Koj puas paub qhov kev paub yooj yim ntawm cov tshuaj fiber ntau?

Raws li kev sib kis hom ntawm lub teeb nyob rau hauv cov fiber: ib-hom fiber thiab ntau hom fiber ntau

Lub tub ntxhais txoj kab uas muaj feem ntawm lub plawv ntawm cov cladding yog 125 μm, wavy wavelength 1.31 μm thiab 1.55 μm. Cov fiber ntau tsawg dua tsawg dua nrog nthwv dej. Qhov poob ntawm 0.85 μm yog 2.5db / km, poob ntawm 1.31 μm yog 0.35db / km, thiab poob qis tshaj plaws poob ntawm optical fiber.

Ntau Ntau

Multalode Fibera: The central iav tseem yog thicker (50 lossis 62.5 μm), uas nws yuav ua rau cov cim digital, thiab nws yuav dhau los ua kom deb li deb. Piv txwv li, 600MB / KM fiber muaj tsuas yog 300MB bandwidth ntawm 2km, yog li kev kis nrug ntawm multimode fiber ntau kuj tsuas yog ob peb mais xwb.

Ib-hom Fiber:

Ib-hom fiber ntau-hom fiber ntau: lub central iav tub ntxhais yog heev nyias (cov tub ntxhais lub taub feem ntau 9 txog rau ib hom teeb tau kis tau. Yog li ntawd, nws intermodal dispersion yog qhov me me, tab sis kuj tseem muaj cov khoom tawg, yog li ib qho kev sib cais, yog li ib qho kev cuam tshuam nrog kev sib cais, yog li ib qho kev cuam tshuam wave muaj cov teeb meem loj thiab ruaj khov ntawm lub teeb ci. Ua tau zoo. Tom qab ntawd tau pom tias nyob rau ntawm lub wavelength ntawm 1.31 μm, cov khoom tawg thiab cov waveGuide dispersion ntawm ib-hom fiber ntau yog qhov zoo thiab tsis zoo, thiab cov magnitudes zoo ib yam. Qhov no txhais tau tias ntawm nthwv dej 1.31 μm, tag nrho cov dispersion ntawm ib hom fiber ntau-hom fiber ntau yog xoom. Los ntawm cov kev poob ntawm cov fiber, 1.31 μm tsuas yog lub qhov rais qis ntawm cov fiber. Nyob rau hauv txoj kev no, 1.31 μm wavelength cheeb tsam tau dhau los ua haujlwm zoo tagnrho rau lub qhov rais fiber ntau, thiab nws kuj yog lub qhov rai tsis muaj zog rau cov khoom siv kho tshiab. Cov ntsiab lus tseem ceeb ntawm 1.31 μm pa puv-hom fiber ntau yog txiav txim siab los ntawm International TT-T Hauv G652 cov lus pom zoo, yog li cov fiber no hu ua G652 Fiber.

Ntaus	Tseem ceeb nominal diaminal	Kev Sib Kis	Jumper xim
Ib-Hom	8/125 μm lossis 9/125 μm lossis 10/125 μm	Cov kev ncua deb, txog li ntau pua mais	Feem ntau daj, lub thawv txuas txuas npog yog xiav
Ntau txiag	50/125 μm European Txuj Kev	Luv luv nrug, feem ntau tsis pub dhau 2km	Feem ntau txiv kab ntxwv, qee qhov siv grey, thiab lub thawv tiv thaiv lub thawv tiv thaiv yog beige lossis xim dub

Daim ntawv ceeb toom:

1. Tsis txhob khoov thiab voj lub fiber ntau dhau thaum siv, uas yuav nce cov kev ua kom lub teeb thaum sib kis thiab rhuav cov pigtail ntawm lub qhov ntswg.

2. Tom qab siv cov tshuaj pleev xim zoo nkauj, nco ntsoov tiv thaiv cov tshuab hluav taws xob optical fiber ntau ntxiv, thiab cov pa rov qab los yuav plam qhov kev ntsuas ntawm lub cev.

3. Qhov kev hloov pauv ntawm lub ntsej muag ntawm lub fiber ntau ntawm cov fiber ntau yuav tsum yog qhov zoo ib yam, qhov kawg ntawm lub ntsej muag hloov kho kho qhov muag nrog lub wavelength. Txoj kev yooj yim kom paub qhov txawv yog tias cov xim ntawm cov khoom siv kho qhov muag yuav tsum zoo ib yam.
