FiberPatrol FP1150 Product 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 activation 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 0.2)
Equipment requirements
For the FP1150 Series, the total length of fiber optic cable (sensor cable + lead cable > 500 m)
determines the required model of the sensor unit and the software activation license for the
FiberPatrol system. Specific FP1150 Series sensor units and software activation licenses are
available for cable lengths up to 5 km, and for cable lengths up to 40 km.
Other required equipment includes:
•
end modules (depending on configuration)
•
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)
Note
Each FP1150 SU supports up to 500 m of lead cable that does not
count against the per meter software activation license.
