Optical Connections to the Controller
A duplex fiber optic cable is used to interconnect the sensor and controller. The sensor
incorporates a 1.5m optical pigtail (or as specified by customer). If a longer connection to the
controller is required, then an extension fiber cable having duplex LC connector may be used.
Remove the dust cap form the connector on the cable and open the spring-loaded cover of
the receptacle on the controller. Insert the LC connector as shown. There should be a positive
click when the connector is engaged properly.
Do not force the Fiber Optic Connector!
Figure 7. Connecting Sensor to Controller Optical Interface
This is the same fiber used in local area networks (LANs). The cable ends must be terminated
with high quality Duplex LC connectors and meet these optical performance requirements:
•
Multimode Fiber 62.5/125µm, 0.275NA
•
Insertion loss <0.5dB,
•
Return loss >20dB
•
End-face geometry per TELCORDIA GR-326-CORE or equivalent
