6.4 Wavelength Selection Touch the desired wavelength to test. Both wavelengths can be selected to perform a dual-wavelength test which can be helpful in locating macro bends in single mode cabling. When using a quad wavelength OTDR only one mode (multi-mode or singlemode) can be selected at a time. -
Page 16: Refractive Index And End Of Fiber (Eof) Threshold
6.5 Refractive Index and End of Fiber (EOF) Threshold The Refractive Index (RI) setting calibrates the OTDR so it measures the correct length of the fiber under test. The RI setting is a ratio of the speed of light in the fiber to the speed of light in a vacuum. -

Page 18: Averaging Time
6.8 Averaging Time Averaging time is the amount of time that the OTDR runs and captures data during the test. During the test, thousands of samples are taken and averaged together to reduce noise in the traces. Reduced noise will make it easier for the OTDR to detect low loss events such as fusion splices that may be obscured by noise when the averaging time is too short. - Page 19 as a a result the noise floor will be very high. It is recommended that high pulse widths be used to compensate for the lack of overaging and the increased noise floor. Low loss events such as high-quiality fusion splices are likely to not be visible in real-time mode, it it best used for detecting reflective events or high-loss fusion splices or splitters.
-
Page 20: Event Sensitivity
6.9 Event Sensitivity Controls the noise filter in the OTDR firmware that minimizes false events from being detected. Low = events must be very discernible from noise to be detected. Medium = some amount of noise can be in the trace and the firmware will still identify them. -
Page 21: Pulse Width
6.11 Pulse Width Pulse Width (PW) setting adjusts the amount of power the OTDR sends into the fiber with each pulse. Rather than adjusting the brightness of the laser, power is controlled by the amount of time the laser fires for each pulse. The higher the PW, the more energy is input into the fiber and the farther the OTDR can measure. - Page 22 Range vs. Pulse Width Not all pulse widths can be selected on all ranges because a short pulse cannot reach the end of very long fibers, and long pulses can be too long for short fibers. The table below shows the allowable pulse widths depending on the selected range.

7.3 Application Limits After the Cabling Limits page, there are several pages of application limits. Application limits are defined by the IEEE and provide the maximum loss and length for each Ethernet speed for a given fiber type and wavelength.

Page 30: Otdr Result Screens
Chapter 9 OTDR Operation 9.1 OTDR Result Screens There are three views for the OTDR results, they are; Schematic, Trace, and Event Table The first view displayed after the test is run is the OTDR Schematic. The Schematic view is a linear map of the events detected by the FiberMASTER software which are classified as Launch, Splice, Connector, End, and Link. -
Page 31: Otdr Schematic Screen
9.2 OTDR Schematic Screen The schematic screen appears when the OTDR test is finished running. The schematic is a series of icons that represents events that the OTDR has analyzed from the raw trace data which are presented in an easy to understand format. An event can be activated by either tapping on it directly, or by tapping the left/right arrows to cycle through the list of events on the link. - Page 32 OTDR Schematic End Event The End event is where the OTDR detects the end of the fiber as set of the EOF setting the OTDR Setup configuration (described below). The End event displays the total distance of the link which in this example is 474.4 meters, and the reflectance of the last connector which is -26.5 dB.
-
Page 33: Otdr Trace Screen
9.3 OTDR Trace Screen Trace mode provides a classical OTDR trace that the user must interpret to find events, section losses, faults and other conditions. The appearance of the trace highly depends on the pulse width and averaging time of the test. If the trace is noisy, or there no events shown on the schematic when events are expected, try increasing the pulse width by one level. - Page 34 Central control buttons Splice Zone Setting Toggle Active Cursor When pressed (red when active), Press to change which cursor is sets the position of the four active.

Page 38: Average Splice Loss
Chapter 10 Advanced OTDR Operation 10.1 Average Splice Loss The Average Splice Loss method is meant to be used on noisy traces when it is difficult to attain an LSA area that lays flat on the back scatter before and after the cursor. This method takes an average of the selected points before and after the active cursor and uses this average to make a good estimation of the event loss. - Page 39 Splice loss measurement zones The splice zones for Average and LSA measurements can be manually set in the Trace and Event Table modes. The process of setting the splice measurement zones involves positioning four cursors that define two zones. Cursor 1 and 2 define the zone to the left of the splice/connector. Cursor 3 and 4 define the zone to the right of the splice/connector.
- Page 40 Correct vs. Incorrect Splice Zone Setup Splice zones properly setup on each Splice cursor 3 is set on the reflection side of the event. The LSA lines are of the connector causing the LSA line flat on the back scatter before and on the right of the connector to not after the reflection of the connector.

Page 41: 2-Point Connector Measurements
10.4 2-Point Connector Measurements The 2-point measurement mode measures the total loss between cursors A and B, including the loss of all fiber, splices and connectors. This is a quick method of measuring the link loss using the OTDR trace mode. Care must be taken when using the 2-point mode to ensure the cursors are not placed on the slope of a reflective event or a noise dip/spike. -
Page 42: 2-Point Link Measurements
10.5 2-Point Link Measurements A quick way to check the link loss is to change to 2-point mode and set cursor A at the beginning of the link, just after the dead zone, and cursor B just before the end-of-fiber event. The 2-Point box will provide the loss of the total link (not including the first connector), including the two connectors and the splice in this example. -
Page 43: Slope / Orl Measurements
10.6 Slope / ORL Measurements The 2-point cursor mode can be used to measure the attenuation slope of a section of fiber. Slope is defined as the attenuation per kilometer (dB/km) of fiber. This measurement can be directly compared to the specifications of the installed cabling to check for installation stress or damage that may be causing high loss along the entire length of the cable, not just in one spot. -

Chapter 11 Video Inspection Probe 11.1 Video Inspection Probe Operation The video inspection probe allows magnified end-face inspection of fiber optic connectors check for contaminates or damage. Proper cleaning and end-face inspection is a critical practice each time a connector is plugged into a mating connection or piece of fiber optic equipment. Fiber optic connectors are physical contact, meaning the faces touch each other when mated. -

Page 53: Setting A Reference Value And Testing A Cable
12.5 Setting a Reference Value and Testing a Cable When testing a cabling link for dB loss, the starting power level going into the cable under test must be known, excluding the loss of any test jumpers. This process is known as setting a reference. Failure to set the reference will result in inaccurate loss readings. - Page 54 3. Disconnect jumper 1 from the power meter. Do not disconnect the jumper from the light source once the reference has been set. 4. Connect jumper between power meter jumper using coupler. The loss value shown here is the loss of jumper 2 and coupler. Ensure that the value is less than 0.75 dB.
