“…In this case, each data rate is transmitted at a fraction of the serial data rate. 9 This method is suitable for short-distance point-to-point applications ͑few hundreds of meters͒ as the ribbon fiber is not cost-effective for lengths exceeding a kilometer. The initial intention of this application was to interconnect computer clusters, and high-bandwidth cross-connect and router systems.…”

Wavelength-division multiplexing (WDM) is a photonic technology that couples many optical channels (wavelengths) in a single fiber. Each wavelength represents a separate optical channel at a fixed bit rate. Thus, to increase the aggregate transportable bandwidth per fiber either the channel density must be increased or the bit rate per channel, or both. As a result, the signal quality for a given fiber length suffers due to the nonlinearity of the medium. Therefore, engineering and provisioning of WDM links to meet signal quality objectives is a complex task. Despite advancements in bit rate increase, not all applications require such high rates, as many applications require granularity finer than optical carrier n (OC-n) to increase efficiency. As a consequence, bandwidth efficiency, fine bit rate granularity, and diverse traffic type will be necessary characteristics of the next-generation WDM networks. We propose a WDM transmission method by which a highbandwidth-capacity wavelength bus supports many clients, more than the number of wavelengths, each at different rate and of different traffic type. In addition, the method uses low bit rates and cost-effective transceivers. We examine strategies to minimize linear and nonlinear impairments over a given span, strategies to enhance the quality of signal and increase the fiber span, and strategies to reduce cost of transported bandwidth-kilometer in a variety of dense WDM (DWDM) applications. We also examine the applicability of the method in various network topologies, and aspects of network protection and restoration. © 2004 Society of Photo-Optical Instrumentation Engineers.

“…At the transmitter section a pseudo-random bit sequence of a given length is used to modulate a laser source directly or externally through an amplitude or phase modulator. The optical fiber can be modeled using the Time Domain Split Step [2] method, effective to simulate long bit sequences needed for systems with strong inter-symbolic interference, or the Frequency Domain Split Step [3] method, effective to simulate wide-bandwidth occupancy CWDM systems. The Monte-Carlo and semi-analytical techniques can be used to model the noise generated by optical and electrical amplification.…”

Designing broadband access networks involves selecting the topology that satisfies the network requirements, and comparing the performance of different what-if scenarios in order to achieve the optimal network layout. Modeling software tools are instrumental for each phase of the design cycle and help answering to complex questions such as what is the impact of single-and multi-mode fiber linear and nonlinear effects, what is maximum fiber length before eye closure, how many regenerators are needed and where they have to be placed. This paper shows through a series of examples how modeling tools can be used for single-and multi-mode broadband access network design and planning.

“…In this section, we describe the multimode-fiber-link model. A detailed description of the signal propagation through the driver, the laser, and the receiver, as well as the in-depth discussion of the model and mode partition noise, can be found in [9] and [10]. For the sake of introducing the symbols and outlining the model capabilities, we give a brief description of the laser model.…”

This paper describes an advanced multimode-fiber-link model that was used to aid the development of Telecommunication Industry Association standard specifications for a next-generation 50m-core laser-optimized multimode fiber. The multimode-link model takes into account the interactions of the laser, the transmitter optical subassembly, and the fiber, as well as effects of connections and the receiver preamplifier. We present models for each of these components. Based on these models, we also develop an efficient and simple formalism for the calculation of the fiber transfer function and the signal at the link output in any link configuration. We demonstrate how the model may be used to develop specifications on transmitters and fibers that guarantee any desired level of performance.
