Ntawm no yog qhov txog ntawm Minv couplers uas tsis muaj leej twg qhia koj upfront: lawv tsis yog qee lub ntsiab lus ua rau koj lub network ua haujlwm zoo li nws yog ntawm steroids. Tab sis nug ib qho installer uas tau nyob hauv lub trenches rau ib xyoo caum lossis ntau dua, thiab lawv yuav qhia koj - yog qhov tseeb me ntsis tseem ceeb dua koj xav.
Dab tsi peb yog tiag tiag tham txog ntawm no
Saib, ib qho MTP Coupler yog yeej ib qho adapter transapter. Zaum hauv koj lub vaj huam sib luag, ua rau koj ua khub ob tus MTP innector rov qab -- rov qab. Suab yooj yim, txoj cai? Thiab mechanically, nws yog. Ob tus ferules tuaj ua ke, kev ua tiav pins ua lawv txoj haujlwm, lub teeb hla dhau. Tab sis ntawm no yog qhov twg nws tau nthuav - thiab qhov twg tag nrho "txhim kho kev sib txuas" lus nug ua tsis ncaj dua li}} {}} tsis muaj lus teb.
Cov Neeg Ua Haujlwm Ua Haujlwm
Cia peb pib nrog kev poob siab, vim tias yog txhua tus neeg obsesses dhau. Ib qho khoom zoo meTP Coupler - thiab kuv tau hais txog qhov tiag tiag los ntawm peb cov chaw tsim khoom, tsis yog cov khoom siv dag, feem ntau yuav ntxiv ib yam dab tsi xws li 0.25 rau 0.5 DB ntawm kev poob siab. Qee tus neeg tseem ceeb tshiab tshaj tawm thov cov lej tsawg.
Tam sim no, puas yog "txhim kho" kev sib txuas tau muab piv rau dab tsi? Piv rau kev hais ncaj qha mating ob transceivers? Tsis yog, pom tsis pom tseeb - txhua qhov kev sib txuas lus ntxiv ploj. Tab sis ntawm no yog qhov kev tshawb xyuas kev muaj tiag: feem ntau cov ntaub ntawv chaw ua haujlwm tsis tuaj yeem ua haujlwm tsis muaj qee yam ntawm cov txheej txheem sib sau ua ke. Koj xav tau tus ntoo khaub lig- Txuas, koj xav tau lub peev xwm rov kho dua, koj yuav tsum tau ntsuam xyuas tus kheej ntawm lub network. Sim ua txhua yam uas muaj kev sib txuas lus ncaj qha lossis cov khoom sib txuas ncaj qha. Hmoov zoo nrog tus txij nkawm zaj npau suav phem.
Qhov twg couppers yeej txuag koj cov nqaij npuas kib
Kuv tau tham nrog ib tug txiv leej tub lub hli dhau los - ua haujlwm nyob rau ntawm nruab nrab - qhov loj me corocation chaw hauv Phoenix. Lawv tau nthuav lawv 100g kev xa tawm, thiab nws hais qee yam uas nyam nrog kuv. Lawv cov txheej txheem qub siv siv cov LC chav sib txuas thiab qee cov khoom mpo thaum ntxov uas tau ua cov khoom lag luam ferule zoo heev. Txhua zaus lawv yuav tsum tau rov qab kho dua - uas tau ua rau txhua lub lim tiam vim tias tsuas yog li cas Colo ua haujlwm Drift. Tsis yog kev puas tsuaj, tab sis cov teeb liab txaus teeb tsa uas lawv tau ua kev kuaj mob ntau dua li lawv xav tau.
Tom qab lawv tau qauv ntawm MTP cov lus choj txuas hla lawv cov kev tsim kho tshiab, qee yam nyiam tshwm sim. Tsis tej yees duab, tsuas yog ... tsawg dua taub hau. Lub ntab ferrule tsim qauv txhais tau tias thaum ib tug neeg tsoo lub cable (thiab ntseeg kuv, cov kab ke tau mus tsoo), qhov kev sib txuas tsis tau mus flaky tam sim ntawd. Qhov kawg xaus -} ntsej muag geometry txhais tau tsawg dua kev sib txawv ntawm cov ntsiab lus sib txuas.
