Nyob rau hauv Internet era, optical cables yog indispensable ntaub ntawv rau kev tsim kho ntawm optical kev sib txuas lus infrastructure. Raws li deb li optical cables muaj kev txhawj xeeb, muaj ntau pawg, xws li fais fab kho qhov muag cables, underground optical cables, mining optical cables, nplaim-retardant optical cables, underwater optical cables, thiab lwm yam. Hauv tsab xov xwm no, peb yuav muab cov lus teb yooj yim paub txog yuav ua li cas xaiv adss optical cable. Thaum xaivadss optical fiber ntau cabletsis, peb yuav tsum xaiv qhov tseeb adss optical cable chaw tsim tshuaj paus. Cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau qhov chaw:
1: Optical fiber ntau
Cov tuam txhab kho qhov muag tsis tu ncua feem ntau siv A-qib fiber ntau cores los ntawm cov tuam txhab loj. Qee cov khoom siv kho qhov muag qis thiab qis qis feem ntau siv C-qib, D-qib kho qhov muag fibers thiab smuggled optical fibers uas tsis paub keeb kwm. Cov fibers kho qhov muag no muaj qhov chaw nyuaj thiab tau tawm ntawm lub Hoobkas rau lub sijhawm ntev, thiab feem ntau ntub. Discoloration, thiab ib hom optical fiber ntau feem ntau tov nrog ntau hom optical fiber. Txawm li cas los xij, cov chaw tsim khoom me feem ntau tsis muaj cov cuab yeej ntsuas tsim nyog thiab tsis tuaj yeem txiav txim siab qhov zoo ntawm fiber ntau optical. Vim hais tias xws li fibers optical tsis tuaj yeem paub qhov txawv ntawm qhov muag liab qab, cov teeb meem tshwm sim thaum lub sij hawm tsim kho yog: nqaim bandwidth thiab kev sib kis luv luv; tsis sib luag thickness thiab tsis muaj peev xwm txuas nrog pigtails; tsis muaj qhov yooj ntawm optical fibers thiab tawg thaum coiled.
2. Reinforced steel hlau
Cov hlau xaim ntawm cov kab hluav taws xob sab nraum zoov los ntawm cov chaw tsim khoom niaj hnub yog phosphated thiab muaj qhov grey nto. Cov hlau zoo li no yuav tsis nce hydrogen poob, yuav tsis xeb, thiab muaj zog siab tom qab raug cabled. Inferior optical cables feem ntau yog hloov nrog nyias hlau hlau los yog txhuas hlau. Txoj kev txheeb xyuas tau yooj yim vim tias lawv tshwm dawb thiab tuaj yeem khoov ntawm lub siab thaum tuav hauv tes. Optical cables uas tsim nrog xws li cov hlau hlau muaj hydrogen loj poob. Sij hawm dhau mus, ob qhov kawg uas lub thawv fiber ntau tau dai yuav xeb thiab tawg.
3. Sab nrauv
Cov kab hluav taws xob sab hauv tsev feem ntau siv polyethylene lossis nplaim hluav taws-retardant polyethylene. Cov tsos yuav tsum du, ci, saj zawg zog, thiab yooj yim tev tawm. Cov txheej txheej ntawm cov khoom siv kho qhov muag tsis zoo muaj qhov tsis zoo thiab ua rau nws ua rau lub tes tsho nruj thiab aramid fibers sab hauv.
PE sheath ntawm sab nraum zoov optical cables yuav tsum tau ua los ntawm high-zoo dub polyethylene. Tom qab lub cable tsim, cov txheej txheej yuav tsum du, ci, uniform hauv tuab, thiab tsis muaj npuas me me. Cov txheej txheej ntawm cov khoom siv kho qhov muag tsis zoo feem ntau yog tsim los ntawm cov khoom siv rov ua dua tshiab, uas tuaj yeem txuag tau ntau tus nqi. Cov txheej txheej ntawm xws li optical cables tsis du. Vim hais tias muaj ntau yam impurities nyob rau hauv cov ntaub ntawv raw, lub sheath ntawm lub tiav lawm optical cable muaj ntau heev me me pits. Nyob rau tib lub sijhawm, nws yuav tawg thiab txhim kho. dej.
4. Aramid
Kuj tseem hu ua Kevlar, nws yog cov tshuaj fiber ntau muaj zog uas tam sim no siv hauv kev lag luam tub rog. Cov kaus mom hlau tub rog thiab cov tsho tiv thaiv mos txwv yog tsim los ntawm cov khoom siv no. Tam sim no, tsuas yog DuPont thiab Aksu ntawm Netherlands tuaj yeem tsim tau hauv ntiaj teb, thiab tus nqi yog kwv yees li ntawm 300,000 ib tuj. Cov kab hluav taws xob sab hauv tsev thiab lub zog hluav taws xob hluav taws xob hluav taws xob hluav taws xob (ADS ua li cas txiav txim siab qhov zoo ntawmadss kho qhov muag cables) siv aramid yarn li reinforcement. Vim yog tus nqi siab ntawm aramid, cov kab hluav taws xob sab hauv tsev tsis zoo feem ntau muaj qhov nyias nyias, yog li siv cov strands tsawg dua ntawm aramid kom txuag tau cov nqi. Xws li optical cables tau yooj yim tawg thaum hla cov kav dej. ADSS optical cables feem ntau tsis twv kom txiav cov ces kaum vim tias tus nqi ntawm aramid fiber ntau siv hauv cov khoom siv kho qhov muag yog txiav txim siab raws li qhov ncua sij hawm thiab cua ceev ib ob.
Cov saum toj no yog ob peb yam tsis zoo rau kev txiav txim qhov zoo ntawm optical cables thaum xaiv adss optical cables. Kuv vam tias lawv tuaj yeem ua tus siv rau peb cov neeg siv khoom thiab cov phooj ywg. Yog tias koj txaus siab rau peb cov khoom lossis xav tau peb cov kws tshaj lij kev pabcuam, thov koj xav tiv tauj peb!
