Sensor cable terminations
Each sensor fiber must be spliced to an end module to terminate the detecting sensor cable at the
ends of S1 and S2. At the end point, the sensor cable requires a 10 m (33 ft.) service loop to
provide access to the sensor cable and splice enclosure. The fusion splices at the fiber connection
module and end module are made after the sensor cable has passed the OTDR measurement
tests from both ends of the cable.
Figure 46
shows the recommended installation of an end
module.
Figure 47
shows the recommended installation of two end modules for contiguous
FiberPatrol sensors. In the example for the contiguous sensors, a short length of sensor cable is
used to splice the dark fibers that are required from one sensor system to the next.
