Kugirango tumenye neza ubuzima bwa serivisi bwumurongo wa optique ya fibre itumanaho, ibiranga ubushyuhe nibiranga imashini ya fibre optique nabyo ni ibintu bibiri byingenzi byerekana imikorere.
1. Ibiranga ubushyuhe bwa fibre optique
Gutakaza fibre optique birashobora gusobanurwa na coefficient ya attenuation ya fibre optique, kandi coefficente ya attenuation ya fibre optique ifitanye isano itaziguye n’imikorere ya sisitemu yo gutumanaho ya fibre optique, ni ukuvuga ko yiyongera ku ngaruka za ubushyuhe, cyane cyane mu karere k'ubushyuhe buke. Impamvu nyamukuru yo kongera coefficient ya attenuation ya fibre optique ni igihombo cya microbending no gutakaza igihombo cya fibre optique.
Gutakaza microbending ya fibre kubera ihindagurika ryubushyuhe biterwa no kwaguka kwinshi no kugabanuka. Birazwi muri fiziki ko coefficente yo kwagura ubushyuhe bwa dioxyde de silicon (SiO2) igizwe na fibre optique ari nto cyane, kandi ntigabanuka cyane iyo ubushyuhe bugabanutse. Fibre optique igomba gutwikirwa no kongerwaho nibindi bice mugihe cyo gukora umugozi. Kwiyongera kwingirakamaro yibikoresho byo gutwikira nibindi bikoresho ni binini. Iyo ubushyuhe bugabanutse, kugabanuka birakomeye. Kubwibyo, iyo ubushyuhe buhindutse, coefficente yo kwaguka yibikoresho iratandukanye. , Bizatera fibre optique yunamye gato, cyane cyane mukarere k'ubushyuhe buke.
Umurongo uri hagati yinyongera ya fibre nubushyuhe bwerekanwe mubishusho. Mugihe ubushyuhe bugabanutse, gutakaza fibre byiyongera buhoro buhoro. Iyo ubushyuhe bugabanutse kugera kuri -55 ° C, igihombo cyiyongera cyane.
Kubwibyo, mugihe dushushanya sisitemu yo gutumanaho ya fibre optique, birakenewe ko dusuzuma ibipimo byo hejuru nubushyuhe buke bwikizamini cya kabili ya optique kugirango tumenye niba gutakaza fibre optique byujuje ibisabwa nurutonde.
2. Ibikoresho biranga fibre optique
Kugirango harebwe niba fibre optique idacika mubikorwa bifatika kandi ifite igihe kirekire cyo kwizerwa iyo ikoreshejwe ahantu hatandukanye, birasabwa ko fibre optique igomba kuba ifite imbaraga zubukanishi.
Nkuko bizwi na bose, ibikoresho bigize fibre optique ya none ni SiO2, igomba gukururwa muri 125 mμm filaments. Mugihe cyo gushushanya, imbaraga zingana za fibre optique ni 10 ~ 20kg / mm². Imbaraga zirashobora kugera kuri 400kg / mm². Ibiranga ubukanishi dushaka kuganira ahanini bivuga imbaraga nubuzima bwa fibre.
Imbaraga za fibre optique hano yerekana imbaraga zingana. Iyo fibre ikorewe impagarara zirenze iyo ishobora kwihanganira, fibre izacika.
Kubijyanye no kumena imbaraga za fibre optique, bifitanye isano nubunini bwurwego. Iyo umubyimba wa coating ari 5 ~ 10μm, imbaraga zo kumena ni 330kg / mm², naho iyo umubyimba wa 100 mm, ushobora kugera kuri 530kg / mm².
Impamvu yo kumeneka kwa fibre iterwa nubusembwa bwubuso bwa preform ubwayo mugihe cyo gukora fibre optique. Iyo impagarara zakiriwe, imihangayiko iba yibanze ku nenge. Iyo impagarara zirenze urugero runaka, fibre iracika.
Kugirango tumenye neza ko fibre optique ishobora kugira ubuzima bwimyaka irenga 20, fibre optique igomba gukorerwa ikizamini cyo gusuzuma imbaraga. Gusa fibre optique yujuje ibisabwa irashobora gukoreshwa muri cabling.
Ibisabwa imbaraga za fibre mubihugu byamahanga bigaragara kumeza.
Optical fibre yemerewe imbaraga zirimo:
(1) imbaraga za fibre optique mugihe cabling;
(2) Ubwoko bwa fibre optique iterwa nibintu bimwe na bimwe mugihe ushyira umugozi wa optique;
(3) Ubwoko bwa fibre optique iterwa no guhindura ubushyuhe bwibidukikije bikora.
Dukurikije amakuru y’amahanga, iyo imbaraga za fibre optique ari 0.5%, ubuzima bwayo bushobora kugera ku myaka 20 kugeza 40.