Puas yog lub coupllers lawv tus kheej "txhim kho" kev sib txuas? Tej zaum tsis yog nyob rau hauv raw specs. Tab sis lawv txhim khoyeejKev sib txuas, uas nyob rau hauv ib qho chaw ntau lawm tej zaum yuav yog qhov tseeb ntxiv.
Cov polarity yam tsis muaj leej twg xav tau nrog
Ntawm no yog lwm lub kaum sab xis. MTP Couplers tuaj hauv tus yuam sij-} {} {} {} {17}-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} kev teeb tsa. Tau txais qhov tsis ncaj ncees no, thiab koj tsis kis ib yam dab tsi - koj qhov tseem ceeb wired xa mus rau kis thiab tau txais. Teb tsis yog - oob khab.
Tab sis - thiab qhov no yog cov couplers tau muaj txiaj ntsig zoo heev - muaj txoj cai coupler hom txhais tau tias koj tuaj yeem tswj cov kab ke kom tsim nyog los ntawm koj cov kev cai sib sau ua ke rau txhua qhov xwm txheej. Txoj kev b polarity? Koj xav tau tus yuam sij -}- {tus yuam sij {}} down couplers. Txoj kev A lossis C? Key -} - rau {{Key- Up.
Qhov no tsis yog theoretical. Kuv tau pom cov tuam txhab network uas lawv tau sim ua kom pheej yig thiab tsuas yog xaj txhua txoj hauv kev hauv Tshuag, kwv yees "MPO yog MPO." Rau lub lim tiam tom qab lawv muaj kev daws teeb meem vim li cas ib nrab lawv 40g txuas yuav tsis qhia, thiab nws hloov tawm ib tug neeg tau nruab rau qhov tseem ceeb tshaj plaws li cas {}} Txuas. Tus coupler tsis txhim kho lawv cov kev sib txuas - tab sis qhov tsis ncaj ncees lawm coupler paub tseeb tua nws.
Density trade - Offs (vim tias tsis muaj dab tsi pub dawb)
Ntawm no yog ib yam dab tsi ua cov ntawv cim generaled tshaj: yog, MTP co couples cia koj ntim txoj kev sib txuas ntxiv rau LC lossis Scr. Cov lej no yog tiag tiag - 144 fibers nyob rau hauv cov chaw uas yuav tau muaj 24 txuas ntxiv nrog tus tshiab ultra {} high- kub panels.
Tab sis kev ua kom lub cev ua kom tsim nws cov teeb meem. Puas tau sim ua haujlwm ntawm lub nkoj Midulated Midtas sim no? Kev nkag mus yog txaus ntshai. Koj cov ntiv tes tsis haum. Koj yuav tsum tau lub teeb nyem kom pom qhov koj ua, tab sis tsis muaj chaw los tuav lub teeb nyem thiab muab cov connipulate txuas tib lub sijhawm. Thiab Vajtswv pab koj yog tias koj xav tau kom ncav cuag ib yam dab tsi hauv nruab nrab ntawm lub vaj huam sib luag.
Kuv tsis tau hais tias tsis siv siab - ntom MTP Coupler teeb. Tsuas nkag siab txog kev ua lag luam - tawm. Koj nce chaw nres nkoj ceev tab sis poob qee cov tswv yim serviceability. Rau cov ntawv thov caj qaum uas koj tsis tas li plawg? Kev lag luam ua lag luam zoo - tawm. Rau kev ua kom muaj zog ntau dua? Tej zaum xav ob zaug txog kev mus rau qhov tseem ceeb tshaj plaws.
Cov taub hau tu
Qhov no tsav kuv vwm, thiab yuav luag tsis muaj leej twg tham txog nws ua siab ncaj. MTP ferrules muaj 12 lossis 24 cov fibers hauv lawv (qee zaum ntxiv). Qhov ntawd yog 12 lossis 24 lub ntsej muag kawg uas txhua tus yuav tsum tau huv rau kev ua haujlwm kho qhov zoo.
