Kev Tswj Xyuas Zoo los ntawm Kev Npaj rau Kev Txais, Ib txhais tes- ntawm kev siv rau cov kws tshaj lij fiber ntau
Dab tsi yog Fiber Splice Enclosure tiag tiag
Fiber optic splicing tsis xaus thaum fusion splicer qhia txog kev nyeem ntawv tsis txaus. Lub splice tsuas yog ua tiav thaum qhov sib koom ua ke tau raug tiv thaiv kom zoo, kuaj, thiab teeb tsa hauv ib lub thawv fiber ntau. Kev nkag siab txog qhov sib txawv no yog dab tsi cais cov haujlwm niaj hnub ua los ntawm cov khoom siv txhim khu kev qha tiag tiag.
Lub splice enclosure ua plaub yam tseem ceeb: muab lub kaw lus, noo noo- pov thawj, plua plav- pov thawj, thiab kev vibration- tiv thaiv kev tiv thaiv rau cov fiber ntau cuam tshuam (cov ntaub thaiv sab nraum zoov feem ntau xav tau IP68 ntsuas ib IEC 60529); tswj slack fiber los tiv thaiv khoov-induced attenuation; cais cov ntsiab lus sab hauv splice los ntawm sab nraud cable nro thiab torsion los ntawm kev kho vajtse clamping; thiab tswj xyuas txoj hauv kev kom pom tseeb fiber ntau thiab daim ntawv lo kom cov neeg saib xyuas tuaj yeem nrhiav tus neeg fibers sai sai thaum lub kaw lus rov qhib.
Fiber optic splice enclosures tuaj nyob rau hauv ntau daim ntawv yam - dome, inline, phab ntsa-mount, thiab lwm yam - txhua tus haum rau txawv cable suav, routing yuav tsum, thiab installation ib puag ncig. Hom txoj cai yuav tsum raug xaiv thaum lub sij hawm tsim, tsis yog improvised ntawm -site.
Ua ntej -Kev Npaj Splicing
Tshawb xyuas Enclosure Compatibility
Ua ntej splicing fiber ntau cable, paub meej tias lub peev xwm enclosure (qhov ntau thiab tsawg ntawm 24 mus rau 144 fibers) phim qhov tseeb cable fiber ntau suav. Txheeb xyuas tus naj npawb ntawm fiber ntau splice tais, lawv cov txheej txheem stacking, thiab cov kab nkag thiab tawm qhov chaw nres nkoj. Yog hais tias lub cable muaj xws li hlau armor los yog lub hauv paus muaj zog cov tswv cuab, xyuas kom meej lub enclosure muaj cov sib thooj av thiab anchoring hardware - metallic cov ntsiab lus yuav tsum raug sib raug zoo nyob rau hauv ob qho tib si kawg, ib kauj ruam uas nquag overlooked. Tshawb nrhiav qhov muaj peev xwm tsis sib haum xeeb lossis kev tsis sib haum xeeb nruab nrab ntawm - txoj haujlwm raug nqi ntau tshaj li tsib feeb ua ntej - ua pov thawj ua haujlwm.
Cov cuab yeej thiab cov cuab yeej kuaj xyuas
Paub meej tias txhua yam khoom tam sim no thiab ua haujlwm: fiber ntau strippers, Ntau dua lossis sib npaug li 99% isopropyl cawv nrog lint-dawb kho qhov muag- qib so, precision fiber cleaver, fusion splicer, tshav kub-shrink splice protectors, lub qhov cub kub, thiab OTDR los yog optical zog ntsuas. Ua tib zoo saib xyuas seb cov hniav cleaver xav tau kev sib hloov los yog hloov, seb cov electrodes thiab V-grooves puas huv si, thiab seb lub qhov cub cua sov puas ua haujlwm ib txwm. Kev ntsuas ntsuas nrawm ua ntej txhua txoj haujlwm zoo tsim nyog rau lub sijhawm.
Slack Fiber Planning
Npaj rau 1 mus rau 1.5 meters ntawm slack fiber nyob rau hauv txhua sab nyob rau hauv lub enclosure, kho rau lub fiber splice tais qhov ntev thiab routing txoj kev. Tsawg slack quab yuam nruj khoov uas ua rau kom macro- khoov poob lossis kev pheej hmoo tawg; ntau dhau ua rau coiling nyuaj thiab neeg coob coob ntawm lub tais. Txiav txim siab ntawm qhov slack ntev thaum lub sij hawm npaj theem - tsis yog thaum koj twb sim coil fiber ntau rau hauv lub tais.
Yuav ua li cas rau Splice Fiber Optic Cable: Kauj Ruam los ntawm kauj ruam
Tshem lub Jacket thiab Txheej
Siv ib lub slitter kom tshem tawm lub tsho sab nrauv, tom qab ntawd txhuam cov txheej tsis rau hauv 125 μm liab qab iav nrog precision strippers. Txhawm rau xoob- cov kab hluav taws xob, cais cov raj tsis muaj kab los ntawm lub cev cable thiab tuav lawv ntawm qhov chaw nkag ntawm lub tais ua ntej stripping ib leeg fibers. Strip ntev feem ntau yog 30 mus rau 50 mm - sab laj phau ntawv splicer rau qhov yuav tsum tau muaj tseeb. Siv khov kho, txawm tias siab: dhau lub teeb tawm txheej txheej residue uas kis kab mob; hnyav dhau tuaj yeem tsim micro- tawg hauv iav. Khaws lub vojvoog khoov ntau dua 30 mm thoob plaws.
