Wavelength agile optical transponder for bi-directional, single fiber WDM system testing |
摘要 |
A wavelength agile optical transponder system and method for testing a fiber optic link formed of a single fiber. An optical source coupled to the optic link provides a signal at a first wavelength which is propagated towards a wavelength division multiplex (WDM) coupler disposed on the optic link. Upon receiving the optical signal by a receiver, an optical cross-connect arrangement is utilized for transmitting the optical signal after translating its wavelength into a second wavelength. By evaluating the optical signal in the optical loop-back thus effectuated, the path integrity of the optic link is determined without having to know the wavelength of the incident signal or direction of transmission.
