Chokutanga pane zvose, tambo yemaziso haityi mvura nokuti inodzivirirwa. Apo tambo ye optical inoshandurwa kuita tambo, kune zvinhu zviviri zvekudzivirira zvinodiwa kune fiber optical: imwe ndeyokuti optical fiber haina kunyanya kusimbiswa; imwe yacho ndeyekuti optical fiber inofanira kunge isina mvura. Iyo yekunze yakatsetseka yetambo ye optical sheath yepurasitiki, mukati isimbi sheath, uye mukati mune inovharira mvura inoputika nemvura, uye pakati petambo inonamirwa nemafuta uye optical fibers.
Tambo yemaziso ine magonhi mana asingapindi mvura, anoti: chivharo chepurasitiki, chivharo chesimbi, chivharo chemvura uye mafuta.
Saka mubvunzo ndewekuti, fiber core inotya mvura here? Harisi girazi chete, unotyei mvura?
Kutaura zvazviri, anotya mvura.
Iwe unogona kufunga kuti nei hove tangi girazi uye hwindo girazi kumba vasingatyi mvura asi kusapinda mvura, uye nei ese ari magirazi?
Sei fiber core ichitya mvura?
Zvinowanzotendwa kuti fiber core haityi mvura, nokuti girazi rine mvura yakanaka yekunamatira. Asi chokwadi, mvura inokuvadza zvakanyanya kutambo dzemaziso. Kana mvura ikapinda muoptical cable, inokuvadza optical fiber painotonhora uye ichiwedzera mumvura inotonhora, saka tambo yemaziso inofanira kuzadzwa nemafuta kudzivirira hunyoro kupinda.
Ongororo dzinoratidza kuti kupinda munyoro kwenguva refu mutambo yemaziso kuchawedzera kurasikirwa kwefiber optical, kunyanya pa1.55 pm wavelength.
Chikonzero nei optical fiber inotya mvura ndeyokuti optical fiber inoumbwa negirazi (SiO4) silicon-oxygen tetrahedra yakabatana pamwe chete, sezvinoratidzwa mumufananidzo 1. MuSi-O-Si network, maatomu eokisijeni aripo nenzira yeokisijeni. mabhiriji.
Zvisinei, munzvimbo yemvura, mushure mokunge magirazi adsorbs mhute yemvura, inononoka hydrolysis reaction inoitika, zvichiita kuti pave nekuputsika kwesilicon-oxygen bond mune yepakutanga-Si-O-hongu-, uye oksijeni yakavharwa inova isina kuvharwa okisijeni sezvakaratidzwa muMufananidzo 2, zvichiita kuti pave nekutsemuka mugirazi, uye kuputika kunoramba kuchikura.
Kunyangwe iri hove tank girazi, girazi rehwindo kana fiber optic girazi, munhu wese anotya mvura. Musiyano ndewekuti girazi retangi rehove uye girazi rehwindo zvakakora kwazvo, nekukora kwe3mm, 5mm uye 10mm. Kunyange kana pane 0.05mm kutsemuka, hazvizokanganisa simba regirazi Hapana shanduko kune ziso rakashama.
Girazi optical fiber yakasiyana-siyana yegirazi yefiber optical inongova 0.125mm, iyo yakakura sebvudzi kana pane kutsemuka kwe0.05mm, dhayamita yefiber optical ichava 0.075mm, saka fiber ndeye. zviri nyore kwazvo kutyora Mukuwedzera, kutaridzika kweOH midzi kuchawedzerawo kurasikirwa kwechiedza che optical fiber. Ichi ndicho chikonzero girazi rehove tangi uye girazi rehwindo hazvityi mvura, nepo fiber optic girazi inotya mvura.
Muchiitiko ichi, kana tambo ye optical yakakuvadzwa, kuiswa chisimbiso kwebhokisi rejunction hakuna kunaka uye fibre isina kuvharwa inoratidzwa, hupenyu hwebasa hwefiber optical huchapfupiswa uye fiber ichabva yaputsika nekuda kwemvura.
Nokudaro, kana iyo optical fiber yakavakwa mumatope, majoini anofanira kubatwa zvakanaka, uye kana optical fiber pachayo yakakuvadzwa, inofanira kugadziriswa. Usabvumira mukati me optical fiber kusangana nemvura.
