Optic fiber transceiverndi chida chotsika mtengo komanso chosinthika.Zomwe zimagwiritsidwa ntchito nthawi zambiri ndikusintha ma sign amagetsi mumagulu opotoka kukhala ma siginecha owoneka.Nthawi zambiri amagwiritsidwa ntchito mu zingwe zamkuwa za Efaneti zomwe sizingaphimbidwe ndipo zimayenera kugwiritsa ntchito ulusi wa kuwala kukulitsa mtunda wotumizira.M'malo enieni a netiweki, imathandizanso kwambiri kulumikiza mizere yomaliza ya fiber optic mizere ku netiweki ya Metropolitan ndi netiweki yakunja.Switch ndi chipangizo cha netiweki chomwe chimagwiritsidwa ntchito potumiza ma siginecha zamagetsi (zowoneka), ndipo chimagwira gawo lalikulu pakulumikizana pakati pa zida zamawaya (monga makompyuta, osindikiza, makompyuta, ndi zina zambiri).
