| 摘要 |
The transmission device includes an optical fibre (14) for linking at least one transmitter (20) and receiver (18). The transmitter and receiver are each directly associated with an optical working surface of the optical fibre, e.g. an optical fibre end face. The optical transmitter and optical receiver may be positioned next to one another. The transmitter may be incorporated in a central circular recess provided by the receiver. The receiver has a filter for filtering out the optical signals with the wavelength used by the transmitter. |
