Pri dopade svetelného lúča na rozhranie jadra a obalu pod dostatočne veľkým uhlom dopadu (dostatočne „plocho“ či „tupo“), nastáva <a href="/w/index.php?title=%C3%9Apln%C3%BD_odraz&action=edit&redlink=1" class="new" title="Úplný odraz (stránka neexistuje)">úplný odraz</a>. Sériou takýchto odrazov sa lúč šíri z jedného konca vlákna na druhé. </p><p>Z tohoto princípu vyplývajú niektoré technologické obmedzenia pri použití optických vlákien. Predovšetkým ide o ohyb: keďže v ohnutom vlákne dopadá lúč na rozhranie jadro/obal pod iným uhlom ako v rovnom vlákne je možné, že nastane len čiastočný odraz a časť svetla unikne (čo sa pre prenesené svetlo prejaví ako zvýšený útlm). Preto je dôležité dodržať minimálny predpísaný polomer ohybu pre dané vlákno (toto pochopiteľne závisí od pomeru indexov lomu jadra a obalu, takže neexistuje univerzálna hodnota pre všetky vlákna). </p><p>Ďalším javom je uhol, v ktorom je potrebné umiestniť zdroj svetla, aby jeho svetlo bolo nadviazané do vlákna tak, aby sa ďalej šírilo vláknom (tzv. <a href="/w/index.php?title=Numerick%C3%A1_apert%C3%BAra&action=edit&redlink=1" class="new" title="Numerická apertúra (stránka neexistuje)">numerická apertúra</a>, <a href="/w/index.php?title=%C3%9Ahlov%C3%A1_apert%C3%BAra&action=edit&redlink=1" class="new" title="Úhlová apertúra (stránka neexistuje)">úhlová apertúra</a>). Tento tiež závisí od rozdielov indexov lomu jadra a obalu a tiež od priemeru jadra a býva pomerne malý, z čoho vyplýva náročnosť polohovania zdroja svetla a detektora voči koncom vlákna. </p> <div class="mw-heading mw-heading2"><h2 id="Druhy_optických_vlákien"><span id="Druhy_optick.C3.BDch_vl.C3.A1kien"></span>Druhy optických vlákien</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Optick%C3%A9_vl%C3%A1kno&veaction=edit&section=2" title="Upraviť sekciu: Druhy optických vlákien" class="mw-editsection-visualeditor"><span>upraviť</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Optick%C3%A9_vl%C3%A1kno&action=edit&section=2" title="Editovat zdrojový kód sekce Druhy optických vlákien"><span>upraviť zdroj</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="Materiály"><span id="Materi.C3.A1ly"></span>Materiály</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Optick%C3%A9_vl%C3%A1kno&veaction=edit&section=3" title="Upraviť sekciu: Materiály" class="mw-editsection-visualeditor"><span>upraviť</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Optick%C3%A9_vl%C3%A1kno&action=edit&section=3" title="Editovat zdrojový kód sekce Materiály"><span>upraviť zdroj</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Pre diaľkové optické <a href="/wiki/Telekomunik%C3%A1cie" title="Telekomunikácie">komunikácie</a> sa používa <a href="/wiki/Kreme%C5%88" title="Kremeň">kremičité</a> <a href="/wiki/Sklo" title="Sklo">sklo</a> (SiO<sub>2</sub>).

Preto sa pre diaľkové spoje používa tzv. jednovidové (monomódové, singlemódové) vlákno s menším priemerom jadra a jedným nosným svetelným lúčom.
