Chapter 3 Reflectometry measurements
FTTA-SLM option
mainframe as a license key (see the 2000/4000 base-unit user manual for the instruc-
tions on license files installation).
FTTA-SLM simplifies OTDR testing for cell-tower technicians and eliminates complexi-
ties of result interpretation.
In a FTTA environment, the OTDR module, associated with the FTTA-SLM application,
allows to:
•
Characterize and measure the fiber link loss, measure the loss and reflectance of
each passive element, and provide the position for each one: Acceptance
Testing
•
Locate and identify causes of failure on a fiber link: Troubleshooting / Mainte-
nance.
Acceptance Testing
One way to judge installation quality is to use a loopback device (a retractible/expand-
able fiber leash cable or a patchcord) on duplex fiber to test at the junction box or RRU
location and shoot with an OTDR from the BBU or fiber-patch panel location to qualify
the entire fiber channel.
