Ntau tus neeg yuav khoom (thiab txawm tias qee pawg tsim khoom) tseem xaiv MPO cov txheej txheem sib dhos raws li cov ntaub ntawv tsis tiav. Qhov teeb meem yog, tus nqi tsis tshwm sim tam sim ntawd - nws tshwm tom qab lirov ua dua, tsis ruaj tsis khov IL, polarity surprises, thiab "vim li cas qhov no batch dheev zuj zus?" lub sijhawm. Thiab los ntawm lub sijhawm cov teeb meem no ntog, cov paj tau ploj mus lawm.
Peb pom tus qauv zoo sib xws thaum cov neeg siv khoom ncav cuag HengTong:
"Tsis muaj dab tsi hloov, tab sis hnub no lub qhov rais ferrule kua nplaum ua kom shrinking / fibers raug nthuav tawm / polarity yog tawm / poob yog drifting."
Feem ntau, lub hauv paus ua rau tsis yog qhov tsis meej. Feem ntau nws yogkev taw qhia + kua nplaum tswj + kho kev qhuab qhia- cov kauj ruam me me, tab sis lawv txiav txim siab seb lub connector nyob ruaj khov tom qab thermal cycling thiab tuav.
Yog li es tsis txhob sau ib "zoo meej-saib" SOP, Kuv yuav taug kev koj los ntawm cov txheej txheem uas peb piav qhia hauv pem teb hauv khw: yuav ua li cas, nrhiav dab tsi, thiab dab tsi nyiam ua ntej.
Qhov txheej txheem no tau npog dab tsi thiab vim li cas nws tseem ceeb
Peb tab tom tham txog ib qho tshwj xeeb tab sis tseem ceeb txuas hauv MPO ntau lawm:
- Fiber nkag rau hauv MPO ferrule
- Epoxy filling tswj
- Ob -theem qhov cub curing
- Cov kua nplaum ntxiv thaum kho
- Tshaj tawm - kho kom txias ua ntej ua haujlwm tom ntej
Vim li cas qhov txuas no yog qhov yooj yim heev: yog tias cov fiber ntau ua tsis raug lossis lub xeev epoxy tsis ruaj khov, koj yuav tsis pom tam sim ntawd. Cov teeb meem tuaj yeem tshwm sim tom qab xws li:
- polarity mismatch (qhov phem tshaj - rooj plaub: rework los yog seem)
- tsis ruaj tsis khov kev poob
- epoxy contamination nkag mus rau hauv optical txoj kev / endface
- fiber fixation tsis muaj zog tom qab thermal cycling
Ua ntej koj pib: qhov chaw, cov cuab yeej, thiab ib qho "tsis yog{0}}negotiable" kev taw qhia ua haujlwm
,
Cia peb khaws cov kev npaj yooj yim- feem ntau qhov ua tsis tiav tsis yog los ntawm cov khoom ploj, tab sis hla ib daim tshev.
Yam koj yuav xav tau
- MPO ferrule nrog qhov rais
- Kho lub caij nplooj ntoos hlav matched rau tus qauv ferrule
- Pom zoo epoxy rau MPO ferrule bonding
- Ntxuav cov ntaub so / lint-dawb ntaub so ntswg
Khoom siv
- Epoxy dispensing tool
- Curing qhov cub nrog qhov kub thiab txias / sijhawm tswj
- Clean workstation (plua plav yog yeeb ncuab tiag tiag ntawm no)
Qhov tsis yog -negotiable orientation
Ferrule qhov rais tig musyog koj lub luag haujlwm ua haujlwm.
Thaum twg peb hais"blue fiber tig rau txoj cai", peb txhais tau tias:
nrog rau lub qhov rais tig mus, thawj fiber nyob rau sab xis ntawm lub qhov rais yog xiav (los yog txiv kab ntxwv, nyob ntawm txoj kev).
Qhov no ib qho kev siv txuag ntau qhov tsis meej pem tom qab.
Cov kauj ruam nkag mus: peb ua dab tsi ua ntej thiab cov neeg feem ntau tsis nco qab?
Kauj ruam A - Caij nplooj ntoos hlav installation (yog, nws yog me me, tab sis tom qab ntawd nws tom)
Koj ntxig lub caij nplooj ntoos hlav rau hauv txoj hauj lwm hauv lub ferrule, ces paub meej tias nws zaum zoo (tsis tilted, tsis ploj).
Yog vim li cas peb xaiv ntawm no yog cov tswv yim: ib qho ploj/mis-ntsia lub caij nplooj ntoos hlav tuaj yeem ua rautsis ruaj tsis khov ferrule zaumthiabinconsistent mating kev sib cuag, uas tshwm sim raws li kev coj cwj pwm tsis sib haum xeeb.
HengTong pab neeg ceeb toom (Peb pab pawg engineering cov lus qhia): Caij nplooj ntoos hlav zaum sai
Ntawm kab peb siv 3-kauj ruam kos:
- Saib:caij nplooj ntoos hlav yog tag nrho nyob rau hauv lub hnab tshos, nruab nrab, tsis caij ntawm ntug los yog qaij.
