Scale: ODFs feem ntau tuaj yeem ua raws li kev sib txuas ntawm fiber ntau, ua rau lawv tsim nyog rau qhov loj -scale network infrastructures. Hauv cov ntsiab lus, ob qho tib si fiber ntau thaj vaj huam sib luag thiab ODFs ua haujlwm rau kev teeb tsa thiab tswj kev sib txuas ntawm fiber ntau, tab sis lawv cov qauv tsim, kev siv, thiab daim ntawv thov sib txawv. Thaum xaiv ntawm cov cuab yeej no, xav txog nws lub hom phiaj, qhov ntsuas lub network, thiab cov kev xav tau tshwj xeeb hauv network. |
Dab tsi yog qhov Optical Distribution Frame (ODF)?
Ib qho ODF yog qhov chaw sab nraud cog (OSP) fiber ntau optic cables nkag mus rau hauv ib qho chaw thiab tau npaj rau kev faib tawm sab hauv. Thaum lub 288- fiber ntau armored trunk cable tuaj txog ntawm txoj kev, nws tsis txuas ncaj qha mus rau lub hloov. Nws nkag mus rau ODF, qhov twg cov kws tshaj lij strip lub tsho sab nrauv, cais cov fiber ntau ib leeg, thiab fusion-splice txhua tus mus rau ib qho.fiber ntau optic pigtailuas muab qhov kawg txuas (feem ntau yog SC, LC, lossis FC) rau kev hla - txuas mus rau cov kab xaim sab hauv. Hauv ntau qhov kev xa tawm FTTH, ODF kuj tseem muaj PLC splitter modules uas faib ib qho khoom noj fiber ntau rau hauv ntau tus neeg siv khoom ua ntej cov ceg ntoo tawm ntawm tus ncej.
Tag nrho cov kev ua haujlwm splicing yuav tsum muaj kev tiv thaiv ib puag ncig. ODF enclosures shields ilv fusion pob qij txha los ntawm plua plav, ya raws, kev co, thiab kev sib cuag tsis sib haum, thaum swb - tawm splice trays khaws txhua qhov sib txuas nkag mus rau OTDR kuaj yam tsis muaj kev cuam tshuam cov fibers uas nyob ib sab. Integrated cable tswj kev tswj hwm qhov tsawg kawg nkaus khoov vojvoog ntawm txhua txoj hlua, uas tseem ceeb tshaj li cov neeg feem coob paub thaum ntau pua ntawm fibers sib koom ib lub thav duab. Ib pem teb- sawv ODF tuaj yeem haum 576, 864, lossis ntau dua 1,000 kev sib txuas los ntawm kev teeb tsa cov tais ntim khoom hloov pauv- yog vim li cas koj yuav pom lawv hauv cov chaw ua haujlwm hauv nruab nrab thiab cov chaw nkag hauv tsev kawm ntawv uas muaj kaum ob lub tsheb sib txuas.
ODF thiab IDF yog dab tsi?
ODF (Optical Distribution Frame) yog fiber ntau optic tswj cov cuab yeej siv los txiav, txuas, thiab tiv thaiv fiber ntau optic cables hauv xov tooj thiab cov ntaub ntawv chaw ib puag ncig. IDF (Intermediate Distribution Frame) yog qhov chaw faib khoom nruab nrab uas txuas ntxiv kev sib txuas los ntawm Main Distribution Frame (MDF) mus rau cov plag tsev lossis ib cheeb tsam hauv ib lub tsev. ODF tswj xyuas cov teeb liab fiber ntau, thaum IDF faib cov kev sib txuas hauv network rau cov neeg siv kawg.
Dab tsi yog Fiber Optic Patch Vaj Huam Sib Luag Ua?
