Recently, wavelength division mulplexing (WDM) technology has been extensively studied, and various WDM-PON architectures have been proposed for next-generation passive optical network (PON). In this paper, we combine the TDM with WDM architecture to achieve high-speed, long-distance transmission. To reduce the cost of ONU, we achive the colorless ONU by placing a Reflective Semiconductor Optical Amplifier (RSOA) in the uplink transmission. We build the whole architecture to simulate the Hybrid WDM/TDM PON System in Optisystem and the experimental results prove that the architecture is feasible and reasonable.

This paper presents on the design of L-Band Multiwavelength laser for Hybrid Time Division Multiplexing/ Wavelength Division Multiplexing (TDM/WDM) Passive Optical Network (PON) application. In this design, an L-band Mulltiwavelength Laser is designed as the downstream signals for TDM/WDM PON. The downstream signals ranging from 1569.865 nm to 1581.973 nm with 100GHz spacing. The multiwavelength laser is designed using OptiSystem software and it is integrated into a TDM/WDM PON that is also designed using OptiSystem simulation software. By adapting multiwavelength fiber laser into a TDM/WDM network, a simple and low-cost downstream signal is proposed. From the simulation design, it is found that the proposed design is suitable to be used in TDM/WDM PON for up to 64 Optical Network Units (ONUs).

In this paper, the performance and feasibility of a hybrid wavelength division multiplexing/time division multiplexing passive optical network (WDM/TDM PON) system with 128 optical network units (ONUs) is analysed. In this system, triple play services (video, voice and data) are successfully communicated through a distance of up to 28 km. Moreover, we analysed and compared the performance of various modulation formats for different distances in the proposed hybrid WDM/TDM PON. NRZ rectangular emerged as the most appropriate modulation format for triple play transmission in the proposed hybrid PON.

An advanced electro-optic hybrid rotary joint (EOHRJ) has been developed in Phase II of an AF SBIR effort with Physical Optics Corporation (POC) to replace cable wrap structure for multi-channel rotation-to-fixed (RTF) signal transmission. The EOHRJ meets AFFTC and other range special needs with a generic, high performance, rotary joint solution. At the moment, we have successfully installed and tested the EOHRJ on our KTM tracker system with the following capabilities: 1) able to accommodate hundreds of transmission channels, including electrical power, control, feedback, and low-speed signals; 2) able to accommodate multiple channel, high data rate (over gigabits per second), and bi-directional signal transmission; 3) able to be reliable for harsh environmental operation, adaptive to stringent sized requirement, and accommodating existing electrical and mechanical interfaces. The completed EOHRJ contains three uniquely integrated functional rings. The first and the outmost one is power ring, which provides RTF transmission channels for over 50 high voltage and high current channels. The second and the middle one is low speed electrical signal ring, which provides RTF transmission for over hundred control, feedback, and low speed data signals. The third and the inmost one is optical fiber slip ring, which, incorporating with current advanced signal multiplexing technologies (either time division or wavelength division multiplexing ) is able to provide multiple channel, high data rate, and bi-directional signal transmission. At the moment, the prototype module of the tree-layer EOHRJ has been successfully assembled in Air Force’s tracker system, and is providing a satisfactory performance. This paper presents our joint work on this project.

In this study, a review of research literature has been carried out to investigate Hybrid Time and wavelength Division Multiplexing techniques with respect to reach, split ratio, and speed of the network. This was done to overcome challenges presented by Passive Optical Networks, such as the reach and the high split ratio. A comparison of different methods clarifies that Hybrid PassiveOptical Networks have a high power-budget that ensure efficient signal transmission. The Optisys software has been used to analyze the performance of the different techniques.

