Maximizing Optical Power Throughput in Long Fiber Optic Links

Noise in Fiber Optic Communication Links

The physics of noise in optical communication links is of great interest in the design of fiber optic communication systems. In this report the role of noise in optical communications, and how it can limit the performance of optical communications systems, will be examined. The origins of noise in the various optical and analog electronic components will be discussed, and a methodology for a “n...

A Study of Broadband Microwave Fiber Optic Links with Linearized Integrated-Optic Modulators

A universally accepted figure of merit for analog microwave transmission links is the spur-free dynamic range (SFDR), which is the ratio (usually expressed in dB) of the largest to smallest signal a link can transmit and receive without introducing any measurable distortion. This paper presents the result of a study of broadband, microwave fiber optic links that contain high-linearity integrate...

Designing Fiber Optic Systems

Lasers and LEDS Electrical to optical video converters generally have a BNC coaxial cable connector at the input and a fiber optic connector on the output. In order to get the digital bits down the fiber optic cable, a light emitting device is used, onto which the digital signal is modulated. Either a laser or an LED (Light Emitting Diode) is used for this purpose. Lasers are more expensive, bu...

Integrated Transversal Equalizers in High-Speed Fiber-Optic Systems

Intersymbol interference (ISI) caused by intermodal dispersion in multimode fibers is the major limiting factor in the achievable data rate or transmission distance in high-speed multimode fiber-optic links for local area networks applications. Compared with optical-domain and other electrical-domain dispersion compensation methods, equalization with transversal filters based on distributed cir...
