FIBER CHARACTERIZATION SCRIPT
GETTING STARTED
OBS-550 has HD mode which is High dynamic mode. By selecting HD mode, the EDFA amplifier built into the light source is
engaged and the output power increases substantially. In addition, the spectral range of the light source goes from 1460-
1640 to 1530–1565 nm.

The following procedure describes how to configure a T-BERD/MTS 8000 platform with a MTAU 4-port module and how to start the
Automated Fiber Characterization Script. Please read the entire procedure BEFORE starting.
Inspect and clean connectors
Before connecting a fiber into a test module, inspect and clean the module bulkhead and the fiber jumper connectors.
!- Use video inspection scope to verify the connector quality.
- Use appropriate cleaning material (e.g. IBC™ cleaner, cotton swab, dust air sprays, etc...).
Connecting the test modules to the MTAU
Connect the OTDR module to the MTAU port A with a jumper.

The test modules (OTDR, DISPAP and OFI) have to be located in the slots closest to the mainframe. Keep the MTAU and BBS
modules at the back slots.

Repeat step 1 and 4 for the second unit.
Referencing the Test Functions
The Insertion Loss (IL), the Optical return Loss (ORL), the Chromatic Dispersion (CD) and the Attenuation Profile (AP)
measurements have to be referenced before starting testing.

Check List
Check that OEO OTDR settings on each unit (for bidirectional solutions) are identical; or that SM OTDR settings on each unit
are identical. Note: You can press the Test Auto and Factory Defaults soft keys to get a set of default settings to work from.
Check that units are correctly set, typically Km.
Set the IL/ORL (FOX) wavelengths to be consistent with OTDR in case the OFI module is used.
Ensure that the Acquisition Band for CD and AP is appropriate to your Broadband Source. For handheld OBS 500/550 use
SCL; for BBS2A module use OESCL. When you switch acquisition band, you must check that a valid reference exists for that
band, the reference S/N should match the S/N of your source.
Check that Length is set to “Known Length” = Yes, for PMD, CD and AP testing. This will allow the Script to auto populate the
length field using the OTDR results.
Check that PMD, CD and AP Length units are consistent with OTDR settings.
Setup File Parameters
This paragraph provides a set of instructions for selecting typical File Storage options for Fiber Characterization test results.
Press the FILE Hard Key of the mainframe
Press softkey until the Setup radio button is selected. It is recommended you accomplish this on one of the OTDR tabs
(SM OTDR or OEO OTDR).
Select the following parameters starting from the top of the menu to the bottom.
a. Press the softkey
b. Select
c. For File type user preference, typically one OEO file or Single SOR files
After all the File parameters are selected, press , softkey
Select storage directory
Press the softkey once to select the “Explorer” page.
Using the navigation keys , on the left side of the screen, select the main or sub directory where you wish to store files,
typically the “Hard Disk”. After highlighting this Directory, press softkey to create a new subdirectory where you wish
your files to store.
It is not mandatory to create a subdirectory as the script automatically creates one at the start of the test sequence.
Use the pop-up keyboard to enter the directory name.
Move the pointer on the left to highlight the new directory so that files will store there.
Getting started with the “Link Characterization” Script
Press the hard key.
Drop down using the navigation keys or touch to select the “Link characterization” script.
Press the soft key to launch the script process.
Define the Test Setup
The available test functions are listed in black in window.
Check marked the square button for each test function to be added in the test sequence. (Button becoming red).
-: Available if video inspection scope is connected to the mainframe. The script will open up the connector
image viewer.
-: The script will use the wavelengths defined in the OTDR test Setup and measurements will be performed using Automatic
configuration.

-: Automated bi-directional OTDR measurement using the . It will require the use of the optical talk
set and will select automatically.
-: Automated bi-directional Loss test set, using the OFI module (Fox port).
-: Chromatic Dispersion measurement. It requires the use of the OBS handheld or the selection of the on the
other T-BERD 8000 script configuration menu.
-PMD measurement. It requires the use of the OBS handheld or the selection of the on the other T-BERD 800
script configuration menu.
-Attenuation Profile measurement. It requires the use of the OBS handheld or the selection of the on the other T-
BERD 8000 script configuration menu.
-It enables communication between 2 T-BERD 8000 running the script in order to perform bi-directional
OTDR measurement and automate the BBS mode selection.
Define the Job Type
The enables to define how the product is going to organize the results and what type of characterization test sequence is
performed.
Check marked the square button for each type (button becoming red).

-is used for testing an entire cable. The script will save all the test results and the summary report into one
directory, and for all the fibers. The directory will be created using the Cable ID as the name. This directory will be located under the
current selected directory. Make sure the selected directory is the root hard disk or a well known one. Press the System hard key
and the File hard key to get access to the Explorer in order to change the directory selection.
-is used for few fiber testing. The script will save the test results of one fiber and the report summary into one
directory. Each fiber will have its own directory. The directory will be created using the FiberID and the Fiber #, as the name. This
directory will be located under the current selected directory.
-defines the script sequence and synchronization between the 2x T-BERD 8000. It is required when
and/or test parameters are selected.
-defines the script sequence when only one T-BERD 8000 is used in conjunction with a handheld OBS 5x0 at the
far end.
Define the Link Description
The enables to document the information, related to the link being tested.
Fill-in all the information using the USB key board: Local Cable Id / Local Fiber Id / Origin & End Location / Job Ticket
-: select the expected bit rate in the drop down menu. This will pre-define the alarm thresholds for CD and PMD testing.
-Add a which will be loaded into each test application and save with each test results.
-Define the of your fiber under test.
a. Set the of the measurement between O->E and E->O (Origin and End).
b. If the Origin fiber number or cable Id is different from the far end, check mark in order to have
access to the local and distant information using the soft key.
Configuring the "Results" Summary table
This summary table enables to review selected values at the end of the test sequence. A pass/Fail status is associated to the table.
