Inter-kab qaum qaum khiav hauv pem teb tsa ceg yuav tsum xav ntau ntxiv. Ib qho chaw niaj hnub nrog cov hlua khi hlua khi tuaj yeem tso siab rau cov pob tw. Tab sis cov tsev qub uas muaj txoj hauv kev qhib hauv qab cov vuas luaj hauv pem teb qhia txog ib zaj dab neeg sib txawv - ko taw tsheb, dov lub laub, thiab qee zaus cov nas ua si tag nrho ua rau muaj kev cuam tshuam thiab puas tsuaj uas ob - kev tsim kho lub plhaub tsis tau tsim los daws. Yog tias koj tau sau tseg cov xwm txheej kab tsuag lossis koj txoj hauv kev tau koom nrog cov cuab yeej hnyav, qhov ntawd ib leeg ua rau muaj kev sib koom ua ke ntawm MPO armored ntawm cov pob txha caj qaum. Qhov kev txiav txim siab ntawm no yog qhov yooj yim: tshawb xyuas txoj hauv kev, ntsuas qhov tseeb ntawm kev hem thawj, thiab cia cov pov thawj lub cev coj koj.
Kev lag luam thiab ntug ib puag ncig tawm me me rau kev sib cav. Factory floors subject cables mus tas li vibration los ntawm machinery. Cov chav tswj mining qhia txog cov kab mob sib kis thiab qhov kub siab tshaj plaws. Sab nraum zoov 5G txee ncig los ntawm khov-thaw tej yam kev mob thiab raug UV. Cov tub rog ua tub rog ua ke ua ke tag nrho cov saum toj no nrog kev pheej hmoo cuam tshuam. Hauv cov kev teeb tsa no, tus qauv kab hluav taws xob tus qauv ntsuas kev ua haujlwm ntawm −20℃rau +60℃thiab nws kwv yees li 100–200 N crush resistance tsuas yog tsis txaus. Armored MPO patch cords, ntsuas los ntawm −40℃rau +75℃thiab muaj peev xwm tiv taus ntau dua 1,000 N ntawm lateral crush quab yuam, tsis yog qhov kev hloov kho hwm ntawm no - lawv yog qhov yuav tsum tau ua hauv paus. Yog tias koj qhov txuas khiav los ntawm txhua qhov chaw uas tsis muaj kev tiv thaiv ib puag ncig cov ntaub ntawv chaw, qhov kev xaiv armored tshem tawm hom tsis ua haujlwm uas tsis muaj nyiaj ntau ntawm kev ceev faj cable tuaj yeem tshem tawm tag nrho.
Tus ntoo khaub lig luv- txuas thaj ua rau thaj hauv ib lub txee - feem ntau nyob rau hauv ob metres ntawm cov kab ntawv, cov khoom siv hluav taws xob, thiab cov khoom siv transceivers - nyiam tus qauvMTP / MPO multimode thaj qaum. Ib puag ncig yog kaw tag nrho, lub cable tsis tshua muaj kev tswj xyuas tom qab kev teeb tsa thawj zaug, thiab kev hloov pauv yooj yim dua li kev sib tsoo. Armored stiffness tuaj yeem ua haujlwm tawm tsam koj hauv cov ntaub thaiv nruj uas khoov lub vojvoog ntawm tus nqi.
Dab tsi yog qhov tseeb hauv Txhua Cable
Tus qauv MPO lub cev cable feem ntau bundles 12 mus rau 144 fibers hauv nws ob lub tsho- txheej. CovMTP / MPO OM3 fiber ntau thaj qaumnyob rau hauv daim ntawv txheem ntsuas roughly 3.0 mm nyob rau hauv sab nraud txoj kab uas hla. Ob qhov kawg yog lub Hoobkas-tawm nrog qhov tseeb- polished MT ferrules - 8, 12, los yog 24 fibers rau ib qhov txuas - thiab txhua lub nkoj sib dhos nrog cov ntaub ntawv ntsuas tus kheej uas qhia qhov poob ntawm ib qho channel. Kev tsim kho yog txhob txwm tshaj tawm: tsuas yog muaj kev tiv thaiv txaus rau txoj hauv kev hauv tsev, uas ua rau qhov hnyav qis thiab ua rau kev tuav hauv cov tais ceev ceev yooj yim.
