels. The interaction of dispersion and nonlinearities can lead to variations in the timing of bits and the appearance of optical energy where there had been none. All these effects make 1-bits and 0-bits difficult to distinguish. Today, these distortions are overcome by electronic regenerators. Optical data streams are converted to electrical signals, processed electronically, converted back to an optical signal, and returned to the optical network. In this way, regenerators prevent the accumulation of noise and prevent noise from contributing to the production of more noise. The electronic solution is costly because of the extra hardware required for optical to electrical to optical conversions and performs poorly because of the losses incurred by those conversions. In this thesis, we investigate two regenerators that restore the data quality of ON/OFF keyed data without a conversion of the data to the electrical domain.
(cont..) Both regenerators are based on all-optical switches that take two inputs: the data pulses from the network, and a locally generated clock-pulse train. The all-optical switches then modulate the data pattern onto the clock-pulse train, which becomes the new data stream. The first switch we consider, the WMFUNI, uses the nonlinear properties of fiber to produce the switching action. Using the WMFUNI regenerator, we demonstrate the propagation of 10 Gb/s data over 20,000 km of commercial optical fiber. We also demonstrate the WMFUNI's ability to operate on 40-Gb/s data. Unfortunately, fiber has only a weak nonlinearity, so the WMFUNI is large (~40 cmx40 cm). The second switch uses the much stronger nonlinearity of a semiconductor optical amplifier (SOA). SOA-based switches can be integrated onto chip-scale optics. The switch we test, the SOA-MZI, fits on a ~0.5 cmxl cm chip. Using the SOA-MZI regenerator, we demonstrate the propagation of 10 Gb/s data over 10,000 km of commercial optical fiber. We also show in simulation that the SOA-MZI's operation may be extended to 40 Gb/s.
