Chekutanga, fiber ye optical haityi mvura nekuti yakachengetedzwa. Kana fiber ye optical ikatenderedzwa kuita waya, pane zvinodiwa zviviri zvekudzivirira fiber ye optical: chekutanga ndechekuti fiber ye optical isanyanya kushushikana; chimwe ndechekuti fiber ye optical inofanira kunge isingapindi mvura. Chikamu chekunze chetambo ye optical fiber ipurasitiki, chikamu chemukati isimbi, uye chikamu chemukati ipurasitiki inovhara mvura inoputika kana yaiswa mumvura. Pakati petambo pakabatanidzwa ne sealant ne fiber ye optical.
Waya yemagetsi ine magonhi mana asingapindi mvura, anoti: chifukidziro chepurasitiki, chifukidziro chesimbi, chifukidziro chemvura, uye mafuta ekuzora.
Saka mubvunzo ndewokuti, fiber core inotya mvura here? Harisi girazi chete here, chii chinonyanya kukosha nezvemvura?
Kutaura zvazviri, anotya mvura.
Ungashamisika kuti sei magirazi ari mumatangi ehove nemahwindo mumba mako asingatyi mvura asi asingapindi mvura, uye kuti sei ese akagadzirwa negirazi.
Sei musimboti wefiber uchitya mvura?
Zvinowanzo fungidzirwa kuti mukati mefiber hamukanganisike nemvura nekuti girazi harina simba rekudzivirira mvura. Zvisinei, mvura inokuvadza zvakanyanya tambo dzeoptical. Kana mvura ikapinda mutambo dzeoptical, inokuvadza tambo yacho painooma uye ichikura mumvura inotonhora. Saka, tambo dzeoptical dzinofanira kuputirwa nechivharo kudzivirira hunyoro kuti husapinde.
Ongororo dzinoratidza kuti kupinda kwenguva refu kwehunyoro mutambo ye optical kunowedzera kurasikirwa kwe optical fiber, kunyanya pahurefu hwe 1.55 pm.
Chikonzero chinoita kuti fiber ye optical itye mvura ndechekuti fiber ye optical inoumbwa nesilicon-oxygen (SiO4) girazi tetrahedra yakabatana pamwe chete, sezvakaratidzwa muMufananidzo 1. Mune network yeSi-O-Si, maatomu eokisijeni aripo muchimiro chemabhiriji eokisijeni.
Zvisinei, munzvimbo ine mvura, mushure mekunge girazi ranyudza utsi hwemvura, hydrolysis inononoka kuitika, zvichikonzera kutyoka kwesilicon-oxygen bond mu network yekutanga —Si—O—Si—, uye bhiriji reokisijeni rinova okisijeni isina kuvharwa sezvakaratidzwa muMufananidzo 2, zvichikonzera kutsemuka mugirazi, uye kutsemuka kunoramba kuchikura.
Ingava girazi retangi rehove, girazi repahwindo, kana girazi refiber optic, zvese izvi zvinogona kukuvara nemvura. Musiyano ndewekuti girazi retangi rehove negirazi repahwindo zvakakora zvikuru, zvine ukobvu hwe3 mm, 5 mm, uye 10 mm. Kunyangwe kutsemuka kwe0.05 mm hakuzokanganisi simba regirazi. Hapana shanduko dzinooneka.
Fiber yemaziso yakasiyana. Dhayamita yegirazi iri mufiber yemaziso inongova 0.125 mm, iyo yakakora sebvudzi remunhu. Kana paine 0.05 mm yakatsemuka, dhayamita yefiber yemaziso ichave 0.075 mm, zvichiita kuti fiber ive nyore kutyoka. Uyezve, kutaridzika kwemidzi yeOH kuchawedzerawo kugona kwefiber yemaziso kupinza chiedza. Ndokusaka girazi retangi rehove negirazi rewindo hazvikanganisike nemvura, nepo girazi refiber yemaziso richikuvadzwa nemvura.
Muchiitiko ichi, kana tambo ye optical yakakuvara, splice box seal haina kunaka uye bare fiber ikafumurwa, hupenyu hwe optical fiber huchapfupikiswa uye fiber ichatsemuka yega nekuda kwemvura.
Saka, kana tambo ye fiber optic yakaiswa mupombi dzemvura, zvidimbu zvinofanirwa kusungwa zvakanaka, uye kana tambo ye fiber optic pachayo yakakuvara, inofanira kugadziriswa. Usabvumira mukati metambo ye fiber optic kuti mubate mvura.
