Patchcord Ntau Lawm Kab: Cov Neeg Yuav Khoom Qhia
Ib 1-meter SC simplex jumper mus rau $ 2 los ntawm qee tus neeg xa khoom, $ 12 los ntawm lwm tus. Tib hom connector, tib cable spec ntawm daim ntawv. Qhov txawv li cas? Txhua yam uas tsis tshwm sim ntawm daim ntawv spec.
Tus nqi sib txawv ntawd rov qab mus rau kev txiav txim siab ntau lawm- qib fiber ntau, aramid zoo, ferrule nrhiav, polishing khoom, kuaj raws tu qauv. Yog tias koj tab tom ntsuas cov neeg xa khoom lossis xav txog kev teeb tsa koj tus kheej, nkag siab txog cov nqi tsav tsheb no tseem ceeb. Tsis yog vim pheej yig dua ib txwm phem dua (qee zaum nws tsuas yog siv tau ntau dua), tab sis vim tias koj yuav tsum paub qhov koj tab tom yuav tiag tiag.
Vim li cas tus nqi sib txawv heev
Cov ntaub ntawv nyoos suav txog 45-55% ntawm tus nqi tsim khoom. Qhov ntawd yog qhov uas feem ntau cov nqi txiav nyiaj tshwm sim, thiab nws feem ntau pom tsis tau rau cov neeg yuav khoom.
Fiber core qibyog tus loj. A- qib cores los ntawm cov neeg tsim khoom loj piv rau C lossis D- qib uas qee lub chaw tsim khoom hloov pauv. Yog tsis muaj interferometer los xyuas-thiab ntau cov haujlwm me me tsis muaj ib qho -koj tuaj yeem tsis qhia txog kev teeb tsa. Tom qab ntawd koj tau txais kev poob ntau dhau, kev sib kis luv luv ncav cuag, qhov tsis sib xws ntawm cov tub ntxhais txoj kab uas hla uas ua rau splicing npau suav phem. Kuv tau pom OM3-300 sau tias yog OM4. tshwm sim ntau dua li kev lag luam nyiam lees paub.
Aramid fiber ntau(Kevlar tsuas yog DuPont lub npe rau nws) yuav tsum tau tiv thaiv cov fiber ntau los ntawm tensile stress thaum rub. Tiag aramid nqi nyiaj. Polyester xov paj tus nqi tej zaum ib -feem kaum ntau npaum li cas thiab yuav luag tsis muaj dab tsi. Qee tus neeg muag khoom siv nws li cas. Txoj kev nrawm los kuaj xyuas: ntaus cov kab tawm nrog lub teeb. Polyester melts thiab hlawv, aramid tsis. Peb twb muaj cov cables los thov aramid uas ua tsis tau qhov kev sim.
Ferrule zoocuam tshuam rau kev kho qhov muag ncaj qha. Zoo ferrules spec 1.0μm concentricity. Cov pheej yig khiav 1.5μm thiab tom qab ntawd tau txais "kho" thaum kuaj- tig mus txog thaum lawv tshwm sim los ntawm kev siv. Dhau qhov ntsuas, ua tsis tiav nyob rau hauv lub tshav pob thaum mated randomly. Qee qhov chaw txawm siv cov ferrules uas twb tau dhau los ntawm ib lub voj voog polish. Qhov ntev protrusion tsis ncaj ncees lawm, qhov poob qis nce mus, thiab koj tab tom nrhiav seb vim li cas koj lub network muaj teeb meem rau lub hlis tom qab.
Cov lus nug ntawm cov khoom siv yog tsawg dua txog tus nqi thiab ntau ntxiv txog kev ua raws cai. LSZH raug nqi ntau dua li PVC tab sis cov cai hauv tsev yuav tsum tau siv rau sab hauv tsev. Qee cov neeg muag khoom hais txog LSZH thiab nkoj PVC. Koj tsis tuaj yeem qhia los ntawm kev saib.
