Dab tsi yog qhov siv ntau tshaj plawsFiber Connector?
LC connectors tuav kwv yees li 35% ntawm lub lag luam thoob ntiaj teb raws li Grand View Research's 2024 cov ntaub ntawv (grandviewresearch.com). SC los thib ob. MPO/MTP tab tom loj hlob sai nyob rau hauv cov ntaub ntawv chaw nraub qaum daim ntaub ntawv.
Tab sis qhov qeb duas hloov nyob ntawm seb ntu twg koj tab tom saib. Hyperscale cov chaw zov me nyuam yuav luag tsuas yog LC vim yog SFP transceiver standardization. Telecom sab nraum cov nroj tsuag tseem ua haujlwm hnyav ntawm SC. Cov ntawv thov kev lag luam thiab tub rog siv cov khoom sib txuas feem ntau cov neeg tsis tau hnov txog.
Cov lus nug txog kev yuav khoom tsis yog tus connector uas nyiam tshaj plaws - nws yog qhov twg tus nqi koj tsawg tshaj plaws thaum ua tau raws li koj cov kev xav tau tiag tiag.
LC vs SC: Tus nqi sib txawv
Peb tau txais kev thov txhua lub sijhawm uas tus kws tshaj lij muaj spec'd LC thoob plaws lub rooj tsavxwm rau kev tsim kev siv xov tooj. Thaum peb nug yog vim li cas, cov lus teb feem ntau yog ib yam zoo li "tus qauv tam sim no" lossis "peb siv LC txhua qhov chaw."
LC tau dhau los ua qhov tseem ceeb hauv cov chaw khaws ntaub ntawv vim qhov ceev. Lub 1.25mm ferrule yog ib nrab ntawm SC's 2.5mm, uas txhais tau tias 144 duplex ports ib 1U vaj huam sib luag piv rau 72 rau SC. Nyob rau hauv ib qho chaw khiav ntau pua txhiab qhov kev sib txuas, qhov kom zoo dua qhov ntom ntom tau txhais ua ntau lab tau txais kev cawmdim ntawm qhov chaw hauv pem teb thiab cua txias.
Hauv lub txee sab nraum zoov nrog 24 qhov chaw nres nkoj? Qhov kev sib cav ntom ntom ploj tag nrho.
Nov yog cov lej tiag tiag zoo li ntawm nruab nrab -loj xa tawm:
| Txuas | Tus nqi (5k-10k qty) | 8,000 units tag nrho | Installation Notes |
|---|---|---|---|
| LC UPC | $2.50-4.00 | $20,000-32,000 | Yuav tsum tau precision ntau, qeeb hauv huab cua txias |
| SC UPC | $1.50-3.00 | $12,000-24,000 | Yooj yim tuav nrog hnab looj tes, ua haujlwm nrawm dua |
| LC APC | $3.50-5.50 | $28,000-44,000 | Yuav tsum tau rau PON/CATV nkaus xwb |
| SC APC | $2.50-4.50 | $20,000-36,000 | Tib daim ntawv thov, tus nqi qis dua |
Qhov sib kis ntawm LC thiab SC khiav 25-40% nyob ntawm qhov ntim thiab tus neeg xa khoom. Ntawm 8,000 kev txiav tawm, koj tab tom saib ntawm $ 8,000-12,000 qhov sib txawv tsuas yog ntawm cov khoom sib txuas-ua ntej suav nyiaj rau kev ua haujlwm sib txawv los ntawm SC txoj kev ua haujlwm yooj yim dua.
Peb tau hais ib cheeb tsam ISP xyoo tas los uas hloov los ntawm LC rau SC tau cawm lawv qhov chaw nyob ib puag ncig $ 50k ntawm 12,000-poob FTTH nthuav dav. Lawv Ameslikas spec'd LC vim lawv cov ntaub ntawv chaw siv nws. Rau lub hlis mus rau kev xa mus, lawv tus thawj saib xyuas teb tau nug txog kev hloov pauv SC txawm li cas los xij vim tias cov kws tshaj lij tau ua rau muaj kev sib txuas LC hauv Minnesota lub caij ntuj no.
MPO rau siab -Speed Backbone: Thaum Math Flips
Tshaj 40G, kev suav hloov pauv tag nrho. MPO / MTP connectors ntim 12 lossis 24 fibers rau hauv ib qho kev sib txuas, ua rau cov khoom sib txuas uas 100G / 400G transceivers xav tau.
