Reels of fiber are generally used to test fiberoptic components and compare various network archetectures. It is possible in this fashion to measure the bit-error rate, power penalty and other characteristics of a nominal fiberoptic link within the confines of a laboratory. However such measurements cannot easily be automated and practical considerations tend to limit the number of test cases. As a consequence stress testing, or pushing test conditions beyond the nominal case as well as the systematic measurement of design margins has not been widely available to designers of fiberoptic components and networks. Optical fiber emulators which replace reels of fiber with advanced electro-optical modules to produce a controllable amount of signal degradation address many of these issues. The design of such emulators presents many challenges which are discussed in this paper along with specific test cases.
