Kuziva kutaurirana kwe optical fiber kwakavakirwa panheyo yekuratidza chiedza chose.
Kana chiedza chikapararira pakati pe fiber ye optical, refractive index n1 ye fiber core yakakwira kupfuura ye cladding n2, uye kurasikirwa kwe core kwakaderera pane kwe cladding, zvekuti chiedza chicharatidzwa zvizere, uye simba rayo rechiedza rinonyanya kutumirwa mukati me core. Nekuda kwe spectrums dzakatevedzana, chiedza chinogona kutumirwa kubva kune rimwe divi kuenda kune rimwe.
Yakarongwa nenzira yekutumira: nzira imwe chete uye nzira dzakawanda.
Modhi imwe chete ine dhayamita diki yepakati uye inogona kungotumira mafungu echiedza chemodhi imwe chete.
Multi-mode optical fiber ine dhayamita yakakura uye inogona kutumira mafungu echiedza mumhando dzakasiyana-siyana.
Tinogonawo kusiyanisa single-mode optical fiber kubva kune multi-mode optical fiber neruvara rwechitarisiko.
Mazhinji mafiber emagetsi emhando imwe chete ane jekete yeyero nebhuruu, uye tambo yepakati i9.0 μm. Kune mawavelength maviri epakati efiber yemhando imwe chete: 1310 nm uye 1550 nm. 1310 nm inowanzo shandiswa pakutumira mapfupi, madaro ari pakati kana madaro marefu, uye 1550 nm inoshandiswa pakutumira madaro marefu uye madaro marefu. Daro rekutumira rinoenderana nesimba rekutumira remodule ye optical. Daro rekutumira remodule ye1310 nm single-mode i10 km, 30 km, 40 km, nezvimwewo, uye daro rekutumira remode ye1550 nm single-mode i40 km, 70 km, 100 km, nezvimwewo.
Mafiber emagetsi emhando dzakasiyana-siyana anowanzova jekete reorenji/grey rine zvibatanidza zvitema/beige, 50.0 μm uye 62.5 μm cores. Hurefu hwepakati hwefiber yemhando dzakasiyana-siyana hunowanzova 850 nm. Daro rekutumirwa kwefiber yemhando dzakasiyana-siyana ipfupi, kazhinji mukati me500 m.
