Tag nrho peb cov fibers sib koom tib hom kab uas hla (8.6-9.5 μm ntawm 1310 nm) thiab core / cladding geometry, uas yog vim li cas lawv splice rau ib leeg yam tsis muaj kev tuav tshwj xeeb. Qhov sib txawv tiag tiag yog khoov kev ua haujlwm.
G652D: Tus Qauv Fiber rau Ntev -Nyob deb Networks
G652D tau ua haujlwm raws li kev lag luam tus neeg ua haujlwm ib leeg - hom fiber ntau rau ntau tshaj peb xyoo lawm. Nws tseem tseem tuav lub cev- kab thiab metro kev teeb tsa thoob ntiaj teb, thiab rau qhov laj thawj zoo: qhov qis qis tshaj qhov kev ncua deb, kwv yees tus cwj pwm splicing, thiab tag nrho rov qab sib raug zoo nrog tag nrho ua ntejG.652 fiber ntau. Yog tias tsis muaj leej twg qhia txog hom fiber ntau ntawm qhov ntev -haul project, G652D yuav luag txhua qhov rub tau.
Qhov twg nws khiav mus rau qhov teeb meem yog dabtsi yog khoov. Qhov tsawg kawg nkaus khoov vojvoog zaum ntawm 30 mm, kwv yees li lub cheeb ntawm lub pob tennis. Nyob rau ntawm txoj kab ncaj nraim khiav los yog sab nraum zoov dav hlau, uas tsis yog qhov teeb meem. Taug kev los ntawm phab ntsa compact-mount enclosure los yog nyob ib ncig ntawm lub ces kaum ntawm lub thaj vaj huam sib luag, tab sis, thiab teeb liab poob pib nce. Txhua qhov nruj tig dhau los ua qhov xau qhov chaw uas lub teeb tawm ntawm qhov tseem ceeb.
Rau tej yaam num uas txoj kev cable nyob twj ywm ncaj, G652D tseem yog tus nqi ntau tshaj -zoo, feem ntau muaj kev xaiv nyob rau hauv lub khw. Nws tsis mus lawm. Tab sis nws yeej tsis tau tsim rau lub quarters nruj ntawm sab hauv cabling, thiab qhov sib txawv yog raws nraim li casG657tsev neeg tau tsim los sau.
G657A1: Khoov-Insensitive, Rov Qab-Compatible
Feem ntau ntawm qhov chaw nkag hauv tsev, cables pib navigating risers, tig cov ces kaum nyob rau hauv txoj kev, thiab dhau los ntawm me me enclosures. G657A1 tau tsim los rau thaj chaw hloov pauv no.
Qhov tsawg kawg nkaus khoov vojvoog poob mus rau 10 hli, uas yog txaus los qhwv cov fiber ntau nyob ib ncig ntawm tus cwj mem yam tsis muaj kev txwv tsis pub tshaj. Rau feem ntau lub tsev - nkag scenarios, txheem phab ntsa-mount thawv, thiab cov fiber ntau faib hubs, uas clearance lis hauj lwm. G657A1 kuj yog tus qauv fiber ntau hauv ntau PLC splitter modules, yog li yog tias koj lub network siv passive optical splitters, koj zoo li twb tau khiav A1 fiber ntau ntawm qee qhov ntawm cov saw hlau.
Ntawm 10 mm radius, macrobend poob ntawm 1550 nm tseem tuaj yeem ncav cuag 0.75 dB ib zaug. Rau ib txoj kev uas tsuas yog ib los yog ob qho kev khoov me ntsis, uas tau txais. Tab sis thaum cov cables yuav tsum dhau los ntawm ntau lub kaum ntse ntse hauv cov thawv me me, tom qab cov phiaj xwm phab ntsa, lossis nyob rau hauv siab - cov tais fiber ntau, cov khoom poob. Qhov ntawd yog qhov uas G657A2 qhov zoo dua los ua si.
G657A2: Tus qauv tam sim no rau FTTH thiab Siab -Kev xa tawm ceev
G.657.A2fiber ntau yog tsim los rau cov ntawv thov uas cabling yuav tsum tau ua kom ntseeg tau nyob rau hauv ib puag ncig los yog complex routing ib puag ncig, xws li hauv tsev broadband tes hauj lwm, neeg rau zaub mov chaw, thiab lwm yam chaw - txwv deployments. Nrog kev txhim kho yooj yooj yim thiab txo cov teeb liab degradation nyob rau hauv ntse khoov, nws outperforms cov pa ib - hom kev xaiv xws liG.657.A1thiabG.652.Dnyob rau hauv demanding installation tej yam kev mob. Nyob rau tib lub sijhawm, nws khaws cia kev sib cuam tshuam nrog G.652.D infrastructure thiab ua kom ruaj khov, muaj txiaj ntsig cov ntaub ntawv xa mus rau network ceev los ntawm 1G txog 400G.
Cov lej ua qhov sib txawv nrog G657A1 nyuaj rau tsis quav ntsej. Ntawm 1550 nm nrog 10 mm khoov vojvoog thiab ib zaug tig, G657A2 tso cai rau qhov poob siab tshaj plaws ntawm 0.1 dB. G657A1 ntawm tib lub vojvoog tso cai 0.75 dB. Thiab G657A2 thawb qhov tsawg kawg nkaus khoov vojvoog ntxiv mus rau 7.5 hli, qhib cov kev xaiv routing uas yooj yim ua tsis tau nrog A1.