Ib -unit nqi zoo li phem-$50-80 rau MPO-12 piv rau $3-4 rau LC duplex. Tab sis lub installation economics rov qab hais tias:
| Qhov xwm txheej | Field-Terminated LC (12 fibers) | Ua ntej-Terminated MPO-12 |
|---|---|---|
| Khoom siv | ~$40 | ~$65 |
| Lub sijhawm nruab | 3-6 teev | 10 feeb |
| Labor @ $75/hr | $225-450 | $12 |
| Lub sijhawm kuaj | 45 min ib kawg | Hoobkas tau ntawv pov thawj |
| Teb yuam kev tus nqi | 5-10% | <1% |
| Tag nrho cov nqi nruab | $300-550 | $80-100 |
Corning cov ntaub ntawv luam tawm los ntawm EDGE Rapid Connect deployments qhia tau hais tias 70% kev txhim kho lub sij hawm txo thiab kev ua yuam kev poob los ntawm ib ncig ntawm 8% mus rau qis dua 1% (corning.com). Tus nqi rov ua dua los ntawm kev ua yuam kev ib leeg ib leeg feem ntau tshaj MPO tus nqi.
Rau cov pob txha khiav uas nyob li qub, MPO yeej. Rau thaj chaw ua haujlwm nrog nquag txav / ntxiv / hloov pauv, kev sib txuas ntawm LC tseem ua rau muaj kev nkag siab zoo vim tias koj tsis tau them rov qab - txiav tawm ntawm kev teeb tsa.
Cov ntsiab lus technical uas qhov tseem ceeb
Cov ntawv sib piv feem ntau siv cov nplooj ntawv piav qhia txog dab tsi LC thiab SC sawv cev rau (Lucent Connector thiab Subscriber Connector, yog tias koj nyiam). Qhov ntawd tsis muaj txiaj ntsig rau kev txiav txim siab yuav khoom. Qhov tseem ceeb:
Ferrule qib
yog ib yam uas feem ntau buyers yeej tsis nug txog. Zirconia ceramic ferrules muaj bore diameters li ntawm 124μm mus rau 127μm kom phim cov kev hloov pauv hauv fiber ntau cladding. Orbray, leej twg pioneered ceramic ferrule manufacturing nyob rau hauv 1987, tswj kev kam rau siab nyob rau hauv 1 micrometer-tab sis qhov precision tsuas yog pab yog tias qib ferrule phim koj cov fiber ntau (orbray.com). Pheej yig connectors siv ib qib rau txhua yam. Qhov tshwm sim yog 0.05-0.1dB ntxiv qhov poob qis ib qho kev sib txuas uas sib txuas ntawm cov txuas ntev.
APC vs UPC
tsis yog qhov zoo sib txawv- nws yog qhov yuav tsum tau ua daim ntawv thov. APC (ntsuab, 8℃kaum sab kawg ntawm lub ntsej muag) yog qhov yuav tsum tau ua rau PON, CATV, thiab RF- dhau- fiber ntau vim tias lub kaum sab xis ntawm lub ntsej muag qhia pom lub teeb rau hauv lub cladding es tsis yog rov qab mus rau qhov chaw. UPC (xiav, perpendicular kawg lub ntsej muag) ua haujlwm zoo rau tus qauv Ethernet.
Txoj cai tseem ceeb: tsis txhob koom nrog APC rau UPC. Lub angular mismatch tsim kom muaj qhov sib txawv ntawm huab cua uas thawb qhov poob siab tshaj 4dB thiab ua rau lub cev puas tsuaj rau ob lub ferrules. Kuv tau pom 50G txuas mus caum phantom yuam kev rau ob hnub ua ntej ib tug neeg pom lub xiav jumper ntsaws rau hauv ib lub taub hau ntsuab. Txhua connector thiab adapter nyob rau hauv koj infrastructure yuav tsum yog ib hom los yog lwm yam, tswj los ntawm koj BOM specs.
FC keying qauvtseem coj cov neeg mus rau hauv cov txheej txheem qub txeeg qub teg. FC/APC muaj nyob rau hauv ob qhov tseem ceeb dav dav: 2.0mm (txo, ib daim ntawv sau npe) thiab 2.14mm (NTT, ob daim ntawv sau npe). Lawv saib zoo ib yam tab sis tsis mate kom raug. Yog tias koj tab tom tuav cov kev sib txuas lus qub nrog FC connectors, xyuas seb tus qauv twg koj cov cuab yeej siv tam sim no siv ua ntej xaj hloov.
