| 摘要 |
A bidirectional chromatic dispersion system includes an optical circulator that includes four ports (33). A first port (35) is coupled to a first optical transmission medium (43) and a third port (39) is coupled to the second transmission medium (45). A first dispersion compensating grating (49) which reflects wavelengths in a first optical band is coupled to the second port through a dispersion compensating fiber, and a second dispersion compensating grating (47) which reflects wavelengths in a second optical band is coupled to the forth port through a dispersion compensating fiber. The first dispersion compensating grating is substantially transparent to wavelengths in the second optical band and the second dispersion compensating grating is substantially transparent to wavelengths in the first optical band.
