Nyob rau hauv lub ntiaj teb no ntawm sab nraum cov nroj tsuag fiber ntau tes hauj lwm, lub splice kaw yog feem ntau kho raws li ib tug afterthought. Nws zaum hauv qab ntawm daim nqi ntawm cov ntaub ntawv, sib tw ntawm tus nqi, thiab tsis tshua muaj cov ncauj lus kom ntxaws txog kev sib cav tswv yim. Txawm li cas los xij, lub npov tsis txaus ntseeg no yog qhov cuam tshuam feem ntau hauv koj ODN-vim thaum nws ua tsis tiav, txhua yam ua tsis tiav nrog nws.
Cov dej nkag, foob degradation, fiber ntau, thiab cov khoom siv qaug zog tsis tshwm sim thaum hmo ntuj. Lawv tshwm sim maj mam, invisibly, thiab cumulatively. Kev kaw uas yog "zoo txaus" ntawm kev xa mus ua lub hauv paus ntawm kev saib xyuas mob taub hau peb xyoos tom qab. Txij thaum ntawd los, kev txuag nyiaj los ntawm kev xaiv cov kev xaiv pheej yig dua tau siv tag nrho- thiab tom qab ntawd qee qhov ntawm - los ntawm cov tsheb thauj khoom, kho xwm txheej ceev, thiab cov qhab nia pabcuam.
Cov lej qhia ib zaj dab neeg sobering. Kev lag luam thoob ntiaj teb Fiber Optic Splice Closures (FOSC) tau kwv yees kwv yees li US $ 871 lab hauv 2025 ** thiab tau kwv yees kom ncav cuag ** US $ 1,162 lab los ntawm 2032, loj hlob ntawm CAGR ntawm 4.3%. Lwm qhov kev kwv yees tso lub lag luam siab txog $ 1.86 nphom hauv 2025 **, nrog kev kwv yees nce mus txog ** US $ 3.64 nphom los ntawm 2033 ntawm CAGR ntawm 8.72%. Qhov kev loj hlob no- tau tsav los ntawm FTTH nthuav dav, 5G fronthaul, thiab cov ntaub ntawv chaw sib cuam tshuam - txhais tau tias kaum tawm txhiab tus tshiab raug kaw txhua xyoo. Txhua tus sawv cev rau qhov kev txiav txim siab: nqis peev hauv qhov zoo tam sim no, lossis them nyiaj kho tom qab.
Dab tsi cais lub network uas kav ntev los ntawm ib qho uas ua tsis tiav ntxov tsis yog cov fibers lossis cov khoom sib txuas - nws yog qhov kev txiav txim siab ua nyob rau ntawm qhov chaw uas fibers tau koom nrog thiab tiv thaiv. Nov yog dab tsi network planners, procurement managers, thiab engineers yuav tsum paub txog kev xaiv splice kaw uas txo ntev -lub sij hawm OPEX.
Vim li cas "Zoo txaus" Tsis zoo txaus
Kev kaw qhov sib txuas yog siv ib zaug thiab xav tias yuav ua tau rau 10 mus rau 15 xyoo lossis ntau dua. Tsis zoo li cov khoom siv nquag, nws tsis tuaj yeem saib xyuas los yog hloov kho tau yooj yim. Thaum nws raug kaw thiab muab faus, tus nqi ntawm kev cuam tshuam yog ntsuas tsis yog nyiaj daus las tab sis nyob rau hauv daim ntawv tso cai excavation, neeg coob coob, thiab kev cuam tshuam kev pabcuam.
Xav txog kev lag luam. Ib qho kev kaw ib leeg tsis ua haujlwm los ntawm cov dej nkag tuaj yeem cuam tshuam cov kev pabcuam rau ntau pua tus neeg siv, ua rau OPEX nce ntxiv. Cov ntaub ntawv teb tau lees paub tias dej nkag yog qhov ua rau ntau tshaj plaws ntawm ODN teb tsis ua haujlwm. Nws ua rau hydrogen poob hauv optical fibers, corrodes hlau Cheebtsam, thiab degrades splice kev ua tau zoo nyob rau lub sij hawm. Thaum cov dej nkag mus, qhov kaw yuav ua rau lub kaw lus kaw kom qeeb, irreversible degradation.