Lub vaj huam sib luag fiber ntau optic yog lub khib- mounted enclosure uas nthuav tawm cov kab ntawm cov adapters (LC duplex, SC simplex, MTP / MPO) rau pem hauv ntej -fab phaj. Tom qab lub phaj, ua ntej- txiav lub cev cables lossis pigtailed faib fibers txuas mus rau sab nraum qab ntawm txhua lub adapter. Tus kws tshaj lij nrog 3-meterfiber optic thaj qaumntsaws rau sab pem hauv ntej thiab ua kom tiav lub voj voog mus rau cov khoom siv nquag- hloov, lub server, media converter.
Tsis muaj fusion splicer, tsis muaj splice tais. Plug nyob rau hauv ib tug patch qaum coj ib tug tshiab server hauv internet, unplug nws mus decommission. Tsiv, ntxiv, thiab hloov pauv (MACs) tshwm sim hauv vib nas this. Niaj hnub nimno siab - ntom ntom panels ntim 24 LC duplex ports (48 fibers) rau hauv ib chav tsev khib, nrog MTP cassette designs thawb mus rau 96 lossis 144 fibers ib chav tsev. Nyob rau hauv cov ntaub ntawv chaw uas txhua chav racks sawv cev rau cov nqi vaj tse, qhov ntom ntom nti ua rau kev txiav txim siab yuav khoom.
Qhov sib txawv tseem ceeb ntawm ODF thiab Patch Vaj Huam Sib Luag
Ib qho ODF yog qhov uas cov kab hluav taws xob sab nraud tau raug txiav mus tas li los ntawm fusion splicing -cov pob qij txha uas yuav mus tsis tau rau ib xyoo caum. Lub vaj huam sib luag yog qhov txuas tag nrho-raws li: txhua qhov kev sib txuas yog tsim los ua thiab tawg ntawm tes, feem ntau raws li lub network xav tau. Qhov txawv ntawmfiber ntau pigtails thiab thaj cordsmirror no tib yam mus tas li-vim- hloov pauv hloov pauv ntawm qib tivthaiv.
Qhov chaw, kev tsim kho, thiab kev muaj peev xwm tag nrho ua raws li qhov tseeb. ODFs zaum ntawm cov chaw nkag cable, cov chaw faib khoom tseem ceeb, thiab ntsib -kuv chav- ua nrog hnyav- ntsuas steel enclosures, integrated strain nyem, thiab dav routing qhov chaw vim hais tias lawv nyob nraum tuav armored sab nraum zoov trunks. Patch panels nyob rau hauv cov khoom racks ntawm ib sab ntawm cov keyboards thiab routers, sib dua thiab swb -rail-mounted, vim tias lawv txoj haujlwm yog kev tswj xyuas cov hlua khi kom huv hauv ib puag ncig hauv tsev. Thiab thaum ODF kev teeb tsa tuaj yeem tswj hwm ntau txhiab tus fiber ntau hla ntau lub thav duab, thaj vaj huam sib luag ua kom zoo rau qhov chaw nres nkoj- rau- khib-unit ntom- tsawg dua fibers, ntim nruj txaus los ua haujlwm puv khoom txee yam tsis muaj qhov chaw ntsug.
Qhov twg Txhua tus Fits hauv kev xa tawm tiag
Hauv FTTH lossis FTTP network ib txwm muaj, tus neeg nqa khoom -qib ODF zaum ntawm lub chaw ua haujlwm hauv nruab nrab lossis chaw ua haujlwm. Nws tau txais feeder cables los ntawm qaum qaum, splices lawv mus rau hauv tis fibers, thiab feem ntau lub tsevPLC fiber ntau optic splittersuas faib ib qho dej ntws mus rau hauv 16 lossis 32 tus neeg siv khoom. Los ntawm qhov ntawd, cov xaim hluav taws xob xa tawm mus rau txoj kev - theem terminals thiab cov neeg siv khoom thaj chaw.
