23 M200 OTDR Training www.AFLtele.com Specify a Range: 1.5 to 2 x length of fiber under test Live tests will be performed at ONLY one wavelength per test: –850 or 1300nm for Multimode –1310 or 1550nm for Single-mode Specify if using Launch &/or Receive cables, and their respective length Test Settings: Live Mode With the Mode line highlighted use the buttons to select Live

24 M200 OTDR Training www.AFLtele.com Expert Auto uses default settings to perform a test but allows the user to test at a single wavelength if desired Expert Auto tests can be performed at one or two wavelengths per test: –850 and/or 1300nm for Multimode –1310 and/or 1550nm for Single-mode Test Settings: Expert Mode Auto Highlight the Mode line and use the buttons to select Expert

25 M200 OTDR Training www.AFLtele.com In Expert Manual the user must know information about the fiber under test and how to set up an OTDR Expert Manual tests can be performed at one or two wavelengths per test: –850 and/or 1300nm for Multimode –1310 and/or 1550nm for Single-mode Test Settings: Expert Mode-Manual With the Mode line highlighted use the buttons to select Expert

26 M200 OTDR Training www.AFLtele.com Range: set to 1.5 to 2 x length of fiber under test including launch/receive cables Pulse: (see next slides) –Narrow pulses are best for resolving close events but are limited to short links. –Wide pulses are good for measuring long links Time (Averages): (see next slides) –Traces are always averaged over hundreds or thousands of pulses. –The trade-off is time vs. trace quality. –After about 3 min, you get very little additional improvement Filter: selectable as On or Off, –Smoothes choppy traces. –As a rule of thumb use with PW 1us or greater Test Settings: Expert Mode - Manual Use buttons to specify the parameters for testing

27 M200 OTDR Training www.AFLtele.com Range Too short: less than link length Link Can’t see entire link – unpredictable results Good: about 1.5x to 2x link length Link Good trace – can see end of fiber Too long: much larger than link length Link Trace is “squashed” into left side of display

28 M200 OTDR Training www.AFLtele.com Pulse Width Too wide: Can’t resolve events About right: Events can be seen and trace is smooth Too narrow: Trace “disappears” into noise floor Link Where is this this event?

29 M200 OTDR Training www.AFLtele.com Averages (Time) Too many Trace is smooth but waste of time About right: Trace is smooth Too few: Trace is noisy – noise floor is too high Link

50 M200 OTDR Training www.AFLtele.com TOOLS (cont.) If moving files it is recommended to copy and paste them not cut them Assure you have made a successful copy before cutting or deleting files/folders Example: 1310nm tests selected for copying Up/down & select were used to select the tests

51 M200 OTDR Training www.AFLtele.com Using an OTDR You must use a launch cable to measure the loss of the near-end connection You must use a receive cable to measure the loss of the far-end connection Both cables must use the same type fiber (50  m, 62.5  m, or single-mode) as the link under test For testing links under 2 km, the length of the launch and receive cables should be about 100 m, for long fibers under test, longer launch and receive cables may be needed

52 M200 OTDR Training www.AFLtele.com Without launch and receive cables the OTDR cannot measure the IL of the near-end or far-end connections. This is a problem in premises links, which are typically short, because these connections represent a large portion of total link loss. Fiber IL 12 Start eventEnd event Link No launch or receive cable

53 M200 OTDR Training www.AFLtele.com Adding the launch cable enables the OTDR to include the loss of the near-end connection in total link loss calculations, and measure its reflectance Adding a launch cable AB Fiber + Near- end IL Launch Cable Link

54 M200 OTDR Training www.AFLtele.com Adding a receive cable enables the OTDR to include the loss of the far-end connection in total link loss calculations, and measure its reflectance Adding the receive cable AB Link IL Launch Cable Link Receive Cable

55 M200 OTDR Training www.AFLtele.com If launch and receive cables are installed To see total link loss, view event table -- cumulative loss at last event will equal total or “end-to-end” link loss End-to-end link loss AB Link IL Launch Cable Link Receive Cable
