Abstract

Analyzes the switching characteristics of a single mode optical fiber. In the dispersion fiber not only is the switching signal delayed, but also the switching speed is limited. The formula for calculating the switching time (rise time or fall time) is given. The results show that the switching time is proportional to the square root of the absolute value of the fiber dispersion, and is proportional to the square root of the fiber length, too. In a 1 km G.652 optical fiber operating at 1.55 /spl mu/m, the switching time is about 7 ps. This time is the final limit for the switching speed of a switching element with two optical levers constructed by this kind of fiber.
