Page 13 Chapter Measurement Principles This chapter give the principle of measurement : ❏ for OTDR modules ❏ for OTS modules ❏ for the WDM modules OTDR measurements principle Optical time domain reflectometry consists of injecting a light pulse down the optical fiber to be analyzed and observing, at the point of injection, the intensity of the light reflected back in the opposite direction to the pulse propagation.
Page 14 Measurement Principles The measurement result should provide: • the attenuation • the location of faults in terms of distance from defined point • the attenuation versus distance (dB/km) • the reflectance of an event or an optical link In so far as location is concerned, it should be noted that an OTDR is Attention a time domain machine (Optical Time Domain Reflectometer).
Page 15 OTS Measurement principles • the backscattering coefficient of the fiber used. Typical values of backscattering coefficient for a 1ns pulse for a singlemode fiber - 79 dB at 1310 nm - 81 dB at 1550 nm and 1625 nm for a multimode fiber - 70 dB at 850 nm - 75 dB at 1300 nm In order to measure the largest range of reflection coefficient, a variable optical...
Page 16 Measurement Principles 2. The power P2 at the output of the fiber section of two meters is measured and serves as the reference. The attenuation of the fiber tested is: P1 - P2. This method is very accurate but is little used due to its destructive nature. It cannot be used during maintenance or installation but only during the manufacture of the fiber.
Page 17 WDM principle and analysis With this new technology, new measurements are required. During installation and maintenance of WDM systems, it is important to verify the following parameters: 1. Presence of all channels at corresponding wavelengths, without any drift. 2. Right channel power levels, without any power variation 3.

Page 71 Acquisition ❏ A manual acquisition mode that lets you configure your acquisition parameters exactly for the fiber you wish to test. After any acquisition (except in real time mode), an automatic measurement is performed. With multi-wavelength modules, the acquisition can be started automatically on all the wavelenghts, each time the button is pushed.
Page 72 Using an OTDR module Status Connection condition Indicates one of the following cases: There are several connectors close to the front end connector. One of the connectors is dirty or badly connected. You must re-connect or change the pigtail. There is no fiber connected. For a bad connection condition you can make measurements but very poor detection results should be expected.
Page 73 Acquisition Automatic acquisition mode The simplest way to quickly use the MTS to detect any faults on your fiber optic link is to make use of the automatic acquisition function that is provided. This function allows you to automatically configure the MTS to use the optimum acquisition parameters (pulsewidth and range) for the link under test with respect to the selected time.

If you do this, an automatic measurement is real- ized but certain events may not be detected because the instrument will not have made the required number of averages for an optimum measurement.
Page 76 Using an OTDR module Use the following procedure to configure your manual acquisition in the OTDR TEST SETUP window (refer to "Selecting measurement acquisition parameters" on page 5-3): 1. Select the Laser wavelength with the Acquisition:Laser option. 2. Select the Manual mode with the Acquisition:Mode option. 3.

Page 78 Using an OTDR module • Stop the measurement. • Disconnect the source sending out the signals in the fiber or disconnect the network fiber. • Restart the measurement. Result analysis Once you have completed an acquisition, Results are displayed to allow you to analyze the resulting trace.
Page 79 Zoom and shift functions Zoom and shift functions Zoom function The Zoom function allows you to analyze a detected event in greater detail. Using the Zoom function in combination with the Event function allows you to quickly verify any uncertain events. The zoom of the display is made around the selected cursor.
Page 80 Using an OTDR module Once you have made an acquisition and have results, you can simply press the Event key to move the cursor from event to event. Using this function in combination with the ZOOM and CURSOR keys allows you to rapidly analyze the fiber.
Page 81 Table of results 3. Use the Event key. The measurements given are the true distance from the < > beginning of the link, and the attenuation of the link plus the attenuation of the connection. This function may also be used to determine the loss budget for a partial section of the fiber under test.

Using this method of detection and measurement allows you to rapidly find all the events on the fiber under test.
Page 86 Using an OTDR module Adding markers To add event markers: 1. Select a cursor. 2. Use the positioning arrows to move the cursor to the position where you want to add a marker. 3. Press the <Marker> key. 4. An event marker is displayed at the cursor location and a full measurement is immediately performed.