Qhov no tsis yog qhov tshwm sim tsawg. Cov kev tshawb fawb pom tau tias ntau dua 60% ntawm cov nroj tsuag sab nraud tsis ua haujlwm yog vim muaj dej noo thiab lub cev puas tsuaj. Remarkably, 73% ntawm network outages stem los ntawm kev tiv thaiv cable teeb meem. Thaum qhov kev kaw tsis ua tiav, qhov trench tau khawb dua - ntawm tus nqi tib yam li kev xa tawm thawj zaug, ntxiv rau kev ua haujlwm ntawm re- splicing, kuaj, thiab resealing.
Cov txheeb cais tsis ua tiav los ntawm hom kaw tshwj xeeb yog qhia. Thaum lub sijhawm kho dua tshiab, qhov ntsuas dej tsis sib txawv ntawm ntau hom kaw tau ntsuas: dome- hom kaw tau ua tiav 83% tus nqi dej tsis zoo, kab rov tav- hom kaw 75%, thiab lub thawv- hom kaw tsuas yog 45%. 45% tus nqi dej tsis zoo txhais tau tias ntau tshaj li ib nrab ntawm lub thawv- hom kaw hauv thaj teb tau tso cai rau cov dej nkag{10}} tus nqi tsis txaus siab rau cov khoom siv rau ntau xyoo lawm.
Txhua qhov splice point ntxiv kwv yees li $ 6 USD hauv kev ua haujlwm thiab kev poob qis. Ntxiv consumables (heat shrink, tiv thaiv lub tes tsho) thiab cov cuab yeej depreciation, thiab tus nqi ntawm ib tug rework sai sai tshaj tus nqi sib txawv ntawm ib tug pheej yig kaw thiab ib tug zoo.
Qhov no yog vim li cas xaiv qhov kaw nrog cov ntaub ntawv tsim nyog, cov txheej txheem sib khi, thiab kev npaj peev txheej tsis yog kev siv nyiaj - nws yog qhov kev txiav txim siab txog kev pheej hmoo.
Xaiv cov khoom siv: Thawj Kab Kev Tiv Thaiv
Kaw yog raug rau UV hluav taws xob, kub cycling, noo noo, mechanical stress, thiab qee zaum cuam tshuam rau lub cev. Qhov kaw uas tsis tuaj yeem tiv taus cov xwm txheej no yuav ua tsis tiav, thiab qhov tsis ua tiav yuav kim kho.
Siab -kawg kaw siv PC + ABS sib xyaw los yog txhawb nqa PP (PP + GF). Cov ntaub ntawv no ua tiav IK10 qhov cuam tshuam tsis zoo, tiv thaiv kev kaw ntawm cov ceg ntoo poob, dej khov, lossis kev puas tsuaj ntawm kev sib tsoo. UV tsis kam yog qhov tseem ceeb sib npaug: cov khoom tsis zoo- cov yas zoo ua nkig thiab tawg tom qab 2-3 xyoos raug tshav ntuj hauv huab cua xa tawm, cuam tshuam lub foob. High{10}}zoo UV{11}} tiv taus PC/ABS yas yog tsim tshwj xeeb rau kev ua haujlwm sab nraum zoov ntev. Cov ntaub ntawv zoo li PC, ABS, thiab PPR tuaj yeem tiv taus qhov hnyav xws li kev co, cuam tshuam, tensile cable distortion, thiab kub hloov pauv.

Cov ntaub ntawv vaj tsev siv nyob rau hauv siab - zoo kaw-PC, PP, los yog PP + GF- muab kev ruaj ntseg noo noo thaiv, thaum hlau cov khoom yog ua los ntawm stainless hlau los tiv thaiv corrosion.