FTTH yog dab tsi?
FTTHyog ib qho kev daws teeb meem dav dav uas txuas cov tsev los ntawm kev siv fiber ntau es tsis txhob siv cov tooj liab zoo tib yam -raws li cov kab kawg - mais. Los ntawm kev nqa cov fiber ntau ncaj qha rau cov neeg siv nyob hauv tsev, nws ua rau muaj kev ruaj ntseg network kev ua tau zoo thiab ntau dua cov ntaub ntawv muaj peev xwm. Cov thev naus laus zis no tseem txhawb nqa kev sib npaug ntawm cov dej ntws thiab qis qis, ua rau nws zoo tagnrho rau bandwidth- cov haujlwm hnyav xws li ultra-HD streaming, online gaming, video conferencing, thiab txuas hauv tsev. Nyob rau hauv ib tug raug FTTH nco cable txoj kev, lub fiber nkag mus rau hauv ib lub tsev, txoj kev nce mus rau ib tug riser, tig mus rau hauv ib txoj kev, hla lub phab ntsa -mount box, ces khiav raws lub hauv paus mus txog rau lub optical network davhlau ya nyob twg. Txoj kev ntawd tuaj yeem yooj yim suav nrog tsib lossis ntau qhov khoov nruj dua 15 mm. Nrog G657A1, txhua qhov khoov nti tawm ntawm qhov txuas pob nyiaj siv. Nrog G657A2, qhov poob los ntawm tag nrho cov khoov yuav tseem nyob qis dua 0.5 dB.
Yuav xaiv li cas?
Attenuation ib kilometer, chromatic dispersion, PMD: txhua yam tseem ceeb zoo tib yam thoob plaws peb fibers. Tib qhov sib txawv tiag tiag yog qhov nruj npaum li cas koj khoov.
| Koj qhov Project Scenario | Pom zoo Fiber | Vim li cas |
|---|---|---|
| Ntev -ntaub pob txha lossis metro lub cev | G652D | Tsis nruj khoov. Tus nqi qis tshaj, ua pov thawj ntau xyoo lawm. |
| FTTH faib network (feeder thiab faib ntu) | G652D los yog G657A1 | Nruab nrab khoov ntawm splice kaw. G657A1 ntxiv cov npoo rau qhov nruj dua. |
| FTTH nco cable (tsev nkag rau cov neeg siv khoom) | G657A2 | Muaj ntau txoj hlua khi los ntawm risers, txoj hauv kev, thiab phab ntsa. |
| Data center thaj cords thiab siab - thaj ua rau thaj | G657A2 | Dense trays and small-radius panel guides. Tiv thaiv kom tsis txhob poob qis. |
| Micro cable / cua- tshuab fiber ntau hauv cov kav dej nqaim | G657A2 | Me me txoj kab uas hla quab yuam nruj nkhaus uas phim A2 lub 7.5 hli vojvoog. |
FAQ
Q: Kuv puas tuaj yeem sib xyaw G652D, G657A1, thiab G657A2 ntawm tib qhov txuas?
A: Yog. Tag nrho peb qhov sib koom tib lub core/cladding geometry thiab sib xws hom teb diameters, yog li koj tuaj yeem fusion-splice ib qho kev sib xyaw ua ke nrog tus qauv ib zaug - hom splicer. Qhov kev poob qis nyob qis dua 0.05 dB. Hauv kev xyaum, ntau ntawm FTTH tes hauj lwm khiav G652D ntawm lub cev, G657A1 ntawm ntu faib, thiab G657A2 ntawm qhov poob, txhua qhov sib txuas ua ke ntawm ib txoj hauv kev txuas mus ntxiv.
Q: G657A1 lossis G657A2 Rau FTTH?
A: Rau poob cables, G657A2. Txoj hauv kev hauv tsev hauv tsev yuav luag txhua zaus tsoo ntau qhov khoov nruj qhov twg A2 qhov qis macrobend poob ua rau qhov txuas nyiaj txiag noj qab haus huv. G657A1 ua haujlwm rau sab nraum zoov faib qhov chaw uas khoov yog softer. Qee tus neeg ua haujlwm tau tsim qauv ntawm A2 rau tag nrho cov kev nkag mus rau hauv network tsuas yog khaws ib hom fiber ntau hauv Tshuag.
Q: Puas yog G652D tau ua tiav?
A: Tsis yog. Nws tseem yog qhov kev xaiv zoo tshaj plaws rau qhov ntev - txoj kev tsheb thauj mus los thiab cov kab tsheb ciav hlau uas khoov tsis yog qhov tseem ceeb.
Q: Tus nqi ntau npaum li cas G657A2?
A: Kwv yees li 15-30% saum G652D, nyob ntawm cov chaw tsim khoom thiab xaj ntim. Ntawm FTTH thiab kev ua haujlwm sab hauv tsev, txo qis kev ua haujlwm dua thiab khoov tsawg dua- cuam tshuam txog kev ua tsis tiav yuav ua rau muaj qhov sib txawv.
