FiberPatrol Site Planning & Installation Guide
Cable requirements
Calculating the total length of fiber optic cable required is one of the most important parts of site
planning. Other equipment requirements, including the necessary software license, are
determined by the length of cable. The following table provides guidelines on how to determine
how much cable is required. Alternately, the length of cable required can be estimated by the
following formula:
(lead cable length) + (length of protected fence) + (length of protected fence X 0.15)
Equipment requirements
For the FP1150 Series, the total length of fiber optic cable (sensor cable + lead cable) determines
the required model of the sensor unit and the software license for the FiberPatrol system. Specific
FP1150 Series software licenses are available for cable lengths of 1 km, 2 km, 3 km, 4 km, 5 km,
9 km, 12 km, 16 km, 20 km, and 25 km.
Other required equipment includes:
•
one dual or two single end modules
•
1RU rack-mount fiber connection module (for equipment room fiber splices)
•
1RU rack-mount keyboard monitor mouse (optional, for equipment room access to SU)
•
outdoor splice enclosure (1 required for each outdoor cable splice, or termination)
•
splice consumables kit (each kit includes the components for 24 splices)
•
cable management kit (1 required per swinging gate panel for each protected gate)
•
stainless steel cable ties, or UV resistant plastic cable ties (1 tie per 50 cm [20 in.] of cable,
additional ties required for cable loops and outdoor splice enclosures, stainless steel cable ties
require an installation tool)
•
FiberPatrol cable vaults (optional) for buried isolation loops
•
conduit for below ground cable bypasses
Feature
Description
(length unit = meters, single pass coverage)
Cable length
lead cable
distance from equipment room to start of perimeter
perimeter length
length of protected fence including gates and bypasses
gate coverage
length of cable required to protect, and/or bypass, all gates
service loops
(protected fence length divided by 300 m + number of
service loops for gates + number of cable sections going into
splice encl equipment room service loop) X 10 m
isolation loops
number of isolation loops X 13 m
sensitivity loops (1) number of corner posts and heavy gauge tension/support
posts X 3(fence height - 60 cm)
sensitivity loops (2) (number of heavy posts at gate/obstacle locations) X 2(fence
height - 60 cm)
cable overage
calculated length of cable (above 7 features) X 1.15 (for 15%
overage)
cable requirement
sum of the above 8 features = total cable requirement
Note
For FP1150 systems using the split configuration, the model and
software licenses support twice the cable length, as listed above.
