• “Principle” on page 6
• “Initial setting of the reference trace” on page 6
• “Change the reference trace” on page 9
• “Momentarily stop the monitoring” on page 11

7OTU80091 Rev. 002 5

Chapter 2 Fiber Monitoring
Principle

Principle
The monitoring is based on comparison between a reference acquisition and the
current acquisition.

The reference trace is composed of two acquisitions (these dual acquisitions is called
SmartAcq):
– An acquisition using a short pulse to minimize the front end dead zone
– An acquisition using an appropriate setting to cover the whole fiber or user's
acquisition parameters

NOTE
After an upgrade from a software release that did not support "SmartAcq", SmartAcq
can be enabled by executing the command "OTU:TOPAZ:MON:MOD HIGH" in
Maintenance Window. Links will need to be deleted and re-created to be monitored
with SmartAcq.

A first marker is placed after the front end dead zone and a last marker is placed at the
end of the trace.

If a fault occurs before the first marker, it is classified "injection fault".

The deviations between the reference and the actual trace are compared against
threshold.

If a threshold is crossed, an alarm is generated with a severity according to the type of

level (minor, major, critical) which is crossed.

NOTE
For legacy monitoring principle, refer to “Appendix A” on page 57.

Initial setting of the reference trace

To set up the reference trace, from the monitoring view window:
1 Select the switch port
2 Click on Monitoring setup.
A pop up window is displayed that proposes to setup the OTDR parameters auto-
matically (Click on Manual to change it).
3 Click on Start to start the OTDR acquisition.

Initial setting of the reference trace

Figure 4 OTDR setup

After the OTDR acquisition is completed, it is displayed with the 2 markers automati-
cally positioned.

Figure 5 OTDR acquisition

If desired the markers can be moved. Click on open menu button at the right top
corner of the trace then click on .

Figure 6 Moving a marker

The name given to the monitored fiber can be changed. By default it is set to Link
followed by the switch port number (Ex: Link 2 for Port 2)

7OTU80091 Rev. 002 7

Chapter 2 Fiber Monitoring
Initial setting of the reference trace

The thresholds can be changed by setting the major and minor thresholds

Once the change is made click on Save on the top right of the window.

Change the reference trace

NOTE on DWDM Measurement Setup

With DWDM, monitoring principle doesn’t change, only the measurement Setup dif-
fers: you have to select the DWDM canal instead of the wavelength.
Figure 8 DWDM Setup

canal selection

Once the measurement ends, the OTDR trace displays for the corresponding canal.
Figure 9 DWDM acquisition

Then, proceed as described previously.

Change the reference trace

After the fiber is modified (repair, connection change) the reference trace must be modi-
fied to match the latest fiber change.

From the monitoring view window, click on the fiber name to display the current refer-
ence trace.

7OTU80091 Rev. 002 9

Chapter 2 Fiber Monitoring
Change the reference trace

Figure 10 Reference Trace

On the right top of the window click on Change reference. The

current reference trace can be replaced by a new measurement

After the new trace is displayed in dark blue, the change needs to be confirmed:

Figure 11 Change reference trace confirmation

After it is confirmed, click on Save to finish the reference trace change.

If the change is not confirmed, additional OTDR traces can be

displayed from the button Add trace. Among the displayed
trace, the reference trace is selected with the button Reference
trace.

Momentarily stop the monitoring

Momentarily stop the monitoring

To stop the monitoring, from the monitoring view window,:
1 Click on the fiber name to display the current reference trace
2 Click on Edit
3 Unmark Scheduled parameter.
4 Click on Save to register the modifications.

Figure 12 Monitoring Stop

In the monitoring view the column Monitored is unmarked when the scheduling is
stopped.

Prohibit OTDR measurements

When technicians work on the fiber, it may be safer to prohibit all the measurement on
the fiber to prevent eye damage with the OTDR laser.

Figure 13 Prohibit OTDR measurements

To prevent the measurements (monitoring or manual) on a fiber, from the Monitoring

view window, click on the fiber Name to display the current reference trace, then click
on Edit and unmark Measurement allow. Click on Save to register the modifications.

In consequence:
– In the monitoring view the column Monitored is unmarked when the measure-
ment is blocked.
– The button OTDR trace measurement is not displayed from OTDR trace
window
– The button Test now is not available from the monitoring view

View of the latest monitoring cycle trace

View of the latest monitoring cycle trace

The OTDR trace obtained from the latest monitoring test is kept. It can be displayed by
clicking on the Latest monitoring timestamp from the Monitoring view window.

Figure 14 Latest monitoring test - OTDR trace

It is useful to check the current trace after a repair or to understand why an alarm is not
cleared.

Test a fiber immediately

To short cut the monitoring cycle:
1 Select the switch Port to be tested.
2 Click on Test now button

Figure 15 Test a fiber

A short acquisition is included in the reference acquisition to monitor the beginning of
the fiber.

High Sensitivity Monitoring

Peak positions can move because of environmental effect (temperature) or

network change (patch cord change). The two options below define how to
manage this change.
– "Acceptable peak shift" defines the tolerance of peak position change
– "peak shift compensation" adjusts the peak position automatically if it has not
moved more than the acceptable shift. The latest peak position becomes the
reference.
4 Select one peak on the table to define the name and a threshold for this peak and
select the Monitored parameter.

5 Configure the threshold, in dB.

Default values: 1 dB for minor / 3 dB for major
6 Click on the right button and select Advanced configura-
tion to manually define the hysteresis; if not selected the
hysteresis is calculated automatically (0.2 dB).

NOTE

This function is available with an OTDR D Module and the High Sensitivity license.

The aim of this function is to detect faults of 0.1 dB or less.

tivity.
A pop up window is displayed that proposes to setup the OTDR parameters auto-
matically (Click on Manual to change it).

Chapter 6 Alarm Geo localization

A kml file containing an unique geographical route can be associated to a SmartOTU

port. The route must be made of an unique kml polyline "linestring" and not composed
of different polylines.

That kml file can be generated from any geographical system supporting this format
(Legacy GIS, Google Earth, mapinfo, etc).

CAUTION
There must be only one route in the kml file.

CAUTION
The origin of the route in the kml file must be set at the SmartOTU location.

Topics discussed in this chapter are as follows:

• “Associating a kml file to a port” on page 32
• “Displaying the alarm on a map or in the kml file” on page 32

Legacy monitoring principle

Legacy monitoring principle

These measurements are based on two markers: A first marker placed when the trace
starts to be linear and a last marker placed at the end of the trace. The level of the 1st
marker gives the level at the network input. The difference between the levels of the two
markers gives the optical budget of the fiber.

The measurement deviation between the reference and the actual trace is compared
against threshold. If a threshold is crossed, an alarm is generated with a severity
according to the type of level (minor, major, critical) which is crossed.
