Page 37: Principles Of Measurement
Principles of measurement Chapter 1 This chapter gives the principles of the measurements made by the reflectometer (OTDR) plug-ins, OSA spectrum analyzers (WDM technology) and PMD analyzers (Polarization mode dispersion). The topics discussed in this chapter are as follows: • “Principle of reflectometry measurements”...
Page 38: Principle Of Reflectometry Measurements
Chapter 1 Principles of measurement Principle of reflectometry measurements Principle of reflectometry measurements Optical time domain reflectometry consists in injecting a light pulse into one end of the optical fiber to be analyzed and observing, at the same end, the optical intensity passing through the fiber in the opposite direction to the propagation of the pulse.
Page 39: Validity Of Measurement
Chapter 1 Principles of measurement Principle of reflectometry measurements To locate faults, a reflectometer measures only time. Consequently, group velocity must be introduced in order to determine the distance of the loca- tion. This is done by introducing the refractive index of the fiber into the instrument.
Page 40: Principle Of Bi-Directional Measurement
Chapter 1 Principles of measurement Principle of bi-directional measurement • typical values of the backscatter coefficient for a pulse of 1 ns and – for a single-mode fiber: -79 dB to 1310 nm -81 dB to 1550 nm and 1625 nm –...

Chapter 1 Principles of measurement Principle of the optical power and attenuation measurements Figure 3 Positive splice (A ->B) / Negative Splice (B -> A) The sum gives the bi-directional or average splice loss value: ------------------ - Bi-directionnal measurement consists in performing a measurement from the extremity of fiber A, then another measurement from the extremity of fiber B, finally get events of both traces and calculate the average for all slope, splice and reflectance measure- ments.

Page 43: Pmd Principle
Chapter 1 Principles of measurement PMD principle PMD principle The transmission rate and range are two of the most important parameters of fiber optics paths and must therefore be optimized. And, since more and more paths (including those already installed) are being used for transmitting Wavelength Division Multiplex (WDM) signals or for bit rates of 10 Gbit/s, it is becoming all the more important to deter- mine the Polarization Mode Dispersion (PMD).
Page 44 Chapter 1 Principles of measurement PMD principle Figure 5 Fixed Analyzer Method used to measure the PMD Broadband Fixed Rotatable Optical Spectrum light source Polarizer Analyzer (OSA) Polarizer Link under test (SLED) The method used to measure PMD is the Fast Fourier Transform Method (FFT). From the spectrum, the mean period of the amplitude modulation is measured.

Chapter 1 Principles of measurement Principle of measurement of Chromatic Dispersion (CD ODM) using phase shift method Principle of measurement of Chromatic Dispersion (CD ODM) using phase shift method The Phase shift method A modulated broadband light is sent over the Fiber Under Test.

Chapter 3 Reflectometry measurements Advanced functions in Expert OTDR mode Measurement of Reflectance It is possible to carry out a reflectance measurement of a Fresnel for a reflective event. Follow the following procedure to measure the reflectance: Position the cursor A at the base of the peak Position the cursor B at the top of the peak of the required Fresnel, or after the peak to calculate automatically the maximum reflectance.
Page 130 Chapter 3 Reflectometry measurements Advanced functions in Expert OTDR mode If very close events have created a dead zone preventing the measurement of slope by the five-cursor method, it is possible to use the two-cursor method. This considers the difference in level between the cursors. Before performing one of these measurements, define in the Setup menu the splice detection threshold.

Page 311: Limitations
Chapter 8 Optical Spectrum Measurement Channel filtering Noise power is measured at the center frequency of the switched-off channels. Noise power is normalized to Noise Acq BW (i.g. 0.1nm) according to the setup param- eter. OSNR will be calculated and displayed in the table based on stored P_ch (step 1). Limitations The On/Off-OSNR method requires an intervention into the optical system as the optical channel to be measured needs to be switched-off.