Armored MPO / MTP thaj cords qhia lub corrugated steel raj los yog interlocking txhuas armor ntawm lub fiber ntau thiab lub tsho sab nrauv. Qee cov qauv tsim txheej txheej aramid xov paj rau saum cov tswv cuab lub zog steel, thawb tsoo tsis kam mus rau kwv yees li kaum npaug ntawm cov qauv tsim. Qhov no ua rau cov kab sab nraud kom 4.0-5.0 mm thiab ntxiv qhov hnyav. Txawm li cas los xij, niaj hnub armored designs tseem ceeb xav tsis thoob. Ib qhov zoo-engineered armored MPO qaum tuaj yeem ua tiav qhov qis kawg ntawm lub vojvoog ntawm ib ncig ntawm 50 hli, uas tuaj yeem ua haujlwm tau nyob rau hauv feem ntau cov qauv cabling ib puag ncig. Qhov tseem ceeb ntawm kev tsim khoom sib txawv yog seb puas muaj cov txheej txheem tsis nyob nruab nrab ntawm cov cuab yeej cuab tam thiab fiber ntau ribbon - yam tsis muaj nws, cov armor nruj tuaj yeem nias tawm tsam fibers ntawm cov ntsiab lus khoov thiab qhia txog micro- khoov poob uas yuav tsis tshwm sim hauv qhov ncaj - cable insertion poob test.
Puas yog Armor Nqi Koj Teeb Meem?
Lub tsho armored nws tus kheej tsis ncaj qha nce qhov poob ntawm qhov txuas txuas. Insertion poob nyob ntawm ferrule geometry, fiber ntau alignment, thiab kawg -lub ntsej muag polish zoo - tsis nyob ntawm dab tsi qhwv ib ncig ntawm lub cev cable. Qhov qis- poob MTP connector ntawm ib qho armored los ua ke tseem hits 0.15–0.25 dB ib khub niam txiv thaum tsim kom raug, zoo ib yam rau tib lub connector ntawm lub cev txheem. Ntawm 400G SR4 wavelengths, ob hom cable siv cov qib sib npaug sib npaug xa cov kev ua haujlwm zoo ib yam poob - feem ntau 0.15–0.35 dB rau multimode OM4 cov rooj sib txoos.
Qhov twg armor tuaj yeem qhia txog kev nplua yog micro-bending. Yog hais tias lub raj steel tsis zoo los yog lub cable yog routed nrog khoov nruj dua li qhov tsawg kawg nkaus, cov armor compresses tawm tsam fiber ntau ribbon thiab micro- khoov attenuation creeps nyob rau hauv. Qhov no yog ib qho teeb meem ntawm kev tsim khoom thiab ib qho teeb meem kev qhuab qhia, tsis yog cov cuab yeej ntawm kev tsim armored. Thaum ntsuas armored MPO cords, nco ntsoov thov qhov khoov - cov ntaub ntawv ntsuas kev sib tw - tsis yog qhov kev nkag zoo li qub - daim ntawv pov thawj poob. Txhua tus neeg muag khoom uas tsuas yog muab ncaj nraim -cov lej poob cable yuav zais qhov teeb meem micro{10}} khoov. Rau kev nkag siab tob txog seb cov qib fiber ntau cuam tshuam li cas cov nyiaj txiag poob, lubOM1 txog OM5 multimode fiber sib pivmuab cov ntsiab lus tseem ceeb ntawm modal bandwidth thiab attenuation yam ntxwv ntawm cov chav kawm fiber ntau.
Qhov no kuj txhais tau tias rau ib ntu txuas qhov twg koj cov nyiaj siv kho qhov muag poob nruj - xws li ntev 400G SR4 ncav cuag thawb ze rau 100-meter OM4 txwv - koj yuav tsum muaj feem cuam tshuam rau qhov khoov-attenuation txaus ntshai ntawm armored cable yog tias txoj hauv kev muaj xws li nruj lem. Yog hais tias txoj kev ncaj thiab dav, armor yuav tsis raug nqi dab tsi rau koj optically. Yog hais tias txoj kev quab yuam lub cable los ntawm ob peb lub kaum ntse ntse, tus qauv cable qhov yooj yooj yim tuaj yeem ua rau qis dua tag nrho cov kev sib txuas poob hauv kev xyaum.
