Chiedza chatinonyanya kujaira ndicho chokwadi chiedza chatinogona kuona neziso.Meso edu anonyatsonzwa kune chiedza chepepuru chine wavelength ye400nm kune chiedza chitsvuku pa700nm.Asi kune optical fibers inotakura girazi fibers, tinoshandisa chiedza munzvimbo ye infrared.Magetsi aya ane mawavelength akareba, kusakuvadzwa kudiki kune optical fibers, uye haaonekwe nemeso.Ichi chinyorwa chinokupa tsananguro yakadzama yewavelength yefiber optical uye nei uchifanira kusarudza aya wavelengths.
Tsanangudzo yewavelength
Kutaura zvazviri, chiedza chinotsanangurwa nehurefu hwacho.Wavelength inhamba inomiririra ruvara rwechiedza.Kuwanda, kana kuti ruvara, kwechiedza chimwe nechimwe chine wavelength inobatanidzwa nacho.Wavelength uye frequency zvakabatana.Kazhinji kutaura, mapfupi-wave radiation anozivikanwa nehurefu hwayo, nepo-refu-wave radiation ichizivikanwa nekuwanda kwayo.
Yakajairika wavelengths mune optical fibers
Iyo yakajairika wavelength inowanzo 800 kusvika 1600nm, asi parizvino, anonyanya kushandiswa wavelengths mune optical fibers 850nm, 1300nm uye 1550nm.Multimode fiber inokodzera wavelengths ye850nm uye 1300nm, nepo single mode fiber inonyanya kushandiswa kune wavelengths ye1310nm uye 1550nm.Musiyano uripo pakati pewavelength ye1300nm uye 1310nm ingori muzita rechinyakare.Laser uye light-emitting diode anoshandiswawo pakuparadzira mwenje mune optical fibers.MaLaser akareba kupfuura ma-single-mode madivayiri ane wavelengths e1310nm kana 1550nm, ukuwo malight-emitting diode achishandiswa kumidziyo yemultimode ine wavelengths ye850nm kana 1300nm.
Sei uchisarudza aya wavelengths?
Sezvambotaurwa, anonyanya kushandiswa wavelengths mune optical fibers ndeye 850nm, 1300nm uye 1550nm.Asi sei tichisarudza aya mafungu matatu echiedza?Imhaka yokuti zviratidzo zvemaziso zveaya matatu mawavelengths ane kurasikirwa kuduku paanoendeswa mufiber optical.Saka ivo vanonyanya kukodzera sezviwanikwa zvechiedza zvekufambisa mune optical fibers.Kurasikirwa kwegirazi fiber kunonyanya kunobva kuzvinhu zviviri: kunyura kurasikirwa uye. kuparadzira kurasikirwa.Kurashikirwa kwekunyura kunonyanya kuitika pamawavelengths mashoma atinodaidza kuti "mabhandi emvura", kunyanya nekuda kwekutorwa kwemadonhwe emvura mugirazi.Kupararira kunonyanya kukonzerwa nekudzokororwa kwemaatomu nemamorekuru pagirazi.Kupararira kwemafungu akareba kudiki zvakanyanya, iri ndiro basa guru rewavelength.
Mukupedzisa
Mushure mekuverenga chinyorwa ichi, iwe unogona kuve nekumwe kunzwisisa kwekutanga kwemawavelengths anoshandiswa mune optical fibers.Nekuti iyo wavelength kurasikirwa kwe850nm, 1300nm uye 1550nm yakadzikira, ivo isarudzo yakanakisa ye optical fiber kutaurirana.
