FiberPatrol FP1150 Product Guide
FiberPatrol splices
FiberPatrol sensor cable requires high quality fusion splices in the equipment room, as well as at
any outdoor field splice locations including fiber termination at end modules. All splices are made
in a splice tray which is installed either in the 1 RU fiber connection module for equipment room
splices, or in an outdoor rated splice enclosure for field splices. All fiber splices must be tested and
verified with an OTDR (typical results range from 0.01 to 0.03 dB loss per splice; maximum
allowable loss per event is 0.1 dB).
shows a splice tray and a dual end module. The
equipment room and end module fiber splices are identified in the following table.

CAUTION
The FiberPatrol sensor unit and patch cables include protective dust caps
on the connectors. Leave the dust caps in place until you make the
connections. Do not touch the ends of the fiber connectors or allow the
ends of the fiber connectors to touch anything. To make the connection,
remove the dust cap, thoroughly clean the connector ends, and then
gently insert the FC/APC connector and tighten until finger-tight.
Note
The loss at splices must not cause the average loss of the sensor cable
to exceed 0.25 dB/km (40 km/side), or 0.24 dB/km (50 km/side, TPI) as
measured by the OTDR.
