Bi-directional Optical Recirculating Loop for Multi Channel WDM Applications
Project Award Date: 02-01-1999
Optical fiber recirculating loop has been used widely in fiber optical communication labs. It is a very important way to evaluate transmission performance of both ultra long distance submarine fiber-optic systems and wideband terrestrial fiber-optic systems without actually using many spans of fibers and optical amplifiers. To date, all of the optical fiber recirculating loop test beds were designed for unidirectional operation. To evaluate transmission performance of bi-directional optical systems, the development of a bi-directional, fiber-optic recirculating loop test bed is indispensable.
We investigate and optimize the configurations of bi-directional, fiber-optic recirculating loops to construct a well packaged, user-friendly, bi-directional loop test fundation that can be used in high-speed bi-directional SONET/SDH fiber-optic transmission experiments.
