Tus qauv ntawmoptical fiber ntaukev sib txuas lus cables yog txiav txim siab los ntawm ntau yam, nrog rau lawv lub hom phiaj kev sib kis, kev ua haujlwm ib puag ncig, thiab txoj kev tso. Hais lus dav dav, feem ntau siv optical fiber ntau cables tau muab faib ua ob pawg tseem ceeb: sab hauv tsev kho qhov muag cables thiab sab nraum zoov kho qhov muag cables. Tshooj lus no feem ntau qhia txog cov kab hluav taws xob sab nraum zoov.
Cov qauv thiab hom Optical Cables
◇Fiber optic cable hom, xim code thiab kawg hom
Cov txheej txheem yooj yim ntawm cov kab hluav taws xob sab nraum zoov suav nrog kev tso tseg, lub hauv paus raj, thiab cov pob txha pob txha. Txhua tus qauv yooj yim tuaj yeem ua raws li ob qho tib si faib cov fibers thiab ribbon optical fibers. Lawv cov yam ntxwv tau piav qhia hauv qab no:
stranded optical cable
Lub ntsej muag kawg thiab cov khoom tiag tiag ntawm txoj hlua kho qhov muag tau pom nyob rau hauv daim duab 2-20 thiab 2-21. Cov qauv ntawm cov hlua kho qhov muag uas tau tso tseg yog raws li hauv qab no: ntau yam thib ob -coated optical fiber xoob hlab (los yog ib nrab cov hlua) tau tso tseg nyob ib ncig ntawm lub hauv paus hlau txhawb cov tswv cuab los ua ib lub voj voog cable. Cov tub ntxhais cable yog thawj zaug qhwv nrog cov ntaub nplaum nplaum nplaum thiab tom qab ntawd nrog polyethylene puab sheath, ua raws li longitudinally qhwv nrog dej-thaiv daim kab xev thiab ob-sided coated corrugated steel (aluminium) daim kab xev, thiab thaum kawg nrog ib tug polyethylene txheej sheath.
Daim duab 2-20 qhia txog lub ntsej muag kawg ntawm ib qho khoom siv kho qhov muag.
Cov yam ntxwv ntawm stranded optical cables yog: ib tug loj tus naj npawb ntawm optical fibers muaj nyob rau hauv lub cable, qhov ntev fiber ntau yog yooj yim los tswj, lub cable muaj zoo mechanical thiab ib puag ncig kev ua tau zoo, thiab nws yog haum rau faus ncaj qha faus, duct nteg, thiab kuj yuav siv tau rau aerial nteg.
Central tube optical cable
Raws li pom nyob rau hauv daim duab 2-22 thiab 2-23, cov qauv ntawm lub hauv paus raj optical cable muaj ib tug thib ob optical fiber xoob raj los yog ib tug kauv optical fiber.
Lub hauv paus raj hom kho qhov muag cable, raws li qhia nyob rau hauv daim duab hauv qab no, muaj cov qauv hauv qab no: ib qho kev kho qhov muag fiber ntau xoob raj los yog ib qho kauv optical fiber xoob raj, muab tso ncaj qha rau hauv nruab nrab ntawm lub cable tsis muaj twisting; longitudinally qhwv nrog dej- thaiv daim kab xev thiab ob npaug - sab yas-coated steel (aluminium) daim kab xev; thiab ob qho tib si txhawb nqa puag ncig phosphated carbon steel hlau lossis fiberglass rods nyob hauv ib lub hnab polyethylene. Nyob ntawm seb lub raj xoob puas muaj cov khoom siv kho qhov muag cais, ib qho khoom siv kho qhov muag, lossis ib qho khoom siv kho qhov muag, cov raj hauv nruab nrab hom kho qhov muag cables raug cais raws li cais fiber ntau hauv nruab nrab tube cables lossis optical fiber ribbon central tube cables, thiab lwm yam.
Qhov zoo ntawm central tube optical cables yog cov qauv yooj yim, txheej txheem tsim khoom yooj yim, me me hla-section, thiab lub teeb yuag, ua rau lawv haum rau saum huab cua thiab tseem siv tau rau [lwm daim ntawv thov].
Nws tuaj yeem muab tso rau hauv ducts lossis ncaj qha faus. Qhov tsis zoo ntawm central tube optical cables yog tias tus naj npawb ntawm cov fiber ntau optical hauv lub cable yuav tsum tsis txhob muaj ntau dhau (xws li 12 cores rau ib qho kev faib fiber ntau, 36 cores rau ib pob fiber ntau, thiab 216 cores rau fiber ntau ribbon), tsis txaus cua txias ntawm lub raj xoob thaum lub sij hawm xoob lub raj extrusion txheej txheem, kev ua tiav ntawm txoj hlua khi, thiab kev ua tiav ntawm txoj hlua khi. fiber ntev nyob rau hauv optical cable.
skeleton optical cable
Tam sim no, cov pob txha- hom kho qhov muag cables hauv Suav teb raug txwv rau qhuav- hom ribbon fiber ntau cables. Qhov no suav nrog muab cov kab hluav taws xob kho qhov muag tso rau hauv ib qho matrix hauv U-zoo li tus lossis SZ- zoo li tus kauv skeleton grooves, nrog dej- thaiv daim kab xev qhwv ib ncig ntawm lub cev pob txha los tsim ib kab noj hniav kaw. Thaum dej- thaiv daim kab xev los rau hauv dej, nws nqus dej thiab nthuav dav, tsim kom muaj dej- thaiv cov gel barrier. Ib ob -sab yas{11}}coated steel daim kab xev yog ces nyob rau hauv longitudinally qhwv ib ncig ntawm dej- thaiv daim kab xev, thiab thaum kawg, ib tug polyethylene txheej sheath ntxiv.
Qhov zoo ntawm lub cev pob txha- hom fiber ntau optic ribbon cables yog: cov qauv compact, me me cable txoj kab uas hla, siab fiber ntau ntom (txog mus rau txhiab tus cores), tsis tas yuav tshem dej- thaiv cov roj thaum lub sij hawm splicing, thiab siab splicing efficiency. Qhov tsis zoo yog: cov cuab yeej tsim khoom siv yooj yim (yuav tsum tau muaj cov kab mob pob txha pob txha), ntau cov txheej txheem, thiab kev tsim khoom nyuaj.
