Page 35: Principles Of Measurement
Principles of measurement Chapter 1 This chapter gives the principles of the measurements made by the reflec- tometer (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 36: 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 37: Validity Of Measurement
Chapter 1 Principles of measurement Principle of reflectometry measurements • the attenuation • the location of faults, by their distance from a point of origin, • attenuation with respect to distance (dB/km) • the reflectance of a reflective event or a link. To locate faults, a reflectometer measures only time.
Page 38 Chapter 1 Principles of measurement Principle of reflectometry measurements controlled, they may degrade the performance of the system by perturbing the operation of the emitting laser (especially DFB lasers) or may generate interference noise in the receiver by multiple reflections. The reflectometer is particularly well suited to the measurement of discrete reflectances on an optical fiber link.
Page 39: Principle Of Bi-Directional Measurement
Chapter 1 Principles of measurement Principle of bi-directional measurement Principle of bi-directional measurement If fibers with different mode-field diameters (core size etc.) are joined, the resulting OTDR trace waveform can show a higher backscattering level. This is due to the increased level of backscattered signal reflected back to the OTDR in the downstream fiber.

Page 42: 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 transmit- ting Wavelength Division Multiplex (WDM) signals or for bit rates of 10 Gbit/ s, it is becoming all the more important to determine the Polarization Mode Dispersion (PMD).
Page 43: Method Used To Measure The Pmd
Chapter 1 Principles of measurement PMD principle Method used to measure the PMD The method used to measure the PMD is based on the Fixed Analyzer Method which requires a broadband polarized source at one extremity, and a polarized (variable) Optical Spectrum Analyzer (OSA) at the other extremity.

Chapter 8 Optical Spectrum Measurement Channel filtering 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. This is only applicable for an out-of-service measurement. Some ROADM networks contain so called 'self-blocking' ROADMs. These kind of ROADMs will block all light including the noise, when there is no signal present (switched-off).
