APPLICATION
To reduce workflow complexity and test the service-
activation ( Fig. 10 -3):
Since the service-activation phase is often performed by
subcontractors, they must provide test reports for each turn-up.
To control the service-activation reports, connect your OLP-88.
√ The OLP-88 is connected with the PON network ( “Preparing
the TruePON measurement” on page 32 ).
The ONU/ONT serial number to customer service contract is
displayed.
Links automatically the service-activation test results to ONT/
customer.
To perform a facilitates service recovery ( Fig. 10 -3):
To easily identify and localize a rogue ONU that degrades or
disables the service of other customers, connect your OLP-88.
√ The OLP-88 is connected with the PON network ( “Preparing
the TruePON measurement” on page 32 ).
The presence of a rogue/alien ONU/ONT is detected and a
message is displayed that the ONU is not compliant.
► To facilitates service recovery, isolate the faulty ONU/ONT and
replacing it in time.
To perform the automatic certification ( Fig. 10 -6, -7, -9):
To perform a power-level verification at a customer ONT,
connect the OLP-88 to certify the service specifications.
√ The OLP-88 is connected with the PON network ( “Preparing
the TruePON measurement” on page 32 ).
Pass or fail information for downstream and upstream PON
power level measurements (1310/1490 nm and 1550 nm) is
displayed.
With the PON-ID the pass/fail thresholds of the G-PON system
is automatically set.
To perform a fiber plant qualification ( Fig. 10 -4):
During the construction phase, the fiber plant is qualified: end-
to-end loss testing ensures that the fiber link complies with the
loss budget. To control the qualification several years later,
connect your OLP-88.
√ The OLP-88 is connected with the PON network ( “Preparing
the TruePON measurement” on page 32 ).
A real time in-service end-to-end loss measurement is
performed and the pass or fail information is displayed.
