Armored fiber optic cable tsuas yog ib txwm fiber ntau nrog txheej hlau - hlau lossis txhuas- qhwv ib ncig ntawm cov tub ntxhais. Nws txwv cov khoom los ntawm crushing, zom, los yog ua kom puas koj cov cable. Cov ntaub ntawv chaw, tsev kawm ntawv khiav, factories, nyob qhov twg txoj kev tau rough.
Yog tias koj twb paub cov hauv paus ntsiab lus thiab tsuas yog xav tau xaiv hom zoo, hla mus rau lub rooj sib piv. Txwv tsis pub, ntawm no yog li cas cov cables muab tso ua ke thiab qhov twg txhua yam ua rau kev nkag siab.
Yuav ua li cas Armored Fiber Cable yog tsim
Pib los ntawm sab nraud thiab ua haujlwm hauv. Lub tsho sab nrauv yog polyethylene rau sab nraum zoov cable, PVC lossis LSZH rau sab hauv tsev. Hauv qab ntawd zaum ib txheej ntawm aramid yarn rau tensile lub zog thaum rub. Ces lub armor. Nyob rau hauv lub armor, cov fibers nyob rau hauv nruj- cov hlab tsis los yog xoob hlab nyob ntawm daim ntawv thov.
Feem ntau ntawm qhov ntawd zoo ib yam rau lwm yam fiber ntau cable. Cov neeg feem ntau nyiam gloss tshaj yog kev sib raug zoo ntawm hom armor thiab tsis siv, vim hais tias nws cuam tshuam li cas koj tau txiav tawm cable ntawm qhov chaw. Sab hauv armored cables siv nruj- buffered fiber ntau ntawm 900µm ib strand-koj tuaj yeem tsocov khoom sib txuastxoj cai ntawm cov thiab hla furcation nkaus, uas yog qhov zoo. Sab nraum zoov armored cables mus nrog xoob- raj siv, fibers ntab hauv gel lossis qhuav- thaiv cov khoom hauv cov raj loj dua. Qhov ntawd ua haujlwm kub hloov pauv tau zoo dua (koj feem ntau ntsuas qis rau -40 degree), tab sis koj yuav tsum tau furcate ua ntej koj txuas, thiab qhov ntawd yog ib kauj ruam ntxiv tsis muaj leej twg nyiam ua hauv thaj tsam ntawm 7 AM.
Txawm koj tab tom khiavsingle-mode lossis multimodeyog ib lo lus nug tag nrho los ntawm cov cuab yeej cuab tam. Tib - hom rau kev ncua deb thiab bandwidth, multimode rau luv luv txuas. Lub armor tsis kov optical kev ua tau zoo.
Aluminium Interlock vs. Corrugated Steel: Hom Armor Koj Puas Xav Tau?
| Feature | Interlocking Aluminium Armor (AIA) | Corrugated Steel Daim kab xev Armor |
|---|---|---|
| Nws ua li cas | Aluminium strips raug mob helically, sib tshooj | Coated steel daim kab xev folded rau hauv ib lub raj kaw |
| Crush tsis kam | Nruab nrab. Kev taug kev ko taw, cov thawv ntim khoom, qee zaus ntaiv rub | Siab. Direct faus, cov cuab yeej siv hnyav |
| Kev tiv thaiv nas | Ib nrab - qhov sib txawv ntawm cov ntaub qhwv tuaj yeem siv tau | Siv tau. Nruam raj, tsis muaj cov ntsiab lus nkag |
| Qhov hnyav | Txog ib nrab ntawm qhov hnyav ib 'meter' ntawm steel kab xev | hnyav dua. Ib tug 24-fiber cable khiav roughly 2x lub txhuas version |
| Yooj yim | Routes yooj yim los ntawm cable tais thiab ib ncig ntawm cov ces kaum | Nyuaj, loj qhov tsawg kawg nkaus khoov vojvoog |
| Kev ntsuas hluav taws | Riser (OFCR), Plenum (OFNP), LSZH | Sab nraum zoov ntsuas nkaus xwb, feem ntau |
| Nws mus qhov twg | Cov ntaub ntawv chaw, risers, qhib qab nthab khiav, tsev kawm ntawv txoj hauv kev | Direct faus, duct khiav, muaj sab nraum zoov, hnyav ib puag ncig |
Rau kev ua haujlwm sab hauv tsev hauv North America, aluminium interlock dominates. Cov chaw zov me nyuam, tsev kho mob IT closets, tsoom fwv tsev, tsev kawm ntawv risers-nws nyob txhua qhov chaw. Lub helical qhwv muab lub cable txaus flex rau txoj hauv kev los ntawm cov tais thiab J-hooks yam tsis tau tig txhua qhov khoov rau hauv kev sib tw sib tw.
