LinkMap™with Pass/Fail
4
OTDR Software Options
M series OTDR LinkMap with Pass/Fail enables even novice users to easily and accurately
troubleshoot optical networks. LinkMap presents an icon-based view of the tested network clearly
identifying ber start, end, connectors, splices and macro-bends. A LinkMap Summary provides
end-to-end link length, loss, and ORL. Loss and reectance of detected events is compared to
industry-standard or user-settable pass/fail thresholds and displayed with clear pass/fail indications.
LinkMap feature is only available on M310 OTDR.
TruEvent™Event Analysis Technology
The M series OTDRs utilize AFL’s industry leading TruEvent technology to provide a new level of
accuracy and reliability in event analysis. Events on a ber include connectors, splices, optical
splitters and macro-bends. To accurately locate an event, OTDRs need to nd its location, identify
event type, measure reectivity and loss. M series OTDRs with TruEvent technology provide better
baseline documentation of ber links and enables the user to troubleshoot faulty networks more
effectively.
TRM (Test Results Manager) trace analysis and reporting PC Software
• A CD containing TRM 2.0 is included with every OTDR. The CD jacket has a sticker with a license
activation key for TRM Basic Software (OTDR Trace/OLTS viewer, Batch Editor, and Reports). The
activation key is good for up to ve fulllments to allow multiple PCs to run TRM 2.0 Basic.
The multiple fulllments also allows a user to activate TRM 2.0 Basic when changing to a new
PC. Once the ve fulllments have been used for a license key, the user must purchase a new
license, which will provide a new activation key good for ve fulllments.
• To install TRM Basic on additional PCs, additional licenses of TRM Basic Software may be
purchased by ordering part number TRM-00-0900PR.
• A single license version of TRM Advanced Software (incudes TRM Basic plus Advanced Analysis
for PC) may be purchased by ordering part number TRM-00-0910PR. TRM Advanced Software is
included in M310 OTDRs.
• To upgrade from TRM Basic to TRM Advanced software a single license version may be
purchased by ordering part number TRM-00-0920PR.
DFS1 Digital FiberScope
When a DFS1 hardware kit is ordered, the berscope can be plugged in M series OTDR and ready
for use.
This is a user’s guide for the M310 and M210e OTDRs. It assumes basic
knowledge in the use of an OTDR, OPM, and a PC.

Selecting Operating Mode from the Main Menu
Mode Description
Full Auto OTDR: This is the recommended mode for users who are not familiar
with OTDR operation. In the Full Auto mode, OTDR parameters such as Range, Pulse
Width, and Averaging Time are set automatically. Full Auto Tests are done at all
available wavelengths and always include an Event Table and Summary page. Pass/
Fail Thresholds are set to default with an option to be turned off.
Note: in the Expert mode, the Events Menu contains Event Threshold and Pass/Fail
Threshold Settings allowing users to change these settings and turn them on or off.
Expert OTDR: This mode provides the most setup exibility. Auto-Once will set
Pulse Width, Range, and Averaging time for one test and then return the OTDR to
manual mode. Auto will select the Pulse Width, Range and Averaging time for each
test. Manual allows users to set Range, Pulse Width, and Averaging Time manually.
Users can either enable event or disable the event table (Events = Auto / Off).
Note: in the Expert mode, the Events Menu contains Event Threshold and Pass/Fail
Threshold Settings allowing users to change these settings and turn them on or off.
Real-Time OTDR: This is the best mode for real-time troubleshooting. Note that the
Wavelength setting can only be set to individual wavelengths. The Range and Pulse
Width parameters are set by the user.
OPM: This mode is available to perform Optical Power Meter measurements.
DFS Test Mode is optional (see page 4 for details). When the DFS1 is
connected to an OTDR, this mode allows users to inspect ber optic connector end-
faces for damage or contamination.
OLS: This mode is available to turn on Optical Light Source using OTDR port.
OLS Test Mode is only available on M310.
Results: This mode provides le manager functions enabling users to open, review
and manage (cut/copy/paste/rename) stored results. Icons show the stored results for
each ber (OTDR, OPM, or end-face image).
Settings: This mode allows the user to adjust General Settings (Language, Distance
Units, Sounds, Auto Off function, Date/Time, Company Name, Keyboard Style) and
displays the OTDR version information.
New Job: This mode is available for creating new jobs (setting up a le structure
and dening the ber under test location: Drives, Folders, Jobs, Routes End Locations,
Cables, Test Equipment Location, and Operators).

Full Auto mode settings are common for all OTDR Test modes and will be referred to
as Core Settings.
Parameter Denition
Test Port This parameter indicates that a multimode or single-mode laser is used to
generate an OTDR trace.
Fiber Type This parameter is used to set ber type which determines the GIR and
Backscatter Coefcient.
Launch Cable
(Launch Cord)
This is a test cable used to connect the OTDR to the near end of the link
under test that is long enough to allow the OTDR to measure the loss of
the rst connection under test.
Receive Cable
(Tail Cord)
This is a test cable used to terminate the far end of the link under test that
is long enough for the OTDR to measure the loss of the last connection.

Width, Time, and Resolution for the rst
test. After test, returns user to OTDR Home
page in Manual mode, where user may
change any setting for next tests.
If set to Manual, you will need to set Range,

Expert Mode Settings: Setup - Manual (continued)
Real-Time Mode Settings
Note: The Range, Pulse Width, and Averaging Time parameters are user-selectable if the Setup
parameter is set to Manual.
Parameter Description
Range The Range parameter determines the distance range of the full (unzoomed)
trace. It also determines Resolution - the distance between data points in the
trace: the longer the range, the wider the data point spacing. We recommend
selecting the shortest distance range that is longer than the ber under test. For
example, to test a ber that is 1.5 km long (including launch and receive cables),
select the 2 km range. Available Range:
Wavelength (nm) Range Settings
MM 850, MM 1300 250 m to 30 km
SM 1310, SM 1550, 250 m to 240 km
Pulse
Width
The M-series OTDR can operate using different pulse widths. Short pulse widths
provide the shortest event and attenuation dead zones. Long pulse widths
provide the best event detection on long bers.
Averaging
Time
The Time parameter determines the duration of a timed test. Available time
settings: 5 • 10 • 30 • 60 • 90 • 180 sec.
Resolution The Resolution parameter may be set to “Normal” or “High”
“Normal” resolution averages a higher number of acquired trace data samples
than “High” resolution does in a given time frame by using a more coarse data-
spacing, providing increased dynamic range.
“High” resolution has closer data point spacing which may reduce the dynamic
range while improving dead zones.
In addition to Core Settings, the Real Time mode allows you to set the Wavelength, Range, Pulse
Width, and Resolution parameters.