Recent advancements in internet services have brought attention to access networks to have their bandwidth increased as they represent the last hurdle to the customer. Emphasis is put on high bit-rate transmission, network reliability and survivability as ways to reduce operational costs and enhance network coverage, scalability to curb capital costs. Researchers are seeking at improving the optical access network concepts known as hybrid wavelength-division-multiplexed and time-division multiple access passive optical networks. The networks are designed to be beneficial for operators due to low capital and operating expenditures. The passive optical network comprises of a centralized optical line terminal (OLT), situated in the central office and a number of optical network units (ONUs) are positioned some distance away from the OLT at the user end. Due to the need for longer and unrepeated transmission distances and higher capacity transmission, Hybrid WDM/TDM Passive optical transport networks are primed to give the capacity needed to meet the exponentially exploding telecommunications traffic in a cost-reduced way and used in conjunction with appropriate hybrid amplifiers great results have been realised. In this thesis, a hybrid WDM/TDM PON with a split ratio of 128 ONUs in the absence of amplification is investigated and a maximum transmission distance of 28km realised. Similarly, a Hybrid WDM/TDM PON with various Hybrid Optical Amplifiers for mid-range amplification is simulated and the performance is compared on the basis of BER, Quality factor (Q), eye opening and the maximum reach. The hybrid amplifiers RA –EDFA and EDFA-RA, RA-SOA and SOA-RA and SOA-EDFA and EDFA-SOA are simulated and compared to each other. It is seen that the hybrid amplifier RA-EDFA provides the highest output quality factor of 6.25257 and least bit error rate of 2.00309 x 10-10 at 95 km. Thus, a hybrid WDM/TDM PON with a hybrid amplifier improves the reach by 67 km with an increased number of users up to 256.

This book presents an in-depth deliberation on optical networks in four parts, capturing the past, present, and ensuing developments in the field. Part I has two chapters presenting an overview of optical networks and the enabling technologies. Part II has three chapters dealing with the single-wavelength optical networks: optical LANs/MANs, optical access networks using passive optical network architecture, SONET/SDH, optical transport network and resilient packet ring. Part III consists of four chapters on WDM-based optical networks, including WDM-based local/metropolitan networks (LANs/MANs) using single and multihop architectures over passive-star couplers, WDM/TWDM access networks as an extension of PONs with WDM transmission, WDM metro ring networks covering circuit-switched (using point-to-point WDM and wavelength-routed transmission) plus packet-switched architectures and WDM long-haul backbone networks presenting the offline and online design methodologies using wavelength-routed transmission. Part IV deals with some selected topics in six chapters. The first deals with transmission impairments and power-consumption issues in optical networks, while the next three chapters deal with the survivable optical networks, network control and management techniques, including GMPLS, ASON, and SDN/SDON, and datacenter networks using electrical, optical, and hybrid switching techniques. The final two chapters present elastic optical networks using flexible grid for better utilization of the optical-fiber spectrum and optical packet and burst-switched networks. The three appendices present the basics of the linear programming techniques, noise processes encountered in the optical communication systems, and the fundamentals of queuing theory and its applications in telecommunication networks.

With the emerging applications and needs of ever increasing bandwidth, it is anticipated that the Next-Generation Passive Optical Network (NG-PON) with much higher bandwidth is a natural path forward to satisfy these demands and for network operators to develop valuable access networks. NG-PON systems present optical access infrastructures to support various applications of many service providers. Therefore, some general requirements for NG-PON networks are characterized and specified. Hybrid Passive Optical Networks (HPON) present a necessary phase of the future transition between PON classes with TDM or WDM multiplexing techniques utilized on the optical transmission medium – the optical fiber. Therefore, some specific requirements for HPON networks are characterized and presented. For developing hybrid passive optical networks, there exist various architectures and directions. They are also specified with emphasis on their basic characteristics and distinctions. Finally, the HPON network configurator as the interactive software tool is introduced in this chapter. Its main aim is helping users, professional workers, network operators and system analysts to design, configure, analyze, and compare various variations of possible hybrid passive optical networks. Some of the executed analysis is presented in detail.