Ntxuav cov Bare Fiber
So cov stripped fiber ntau nrog lint -dawb optical so dampened nrog ntau dua los yog sib npaug rau 99% isopropyl cawv, stroking hauv ib qho kev taw qhia nkaus xwb. Siv lub ntsej muag tshiab txhua zaus. Peb lub ntsiab lus tseem ceeb ntawm no. Ua ntej, kev huv huv siv rau koj cov cuab yeej ib yam li - cleaver's V-groove thiab splicer's alignment stages sau microscopic particles from the stripping process and will re-pab fiber ntau yog tias sab laug qias neeg. Qhov thib ob, tsis txhob siv cov cua compressed; nws tuaj yeem nqa cov dej noo uas tsim cov kab mob tshiab. Thib peb, tsis txhob kov lub khob liab qab nrog koj cov ntiv tes tom qab ntxuav - cov roj ntawm daim tawv nqaij ua rau cov fiber ntau tsis muaj zog.
Txiav nrog Precision
Ua kom tiav lub ntsej muag tiaj tus, du, qhov kawg ntawm lub ntsej muag nyob rau hauv ib qho stroke siv lub siab -precision cleaver. Lub hom phiaj kawg- lub ntsej muag lub ntsej muag sib txawv ntawm 0.5℃lossis tsawg dua (tus qauv kev lag luam xav tau Tsawg dua lossis sib npaug li 1℃). Qhov liab qab fiber ntau txuas ntxiv dhau ntawm lub cleaver clamp yuav tsum phim lub splicer qhov yuav tsum tau cleave ntev - qhov no txawv ntawm cov chaw tsim tshuaj paus, yog li xyuas phau ntawv. Tshawb xyuas lub ntsej muag kawg nrog lub splicer ua -hauv lub koob yees duab lossis lub tshuab ntsuas fiber ntau. Yog tias koj pom daim tawv nqaij, daim di ncauj, lossis lub kaum ntse ntse, rov- txiav tam sim ntawd. Thaum lub sij hawm siab - ntim splicing ntawm fiber ntau cable, tig los yog hloov cov hniav ntawm ib ntus.
Teem thiab Fuse
Load ob qho tib si npaj fiber ntau xaus rau hauv splicer V-grooves. Lub tshuab cia li aligns, ua ntej -fuses, thiab ua kom tiav lub ntsiab arc fusion. Lub splicer qhia txog qhov kwv yees splice poob tam sim tom qab txheej txheem. Rau ib qho - hom fiber ntau, txhua qhov sib txuas yuav tsum ntsuas tsawg dua lossis sib npaug li 0.1 dB ib ITU-T G.652.D. Yog hais tias qhov kev nyeem ntawv siab tshaj 0.15 dB, re-cleave thiab re{12}}splice. Thaum poob tseem siab tom qab rov sim dua, tshawb xyuas qhov kawg- lub ntsej muag zoo, huv si, thiab electrode cov txheej txheem zoo dua li tsuas yog rov sim dua.
Thov Kev Tiv Thaiv Splice
Xaub lub pre-loaded heat-shrink splice protector tshaj qhov sib koom tes thiab muab tso rau hauv qhov cub kub. Tus tiv thaiv tiv thaiv qhov tsis yooj yim liab qab - iav splice point los ntawm cov neeg kho tshuab kev nyuaj siab, tiv thaiv stretch thiab khoov tsis ua hauj lwm. Xyuas kom tseeb tias lub tes tsho tau shrunk tag nrho tsis muaj cua npuas, lub pas nrig reinforcing yog nruab nrab, thiab ob qhov kawg yog kaw. Tsis txhob overheating, uas tuaj yeem deform lub tes tsho los yog ua rau cov fiber ntau hauv. Tom qab txias, xyuas seb puas muaj qhov offset lossis bulging. Siv lub tes tsho tiv thaiv zoo los ntawm cov chaw muag khoom muaj koob npe - qis- qib kev hloov pauv tuaj yeem qhia qhov ua tsis tiav ntau zaus ntau dua li tsib- xyoo ua haujlwm.
Txoj kev Fiber rau hauv Splice Trays
Muab txhua qhov kev tiv thaiv splice rau hauv nws qhov tshwj xeeb ntawm lub phaj fiber ntau, ces coil lub slack fiber nyob rau hauv lub tais txoj kab. Khaws lub vojvoog khoov ntawm ntau dua lossis sib npaug li 30 mm txhua lub sijhawm thiab tsis txhob hla cov fibers. Cov txheej txheem kub rau kev ua haujlwm fiber ntau: txhua txoj hlua tuaj yeem taug qab tus kheej thiab ua haujlwm ntawm tus kheej yam tsis muaj kev cuam tshuam rau nws cov neeg nyob ze. Thaum stacking ntau lub tais, xyuas kom lub tais sab sauv tsis txhob nias rau ntawm cov fibers hauv qab no, thiab lub tais npog tsis txhob rub cov hlua. Pinch-induced micro- breaks yog notoriously nyuaj rau nrhiav tau nrog ib tug OTDR vim hais tias lawv tshwm sim heev ze rau lub splice point uas lawv tshwm sim raws li ib tug tshwm sim. Lub qhov muag pom kev txhaum qhov chaw (VFL) zoo dua rau kev ntes cov no.
Kuaj Ua Ntej Kaw
Txoj cai cardinal: tsis txhob kaw lub qhov rooj nrog cov teeb meem tsis daws teeb meem. Tshawb xyuas txhua qhov splice ua ntej sealing. Kev rov ua dua tshiab hauv lub xeev qhib yog qhov pheej yig dua thiab sai dua li rov qhib lub kaw lus fiber ntau kaw - thiab txhua qhov rov qhib dua yuav ua rau muaj kev pheej hmoo ntawm kev tawg ua tiav fiber ntau.