Xaiv qhov kaw nrog cov ntaub ntawv zoo txhais tau hais tias xaiv ib qho uas tseem yuav zoo li qub thaum tus kws tshaj lij qhib nws tsib xyoos tom qab rau kev nthuav dav.
Sealing Mechanism: Qhov txawv ntawm kev tiv thaiv thiab kev puas tsuaj
Txoj kev sib khi yog ib qho tseem ceeb tshaj plaws uas txiav txim siab ntev - lub sij hawm cia siab. Cov kaw yog xa tawm sab nraum zoov, hauv av, hauv qhov tuav, lossis ntawm huab cua khiav, qhov chaw lawv ntsib los nag, plua plav, kub hloov pauv, thiab kev co.
Muaj peb yam tseem ceeb sealing technologies:
Thaum tshav kub kub -Shrink Sealingsiv ib lub raj tshwj xeeb coated uas shrinks nruj nreem nyob ib ncig ntawm lub cable nkag point thaum rhuab (feem ntau nrog ib lub teeb los yog kub phom), tsim kom muaj ib tug ruaj khov daim ntawv cog lus. Thaum rhuab, lub tes tsho cog lus nruj nreem nyob ib ncig ntawm lub cable nkag, tsim ib tug ruaj thiab nruj seal. Thaum tshav kub kub- ntsws tuaj yeem ua tiav IP67 lossis kev tiv thaiv siab dua thiab yog qhov zoo tshaj plaws rau "ib- lub sijhawm" kev teeb tsa xws li ncaj qha - faus lossis hauv av duct applications. Txawm li cas los xij, rov- nkag yuav tsum tau txiav lossis hloov cov khoom sib khi, uas tsis yooj yim rau kev saib xyuas.
Mechanical Sealing (Compression)siv cov roj hmab gaskets los yog O-rings compressed nyob ib ncig ntawm cable nkag chaw nres nkoj nrog threaded clamps, locking rings, los yog siab phaj. Mechanically kaw kaw tuaj yeem sib sau ua ke sai yam tsis muaj cua sov thiab txhawb nqa rov qhib thiab kaw. Qhov no ua rau lawv haum rau cov nyiaj siv ua haujlwm lossis cov ntsiab lus nkag tau yooj yim uas yuav tsum tau hloov tsis tu ncua.
Gel-Raws li Sealingsiv cov thermoplastic elastomer gel uas ua raws li ib txwm ua rau ntawm cov kab hluav taws xob thiab ua kom cov kab mob me me nyob ib ncig ntawm cov chaw nres nkoj nkag. Kev txhim kho yog ncaj nraim-cov cables raug nias rau hauv gel- cov chaw nres nkoj tsis muaj cua sov lossis zawm cov ntsia hlau. Qhov kaw tuaj yeem rov- nkag ntau zaus yam tsis muaj kev cuam tshuam rau lub foob. Gel seals feem ntau tau piav qhia tias yog "craft-insensitive"-lawv tsis cia siab rau tus neeg tsim kev txawj ntse rau kev sib khi kom zoo.
Qhov kev xaiv ntawm txoj kev sib khi yuav tsum nyob ntawm qhov nkag mus. Rau kev xa rov qab los yog lub cev lub cev uas rov- nkag tsis tshua muaj, cua sov- ntsws muab lub foob muaj zog tshaj plaws. Rau FTTH cabling cov khaubncaws sab nraud povtseg thiab poob cov khaubncaws sab nraud povtseg uas cov neeg siv tshiab nquag ntxiv, txhua yam los yog gel sealing muaj qhov tsim nyog yooj. Gel sealing enclosures yog dav suav hais tias yog qhov kev xaiv zoo tshaj plaws rau niaj hnub FTTH thiab sab nraum zoov tes hauj lwm vim kev hloov pauv thiab kev saib xyuas yooj yim.

Ib qho yuam kev feem ntau hauv kev xaiv kaw yog xaiv lub peev xwm raws li qhov xav tau tam sim ntawd. Network expansion yog inevitable. Thaum kaw tag nrho, qhov kev xaiv nkaus xwb yog ntxiv lwm qhov kaw - uas txhais tau hais tias txiav rau hauv cov kab uas twb muaj lawm, txhim kho lub kaw lus tshiab, thiab tsim cov ntsiab lus txuas ntxiv.
