Fiber optic txuas kuj yog hom txuas cov khoom lag luam feem ntau siv hauv lub neej tiag tiag. Nws lub ntsiab tseem ceeb yog kom ua tiav qhov kev sib txuas ntawm cov khoom siv fiber ntau. Tam sim no nws tau dav siv nyob rau hauv fiber optic kev sib txuas lus kab ke rau fiber ntau kev sib txuas.Yog muaj ntau hom optical fiber txuas nrog cov qauv sib txawv, tab sis cov qauv yooj yim ntawm ntau hom optical fiber txuas txuas yog tib yam.Qhov feem ntau ntawm kev kho qhov muag fiber ntau qhov txuas yog qhov kev siv siab ntawm cov khoom sib txawv kom tau txais kev sib txuas ntawm kev sib txuas ntawm cov hluav taws xob fiber ntau, uas yog," los ntawm ob rab koob thiab txuas lub raj txuas tag nrho peb ntu ntawm cov khoom sib txuas" ;.
Thawj qhov kev ua haujlwm ntawm optical fiber txuas yog: kev ua haujlwm kho qhov muag, ntxiv rau qhov kev sib hloov ntawm cov khoom siv fiber ntau txuas ntxiv kom rov ua dua, lub zog tensile, kub thiab ntsaws thiab rub sijhawm, thiab lwm yam
1.Optical cov khoom
Rau kev ua tiav ntawm cov kho qhov muag fiber ntau, lub ntsiab qhov tseem ceeb yog qhov tsis nkag siab thiab rov qab poob ntawm ob qhov pib tshaj plaws.
a. Tso tsis tau, uas yog kev sib txuas poob, yog hais txog qhov poob ntawm qhov zoo ntawm lub zog ntawm qhov txuas los ntawm kev qhia ntawm tus txuas ntxiv.Qhov me me qhov tsis txaus, qhov zoo dua. Qhov yuav tsum tau dav dav yuav tsum tsis pub ntau tshaj 0.5dB.
b. Returnloss (ReflectionLoss) yog hais txog lub peev xwm ntawm cov txuas rau inhibit lub zog kho qhov muag ntawm qhov txuas, thiab nws tus nqi raug yuav tsum tsis pub tsawg tshaj 25dB.Qhov tseeb daim ntawv thov ntawm lub txuas, qhov saum npoo ntawm tus pin tau tshwj xeeb polished, tuaj yeem ua rau cov khoom xa rov qab yog ntau dua, feem ntau tsis tsawg tshaj 45dB.
2.Tensile lub zog
Rau cov khoom siv kho qhov muag ua tau zoo, qhov yuav tsum tau ua dhau ntawm lub zog tensile yuav tsum tsis pub tsawg dua 90N.
Peb, kev sib pauv hloov thiab rov ua dua
Fiber optic txuas yog khoom siv thoob ntiaj teb passive. Rau tib qho ntawm cov kab txuas hluav taws xob fiber ntau, lawv tuaj yeem siv cov kev hloov dav thiab ntau dua. Yog li no, qhov poob ploj ntxiv txawv teb chaws feem ntau yog nyob hauv qhov tsawg dua 0.2dB.
4.The tus lej ntsaws
Tam sim no siv cov kab hluav taws xob optical fiber feem ntau tuaj yeem txuas ntau dua 1000 zaug.
Tsib, qhov kub thiab txias
Feem ntau, cov khoom siv kho qhov muag kab hluav taws xob yuav tsum muaj peev xwm siv tau tas li ntawm qhov kub ntawm -40 ℃ ~ +70 ℃
