5 Introduction to the OTDR 5.1 The measuring Purpose of the OTDR An OTDR displays the power of the returned signal related to distance. The information can be used to confirm the transmission quality of a fiber optic link. 5.1.1 Measuring Contents of the OTDR Position (distance) of event, result or fractured position of fiber optic link;... - Page 12 Distance calculation formula of the OTDR: Distance = (c/n) × (t/2) Among which: c= speed of light in vacuum (2.998 x 108 m/s) t = Time delay between transmitted pulse and received pulse n = refractivity of optical fiber during testing process (nominated by manufacturer) When displaying the whole trace, each point on the trace graph represents the average value of several sampling points.
- Page 13 5.3.1 Initial Event “Initial event” on the OTDR trace is the event that marks the starting point of optical fiber. Under default conditions, “initial event” is located at the first event (usually it will be the first connector of the OTDR) of the tested optical fiber.
- Page 14 5.3.4 Non-reflection Event Non-reflection event brings loss on the whole transmission link of optical fiber, but no light reflection. On the curve, non-reflection event is shown as drop of optical power, as shown in Fig.6-3. Fig.6-3 Non-reflection Event 5.3.5 Event Inspection An OTDR sends an optical pulse into the optical fiber under inspection, then, begins to accept the returned optical signal immediately, and calculates the distance of an “event”...

(2) No.: Number of current event. (3) Distance (km): Distance between current event point and reference origin point. (4) Attenuation (dB/km): Average loss of the optical fiber section ahead of current event point. (5) Loss (dB): Connection loss measured at current event point. * It indicates the connection loss measured currently is bigger than the set critical threshold of the connection loss. -

Functions of all buttons on the menu bar are shown below: 【Avg.】: It is used to control the OTDR progressive average of the average times set against the lost curve tested; after test, the contents shown on the button changes automatically from 【Stop】 to 【Avg.】, and the OTDR test stops at the same time. - Page 20 Fig. 3-5 Window of setting Y3 SERIES70 OTDR test conditions 5.1Testing optical fiber link The operation steps are shown as follows: Select the test wave length. Set such test conditions as the test mode. Clean the optical fiber to be tested. Connect the optical fiber to be tested to corresponding OTDR fiber output port.
- Page 21 If the OTDR test mode is set to manual: Click 【Real Time】 in the main menu bar (and 【Real Time】 is changed to 【Stop】 at this time) to conduct sweep test on the optical fiber link under test in real time as per the test conditions set at present, and refresh the test curve in the main operation window continuously.

Otherwise, when one of the cursors is moved, the other one will not move. High resolution test: Select it to rise the sampling points of the instrument to 256k, improving the resolution capability on short-distance events occurred on the optical fiber link under test.

- Page 24 Test the curve again with big attenuation with current pulse width set (select the average test mode and set certain average times in this case). Event points are too close with each other in the test curve. In case of any adjacent event points being omitted, try to solve the problem as follows: Test the curve again with small pulse width (select the average test mode and set certain average times in this case).
