5 Definition l 1 l 2 l N l 1 l 2 l 1 l 2 l N OA l N OMU ODU Dense wavelength division multiplexing (DWDM) is a fiber optic transmission technique that employs light wavelengths to transmit data parallel-by-bit or serial-by-character.
6 Characteristics power dbm) wavelength interval : 1 ~ 10 nm nm wavelength
7 System Working Wavelength No Central Frequency (THz) Wavelength (nm)

16 Transmission Characteristics
17 Types of Optic Fibers G.652 : A single-mode optical fiber that has a nominal zero-dispersion wavelength in the 1310 nm window. (dispersion-unshifted fiber) G.653 : Dispersion-shifted fiber, zero dispersion at 1550 nm window, easy to cause FWM. G.655 : Non-zero dispersion fiber; used in 1550 nm window. Less dispersion coefficient, dispersion limited transmission distance can be hundreds of km; prevent FWM
18 Attenuation (db/km) Attenuation NZDF+ G.655+ NZDF- G.655- G.652 SMF EDFA Bandwidth G.653 DSF Dispersion (ps/nm-km) Wavelength (nm)
19 WDM Wavelength According to the characteristic of fibers and EDFA, the wavelength between 1525 nm and 1565 nm is used
20 Transport characteristics of optical fibers Attenuation Dispersion Non-linear Effect
21 Attenuation It is the reduction of signal strength or light power over the length of the light-carrying medium. Fiber attenuation is measured in decibels per kilometer (db/km).
22 Attenuation Absorbency Attenuation Intrinsic Absorbency Attenuation Impurity Absorbency Attenuation Scattering Attenuation
23 Dispersion T Optical signals of different wavelengths have different speeds in the optical fiber, and this will cause a phenomena called dispersion.
24 Influence of Dispersion Input Output Time Time
25 Kinds of Dispersion 1. Chromatic Dispersion 2. Polarization Mode Dispersion
26 Chromatic Dispersion It represents the fact that different colors or wavelengths travel at different speeds, even within the same mode. Chromatic dispersion is the result of material dispersion, waveguide dispersion, or profile dispersion.
27 Chirp The directly modulated signal will cause more chirp and more dispersion. T
28 Dispersion Tolerance Parameter of dispersion tolerance for laser source (Ds) Dispersion parameter for optical fiber (D) Longest transmission distance: Ds/D Example If Ds = ps/nm, SMF G.652 dispersion is D = 20 ps/km/nm and then the longest transmission distance of this optical source is 640km.
29 Polarization Mode Dispersion This problem occurs because the fiber is not consistent along its length. Due to bending and twisting, as well as temperature changes, the fiber core is not exactly circular. The result is that the modes in the fiber exchange power with each other in a random fashion down the fiber length, which result in different group velocities; the signal breaks up. In effect, the light travels faster on one polarization plane than another.
30 Nonlinear Effects 1. Brillouin Scattering 2. Stimulated Raman Scattering 3. Four Wave Mixing 4. Self-phase Modulation 5. Cross-phase Modulation 6. Intermodulation (Mixing)
31 Causes of Nonlinearities 1. Refractive index of the glass 2. Scattering phenomena

More informationThere are lots of problems or challenges with fiber, Attenuation, Reflections, Dispersion and so on. So here we will look at these problems.
The Hard theory The Hard Theory An introduction to fiber, should also include a section with some of the difficult theory. So if everything else in the book was very easily understood, then this section