- Xovxwm:maj mam nias ib zaug -yuav tsum compress smoothly thiabrov ncaj(tsis muaj nplaum / sab plhu).
- Tus txiav txim:yog tias nws tsis "nias ncaj nraim, rov qab ncaj," re- zaum tam sim ntawd.
Kev teeb tsa tsis raug (zoo yees duab refs):tsis muaj caij nplooj ntoos hlav, qaij lub caij nplooj ntoos hlav, ib nrab- zaum ntawm lub hnab nqa khoom ntug, tsis ncaj ncees lawm lub caij nplooj ntoos hlav qauv (ntev / nruj mismatch).
Kauj Ruam B - Epoxy daim ntawv thov + fiber ntau ntxig (qhov no yog qhov "polarity" ua tiag)
Siv epoxy tusyees kom lub ferrule absorbs kua nplaum uniformly. Tom qab ntawd ntxig cov fiber ntau ribbon / fiber cores kom zoo zoo.
Tam sim no qhov tseem ceeb:Txoj kev A/B/C tsis yog "txoj cai ntawv" - nws ncaj qha hloov li cas koj ntxig fibers ntawm Xaus A thiab kawg B.
Txoj Kev A (tib yam kev taw qhia ntawm ob qho kawg)
- Xaus A:xiav yog thawj fiber nyob rau sab xis ntawm lub qhov rais
- Xaus B:xiav yog thawj fiber nyob rau sab xis ntawm lub qhov rais
Txoj Kev B (tib yam kev taw qhia ntawm ob lub cim kawg)
- End A (tus cim kawg):xiav yog thawj fiber nyob rau sab xis
- End B (tus cim kawg):xiav yog thawj fiber nyob rau sab xis
Txoj Kev C (ib kawg hloov pauv + nruj ntu ntu)
- End A (tus cim kawg):xiav yog thawj fiber nyob rau sab xis
- End B (tus cim kawg):txhua ob xim hla, thiabtxiv kab ntxwv yog thawj fiber nyob rau sab xis
Nov yog qhov peb rov ua dua hauv kev tsim khoom (vim tias nws tiv thaiv qhov yuam kev kim tshaj plaws):
Polarity yuam kev yuav zoo li "zoo" tom qab tso, thiab tsuas yog pom tseeb tom qab kho / kuaj.
Yog li ntawd peb kho polarity pov thawj raws li qhov yuav tsum tau kuaj xyuas ua ntej lub qhov cub.
Cov ntaub ntawv Source:HengTong sab hauv SOP / ntau lawm -validated insertion reference.
| Txoj kev Polarity | Xaus A (qhov rais nce) sab xis- sab 1st fiber | Xaus B (qhov rais nce) sab xis- sab 1st fiber | Txoj cai tshwj xeeb |
|---|---|---|---|
| Txoj Kev A | Xiav | Xiav | Tib siv ob qhov kawg |
| Txoj kev B | Blue (lub cim kawg) | Blue (lub cim kawg) | Paub meej tias "tus cwj pwm kawg" txhais |
| Txoj kev C | Blue (lub cim kawg) | Txiv kab ntxwv (lub cim kawg) | Hla kev npaj txhua ob xim |
Table 1 - Polarity insertion ceev siv
Kev txhais lus (vim li cas lub rooj no tseem ceeb):
Yog tias koj tsis tuaj yeem teb "qhov xim twg yog thawj fiber ntau ntawm sab xis ntawm lub qhov rais?" nyob rau hauv ib tug thib ob, txoj kab muaj kev pheej hmoo. Cov lus no yog txoj hauv kev ceev tshaj plaws los nres qhov yuam kev ua ntej kho.
Kho: ob- theem profile, thiab vim li cas peb tsis kho nws li "set-thiab-tsis nco qab"
Tom qab ua tiav, koj muab cov khoom tso rau hauv qhov cub kho qhov cub thiab khiav ob -theem profile.
Table 2 - Ob-theem qhov cub curing profile
Cov ntaub ntawv Source:HengTong sab hauv kho tus qauv rau cov txheej txheem no (khw-cov nqi ua haujlwm hauv pem teb).
| Theem | Kub | Sijhawm | Qhov theem no yog rau dab tsi |
|---|---|---|---|
| Theem 1 | 60 ± 5 degree | 10–20 feeb | pib teeb tsa + tswj kev khiav |
| Theem 2 | 80 ± 5 degree | 30–40 feeb | kho tag nrho + ntev - lub sij hawm txhua yam stability |
Kev txhais lus (dab tsi tib neeg nco):
Theem 1 yog qhov uas koj yuav pom ntau zausqhov rais kua nplaum theem poobyog tias tsis ua tiav.
Theem 2 xauv lub zog- yog lub qhov cub drifts los yog lub sij hawm tawm, koj yuav pom tom qab tsis ua hauj lwm xws li loosening los yog drift.