Production Line Economics
Qhov kev txiav txim siab automation tsis nyuaj thaum koj paub koj tus lej. Hauv qab li ntawm 20,000 connectors ib hlis, semi- tsis siv neeg polishing nrog phau ntawv sib dhos feem ntau ua rau muaj kev nkag siab ntau dua li kev ua haujlwm puv. Tshaj 100,000 txhua hli, tag nrho automation them rau nws tus kheej. Nyob rau hauv nruab nrab, nws nyob ntawm koj cov nqi zog thiab ruaj khov koj cov khoom sib xyaw.
Komax tau tshaj tawm cov lus qhia tias automation dhau los ua kev lag luam ncaj ncees saum 250,000 cable xaus txhua xyoo (komax.com). Qhov ntawd taug nrog qhov peb tau pom. Cov khoom siv tus nqi dhia los ntawm ib nrab - pib mus rau tag nrho automation yog qhov tseem ceeb -feem ntau $ 300K lossis ntau dua- thiab nws tsuas yog ua rau kev nkag siab ntawm ntim.
Nov yog lej lej uas tseem ceeb rau kev txiav txim siab automation:
| Teeb tsa | Rau -Cov nqi sib txuas | Lub hli tawg-Txawm li cas los xij |
|---|---|---|
| Tes polishing | $0.50 lab + $0.02 consumables=$0.52 | - |
| Semi-auto (xws li $150K peev) | $0.08 lab + $0.11 khoom + $0.02 consumables=$0.21 | ~ 8,000 units |
| Tag nrho automation (xws li $ 500K peev) | $0.02 lab + $0.15 khoom + $0.02 consumables=$0.19 | ~ 25,000 units |
Qhov ntawd yog $0.31 ib - connector sib txawv ntawm tes polishing thiab semi- nws pib ntxiv ceev. Ntawm 50,000 ib hlis ntim, nws yog $ 15,500 / hli hauv kev txuag nyiaj. Cov khoom siv them nws tus kheej tawm hauv qis dua ib xyoos. Tab sis ntawm 5,000 txhua hli ntim, koj txuag tau $ 1,550 / hli tiv thaiv $ 150K outlay. Qhov ntawd yog yim - xyoo them rov qab. Tsis tsim nyog.
Tus nqi ua haujlwm hloov qhov kev suav no ntau heev. Cov lej saum toj no suav tias yog $ 15 / teev. Ntawm $8/teev, phau ntawv yuav siv tau ntev dua. Ntawm $ 25 / teev, txawm tias cov ntim nruab nrab pom zoo automation.
Cov txheej txheem cov ntsiab lus uas qhov tseem ceeb
Kuv yuav tsis taug kev los ntawm tag nrho kaum ob qhov kev tsim khoom. Feem ntau ntawm lawv yog qhov ncaj ncees yog tias koj muaj cov cuab yeej tsim nyog thiab cov neeg ua haujlwm tau txais kev cob qhia. Tab sis peb cheeb tsam ua rau feem ntau ntawm cov teeb meem zoo.
Epoxy khoyog qhov twg ntau cov connectors tau puas tsuaj ua ntej lawv txawm mus txog polishing. EPO-TEK 353ND sib xyaw 10: 1, kho ntawm 150℃li ib feeb. Koj tuaj yeem qhia tau tias nws ua tiav thaum cov xim hloov ntawm yellowish -ntsuab rau amber. Undercure ua rau rub tawm tsis ua haujlwm. Overcure ua rau nws nkig. Multimode tshwj xeeb yog touchy-thermal shocks tawg lub hauv paus. Qee cov kauj ruam ua haujlwm- kho (pib ntawm 80 degree, nce siab) txhawm rau tiv thaiv qhov no, tab sis qhov ntawd yuav tsum muaj qhov programmable qhov cub. Cov kab nyiaj hla hla nws thiab lees txais cov txiaj ntsig ntaus.
