Dab tsi yog qhov feem ntau cov tshuaj pleev roj fiber ntau?

Feem ntau hom fiber ntau - Qhov optic cable yog OM3 thiab OM4 multimode cables. Siv dav hauv cheeb tsam hauv nroog, cov ntaub ntawv cov ntaub ntawv thiab lwm yam kev sib txuas lus luv luv. Txawm li cas los xij, tib hom cable Cable ua lub luag haujlwm tseem ceeb hauv caj qaum kis las thiab kev sib txuas lus sib cuam tshuam ntawm ntev- deb kev kis. Ntawm no yog saib ntawm feem ntau hom fiber ntau {{}} optic cable:
I. Los ntawm hom kev thauj: ib hom kev thauj mus los thiab cov multimode
Ib Leeg - hom cable
Nta: Me fiber ntau cov tub ntxhais txoj kab uas hla (txog 8}}}}} 1 microns kev sib kis (kaum rau ntau pua mais kev).
Daim ntaub ntawv: intercity pob txha network, submarine cable, 5g hauv paus chaw nres tsheb thiab lwm yam kev sib txuas lus tej thaj chaw deb.
Hom Hom: G.652 (Affect Ib - hom) thiab g.655 (tsawg}} {}} hom).
Ntau Ntau Cable
Nta: Loj Fiber Tore Code (50 lossis 62,5 microns), haum rau multimode teeb kis. Txawm li cas los xij, kev sib nrug deb yog luv dua (feem ntau ob peb puas metres rau 2 mais) thiab tsawg dua. Daim ntawv thov cov xwm txheej: Luv luv - deb nrug kev sib txuas lus xws li cov ntaub ntawv ua kev sib txuas lus, thaj chaw sib txuas, lub tsev kawm ntawv network, thiab lwm yam.
Siv feem ntau:
Om1: 62.5 micron cov tub ntxhais uas hla, txhawb nqa 100mbps rau 1 Gbps kis, theem- tawm.
OM2: Core txoj kab uas hla 50 microns, txhawb 1 gbps mus rau 10 Gbps mus kis, haum rau cov neeg muaj cai thaum ntxov.
OM3: 50 micron cov tub ntxhais txoj kab uas hla nrog rau 10 Gbps kis (txog 100m) yog qhov kev xaiv thawj rau cov ntaub ntawv cov ntaub ntawv.
OM4: 50 micron cov tub ntxhais uas hla, txhawb 10GBs mus rau 100 Gbps kis (txog 150m), haum rau cov chaw ua haujlwm tuab.
Om5: Cov kab uas hla ntawm 50 micron nrog kev txhawb nqa rau luv- wavel} wavel} wavel} wavel} Wavel} Wavel} Wavel} Wavel} Wavel} Wavel} Wavel} Wavel} Wavel} Lub Gultage mus txog 400 GBPS kis.
ii. Los ntawm cov qauv: stranded thiab Central raj vs. tub cab core
Fiber ntau Optic Cable
Tus qauv: Ntau cov fibers yog qhwv hauv cov xoob xoob ib ncig ntawm lub zog nruab nrab thiab tom qab ntawd muaj pov thawj. Nta: High tensile lub zog, zoo heev khoov tsis kam, haum rau ntev- deb} kev sib tshooj lossis cov raj xa hluav taws xob.
Daim Ntawv Thov: Telecoms, Xov Xwm, Cov Khoom Sib Txuas Lus Nyob deb nroog.
Central Tube Optical Cable
Cov qauv: Fiber bundles lossis ribbons tau muab tso rau hauv nruab nrab raj thiab sab nraud cov tswv cuab muab tso rau hauv parallel.
Nta: Cov qauv yooj yooj yim, lub teeb yuag, haum rau kev ncua deb ntawm kev faus neeg lossis sib dhos.
Cov Ntawv Thov: Cov Chaw Teev Cov Ntaub Ntawv, Chaw Lag Luam Tuam Tsev Kawm Ntawv, Kev Siv Tes Taw.
Board - hom kho qhov cub
Cov qauv: fiber ntau cov fiberers phetedded nyob rau hauv lub tsho kauv muab kauv cable.
Nta: kev siab siab siab kuj, haum rau high - qhov chaw ntom ntom lossis cov chaw ib puag ncig.
Siv: Submarine cov khoom siv kho qhov muag, kev tswj network.
III. Los ntawm daim ntawv thov: Sab hauv tsev vs. Sab Nraum Sab Nraum Ntxiv rau cov neeg ua haujlwm tshaj lij
Sab hauv kho qhov muag cable
Nta: lub plhaub yog ua los ntawm pvc lossis qis {{- Halogen {{free cov khoom siv tab sis muaj zog tensile tab sis qis tensile.
Lub Hom Phiaj: Hom Broadband, chaw ua haujlwm cabling, cov ntaub ntawv lub chaw sib txuas sib txuas. Sab Nraum Zoov Optic Cable
Nta: polyethylene lossis steel straps txheej, waterproof, anti {{{} rat, anti {{UCH.
Siv: Lub nroog raj xa dej, overhead rajpeline, ncaj beet pipeline.
TSHWJ XEEB CABLINE
Hom: suav nrog cua - tshuab tawg (micro cables), cleshet hluav taws xob (opgw / s sensor cables.
Daim ntaub ntawv thov: HV kis cov kab, roj xa xov hlau, muaj tswv yim thauj khoom ntse, thiab lwm yam ..
