摘要 |
The invention refers to an optical fibre transmission line which comprises means (9, 10) for injecting and means (9, 10) for extracting optical service signals from the line' s optical fibre (3), where said means comprise emission and/or reception units (10) of optical service signals, suitable for receiving from the optical line (3) and/or emitting towards the line itself service signals in the form of optical signals having a wavelength which is substantially different from the wavelength of the telecommunications signals, each of which units (10) is associated with a corresponding optical coupler (9) inserted along the line (3), suitable for coupling within the line fibre and/or for extracting from it the optical service signals. <IMAGE> |