Ib qho uas tsis yog -scalable kaw yuam kev hloov pauv yav tom ntej thiab nce OPEX. Hloov pauv, kaw nrog cov tais splice txaus rau ob qho tib si tam sim no thiab yav tom ntej xav tau tso cai rau kev loj hlob ntawm cov organic yam tsis muaj kev hloov pauv loj.
Kev npaj peev xwm yuav tsum xav txog hom fiber ntau. Qee qhov kaw txhawb nqa ribbon fiber ntau tais, uas tuaj yeem ua rau kom ceev thiab txo qhov chaw lub cev xav tau rau siab - fiber ntau - suav splicing.
Qhov Re-Nrhiav Cov Lus Nug: Ua rau Kev Kho, Tsis yog Kev Txhim Kho xwb
Kev tu lub network tsis tas thaum lub kaw lus kaw. Splice kaw tau qhib rau ntau yam laj thawj -kev kuaj mob, kev nthuav dav, kev xa xov cable, thiab kev tshuaj xyuas niaj hnub. Kev kaw uas tsis tuaj yeem rov qab tau - nkag mus yam tsis tau rhuav tshem nws lub foob yuav dhau los ua kev lav phib xaub.
Telcordia GR-771 tsim cov kev cai dav dav rau fiber ntau optic splice kaw, suav nrog cov qauv tsim, kev siv tshuab thiab ib puag ncig, cov yam ntxwv xav tau, thiab kev sim ua haujlwm. Kaw tsim thiab sim ua raws li GR-771 cov kev cai yuav ua rau muaj kev ntseeg siab dua lawv lub neej ua haujlwm.
GR-771 qhia cov kev ntsuas nruj. Qhov kaw yuav tsum tau axially tig los ntawm 90℃thiab khaws cia rau tsib feeb, tom qab ntawd tig mus rau qhov qub thiab mus rau qhov sib txawv. After testing, the sample shall be checked for gas tightness-there shall not be any fall in air pressure beyond the prescribed limit, nor any physical damage to the cable or the closure. Cov dej nruj yog kuaj los ntawm kev tso dej hauv dej hauv qab 6.00-meter lub taub hau dej.
Tshaj li Telcordia, IEC 61300 tus qauv ntsuas kev sib dhos thiab kev tshem tawm ntawm kev kaw rau ntau lub sijhawm. Qhov kev sim no simulates tiag tiag - lub ntiaj teb teb tej yam kev mob uas kaw tau rov qhib dua thiab rov muab dua lawv lub neej ua haujlwm.
Re- nkag tau kaw-txawm yog tshuab lossis gel- kaw- txhawb nqa rov ua haujlwm yam tsis muaj kev cuam tshuam rau ib puag ncig. Qhov no yog qhov tseem ceeb tshwj xeeb rau kev kaw cov khoom siv hauv FTTH kev faib tawm, qhov twg cov neeg siv khoom ntxiv thiab hloov pauv ntau zaus.
Qhov kaw uas tuaj yeem qhib thiab rov muab dua 10 lossis 20 zaug hauv nws lub neej yog qhov kaw uas tsis tas yuav hloov pauv txhua zaus tus kws tshaj lij tuaj xyuas.
IP68: Lub hauv paus, tsis yog qab nthab
Kev tiv thaiv IP68 feem ntau raug kho raws li kev lag luam checkbox, tab sis qhov tseeb yog tias ntau qhov kev kaw lus thov IP68 tsis tas yuav ua tiav hauv thaj teb. Qhov tseeb IP68 kaw yuav tsum tiv thaiv kom tsis tu ncua immersion-tsawg kawg yog 1 meter qhov tob rau 24 teev-tsis muaj dej nkag.