Qhov kawg polish kauj ruamtau hla ntau tshaj qhov yuav tsum tau ua. Pob zeb diamond polishing tsim kom muaj cua sov txaus los hloov cov refractive index ntawm sab saum toj 20-30μm ntawm lub ntsej muag fiber ntau. CMP slurry tshem tawm cov txheej uas puas lawm. Hla nws thiab koj yuav dhau qhov kev tshuaj xyuas qhov muag- lub ntsej muag kawg zoo nkaus li zoo -tab sis qhov kev ntsuam xyuas IL random-mating qhia qhov poob siab. Tsis yog txhua tus connector, tsuas yog txaus los tsim teeb meem teb.
Tsis tas li: tsis txhob ntxuav nrog cawv tom qab CMP. Ua rau pom kev mus tas li. Coj peb 200 qhov txuas txuas los txiav txim qhov ntawd.
Rubber ncoo durometeryog boring tab sis tseem ceeb. Pads yog spec'd ntawm Shore 50-65. Lawv harden nrog siv. Ntawm ntug dej hiav txwv 70+ koj tau txais geometry variation- vojvoog ntawm curvature thiab fiber ntau qhov siab pib drifting. Cov tshev txhua hli ntes nws. Feem ntau cov nqi tsom mus ua haujlwm xyuas peb lub hlis twg yog tias txhua, thiab xav paub yog vim li cas lawv cov txiaj ntsig tau hloov pauv.
Cov Specs Zoo thiab lawv txhais li cas rau kev nkag mus rau kev lag luam
IEC 61753-1 Qib B (txhais tau tias IL Tsawg dua lossis sib npaug rau 0.12dB, max Tsawg dua lossis sib npaug li 0.25dB) tau dhau los ua qhov tsawg kawg nkaus rau kev sib tham hauv xov tooj thiab chaw ua haujlwm. Qib C (txhais tau tias tsawg dua lossis sib npaug ntawm 0.25dB) zoo rau kev lag luam thiab tsev kawm ntawv. Qib D yog tsev nyob.
Yog tias koj qhov kev tsim khoom tsis tuaj yeem ntaus Qib B tsis tu ncua, koj raug kaw tawm ntawm cov ntawv cog lus uas tau them nyiaj zoo. Cov khoom siv thiab cov txheej txheem tswj kom mus los ntawm Qib C mus rau Qib B muaj peev xwm tus nqi tej zaum 40-60% ntau dua. Tsis yog qhov sib txawv tsis tseem ceeb, tab sis kev lag luam nkag mus sib txawv yog qhov loj dua.
Lub geometry specs nyob rau hauv GR-326 (lub vojvoog ntawm curvature, fiber ntau siab, apex offset) tseem ceeb vim hais tias lawv kwv yees random-mating kev ua tau zoo. Ib qho kev sib txuas uas zoo nkaus li zoo rau tus neeg muag khoom tus tswv jumper yuav ntsuas 0.35dB tiv thaiv koj cov nroj tsuag uas tau teeb tsa vim tias cov duab geometry yog marginal. Qhov no yog vim li cas 3D interferometry cov ntaub ntawv tseem ceeb thiab vim li cas qee tus neeg muag khoom tsis xav muab nws.
Ib yam uas 2022 IEC hloov kho: kev ua haujlwm kho qhov muag tam sim no ua qhov tseem ceeb tshaj qhov kev tshuaj xyuas pom. Ib qho txuas nrog me me khawb hauv Zone B tuaj yeem xa khoom yog IL / RL ua tau raws li qhov tshwj xeeb. Tsim nyog paub thaum koj tab tom ntsuas tus neeg xa khoom tsis lees txais tus nqi thov.
Kev soj ntsuam cov neeg muab khoom
Nug txog cov ntaub ntawv. Fiber qib, aramid qhov chaw, ferrule tsum. Cov lus teb tsis meej lossis kev ntxhov siab ntawm cov lus nug yog cov ntaub ntawv.
Nug txog kev xeem . 100% lossis qauv? Master jumper nkaus xwb los yog random mating? Lawv puas muaj 3D interferometry thiab lawv puas yuav qhia cov ntaub ntawv?