Lc txuas? Koj tuaj yeem tshuaj xyuas lawv tau zoo nkauj yooj yim. Ntxuav lawv nrog ib tug - nyem nyem ntxuav. Yuav siv sijhawm 30 feeb yog tias koj tau txhij txhua.
MTP? Koj xav tau cov tshuaj ntsuam xyuas kom zoo uas tuaj yeem saib cov ferrule array. Cov cuab yeej ntxuav muaj - cov tshuaj ntxuav cov khaub noom ntoo, cov ntaub so tshwj xeeb - tab sis cov txheej txheem muaj kev koom tes ntau dua. Thiab cov txuas lawv tus kheej nthuav kev plua plav thiab paug, tshwj xeeb tshaj yog nyob rau hauv cov kev sib dhos pin qhov.
Kuv tau pom cov tes haujlwm uas yog cov cuab yeej cuab tam yog specrastructure yog specuality, zoo couplers thoob plaws, tab sis cov peev txheej poob yog maj mam nkag mus thoob plaws ntau qhov sib txuas. Hauv paus ua? Tsis muaj leej twg tau tu lub couplers thaum niaj hnub saib xyuas. Hloov tawm cov roj cughead tawm hauv koj lub panels tau txais tsuas yog qias neeg raws li cov txuas uas koj tau txuas mus rau lawv.
Yog li ua MTP Couplers txhim kho kev sib txuas? Tsuas yog tias koj ua tau zoo tswj lawv kom raug. Txwv tsis pub koj tsuas yog tsim 12 lossis 24 qhov kev ua tsis tiav cov ntsiab lus hloov 2.
Thaum cov ntsiab lus tsis txhob qhia tag nrho zaj dab neeg
Ntawm no yog qhov txawv tshaj plaws uas kuv tau pom: ob couplers tuaj yeem muaj cov ntawv sib tw zoo ib yam, tib yam rov qab poob, tab sis ua txawv ntawm kev coj ua. Vim li cas?
Kev ua kom nruj, feem ntau. Cov couplers zoo tiag tiag muaj kev tswj hwm kev ua kom nruj dua qhov tso tawm, cov txheej txheem PIN qhov loj me, thiab lub caij nplooj ntoo hlav. Qhov no txhais tau tias thaum koj ntsaws ruaj ruaj, lub ferrule zaum muaj ntau dua. Koj tsis sib ntaus sib tua kom tau txais kev sib txuas zoo.
Nws kuj tseem muaj cov qauv tsim vaj tse. Qee qhov txuas txuas tau muaj cov kab ke zoo dua los yog Cable tswj cov yam ntxwv uas txo cov hauv paus ntawm kev tso sab thauj ntawm cov ferrule. Lwm tus tsuas yog ib tug neeg rov qab los ntawm bulkhead adapter, thiab yog tias ib tug neeg txoj kev khiav txoj kev cable nrog cov united nro, koj tau txais ferrule misalignment thiab poob siab.
Cov ntaub ntawv cov ntaub ntawv yuav tsis ntes cov khoom no. Koj yuav tsum nruab ob peb txhiab ntawm lawv los tsim kev xav.
Adapter hom thiab thaum lawv tiag tiag
Ib yam dab tsi uas kuv xav ntau tus neeg to taub: Cov lus "MTP Coupler" thiab "MTP Adapter"Tau siv cov zoo nkauj sib pauv hauv lub tshav pob, tab sis technically ib qho kev hloov pauv ntawm MTPLER Peb tau sib tham txog kev hloov pauv ntawm yoov.
Qhov sib txawv ntawm qhov tseem ceeb thaum koj xaj seem. Kuv tau yuav cov chaw haujlwm xaj "MTP adapters" kev xav lawv tau txais kev sib koom tes yog polarity- recersing kev hloov kho tau rau cov ntawv thov tshwj xeeb. Peb {-} Lub sij hawm ua lub sijhawm kom tau txais cov ntu yog, thiab lub sijhawm no lub sijhawm teeb tsa yog tshuab.
