Title: Use of mode coupling optical fiber in communication system
Inventor: WHITE WHITNEY
IPC: H04B10/2581
Filed: 2000-09-13
Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber communication system such as an electric communication system and a data communication system. SOLUTION: A mode coupling plastic or glass optical fiber is used for transporting a light signal between a transmitter and a receiver in a communication system. For conquering the high attenuation characteristic of the mode coupling optical fiber incident power used for transmitting a signal on an optical link is normally higher than that used in a conventional compatible communication system depending on a standard signal mode or multimode glass optical fiber. For adapting to a larger incident power level, the communication system is designed with a receiver whose dynamic range is larger than that used in the conventional communication system.  Since the mode coupling optical fiber has the diameter of about 50 to 62.5 microns or a larger one, a comparatively simple and inexpensive butt connecting the fiber with the other system constitution elements (the transmitter and the receiver, for example) can be used.