Nug txog kev tawm los. Kev thov peev tsis txhais tau ntau. Ib txoj kab ua 10,000/hnub ntawm 8% tsis lees paub muab cov khoom siv tsawg dua li ib qho ua 6,000/hnub ntawm 2%. Thiab cov kev tsis lees paub mus rau qhov chaw-qee zaum rau cov neeg siv khoom xav tau tsawg dua, qee zaum relabeled li lub tsev hom rau lwm lub lag luam.
Nug txog cov khoom siv vintage. Qhov no tau raug saib tsis taus . 2015- era polishing tshuab ntawm thawj firmware tsis tsim cov txiaj ntsig zoo ib yam li cov cuab yeej siv tam sim no nrog kev tswj hwm kev hloov siab. Qhov sib txawv pom nyob rau hauv geometry sib xws.
Yog tias lawv tsis cia koj mus xyuas lub chaw, qhov ntawd kuj yog cov ntaub ntawv.
Daim duab Demand
Qhov no tseem ceeb rau kev txiav txim siab lub sijhawm. Corning tau tshaj tawm rau pej xeem tias AI cov chaw zov me nyuam xav tau kwv yees li 10x fiber ntau ntawm cov khoom tsim (corning.com). US FTTH xa tawm tau ntaus cov ntaub ntawv xyoo tas los-10.3 lab lub tsev dhau mus, ua rau tag nrho cov kev pab them nqi rau 88 lab tsev neeg. Qhov kev pab cuam BEAD yog $42 nphom yuav tsum muaj fiber ntau- ua ntej. MPO / MTP ntu tau loj hlob ntawm tus lej ob.
Cov khoom siv lead ua lub sij hawm normalized tom qab 2022-2023 mess. Cov khoom txheem yog 6-8 lub lis piam tam sim no. MPO fixtures tseem khiav 10-14 lub lis piam. Yog tias koj muaj peev xwm ntxiv, pib qhov kev yuav khoom thaum ntxov.
Kab hauv qab
Tus $2 jumper thiab $12 jumper zoo ib yam. Qhov sib txawv yog nyob rau hauv cov ntaub ntawv qib, kev tswj cov txheej txheem, thiab kev xeem nruj- tsis muaj leej twg tshwm sim ntawm daim ntawv teev cov ntaub ntawv. Kev nkag siab qhov twg cov nqi tsim khoom tau los ntawm kev cia koj ntsuas cov neeg muag khoom ntawm qhov tseem ceeb es tsis txhob sib piv cov nqi hais.
Txawm hais tias koj tab tom nrhiav lossis tsim, cov lus nug zoo ib yam: qib fiber ntau, dab tsi aramid, dab tsi ferrule concentricity, qhov kev xeem raws tu qauv, dab tsi tawm los. Cov neeg muab khoom uas teb kom meej yog qhia koj ib yam dab tsi. Cov neeg muab khoom uas tsis yog kuj qhia koj ib yam dab tsi.
Nyob rau niaj hnub no txoj kev loj hlob ntawm cov ntaub ntawv ceev ceev, txawm hais tias nws yog loj heev kis tau tus mob nyob rau hauv cov ntaub ntawv chaw zov me nyuam los yog network nkag mus rau hauv countless tsev neeg, txhua yam nyob ntawm ib tug seemingly inconspicuous tab sis tseem ceeb heev tivthaiv -thepatch cord (jumper hlau). Raws li lub hauv paus tseem ceeb rau kev tsim cov khoom tseem ceeb no, cov kab hluav taws xob ntau lawm yog lub luag haujlwm tseem ceeb ntawm kev tsim kev sib txuas lus. Kab lus no yuav pib los ntawm cov ntsiab lus tseem ceeb ntawm thaj cords thiab muab ib qho hauv - kev tsom xam qhov tob ntawm daim duab tiav ntawm cov kab hluav taws xob ntau lawm, nthuav qhia cov neeg nyeem nrog cov kev paub dav dav.
