Abstract

A system for the bidirectional application of a dispersion compensating module in a regional system includes a dispersion compensating module configured to receive a first optical signal traveling along a first path and a second optical signal traveling along a second path, wherein the dispersion compensating module provides dispersion compensation to the first optical signal and the second optical signal. The system also includes a first circulator in optical communication with the dispersion compensating module and the first path, wherein the first circulator delivers the first optical signal to the dispersion compensating module. The system further includes a second circulator in optical communication with the dispersion compensating module and the second path, wherein the second circulator delivers the second optical signal to the dispersion compensating module. The first circulator is further in optical communication with the second path, receives the second optical signal from the dispersion compensating module, and transmits the second optical signal along the second path subsequent to dispersion compensation. The second circulator is further in optical communication with the first path, receives the first optical signal from the dispersion compensating module, and transmits the first optical signal along the first path subsequent to dispersion compensation.
