Hardly -txhais kev cai rau lub vojvoog khoov ntawm optical fibers
Static dabtsi yog khoov vojvoog (lub xeev ruaj khov tom qab ua tiav): Ntau dua lossis sib npaug li 10 npaug ntawm tag nrho cov kab uas hla ntawm cov kab hluav taws xob kho qhov muag. Lub ntsiab lus: Thaum txoj kab kev tsim kho tiav thiab tseem nyob ruaj khov rau lub sijhawm ntev, qhov tsawg kawg nkaus lub vojvoog ntawm tag nrho cov arc khoov thiab qhov seem ntawm lub voj voog ntawm coiling tsis tuaj yeem qis dua 10 npaug ntawm qhov tuab ntawm cov khoom siv kho qhov muag.
Dynamic dabtsi yog khoov vojvoog (kev tsim rub tawm, khoov ib ntus thaum lub sijhawm teeb tsa cov yeeb nkab): Cov txheej txheem nyuaj Ntau dua lossis sib npaug li 20 npaug ntawm tag nrho cov kab nruab nrab ntawm qhov kho qhov muag. Lub ntsiab lus: Thaum lub sij hawm cov txheej txheem xws li cov yeeb nkab ntxig, rub tawm, khaws cia ib ntus, thiab kev thauj mus los thiab rub tawm, cov khoom siv kho qhov muag yuav tsis tu ncua raug quab yuam thiab deformation. Rau kev khoov ib ntus, cov npoo ntawm yam tsawg kawg ib zaug ntawm qhov qub yuav tsum tau muab los tiv thaiv cov tub ntxhais fiber ntau los ntawm kev puas tsuaj tam sim ntawd thaum rub. Rau qhov kho qhov muag cable nrog ib txoj kab uas hla ntawm 10 hli, thaum lub sij hawm tsim kho, qhov tsawg kawg nkaus khoov vojvoog yuav tsum ncav cuag 200 hli. Nws yog nruj me ntsis txwv tsis pub yuam kom nyem thiab nqaim lub arc ntawm cov yeeb nkab ces kaum thaum lub yeeb nkab ntxig.
Optical fibers kaw cov teeb liab kho qhov muag los ntawm qhov sib txawv ntawm qhov ntsuas refractive ntawm cov tub ntxhais thiab cov cladding. Lub teeb yog kiag li kaw nyob rau hauv lub tub ntxhais thiab kis mus rau pem hauv ntej. Thaum lub vojvoog dabtsi yog khoov me me dhau thiab ze rau qhov tuag fold, hom leakage tshwm sim: qhov kho qhov muag cable yog khoov heev, ua rau muaj qhov sib txawv tseem ceeb hauv txoj kev kho qhov muag hauv qhov tseem ceeb; lub teeb teeb liab thaum xub thawj nyob rau hauv cov tub ntxhais tawg los ntawm cladding thiab scatters thiab dissipates sab nraud; ib tug loj npaum li cas ntawm lub teeb liab xau los ntawm qhov khoov taw tes, ncaj qha ua rau ib tug tseem ceeb nce nyob rau hauv kab attenuation; ntev - lub sij hawm nruj bending nrog ib lub vojvoog me me ua rau cov kab nrib pleb hauv lub khob iav, thiab lub sij hawm ntev dua, qhov poob loj dua, nws thiaj li ua rau lub teeb tsis tiav. Cov lus ceeb toom tseem ceeb: Cov micro- cov kab nrib pleb no pom tsis pom qhov muag liab qab. Tam sim no fusion splicing thiab lub teeb kis tau tus mob yog tag nrho. Txawm li cas los xij, tom qab qhov kub thiab txias hloov, kev vibrations, thiab dej los nag, qhov kev phom sij zais cia tau tshwm sim thiab nyuaj heev los nrhiav thiab daws teeb meem.
Ntawm - qhov kev npaj tsim kho qhov chaw, yooj yim ua tau raws li cov qauv kev khoov lub vojvoog
1. Cable routing: Tshwj xeeb loj- vojvoog nkhaus kav yog siv los hloov txoj cai -lub luj tshib ntawm PVC thiab PE cable conduits rau khoov. Tag nrho cov loj- cov kav dej nkhaus lossis cov kav dej txuas ntxiv raug xaiv kom tsis txhob muaj kev sib txuas ncaj nraim 90-degree; Buffer arcs yog tshwj tseg rau qhov nkag thiab tawm ntawm cov thawv tsis muaj zog tam sim no thiab cov thawv dej tsis muaj dej, thiab lawv tsis ncaj qha rau ntawm lub thawv lub cev hauv qhov nyuaj.
2. Cable tais / kab slots tig: Arc hloov pauv accessories yog ntsia ntawm txoj hauj lwm tig ntawm cov hlau cable tais thiab cov kab yas. Kev sib txuam arc hloov pauv fittings yog muab los xyuas kom meej tias cov kab hluav taws xob sab hauv ua tau raws li cov qauv arc vojvoog; Ntau txheej ntawm cov kab hluav taws xob tau teem caij sib cais, yam tsis muaj kev sib tsoo los yog sib tsoo, kom tsis txhob qis dua - cov kab hluav taws xob kho qhov muag tau raug compressed hnyav thiab muaj me me bending radii.
3. Tshem tawm cov kab hluav taws xob ntau dhau: Cov cables uas tseem tshuav rau hauv chav tshuab, qhov tsis muaj zog tam sim no, thiab lub thawv dej tsis zoo sab nraum zoov yog cov kab mob sib npaug rau hauv lub voj voog loj nrog txoj kab uas hla ntawm ntau tshaj 20 cm. Cov ntaub nplaum mos mos yog xoob ruaj, thiab ntau txheej txheej ntawm kev sib tshooj thiab nyem yog txwv tsis pub.
4. Sab nraum zoov nyiaj siv ua haujlwm thiab sab nrauv kab poob dej khoov tus qauv: Rau sab nraum zoov cables nkag mus thiab tawm ntawm phab ntsa, cov khoom siv lub thawv, thiab lwm yam., ib qho yooj yim drip dej khoov yog ua downward. Lub vojvoog arc tsis tsawg dua 10 npaug ntawm txoj kab uas hla sab nraud ntawm cov kab hluav taws xob kho qhov muag, uas tsis yog tsuas yog tiv thaiv cov dej ntws tawm xwb tab sis kuj zam me me - lub kaum sab xis khoov.
5. Kev khi thiab kho: Tsuas yog siv cov hlua khi mos. Xaiv daim txhuam cev-coated binding tapes, nylon soft binding tapes. Tom qab khi, ib qho me me ntawm qhov chaw txav tau khaws cia. Kev khi yuav tsum tsis txhob muab xauv, nruj, los yog compressed kom lub qhov muag cable deform.