Dab tsi tshwm sim hauv Field Failures
Lub rooj sab laj PCTalk muaj cov xov xwm rov hais dua uas mus qee yam xws li: "fiber txuas ntawm lub tsev poob qis, kuv cov kev hloov pauv xov xwm tau cim ntau hom tab sis lub tsev khiav yog tib hom - hom, Kuv puas tuaj yeem siv multimode jumpers ntawm ib qho -mode cable?"
Tsis muaj . 62.5/125μm (OM1) thiab 50/125μm (OM3/OM4) multimode fiber ntau yuav tsum tau multimode transceivers thiab jumpers. Tib - hom xav tau ib zaug - hom txhua yam. Kev sib xyaw ua ke tsis tsim "kev poob ntxiv"- nws tsim cov teeb liab ua tsis tiav lossis tsis sib xws uas yuav luag tsis tuaj yeem daws teeb meem.
Qhov no tshwm sim vim hais tias ib tug neeg txiav txim "fiber patch cables" yam tsis tau qhia meej hom, lossis tus kws tshaj lij rub txhua yam hauv lub tsheb. Xim coding pab (daj=ib leeg-mode, txiv kab ntxwv=OM1/OM2, aqua=OM3/OM4) tab sis tsis yog cuav. Koj tus txheej txheem tau txais kev tshuaj xyuas yuav tsum tau txheeb xyuas hom kev sib raug zoo meej.
Kev kis kab mob yog lwm qhov tas mus li. Kev lag luam kwv yees muab cov khoom sib txuas qias neeg ua rau 85-90% ntawm fiber ntau network faults. Koj tsis tuaj yeem ntsuas qhov tsis huv ntawm qhov muag-tus ntiv tes uas zoo li huv ntawm lub qhov muag yuav ua tsis tau raws li qhov muaj fiber ntau. Txhua qhov kev sib txuas yuav tsum tau tshuaj xyuas thiab ntxuav ua ntej sib yuav, uas txhais tau hais tias koj cov khoom siv hauv teb yuav tsum muaj cov cuab yeej tshuaj xyuas thiab IPA cov khoom siv tu, thiab koj cov kws kho mob yuav tsum siv lawv tiag tiag.
Supplier Qualification Questions
Cov ntaub ntawv dav dav txhua tus thov cov specs zoo sib xws vim txhua tus luam tawm los ntawm TIA thiab IEC cov qauv. Cov lus nug uas qhia qhov tob ntawm kev tsim khoom:
Dab tsi nkag poob koj lav - tus nqi raug lossis siab tshaj? Koj tus txheej txheem Cpk ntawm qhov parameter yog dab tsi? (Yog tias lawv tsis paub tias Cpk txhais li cas, qhov ntawd yog cov ntaub ntawv.)
Puas yog koj lub rooj sib tham MPO nkoj nrog cov ntaub ntawv kuaj ib tus zuj zus, lossis tsuas yog qhov phem tshaj - cov nqi rau lub rooj sib txoos?
Rau APC connectors, koj puas kuaj qhov kawg - lub ntsej muag lub kaum sab xis thiab lub vojvoog ntawm IEC 61755-3-1, lossis tsuas yog kuaj xyuas qhov poob? (Cov teeb meem geometry tuaj yeem dhau IL xeem tab sis ua rau muaj teeb meem nyob rau hauv thermal cycling lossis rov mating.)
Dab tsi yog koj lub sijhawm ua haujlwm tam sim no rau SC / APC hauv kom muaj nuj nqis 5,000? Rau MPO-24 APC hauv kom muaj nuj nqis 200? (Qhov sib txawv ntawm cov lus hais thiab lub sijhawm ua haujlwm tiag tiag qhia koj txog cov khoom muag piv rau kev tsim khoom-rau-order.)
Cov ntsiab lus
LC feem ntau yog siv vim tias cov chaw zov me nyuam tau tsav cov txheej txheem los ntawm SFP transceiver interfaces. SC tseem tshuav tus nqi ntau dua - siv tau rau kev siv xov tooj cua, FTTH poob, thiab txhua qhov kev xa tawm uas qhov ceev tsis yog qhov tseem ceeb. MPO / MTP tau dhau los ua lub neej ntawd rau 40G + cov pob txha caj qaum qhov chaw uas cov nqi zog ua haujlwm tswj hwm cov nqi khoom siv.