Cov chaw zov me nyuam ua haujlwm rau lwm txoj hauv kev. Trunk fibers from the campus backbone terminate at an ODF in the main fiber entrance room, but the day-to-day action happens at the row level, where high-density patch panels give administrators the port connections they plug and unplug as workloads shift. Ib ceg chaw ua haujlwm lossis ib leeg -hauv pem teb haum- tawm ua kom yooj yim ntxiv: yog tias tus neeg muab kev pabcuam muab cov khoom xa tawm ua ntej- txiav fiber ntau, lub phab ntsa compact- mount thaj vaj huam sib luag tuav tag nrho qhov chaw yam tsis muaj qhov sib txuas.
Feem ntau zoo - tsim network siv ob qho tib si hauv tandem. Lub ODF tuav lub cev cable txiav thiab ntev - lub sij hawm hla - txuas; lub thaj vaj huam sib luag muab hloov tau kawg -meter txuas mus rau cov khoom siv ports. Qhov txheej txheej txheej no cais cov rhiab splice ib puag ncig los ntawm txhua hnub patching, txo qhov kev pheej hmoo ntawm kev puas tsuaj fiber ntau. Nws kuj txhais tau hais tias thaum lub network nthuav dav tuaj txog - qhov hloov tshiab, kab tshiab ntawm cov servers - tsuas yog kho vajtse uas yuav tsum tau hloov pauv yog nyob rau theem thaj chaw, tsis yog hauv ODF.
Vim li cas Connector Quality Shapes tag nrho System
ODF thiab thaj vaj huam sib luag tau txais kev saib xyuas feem ntau hauv kev sib tham hauv kev npaj, tab sis cov khoom sib txuas ua haujlwm ua haujlwm kho qhov muag tiag tiag. Adapter ports, pigtail terminations, patch cord mating surfaces -lawv tag nrho ntxiv qhov poob, thiab qhov poob ntau ntxiv. Nyob rau hauv 144-fiber ODF pab rau qhov sib cais FTTH ntom, qhov sib txawv ntawm 0.1 dB rau ib qhov sib txuas sib txuas sai sai hla ntau pua khub niam txiv.
Feem ntau ntawm kev ua tau zoo sib txawv ntawm qhov sib txuas zoo thiab qhov tsis zoo nyob hauv lub ferrule. Precision- polished zirconia ceramic ua rau fiber ntau cores raws li nyob rau hauv sub-micron tolerances; Cov ntsej muag tsis zoo ua tiav ua tiav ua rau rov qab poob spikes uas degrade siab -cov cim ceev-tshwj xeeb tshaj yog ntawm 100G-thiab- saum toj no sib txuas sib txuas uas txhua feem kaum ntawm dB suav. Hauv ib qho ODF, qhov sib txuas zoo tseem ceeb dua li ntawm lub vaj huam sib luag, vim hais tias lub pigtail uas tau fusion-spliceed thiab zaum hauv nws lub adapter yog txhais tau tias nyob rau lub neej ntawm cov nroj tsuag cable. Ib tug phemfiber ntau optic connectorfaus rau hauv ib lub tais splice tsis yog ib yam dab tsi uas koj pauv tawm rau hnub Tuesday tav su.
Form factor plays rau hauv ntom thiab.LC connectors nrog lawv 1.25 hli ferrulexa roughly ob npaug ntawm qhov chaw nres nkoj suav ib chav tsev piv rau SC's 2.5 hli daim ntawv zoo, uas yog vim li cas LC dominates niaj hnub cov ntaub ntawv chaw thaj vaj huam sib luag thiab yog nce tshwm nyob rau hauv ODF adapter seem. SC thiab FC tseem tuav hauv av hauv cov nroj tsuag kev sib txuas lus qub uas rov qab sib raug zoo dua li qhov hnyav nce.
Sib piv cov cuab yeej tsim nyog rau koj qhov Network Scale
Ib qho 12-fiber branch office link thiab 1,500-fiber carrier headend yuav luag tsis muaj dab tsi zoo sib xws los ntawm kev xav txog kho vajtse, thiab tshaj qhia txog kev siv nyiaj pov tseg ib yam li kev ntseeg tau raws li kev qhia qis ua rau muaj kev puas tsuaj.
