| 摘要 |
The invention inter alia relates to a method of receiving an optical-duo-binary, ODB, signal (S), which has a predefined ODB-transmission bit-rate (B), using a photoreceiver, said method comprising the step of filtering the ODB signal using a filter (10) which provides a frequency peak in the photoreceiver's frequency response located in the spectral range between 30% and 70% of the predefined ODB-transmission bit-rate. |
