Radio Over Fiber-Based Wavelength Division Multiplexed/Time Division Multiplexed Passive Optical Network Architecture Employing Mutual Injection Locked Fabry-Perot Laser Diodes
摘要： We demonstrate a radio-over-fiber-based hybrid wavelength-division-multiplexed/time division multiplexed passive optical network (PON) to transmit 5 Gbps data rate to serve 32 subscribers. A broadband light source (BLS) is realized by mutual injection locking between two Fabry-Perot laser diodes at the transmission section to seed wavelength-division-multiplexed channels. Mutual injection locking technique is used to enhance the performance over single Fabry-Perot laser diode and 15 dB/Hz improvements in relative intensity noise(RIN) is realized in our proposed network system. All-optical up-conversion of a 10-GHz 1.25 Gbps on off keying radio frequency (RF) signal is achieved using one single-arm Mach-Zehnder modulator (MZM). Transmission performance over 25-km single mode fiber is investigated. Low bit error rate with enhanced eye-diagram is obtained in our proposed system. As a result, the radio over fiber (ROF)-based wavelength-division-multiplexed/time division multiplexed PON set up employing mutually injection locked Fabry-Perot laser diodes can be a better choice in high speed long-haul optical communication system.

摘要： Continuous growth of data tra?c in optical access networks is driving the increase of utilized data rates even up to 25 Gbit/s per wavelength. While due to utilization of signals with large electrical bandwidth, requirements on the bandwidth of electrical and electro-optical components increase signi?cantly. Addressing that, the feasibility of application of the minimal transmitter and receiver bandwidth has received considerable attention. In this research, via numerical simulation in VPI Photonics Design Suite software we evaluate the impact of the shape of MZM frequency response based on amplitude frequency response (S21) from commercial MZM speci?cation. Moreover, addressing the requirements on numerical simulation models that ensure simulation of MZM frequency response curve for prediction of the overall system performance, we have also evaluated several analytical frequency responses (corresponding to the responses of 1 and 4-pole, Bessel and Gaussian ?lters) with di?erent 3-dB bandwidth values. Based on the obtained results, we propose the approach for the simulation of MZM frequency response that is the most relevant for our utilized PAM-4 modulated WDM-PON system with 25 Gbit/s bitrate per channel.

摘要： Third generation fiber-to-the-x (FTTx) will introduce wavelength division multiplexing (WDM) technology to increase data rates up to 40 Gbit/s, as well as coexist with current communication systems. WDM passive optical network (WDM-PON) based fiber-to-the-home (FTTH) system architecture together with the Next-generation passive optical network (NG-PON) can provide solution related to nowadays problems with transmission capacity. It is expected that NG-PON systems will become more cost-efficient at high per user data rates, providing different transmission speeds for end users, based on pay-as-you-grow approach. In this paper, our introduced system model is used to obtain WDM-PON system effectiveness for different data rates of up to 32 Gbit/s per downstream transmission channel. We created combined simulative-experimental WDM-PON transmission system model in environment of RSoft OptSim simulation software to compare the performance of non-return-to-zero (NRZ) on-off-keying (OOK) modulated PON transmission system versus transmission bitrate and distance. Results showed that proposed transmission system is capable to provide data transmission of up to 32 Gbit/s per channel with BER < 10?3, if additional forward error correction (FEC) is used. Additionally, to increase the reach of investigated system, fiber Bragg grating-based dispersion compensation module (FBG-DCM) is implemented, therefore enabling full pre-compensation of chromatic dispersion.

摘要： In this paper, the architecture of hybrid analog radio over fiber (ARoF) and next-generation (NG) wavelength division multiplexed passive optical network (WDM-PON) infrastructure for broadband internet services and the latest fifth-generation (5G) cellular mobile communications is proposed. Investigated ARoF-WDM PON architecture is a trade-off between technology and cost for future 5G mobile cellular communications to meet the internet service requirements, allowing to increase system capacity ensuring higher spectral and energy efficiency. In our proposed infrastructure the widespread used passive optical access network (PON) architecture is technologically transformed to the AROF-WDM-PON transmission system without replacing existing network elements, by integrating baseband units (BBUs) or mobile radio transmitters located in optical line terminal (OLT) at the central office (CO) and the receiving radio unit (RU) part of mobile base stations, leaving the traditional WDM-PON broadband architecture unchanged. In our investigated ARoF-WDM PON transmission system model, designed in the simulation environment, we research the possible ARoF system implementation scenarios into the PON’s segment, which has been now standardized to the 40 Gigabit-capable next-generation passive optical network (NG-PON2) standard providing an unique solution for hybrid fiber optical infrastructure serving as the next step for future 5G wireless communication networks.

摘要： Access network is that part of telecommunication system which connects multiple subscribers to the service provider. Currently deployed access networks mostly make use of copper cables like a twisted pair or a coaxial cable [1]. It seems, however, that they do not provide sufficient data rates to fulfil continuously increasing needs for broadband telecommunication services. One of the most promising approaches for providing high-speed, all-optical, symmetric transmission of digital signals are passive optical networks using the wavelength division multiplexing technique (WDM-PON) [2]. WDM-PON access systems can offer large capacity, high transmission rate and data security. On the other hand, they require low-cost, highly reliable devices of high overall performance. It seems that the photonic integration technology based on indium phosphide is a platform of choice to meet these requirements, as it enables fabrication of compact, reliable and energy efficient devices in a form of monolithic chips, comprising multiple active and passive components. InP-based photonic circuits can provide the functionality of light generation, propagation, modulation and detection for optical signals of wavelengths around 1550 nm.

摘要： Brazilian researchers have been active since the very early days of microwave-photonics, even before this term was coined. The present paper addresses current research, focusing mostly on the activities conducted at the University of Sao Paulo and the National Institute of Telecommunications (Inatel). From a device-level point of view, we demonstrate a variety of photonics-assisted RF devices including frequency converters, amplifiers and RF front-ends. Regarding microwave signal distribution, we demonstrate both a multi-band optical-wireless network delivering 3 Gb/s at 26 GHz as well as a colorless WDM-PON architecture, based on the self-seeding and wavelength-reuse techniques, as an future alternative for 5G radio-over-fiber fronthaul.

摘要： Optical fiber cable has been presented as a solution to high bandwidth demand. A bidirectional WDM-PON (wavelength division multiplexed-passive optical network) with FTTx (fiber to the x, where x=home, hospital, business, school, mall, etc.) model has been presented with EDFA, WDM mux-demux splitter and APD photo detector for long haul transmission system and as a solution to last mile problem. The proposed model has been designed for 3 Gbps non-return to zero (NRZ) transmission system over 30 km long bidirectional optical fiber. The proposed model is applied on Coarse Wavelength Division Multiplexing (CWDM). Further, it has also been compared with the existing reported work on the basis of quality factor, BER and eye diagrams. The proposed model enhances the performance in terms of bit error rate and quality factor at the downstream and upstream end of the systems.