Nov yog qhov uas tsis tau tham txog txaus: aluminium interlock tuaj yeem tshem tawm cov kav dej ntawm ntau qhov kev khiav hauv tsev. Hloov chaw ib txwm ob- kauj ruam- nruab cov kav dej, tom qab ntawd rub lub cable- koj tsuas yog khiav lub armored cable raws tus ntaiv khib lossis hla lub qab nthab ncaj qha. Ntawm ib lub tsev nrog 30 lossis 40 khiav, uas yog hnub tawm ntawm lub sijhawm, tsis yog teev. Nws kuj tseem muaj cov kev ntsuam xyuas plenum thiab riser, uas tseem ceeb vim tias ntau ntawm cov kev khiav no mus txog huab cua- tuav qhov chaw.
Tab sis aluminium interlock tsis yog nas tiag tiag - pov thawj. Peb yuav tsum paub meej txog qhov ntawd. Lub helical wraps sib tshooj, tab sis muaj qhov sib txawv txaus uas tus squirrel txiav txim siab los yog nas yuav zom los ntawm. Kuv twb pom tom qab. Yog tias lub xaib muaj cov ntaub ntawv keeb kwm yav dhau los, tsis txhob xav txog nws - mus ncaj nraim rau corrugated steel.
Corrugated steel daim kab xev tsim ib lub raj kaw nrog xoom qhov khoob. Nws yog qhov koj xav tau rau kev ncaj qha - faus neeg khiav, duct installation ntawm cov tsev, thiab cov chaw lag luam -refineries, mines, manufacturing floors- qhov twg koj tab tom soj ntsuam cov tshuaj, kev co, thiab forklifts. Lub cable yog hnyav thiab tawv, uas ua rau nws mob rau kev nruj sab hauv tsev, tab sis underground los yog hauv ib lub cable trough uas tsis muaj teeb meem txhua. Lub corrugation kuj muab rau koj ib tug dlej noo barrier, uas yog ib feem ntawm vim li cas nws ua hauj lwm rau faus txawm nyob rau hauv ntub av tsis tas yuav tsum tau ib tug nyias innerduct.
Rau cov khoom hnyav heev- submarine landings, hla dej- muaj cov tshwj xeeb steel hlau armor thiab braided armor variants ua rau ntau dua tensile loads dua daim kab xev armor tuaj yeem ua tau. Tab sis qhov ntawd yog kev sib tham sib txawv.
Sab hauv tsev, Sab nraum zoov, thiab Sab Hauv Tsev / Sab nraum zoov Cable
Sab hauv armored cable: nruj-buffer fiber, interlocking aluminium armor, nplaim taws-cov tsho tiv thaiv. Sab nraum zoov: xoob- raj fiber ntau, corrugated steel, dej- thaiv cov tebchaw. Yooj yim txaus.
Ib qho uas tau tshwm sim ntau thiab ntau dua ntawm cov phiaj xwm hauv tsev kawm ntawv yog sab hauv / sab nraum zoov- ntsuas armored cable. Lub suab yog koj khiav ib lub cable los ntawm sab nraud duct nkag, los ntawm lub tsev nkag mus rau hauv lub riser, mus rau hauv lub telecom chav tsev - tsis muaj splice ntawm lub tsev nkag point. Qhov ntawd yog ib qho tsawg dua splice enclosure rau ib qho kev hloov pauv, ntxiv rau tag nrho cov haujlwm tom qab nws. Rau ib lub tsev kawm ntawv uas muaj 10 lossis 15 lub tsev, nws ntxiv nrawm. Cov cables no feem ntau ua ke xoob-tube fiber ntau nrog LSZH lossis riser tsho thiab aluminium interlock armor.
Vim li cas thab nrog Tus Nqi Ntxiv?
Armored cable khiav 20 mus rau 40 feem pua ntau tshaj qhov sib npaug tsis muaj armored cable, yog li koj xav tau ib qho laj thawj.
Cov nas. Qhov ntawd yog vim li cas, thiab nws tsis txawm nyob ze. Ib qho zom- dhau ntawm kev khiav hauv tsev kawm ntawv tsis muaj phom sij txhais tau hais tias lub tsheb thauj neeg mob ceev ceev, kev sib txuas thev naus laus zis, khoom siv tshiab, thiab txawm li cas los xij ntau teev lossis hnub poob qis thaum koj tos txhua yam uas tuaj koom ua ke. Ib daim nqi kho mob yuav luag ib txwm tshaj li qhov koj yuav tau siv kho kom zoo dua tag nrho txoj hauv kev mus rau armored. Yog li cov chaw uas tau dhau los ntawm nws ib zaug?
