VERFAHREN ZUR ÜBERWACHUNG EINES OPTISCHEN WELLENLEITERS, ÜBERWACHUNGSVORRICHTUNG UND ÜBERWACHUNGSEINHEIT FÜR DAS VERFAHREN |
摘要 |
The invention concerns a Method for monitoring an optical waveguide between a monitoring terminal point (5) and a monitoring unit (3), in which an optical data signal (10) from a transmitter (1), and for amplification, pump light from a pump laser (3), is emitted into the optical waveguide, wherein a monitoring signal (51) transmitted by the monitoring unit (3) is returned via the same waveguide to the monitoring unit (3) by a reflection device located at the monitoring terminal point (5), in particular a Bragg grating placed in the optical waveguide, and wherein the reflection device is tuned to a reflection that is exactly the wavelength of the monitoring signal (51), as well as a monitoring system and a monitoring unit (3) for said Method. <IMAGE> |