Mechanical Protection nyob rau hauv nthuav dav
Standard MPO trunk cables tswj cov kev ntxhov siab uas pom nyob rau hauv cov qauv cabling ib puag ncig: nruab nrab tensile loads thaum lub sij hawm installation rub, lateral siab los ntawm cable bundles nyob rau hauv sib koom tais, thiab qis - theem kev co los ntawm lub tsev systems. Qhov ob -cov qauv tsim, txhawb nqa nrog cov xov paj aramid, ua tau raws li cov kev cai ntawm IEC 60794 thiab TIA-568 rau sab hauv tsev cabling. Cov no tsis yog cov kab hluav taws xob tsis yooj yim - lawv tsuas yog tsim kho rau cov xwm txheej uas lawv yuav tau ntsib hauv qhov chaw tswj hwm zoo.
Armored cov rooj sib tham hais txog qhov kev hem thawj sib txawv. Cov hlau los yog txhuas txheej tiv thaiv crushing quab yuam uas yuav mus tas li deform tus qauv sheath. Cov rooj zaum dov ntawm ib puag ncig hauv pem teb, cov tsheb thauj khoom hnyav hauv lub tsev khaws khoom, cov hniav nas hauv qhov chaw uas tswj cov kab tsuag tsis zoo - cov no tsis yog qhov kev pheej hmoo siab; lawv yog cov ntaub ntawv tsis ua hauj lwm hom uas pab kho fiber ntau ntsib tsis tu ncua. Ib co armored MPO designs withstand tshaj 1,000 N ntawm lateral crush force, tsib mus rau kaum npaug ntawm lub peev xwm ntawm cov qauv tsim. Qhov ntev ntawm qhov kub thiab txias (−40℃rau +75℃piv rau −20℃rau +60℃rau cov khoom siv sab hauv tsev) ntxiv qhov sib txawv rau ob qho tib si rau kev xa tawm sab nraum huab cua-tswj chaw.
Thaum ntsuam xyuas seb ib ntu twg xav tau cov cuab yeej cuab tam, suav cov kev pheej hmoo ntawm lub cev raws li txoj hauv kev tiag tiag: kev cuam tshuam los yog cuam tshuam, cov ntaub ntawv nas lossis cov kab tsuag, qhov kub thiab txias excursions dhau qhov kev cai sab hauv, thiab seb cov routing rog khoov nruj dua 50 hli. Ob los yog ntau tshaj ntawm cov xwm txheej no ntawm ib txoj hauv kev ib ntu ua ib rooj plaub muaj zog rau kev tsim kho armored. Yog tias txoj hauv kev tau kaw tag nrho, huab cua- tswj tau, thiab tsis muaj kev phom sij ntawm cov khoom siv, tus qauv kab hluav taws xob yuav muab cov khoom siv kho qhov muag zoo ib yam nrog tsawg dua thiab tus nqi.
Polarity thiab Compatibility
Ob leeg armored thiab standard MPO sib dhos ua raws tib TIA-568 polarity txoj kev - Hom A (ncaj-los ntawm), Hom B (rov qab), thiab Hom C (pair-flip). Lub armor txheej tsis cuam tshuam rau tus pin kev sib raug zoo, kev teeb tsa poj niam txiv neej, lossis kev sib txuas sib txuas. Ib tug poj niam armored MPO-12 cord mates nrog ib tug txiv neej tus qauv MPO-12 adapter vaj huam sib luag tsis muaj teeb meem compatibility, thiab koj muaj peev xwm sib tov armored thiab standard segments nyob rau hauv tib qhov txuas ntev li ntev raws li fiber ntau suav, polarity hom, thiab connector qib match.
Ib qho kev xav tau tsim nyog yuav tsum tau sau tseg: vim tias cov hlua khi armored yog nruj dua, npaj cov kab txuas txuas kom zoo zoo hauv cov ntaub ntawv kaw ntom nti. Ntsiab - mus txog qhov tseem ceeb -down mating nyob rau hauv ib tug densely populatedMPO / MTP fiber ntau optic adapter vaj huam sib luagtej zaum yuav xav tau kev tshem tawm ntxiv thaum lub xov tooj ntawm cov cuab yeej tiv thaiv qhov kev khoov nruj uas cov hlua khi tau yooj yim.
