I-1.optical fiber core structure
I-1) Ingundoqo: isalathisi esiphezulu se-refractive, esisetyenziselwa ukuhambisa ukukhanya;
I-2) I-Cladding: isalathisi esisezantsi se-refractive, esenza imeko yokubonakalisa iyonke kunye nengundoqo;
3) Uluhlu olukhuselayo: lukhusela i-fiber optical.
2.Imowudi enye kunye neendlela ezininzi
Inye kuphela indlela yokukhanya enokuhanjiswa.Ke ngoko, i-inter-mode dispersion incinci kwaye ilungele unxibelelwano olukude, kodwa kukwakhona ukusasazwa kwezinto kunye nokusasazwa kwe-waveguide.Ngale ndlela, i-fiber yemodi enye ineemfuno eziphezulu zobubanzi be-spectral kunye nokuzinza komthombo wokukhanya, oko kukuthi, ububanzi be-spectral kufuneka bube buncinci kwaye uzinzo lungcono.Ifayibha yemowudi enye ine-zero epheleleyo.
Inokusasaza iindlela ezininzi zokukhanya.Nangona kunjalo, i-inter-mode yokusasazwa kwayo inkulu, ethintela ukuphindaphinda kokuhanjiswa kweempawu zedijithali, kwaye iya kuba mbi ngakumbi ngokunyuka komgama.Umgama wothumelo lwefayibha yeemowudi ezininzi mfutshane, ngokubanzi nje ziikhilomitha ezimbalwa.
Isixhobo semowudi enye sinokusebenza kwifiber yemowudi enye okanye ifayibha ezininzi, ngelixa izixhobo zemowudi ezininzi zinqunyelwe ekusebenzeni kwifiber yeemodi ezininzi.
