If your “18” refers to Chapter 18, the centerpiece is chromatic dispersion. Dukić explains that different wavelengths travel at slightly different speeds in silica glass. This causes pulse broadening, which limits the bit rate–distance product.
Key formula from Dukić’s Chapter 18:
[ \Delta T_\textchrom = D \cdot L \cdot \Delta \lambda ]
Where:
For standard single-mode fiber at 1550 nm, ( D \approx 17 ) ps/(nm·km). If your laser has ( \Delta \lambda = 0.1 ) nm and length ( L = 100 ) km, the spread is 170 ps. For a 10 Gb/s system (bit period = 100 ps), this spread would cause intersymbol interference unless compensated.
Dukić then introduces dispersion-shifted fibers and dispersion compensation modules (DCMs). These practical sections explain why telecom engineers use specific fiber types for different network segments (metro vs. long-haul). principi telekomunikacija miroslav dukic pdf 18
The book covers the physical and link layers of communication systems. It is typically used in the third or fourth year of an electrical engineering bachelor’s degree. The main topics include:
The book ends with a chapter on modern networks (often LTE/5G fundamentals in later editions). For standard single-mode fiber at 1550 nm, (
Instead of searching for “pdf 18,” consider these legal and often free options:
| Source | What it provides | |--------|------------------| | University library (physical or digital) | Borrow the latest edition. Many university libraries offer digital lending for a few hours or days. | | Google Books / limited preview | Sometimes older editions have partial previews – enough to see page 18 or chapter 18 contents. | | Author’s or publisher’s website | Check if Akademska misao (the publisher) has released sample chapters. | | Course Moodle / Canvas | Your professor may legally upload excerpts (fair use for education). | | Second-hand bookstores | KupujemProdajem, Limundo, or local Facebook groups – buy a used copy cheaply. | | Library Genesis (LibGen) caution | Although many students use it, it is illegal and exposes you to malware. Not recommended. | The book ends with a chapter on modern
