Chapter 7 Fault Locate Operation Event Table Field Description # Event Number: Indicates the event in sequence, where the higher the number the further distance from the OTDR the event occurs. “E” (End) which is the event determined to be the end of the fiber under test. The last column is labeled "L" the row included data that is relevant to the link (full fiber under test). Pass/Fail, if any one of the thresholds are not met for and event, the P/F column will display an F. The parameter that failed will be displayed in red. If all the parameters are met, this column will display a P. There is no Pass/Fail threshold for the last event labeled "E" (End) and the Pass/Fail for the "L" (Link) row includes the 2POINT column, which for the link is the total link loss and the TYPE column which for the link row is the system ORL. Km or KF or MI: Event Location (Distance from OTDR), labeled Km for Kilometer or KF if unit of measure is Kilo-feet MI for mile. This is the distance/location that the event occurs along the fiber link. This data should be the same for the End of Fiber and Link. Splice: SPLICE is the dB loss at the event at this location on the fiber. Loss is represented as a positive number. (A positive number is the amount of loss and a negative number indicates a gain normally due to mismatched index of refraction.) This is a settable threshold for the Pass/Fail purposes. The "E" event will display LINK as this is not an event that would have meaning. -

Chapter 8 OTDR Operation Warning Before connecting a fiber to the OTDR, be certain the fiber has no active optical sources or instruments con- nected to the other end. Skin or eye damage could result from high power sources such as EDFAs, and instru- ment damage could occur voiding the warranty. Warning Clean all connectors in use thoroughly prior to connection to the appropriate port of the OTDR. Failure to ensure the connectors used with the OTDR are properly cleaned can result in poor launch conditions at the minimum or damage to the optical interface that requires the unit be returned to the factory for repair. - Page 24 Chapter 8 OTDR Operation Warning Before connecting a fiber to the OTDR, be certain the fiber has no active optical sources or instruments con- nected to the other end.

Page 29: Loss Measurement Settings
Chapter 8 OTDR Operation Basic Splice Loss Splice Loss method is meant to be used in noisy environments 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. This is an estimation but this method may be more accurate than LSA Splice Loss method in noisy environments. When using the splice loss It is necessary to set the splice loss areas in clear backscatter (areas that do not consist of other events). - Page 30 Chapter 8 OTDR Operation Splice Loss Measurement Areas LSA Splice Loss Basic Splice Loss Measurement Areas Measurement Areas Active Splice Zone Cursor Active Splice Zone Cursor LSA Splice Loss Basic Splice Loss Measurements Measurements Fig 8.5 Splice Loss Adjustment Positions Splice Loss Position Splice Loss Position Splice Loss Position Splice Loss Position Fig 8.6 Note The vertical green line is used to show which point of the LSA measurement areas is the focus of the left and right buttons. To move to the next point, press the Select button.

Chapter 8 OTDR Operation 8.11 Event Analysis NOTE: When using the event table and the Fib-R-Map (schematic view), it is necessary to keep in mind that event analysis provides approximate l oss and distance measurements to quickly assist in network evaluation. Automatic detection results are not guaranteed and have their limits, possibly causing erroneous readings or detection failure. - Page 33 Chapter 8 OTDR Operation Sensitivity Settings There are three levels of sensitivity for the event table and Fib-R-Map. (See Fig 8.4) To set the event sensitivity, pull the menu down from the top of the display, move the Setting icon in the highlighted position and touch to open.

It is labeled E in the event number position and displays a vertical bar instead of horizontal.
- Page 35 Chapter 8 OTDR Operation Event Table Field Description # Event Number: Indicates the event in sequence, where the higher the number, the further distance from the OTDR the event occurs. “E” (End) is the event determined to be the End of Fiber (EOF). "L" (Link) is the information relative to the full fiber trace. Pass/Fail, if any one of the thresholds are not met for and event, the P/F column will display an "F". The parameter that failed will be displayed in red. If all the parameters are met, this column will display a "P". Km or KF or MI: Event Location per unit of measure, Km for Kilometer, KF for Kilo-feet and MI for mile. This is the distance/ location that the event occurs along the fiber link. Splice: Event Loss is the loss of the splice, mated pair, or other effect of the fiber considered an event. A positive number is the amount of dB loss and a negative number indicates a gain normally due to mismatched index of refraction. This is an adjustable threshold for the Pass/Fail feature. The "E" event will display N/A and the "L" Link displays Link, as these are not an event that would have meaning as a loss value. 2POINT: 2 Point Loss is the loss measured from the end of the dead zone of the previous event to the beginning of current event. The value in the "L" line of the table for this column is the link loss. The loss from the beginning of the trace to the event determined to be the EOF. This is the value used to determine if the fiber link passes or fails it's link threshold. dB/Km or Kf or Mi: dB per Kilometer if in KM and DB/KF if in Kilo-Feet and DB/MI if in mile unit of measure. This is the calculated loss per Km, Kf or Mi from the end of the dead zone of the previous event to the beginning of the current event. The value in the "L" line of the table for this column is the dB Per/KM, Kf or Mi for the total link.

Page 50: Visible Fault Locator
Chapter 13 Visible Fault Locator 13.1 VFL Safety Caution This Visual Fault Locator is classified as a Class II laser system and must be used with all commensu- rate safety precautions. Never view the light emanating from the fiber directly. Place a white piece of paper at the end of the fiber and look for the presence of a red spot on the paper. 13.2 VFL Description The Visual Fault Locator emits visible (red) light at the 650 nm wavelength. Its intended function is to allow an operator to identify the exact location of a break, micro bend, or other discontinuity in a fiber optic cable. As the radiation is visible, light emanating from a break or micro bend enables the user to locate the exact position of a fault even at very short distances that would not be detectable by conventional means such as an Optical Time- Domain Reflectometer, (OTDR). It is also useful for identifying a particular fiber in a cable by exciting the fiber to be located with visible radiation. -
