FiberPatrol Site Planning & Installation Guide
Service loops
Service loops provide extra sensor cable for making future repairs, and for making fusion splices
to access the dark fibers in the sensor cable. A 10 m (33 ft.) service loop is recommended for
every 300 m (984 ft.) of installed sensor cable. A 10 m service loop is also recommended on the
hinged side of each gate that is protected by sensor cable. A 10 m service loop is typically
comprised of 5 loops of cable with a 60 cm (2 ft.) diameter. In addition, a 10 m (33 ft.) splice point
service loop is required for each section of sensor cable at all splice enclosure locations. Service
loops must be securely attached to the lower section of the fence beside a fence post. Attach
service loops directly to the fence fabric using one cable tie at each 45º point of the loop (8 cable
ties).
