ABSTRACT
One of the major applications of single-mode fibers (SMFs) concerns telecommunications, particularly for trunk networks, where long-haul high-data-rate links predominate. Designing SMF transmission systems requires analysis of the possibilities and characteristics of all components. Such a set of transmission characteristics can be achieved with a variety of SMF designs. The transmitters basically involve a laser diode, together with its control and modulation circuitry, and optical coupling. Receivers involve basically a photodetector, together with its control and amplification circuitry, and optical coupling. The optical coupling can be achieved through a multimode optical fiber tail, which could reduce the loss on the receiving side. Basically, any medium capable of providing a strong chromatic dispersion in a rather compact form could serve as an optical pulse equalizer, provided that its chromatic dispersion is able to cancel that of the total fiber length.