Ntawm qhov kawg sib dua-tsawg dua 48 fibers-ib phab ntsa-mount lossis 1U khib-mount thaj vaj huam sib luag ua haujlwm ntawm nws tus kheej. Piv txwv li, SOHO chaw ua haujlwm txuas mus rau GPON ONT, tsuas yog xav tau 4- lossis 8- chaw nres nkoj fiber ntau txiav vaj huam sib luag ze ntawm lub tsev nkag. Cov cables tuaj txog ua ntej txiav tawm, yog li tsis muaj dab tsi los sib txuas thiab tsis muaj laj thawj los nqis peev hauv ODF-theem infrastructure.
Thaum cov fiber ntau hla mus rau 48- mus rau -288 ntau yam, ib lub vaj huam sib luag yuav tsis txiav nws. Ib tug ntau-pem teb chaw lag luam hauv tsev kawm ntawv lossis cheeb tsam ISP node ntawm qhov ntsuas no tau txais txiaj ntsig los ntawm kev sib koom ua ke ODF rau siab rau ntawm qhov chaw nkag lub ntsiab nrog khib-mount thaj vaj huam sib luag hauv txhua lub txee IDF. ODF muab cov txheej txheem sib txuas kom huv si rau cov kab sib txuas ntawm lub cev, thaum cov kab hauv qab tso cai rau cov neeg ua haujlwm hauv zos IT reroute kev sib txuas yam tsis tau qhib ib lub tais splice. Xaiv txoj caifiber optic connector homntawm txhua qib -APC polish rau ntev -haul splitter feeds, UPC luv luv- ncav cuag cov ntaub ntawv txuas- tiv thaiv teeb meem cuam tshuam los ntawm cascading ntawm txheej. Qhov no kuj yog qhov ntsuas qhov twg daim ntawv lo thiab cov ntaub ntawv pib them; tsis muaj daim ntawv qhia chaw nres nkoj meej txuas ODF splice txoj haujlwm rau cov chaw nres nkoj hauv qab thaj chaw nres nkoj, kev daws teeb meem ib qho txuas tsis tau tuaj yeem noj tag nrho yav tav su.
Tshaj li ob peb puas fibers, ODF dhau los ua kev tsim vaj tsev ruaj khov. Hyperscale data centers thiab telecom central offices ntawm qhov ntsuas no yuav tsum muaj cov qauv hauv pem teb- cov kab ke sawv ntsug nrog cov khoom sib txuas sib txuas, cov kev sib txuas ua ke, thiab pem hauv ntej- nkag mus rau cov vaj huam sib luag uas tso cai rau kub- kev saib xyuas hauv txoj kev tsis muaj kev cuam tshuam cov kev sib txuas uas nyob ib sab. Hardware ntsia ntawm no yuav tsum kav 15 mus rau 20 xyoo. Siab -qibsinglemode pigtailsthiab Hoobkas- sim adapters ntawm qib ODF raug nqi ntau dua, tab sis lawv tshem tawm cov kwj tsis tu ncua ntawm kev daws teeb meem hu xov tooj uas pheej yig cov khoom tsim los ntawm lub sijhawm.
Kev Tswj Xyuas Cable: Qhov Tseem Ceeb Tsis Pom Zoo Uas Txuas Ntxiv Hardware Life
Yuav ua li cas fiber ntau tau dhau los ntawm ODF lossis thaj vaj huam sib luag cuam tshuam rau kev ua haujlwm ntau npaum li qhov kho vajtse nws tus kheej. Khoov lub vojvoog kev ua txhaum cai, tangled thaj qaum, thiab qhov chaw cia slacked tag nrho qhia txog kev poob uas tshwm sim hauv OTDR cov cim tab sis tsis tshua muaj kev thuam ntawm qhov ua rau raug.
