End module
The end module terminates the laser light signal at the end of each sensor fiber, without causing
undesirable reflections. There are 3 types of end modules available, a single end module
(FPMA0212) a double end module (FPMA0222) and a double end module that is included in the
fiber connection module (FPMA0922). The end module can be located outdoors in a splice
enclosure or indoors in the fiber connection module. The location of the end module depends on
the sensor cable configuration.
Sensor cable/non-detecting lead cable
FiberPatrol sensor cable is telecommunication grade single-mode fiber optic cable with a medium
density polyethylene outer jacket and a waterblock system. The non-armored loose tube cable is
comprised of a 5 unit fiber optic core (12-fiber buffer tubes and PE filler units) a central strength
member and a rip cord. Sensor cable can be ordered in lengths of up to approximately 12 km
(7.5 mi.) with 12, 24, 36, or 48 fibers. However, to facilitate transportation and on-site installation,
maximum reel lengths of 5 km (3.1 mi.) are recommended. The non-detecting lead cable is
identical to the sensor cable, with detection sensitivity being controlled via software. For sites that
require additional protection against vandalism, armored sensor cable is available (see
