DL-422/13-SM-ST-L
RS422<>Singlemode fiber optic
The fiber optic systems DL422 connect applications with a RS422 interface via Singlemode fiber optics with ST connector.
This innovative system allows creating optical point to point and bus structures.
The ruggedness to electrical and magnetic interferences, the potential separation of transmitter and receiver as well as ranges up to 40km between two fiber optic systems are important performance features of the transmission with POF, HCS and multimode or singlemode fiber optics.
LEDs and potential free contacts of a differential relay signalize defective states.
The fiber optic systems DL422 connect applications with a RS422 interface via fiber optics.
With the help of this innovative system optical bus, star, tree and mixed structures are possible.
LEDs and potential-free contacts (optional) of a fault detector relay are able to signal defective states.
FiberView option
FiberView is a monitoring system that has especially been developed to monitor the status of fiber optic paths. It consists of a software/hardware combination which is integrated in all active network components and which permanently monitors the path's budget per port. Three LEDs or - in case of switches - an additional user interface, reachable via web interface, show in terms of a "traffic light" if the fiber has got a good signal level (green LED), if the signal is close to the allowed limit (yellow LED) or insufficient (red LED). if the yellow LEDs lights up the budget is barely within the defined system reserve of 3dB. Since this warning level is additionally signalled via a potential free relay contact, it can be evaluated centrally in SCADA-systems as well.
In contrast to other status signals that have to be interpreted first, the FiberView "traffic-light" system is clear and generally understandable. Furthermore, the yellow phase allows a foresighted action, i.e. acting instead of reacting. Since the attenuation is not that high at this stage, the fiber optic connection is still working. Maintenance and repair work should, however, be initiated to prevent any breakdowns. Thus equipments' downtimes are avoided. All in all, a monitoring system like FiberView helps increasing productivity and reducing costs.