Singlemode fiber (tus qauv G.652) muaj qhov tsawg kawg nkaus khoov vojvoog nyob ib ncig ntawm 15 mm, thiab ua txhaum nws qhia txog kev poob macrobend uas ntsiag to tso koj cov peev nyiaj txuas. Nyob rau hauv ib qho ODF, qhov siab tshaj plaws - thaj chaw muaj kev pheej hmoo yog cov pigtail tawm cov ntsiab lus uas cov fibers voj los ntawm splice trays mus rau adapter panels thiab cov slack cia chaw uas ntau fiber ntau tau coiled. Curved routing channels thiab mandrel-style spool tuav nyob rau hauv lub qhov dej-engineered ODF khaws txhua txoj hlua saum lub vojvoog yam tsawg kawg nkaus-txawm tias tus kws tshaj lij rub lub tais tawm rau kev saib xyuas thiab thawb rov qab rau hauv.
Ntawm lub vaj huam sib luag thaj, qhov teeb meem hloov ntawm sab hauv khoov mus rau kev tswj cov hlua sab nraud. A 48-chaw nres nkoj LC vaj huam sib luag nyob rau hauv ib tug tibneeg hu tauj coob cov ntaub ntawv chaw sau ntau cords cascading los ntawm nws lub ntsej muag pem hauv ntej, thiab tsis muaj kab rov tav thiab ntsug cable managers, cov cords tangle, luag rau connector lub cev, thiab thauj lub ferrule caij nplooj ntoos hlav nrog tas li lateral quab yuam. Qhov kev siv tshuab ua kom nrawm nrawm kawg- lub ntsej muag hnav thiab maj mam nce qhov kev poob qis-ib qho teeb meem uas Velcro ties, kev pabcuam kev pabcuam zoo, thiab cov ntawv sau zoo ib yam tuaj yeem tiv thaiv tag nrho yog tias kev qhuab qhia nyob rau hnub ib.
ODF layout kuj tseem cuam tshuam qhov feem ntau cov connectors tau cuam tshuam rau hauv qab. Thaum lub pob tw fibers muaj kev pabcuam txaus slack thiab huv routing txoj kev, OTDR kev ntsuam xyuas thiab tu splices tshwm sim yam tsis muaj rub lossis torquing fiber ntau. Txhua lub sij hawm tus connector tau txais kev ntxhov siab, unplugged, thiab re- zaum, nws lub ntsej muag kawg khaws cov kab mob thiab micro- khawb. Tsim kom muaj tsawg- quab yuam nkag los ntawm qhov pib txhais tau tias tsawg dua kev txij nkawm kov- thiab kev saib xyuas tsawg dua txhais tau tias lub neej txuas ntev dua.
Muab tag nrho ua ke
ODF lossis thaj vaj huam sib luag tsis yog ib qho / lossis kev txiav txim siab rau feem ntau cov tes hauj lwm -nws yog cov lus nug ntawm lub cuab yeej twg mus qhov twg. ODF tshem tawm cov kab hluav taws xob hauv lub cev thiab muab qhov ntev - lub sij hawm hla - txuas. Lub thaj vaj huam sib luag muab cov kws tshaj lij ua cov txheej txheem patching yooj yim ze rau cov khoom siv. Tau txais qhov topology txoj cai yog kauj ruam ib.
Kauj ruam ob yog txhua yam nyob ib ncig ntawm nws: ferrule zoo thiab polish qib sib phim rau txhua txheej, enclosure sizing raws li cov fiber ntau suav es tsis txhob kwv yees, thiab cable routing uas tiv thaiv connectors los ntawm tsis tsim nyog mechanical kev nyuaj siab. Tsis muaj qhov ua haujlwm zoo nkauj, tab sis nws yog qhov sib txawv ntawm cov nroj tsuag fiber ntau uas khiav huv si rau 15 xyoo thiab ib qho uas tsim kev pabcuam hu rau txhua lub hlis twg.
