Optical supervision of ring marking of optical fibers

The monitoring of ring marking (RMS) optically detects the presence of ring marks on optical fibres during the ring marking process and automatically checks whether the ring marks detected match the ring marking impulses triggered by the ring marking control system. This is a dependable method of detecting badly applied or missing ring marks. The occurrence of these errors is statistically recorded and an suitable alarm set off when an adjustable tolerance threshold is exceeded. This guarantees safe, fault-free production.