Rau cov manholes, ncaj qha -fab fiber ntau, thiab dej nyab- thaj chaw, IP68 yog qhov yuav tsum tau ua. Tab sis txawm tias nyob rau hauv qhov chaw tsis tshua muaj huab cua, IP68 muab kev pov hwm tiv thaiv qhov tsis tau pom dua - cov ntaub ntawv nag los nag, lub qhov dej txhaws, lossis lub rooj dej hauv av uas nce siab tshaj qhov xav tau.
GLORY's inline splice kaw yog tsim los nrog siab - cov khoom siv polycarbonate zoo, uas muaj qhov cuam tshuam zoo heev, tiv thaiv UV, thiab tiv thaiv tshav kub, muaj peev xwm tiv taus qhov hnyav sab nraum zoov. Qhov ntsuas IP68 ua kom ntseeg tau tias cov kev kaw no tseem raug kaw txawm tias nyob hauv dej ntev ntev.
Tus nqi zais ntawm pheej yig kaw
Tus nqi sib txawv ntawm qhov qis - zoo kaw thiab siab - zoo kaw feem ntau me me. Tus nqi sib txawv ntawm kev kho qhov tsis raug kaw thiab tsis tas yuav kho nws yog qhov loj heev.
Cov peev txheej hauv kev lag luam qhia tias cov thawv fiber ntau yog li ntawm $ 45 txog $ 180 toj ib chav nyob ntawm qhov muaj peev xwm. Txawm tias nyob rau qhov kawg ntawm qhov ntau, tus nqi ntawm kev kaw qhov zoo yog ib feem me me ntawm tus nqi xa tawm - thiab ib feem me me tseem yog tus nqi ntawm ib qho kev ua tsis tiav.
Xav txog kev lag luam: 100-node FTTH project nrog 10% kev kaw ntxov ntxov yuav tsum tau rov mus xyuas 10 qhov chaw rau kev kho mob xwm txheej ceev. Txhua qhov kev kho yuav muaj kev ua haujlwm, mus ncig, khoom siv, thiab cov nqi pabcuam cuam tshuam. Cov kev txuag nyiaj los ntawm kev xaiv cov kaw uas pheej yig dua evaporate tom qab kev kho thawj zaug lossis thib ob. Qhov seem yim yog kev poob dawb huv.
Kev tsim kho tsis zoo lossis tsis raug kaw tuaj yeem ua rau muaj dej tsis zoo, fiber ntau micro-bending, mechanical stress on splices, thiab accelerate fiber aging. Kev sib khi tsis raug thaum lub sijhawm teeb tsa yog ib qho ntawm cov hauv paus feem ntau ua rau tsis ua haujlwm. Cov kws kho mob feem ntau ua tsis tau kom nruj sealing ceev kom zoo, tso cai rau ya raws corrode hlau qhov chaw thiab ua rau kom tsis muaj teeb liab.
73% ntawm kev sib txuas network yog los ntawm kev tiv thaiv kab mob.Ntau qhov teeb meem no tshwm sim ntawm qhov kaw - qhov chaw uas lub cable qhib, spliced, thiab rov ua dua. Xaiv qhov kaw uas txo qis kev teeb tsa kev ua yuam kev thiab ua kom muaj kev sib khi ncaj qha txo qis qhov ua tau ntawm kev koom nrog 73%.
Muab Tag Nrho Ua Ke: Ib Lub Cev Rau Kev Xaiv
Thaum ntsuas qhov sib txuas kaw, cov phiaj xwm network yuav tsum xav txog tsib yam tseem ceeb hauv kev ua ntu zus:
1.Daim ntawv thov ib puag ncig:Puas yog qhov kaw dav hlau, hauv av, lossis hauv qhov manhole? Dab tsi yog qhov kev cia siab ntawm qhov kub siab tshaj plaws, qib dej noo, thiab kev pheej hmoo ntawm lub cev?
2.Txoj kev sealing:Qhov kev kaw puas yuav tsum tau rov- nkag ntau zaus? Xaiv cov cua sov-shrink rau kev txhim kho mus tas li, siv tshuab lossis gel rau qhov chaw siv tau.
