“…Los operadores deben mantener la longitud de onda actual, de modo que haya una coexistencia con el actual GPON y las redes de acceso futuras. Sin embargo, en concordancia con [6]- [7], [16],GPON actual y XGPON en convivencia, requieren la separación de longitud de onda de las señales para evitar interferencias entre los canales descendentes y ascendentes.…”

Antecedentes: la información en un canal de fibra óptica sufre distorsiones debido a la aparición de efectos lineales y no lineales, restringiendo la velocidad de transmisión. En este documento se analiza el error no lineal denominado automodulación de fase (SPM),el cual genera un desfase en los pulsos trasmitidos, ocasionando errores de bits en la comunicación. Objetivo: el proyecto está orientado a evaluar el comportamiento del error no lineal SPM en una comunicación monocanal de fibra óptica utilizando Matlab. Métodos: su desarrollo parte del modelado matemático del error SPM, para ser codificado en Matlab y evaluar su desempeño en el canal para condiciones específicas. Para realizar las simulaciones se implementó un canal de comunicaciones en fibra óptica, teniendo en cuenta los parámetros que rigen las redes XGPON o 10GPON que son la siguiente generación de Red Óptica Pasiva con Capacidad de Gigabit (GPON). Para simular el canal de fibra óptica se definieron las distancias de 20, 40 y 60 km, y las potencias de 4, 10 y 20 mW, con velocidades de transmisión de 10 Gbps, en las longitudes de onda de 1550 y 1310 nm, usando la modulación QPSK. Los parámetros para desarrollar la simulación consideraron las recomendaciones de la Unión Internacional de Telecomunicaciones (ITU). Resultados: mediante un análisis gráfico se identificaron los parámetros que afectan el error SPM, como la potencia, el área efectiva, la distancia y el tipo de fibra, entre otros. Conclusión: el error SPM por sí solo no es perjudicial para las redes XGPON en la modulación QPSK, considerando que el máximo desfase obtenido en el proyecto fue de 28.8°, siempre y cuando se tengan en cuenta la potencia, la distancia y los tipos de fibra, de acuerdo con las recomendaciones de la ITU (G652, G987, G691 y G957). Palabras clave: Automodulación de fase, fibra óptica monomodo estándar, modulación por desplazamiento cuaternario de fase, red óptica pasiva con capacidad de gigabit.AbstractBackground: the information transmitted by optical fiber channels is distorted due to the appearance of linear and nonlinear effects, which restrict the transmission rate, this paper analyzes the nonlinear error selfphase modulation (SPM) Objective: the project aims to evaluate the behavior of nonlinear error SPM in a single channel fiber optic communication using Matlab. Methods: development of the mathematical modeling of error SPM to be coded in Matlab and evaluate their performance in the channel for specific conditions. To perform simulations a communications channel is implemented in fiber optics taking into account the parameters governing XGPON or 10GPON networks or which are the next generation of Gigabit Passive Optical Network (GPON). To perform simulations three distances 20, 40 and 60 km, and three power values of 4, 10 and 20 mW were defined, with transmission speeds of 10 Gbps wavelengths 1550 and 1310 nm, respectively; using QPSK modulation. The parameters to simulate were defined taking into account the recommendations of the International Telecommunication Union (ITU). Results: using a graphical analysis we identified the parameters that affect the error SPM, such as potency, the effective area, the distance, the fiber type, among others. Conclusion: the error SPM alone is not harmful to the GPON networks in QPSK modulation, considering that the maximum phase shift obtained in the project was 28.8°, provided that the power, the distance and the types of fiber are taken into account according to the recommendations of the ITU (G652, G987, G691 y G957).Keywords: Gigabit passive optical network, quaternary phase shift keying, self phase modulation, standar singlemode fiber.

“…In this way, wavelength-division multiplexing (WDM) can facilitate the integration of coding (FEC, trellis, turbo code, LDPC) with code modulation together in order to improve the spectrum efficiency and coding gain. These are the promising solutions for 5G network access with optical communications known as 10-Gigabit-capable passive optical networks (XG-PON) [7] that should coexist with GPON and WDM-PON networks, and also guaranteeing an optimal allocation of wavelength bands in order to avoid the undesirable interference of GPON with XG-PON.…”

Here, we propose a novel scheme based on advanced techniques of digital modulation in optical communications to achieve a single-channel transmission rate above 100 Gb/s. We utilize a hybrid scheme amplitude/phase/frequency/dual polarization, combined with multidimensional dual lattice and a low-density parity-check-coded modulation. The Stokes parameters are applied to the proposed scheme to map the fourdimensional classical polarization I X , Q X , I Y , Q Y in a threedimensional space. In addition, in the proposed system, the packing theory is applied to the bit interleaver process. Three wavelengths are packaged before being transmitted over a wavelength-division multiplexing optical channel. This modulation process is carried out using symmetrical geometric shapes, such as a hypercube or a polyhedron, based on the molecular links theory using a grouping of 12 and 13/15 bits for the cubic and spherical lattices, respectively. The proposed technique is evaluated in the context of long-distance communications over distances up to 100km. The bit error rate (BER) results showed that the optical signal-to-noise ratio was approximately 4dB over a distance of 50km. In addition, the power spectral efficiency was found to be 3 lambdas, which is considered good performance considering the effects of distance and the non-linear effects influencing the number of lambdas. Also, we use an optical time-division multiplexing scheme (OTDM) in order to achieve a transmission rate beyond 1Tbit/s, where the speed effect is evaluated, taking into consideration that the power spectral efficiency is degraded.

“…single data rate transmission furthermore only single or few WDM channels with various limitations decrease their effectiveness. However, few other techniques have been introduced for integrated standards such as coexistence of XGPON and NG-PON in [12,13] but they support up to 10Gbps only. Hence, these techniques are not suitable for future challenges.…”
