Spools of fiber optic cable, containing various lengths of unclad fiber – sometimes as long as 200 km – are used in almost every lab where fiber optic networks and network equipment are tested. By connecting each end of the cable to the equipment, a mini “optical network” is created for testing purposes. A number of serious limitations exist with optical fiber spools. The most significant of these is that it is difficult and expensive to replicate the long distances found on actual wide area networks.
Network Delay Emulators from Anue Systems, Inc., provide a compelling alternative to test beds built with fiber spools. Anue Emulators can inject enormous amounts of delay, as well as many types of impairments, in order to model real world network behavior. Delays and errors can be added in a controllable and exact manner, with bit level granularity. The rich functionality, ease of use, and cost-effectiveness of Anue Network Emulators are causing many labs to select Anue instead of adding more fiber spools.
