Imicu ye-Optical iyingxenye ebalulekile yokuxhumana yesimanje kanye nezinhlelo zokudlulisa idatha. Zisetshenziselwa ukudlulisa amasiginali okubona ebangeni elide ngokulahleka okuncane kwamandla esignali. Kunezinhlobo eziningi ze-fiber optics, ngayinye enezici zayo ezihlukile kanye nokusebenza kwayo.
1. I-fiber optical yemodi eyodwa: I-diameter eyinhloko ye-fiber optical yemodi eyodwa incane, ngokuvamile izungeze ama-microns angu-9. Zenzelwe ukuthwala imodi eyodwa yokukhanya, okuvumela umkhawulokudonsa ophezulu kanye nokudluliswa kwebanga elide. I-fiber yemodi eyodwa ivamise ukusetshenziswa ezokuxhumana ezikude kanye namanethiwekhi edatha anesivinini esikhulu.
2. I-Multimode optical fiber: Ububanzi obuyingqikithi ye-multimode optical fiber bukhulu, ngokuvamile buzungeze ama-microns angu-50 noma angu-62.5. Angakwazi ukuthwala izindlela eziningi zokukhanya, okuvumela umkhawulokudonsa ophansi kanye namabanga amafushane okudlulisela kunefiber yemodi eyodwa. I-Multimode fiber ivamise ukusetshenziswa ezinhlelweni zebanga elifushane njengamanethiwekhi endawo (ama-LAN) nezikhungo zedatha.
3. I-Plastic optical fiber (POF): I-POF yenziwe ngezinto zepulasitiki ezifana ne-polymethylmethacrylate (PMMA). Inobubanzi obuwumgogodla omkhulu futhi ivumelana nezimo kune-fiberglass, okwenza kube lula ukuyifaka nokubamba. I-POF ivame ukusetshenziswa kuma-electronics abathengi, izinhlelo zokusebenza zezimoto kanye namanethiwekhi asekhaya.
4. I-Gradient index fiber: Inkomba ye-refractive ye-core index fibre core iyancipha kancane kancane ukusuka phakathi nendawo kuya onqenqemeni olungaphandle. Lo mklamo usiza ukunciphisa ukuhlakazeka kwe-modal uma kuqhathaniswa nefayibha ye-multimode evamile, okuvumela umkhawulokudonsa ophezulu kanye namabanga amade okudlulisela.
5. I-Polarization Igcina I-Fiber: Lolu hlobo lwefayibha luklanyelwe ukugcina i-polarization yokukhanya njengoba ihamba phakathi kwefayibha. Ivamise ukusetshenziswa ezinhlelweni lapho ukugcinwa kwesimo sokukhanya kubalulekile, njengezinzwa ze-fiber optic kanye nezinhlelo ze-interferometric.
Uhlobo ngalunye lwefayibha lunezinzuzo nemikhawulo yalo, futhi ukukhetha uhlobo olufanele kuncike ezidingweni ezithile zohlelo lokusebenza. Njengoba ubuchwepheshe buqhubeka buthuthuka, izinhlobo ezintsha zemicu ye-optical ziyathuthukiswa ukuze zihlangabezane nesidingo esikhulayo samanethiwekhi okuxhumana anesivinini esikhulu, anamandla amakhulu. Ukuqonda izici zezinhlobo ezahlukene zemicu ye-optical kubalulekile ekuklameni nasekusebenziseni izinhlelo zokuxhumana ezisebenza kahle nezithembekile.
