Optisches Modul für ein optisches Übertragungssystem mit Hilfsträger-Multiplex |
摘要 |
An optical module for use in a subcarrier multiplexed (SCM) optical transmission system and capable of reducing the distortion of a signal light due to multiple reflections. A distortion reducing device is implemented by an optical fiber cable longer than the coherence length of the signal light and is located at each of signal input and output portions or each portion where optical devices are jointed together within the module. <IMAGE> |