Kuv cov lus qhia? Yuav decringly tshwj xeeb thaum spec'ing cov khoom no. "12 {- Fiber ntau MTP Coupler, tus key}}}} {4} {} Yog lawm, nws yog ntau lo lus. Yog, nws pom tau pedantic. Tab sis nws tiv thaiv qhov tsis ncaj ncees lawm uas qhia tau ntawm cov chaw haujlwm.
Lub neej yav tom ntej tsis yog ib txwm zoo dua (tab sis qee zaum nws yog)
Lub tshiab tiam tshaj plaws MTP couplers yog hais txog qee qhov teeb meem tiag tiag. Teb {- swappable poj niam txiv neej thiab polarity xaiv yog genuinely pab tau yog tias koj ua ntau qhov kev faib khoom. Qee qhov kev sib che enhanced lub cev hloov (EPC) polishing specs yog qhia cov kev poob qis hauv kev kuaj sim.
But here's my skeptical take: a lot of these improvements matter most in extremely high-performance applications or very long-reach scenarios where you're counting every tenth of a dB. Rau cov ntaub ntawv cov ntaub ntawv cov khoom lag luam khiav 100 meters lossis tsawg dua? Lub 2015-era couplers ua haujlwm zoo. Lub 2025 couplers kuj ua haujlwm zoo.
Tshwj tsis yog koj txhim kho txhua yam lossis lub tsev tshiab, Kuv tsis paub meej txog cov khoom tshiab uas sawv cev rau qhov yuav tsum {}}}}}}}}}}}}}}}}}}}}}}}}}} muaj kev txhim kho rau cov kev sib txuas ntau tshaj plaws. Txawm hais tias kuv mam li lees lub teb - Tsis tau txais kev ntseeg siab dawb huv si hauv ob peb txoj haujlwm uas peb tau txiav txim siab Cable hom.
Yog li ... lawv puas txhim kho kev sib txuas?
Tom qab txhua yam uas: nws nyob ntawm qhov koj muab piv rau, thiab koj txhais li cas los ntawm "txhim kho."
Piv rau tsis muaj tsis muaj cov txheej txheem sib txuas ntawm txhua tus? Pom tseeb yog - koj xav tau qee txoj hauv kev npaj thiab tswj cov kev sib txuas fiber ntau ntawm cov.
Muab piv rau LC Duplex rau parallel Optics Daim Ntawv Thov? Yog, vim tias koj cia tsis tau 40g lossis 100g pangel kis nrog LC DUPLEX. Tsis ncaj ncees lawm txuas rau txoj haujlwm.
Piv rau kev sib txuas ncaj qha lossis kev sib txuas tas mus li? Yog lawm rau kev yoog raws thiab kev pabcuam, tsis muaj rau qhov tsis meej teeb liab.
Piv rau pheej yig tsis muaj -} Lub npe MPO Couplers los ntawm cov neeg xa khoom? Tiag tiag yog, yog tias koj tau siv Metp kom zoo rau Metp-} branded Cheebtsam. Tab sis koj tseem them 3-4 x ntxiv rau ib chav.
Cov lus teb ncaj ncees yog tias MTP couplers yog ib qho tsim nyog cov khoom siv tsim nyog rau niaj hnub no - qhov kev sib tw fiber ntau. Lawv tsis txhim kho kev sib txuas hauv qee txoj kev tej yam yees siv, tab sis lawv ua kom haum txuas ntxiv uas tsis tuaj yeem siv tau. Thiab thaum siv cov qauv kom raug - txoj cai polarity, kom zoo tswj, zoo sib xws - lawv ntseeg tau txaus uas koj tsis xav txog lawv.
Qhov twg, hauv kev tsim kho vaj tse, yog hom kev qhuas tshaj plaws uas koj tuaj yeem muab qee yam. Nws nyuam qhuav ua haujlwm, yog li koj tuaj yeem tsom rau cov teeb meem tiag tiag.