HengTong pab neeg ceeb toom: Cub pov thawj + cov tsos mob drift
Kev lees paub niaj hnub:Peb ua antsuas kub txhua hlisiv ib tug ywj siab sojntsuam/thermometer muab tso rau ntawm lubcov khoom siv tiag tiag(tsis yog nyeem qhov cub zaub xwb). Cov ntaub ntawv theem 1 thiab theem 2 ruaj khov.
Ceev txhua hnub kuaj:Ua ntej thauj khoom, cia lub qhov cub kom ruaj khov, tom qab ntawd paub meej tias cov zaub nyob ruaj khov thiab lub sijhawm ua haujlwm ib txwm ua.
Cov tsos mob tshwm sim ntawm cov khoom:qhov rais kua nplaumshrinks sai dua li ib txwm nyob rau theem 1, ntau zausfiber ntau raug, los yog kho qhov chaw xav taume ntsis "mos" / tsis muaj zogthiab qhia tias muaj kev pheej hmoo siab dua ntawm kev xoob tom qab tuav.
Cov kauj ruam uas txuag tau ntau ntawm rework: kua nplaum ntxiv thaum kho
Qhov no yog feem ntau pawg hauv qab - kwv yees.
Thaum 10 feeb tom qab kho pib:
ntxiv epoxy nyob rau hauv lub qhov rais ferrule
tswj tus nqi kom nws tsis ntws tawm
yog tias muaj dej dhau lawm, so tam sim ntawd
Ces,txhua 5 feeb tom qab rov ua dua:
kos qhov rais kua nplaum theem
yog tias cov kua nplaum tsis txaus thiab fiber ntau pib nthuav tawm → ntxiv rau lub sijhawm
Vim li cas peb thiaj hais rau qhov "10 min + txhua 5 min" atherosclerosis?
Vim tsis muaj nws, dab tsi feem ntau tshwm sim yog:
kua nplaum shrinks / ntws thaum ntxov curing
qhov rais theem poob
fiber ntau ua pom
Tom qab kho tag nrho, koj nyob nraum daig nrog ib tug hardened defect uas yog kim kom rov zoo
Daim duab 1 - Daim ntawv teev npe ncua sij hawm
Txhais lus:
Muab lub sij hawm no tso rau ntawm qhov cub. Cov neeg tsis hnov qab vim lawv tsis saib xyuas -cov neeg tsis nco qab vim lawv tsis khoom. Qhov pom kev sib dhos ua rau cov txheej txheem ruaj khov.
Txias: txoj cai yooj yim, tab sis nws tiv thaiv "tsis pom kev puas tsuaj"
Tom qab curing:
tshem tawm cov khoom los ntawm qhov cub
muab tso rau hauv qhov chaw huv, qhuav
static cua txias Ntau dua los yog sib npaug rau 10 feeb
tsuas yog hloov mus rau kauj ruam tom ntej tom qab ncav cuag chav sov
Peb hais qhov no bluntly nyob rau hauv pem teb:
Tsis txhob maj qhov kub rau hauv kev ua haujlwm tom ntej.
Cov cua sov uas seem tuaj yeem ua rau deformation lossis tuaj yeem hloov pauv cov txheej txheem tom ntej no li cas (tshwj xeeb tshaj yog tias cov kauj ruam tom ntej no suav nrog kev tuav / kho).
Dab tsi "zoo epoxy" zoo li nrog cov lej + daim duab tso rau?
Koj tsis xav tau cov lus zoo ntawm no -koj xav tau lub hom phiaj pom tseeb thiab txoj cai hla / tsis ua haujlwm.
Cov ntaub ntawv Source:HengTong sab hauv pom tus qauv rau epoxy tswj hauv kev ua haujlwm no.
| Thaj tsam | Lub hom phiaj zoo li | Tus lej phiaj | Ua tsis taus pa yog tias tawm ntawm spec |
|---|---|---|---|
| Butt sib koom nto | Crescent puab | 1.0-1.5 hli qhov siab | ntau dhau → kho qhov muag kab mob; tsawg dhau → qaug zog fixation |
| Ferrule qhov rais | Concave, tsis muaj fiber ntau raug | fiber ntau tsis raug | raug → tsis zoo fixation / rework txaus ntshai |
Table 3 - Epoxy txais lub hom phiaj
Txhais lus:
Crescent siab dhau feem ntau txhais tau tiastxaus ntshai
Qhov rai tsis concave / fiber ntau pom feem ntau txhais tau tiasshrinkage los yog tsis txaus replenishment
Daim duab no yuav tsum zaum ntawm ib sab ntawm qhov chaw xa khoom xa tuaj - cov neeg ua haujlwm kawm tau sai dua ntawm daim duab dua li cov ntawv nyeem.
QC chaw kuaj xyuas
Es tsis txhob "ua ntej / thaum / tom qab" rov ua tib yam qauv, ntawm no yog li cas peb feem ntau khiav nws:
