G.657 Fiber Rau FTTH: Cov neeg yuav khoom yuav tsum kuaj dab tsi ua ntej xaj?
Sep 21, 2026| G.657 Fiber rau FTTH: Cov neeg yuav khoom yuav tsum kuaj dab tsi ua ntej xaj?
Yog tias koj muab khoomkhoov insensitive fiber G657, lo lus nug tseem ceeb tsis yog qhov G.657 fiber ntau yog dab tsi. Cov neeg yuav khoom yuav tsum tau txiav txim siab seb G.657 qeb twg haum rau cov qauv hauv lub network, seb cov fiber ntau puas sib haum nrog G.652.D systems uas twb muaj lawm, seb nws txoj haujlwm dabtsi yog khoov haum rau qhov chaw nruab, thiab seb tus neeg muag khoom puas tuaj yeem tswj cov khoom ruaj khov.
Rau FTTH cov haujlwm hauv Tebchaws Meskas, Lub Tebchaws Yelemees, Nyiv, Kaus Lim Qab Teb, thiab Tebchaws Askiv, cov xwm txheej no tseem ceeb zuj zus ntxiv vim tias cov fiber ntau txuas ntxiv txuas ntxiv thiab cov network uas twb muaj lawm tau hloov kho dua tshiab.
1. Ua ntej lees paub tias koj xav tau G.657 Hloov tus qauv G.652.D
ITU-T G.657 txhais cov yam ntxwv rau ib leeg- hom kho qhov muag fiber ntau nrog kev txhim kho khoov kev ua haujlwm. Qeb A suav nrog G.657.A1 thiab G.657.A2, uas yog tsim los muab cov macrobending poob qis dua li cov pa fiber ntau raws li cov xwm txheej tau teev tseg.
Rau FTTH, FTTB, sab hauv tsev cabling, ODF daim ntaub ntawv, thiab siab -ntaus fiber ntau routing,khoov insensitive ib hom fiber ntautuaj yeem cuam tshuam tshwj xeeb thaum qhov chaw teeb tsa tsuas yog txwv.
Yog tias koj tab tom ntsuas ib yam khoom tshwj xeeb, saib pebKhoov Insensitive Tib Hom Fibernplooj ntawv khoom rau cov lus qhia ntxiv.
Tsis txhob muab tsuas yog "G.657 Fiber" hauv RFQ
Kev ua tiav RFQ ntau dua yuav tsum txheeb xyuas cov cai hauv qab no:
- G.657.A1 or G.657.A2
- G.652.D compatibility
- Yuav tsum tau ua haujlwm wavelength ntau yam
- Attenuation xav tau
- Txoj kab uas hla (MFD)
- Cladding txoj kab uas hla
- Macrobending poob
- Cov ntaub ntawv pov thawj qib
- Txheej txheej thiab xim
- Fiber ntev thiab ntim
Qhov tseeb dua qhov kev qhia tshwj xeeb tau txhais, qhov yooj yim dua nws yog kom tswj tau qhov sib xws thaum hloov cov neeg xa khoom lossis tso cov xaj rov qab.
2. G.657.A1 vs. G.657.A2: Tsis Txhob Xaiv Tsuas yog "Higher Khoov Resistance"
Qhov no yog ib qho teeb meem tshwm sim thaum yuav G.657 fiber ntau.
G.657.A1 thiab G.657.A2 yog ob qho tib si Qeb A khoov-insensitive ib leeg- hom fibers, tab sis lawv yog npaj rau kev khoov sib txawv thiab kev teeb tsa.
Yuav Ua Li Cas Cov Neeg Yuav Xaiv Ntawm A1 thiab A2?
Rau tus qauv FTTH routing:thawj zaug paub meej tias G.657.A1 twb ua tau raws li qhov yuav tsum tau ua ntawm kev teeb tsa.
Rau cov terminals compact, me me cable qauv, nqaim routing qhov chaw, los yog siab - ceev installation:soj ntsuam seb puas yuav tsum tau G.657.A2.
G.657.A1 feem ntau cuam tshuam nrog 10 hli siv lub vojvoog tsim, thaum G.657.A2 tuaj yeem txhawb nqa ntau qhov kev sib khi, nrog rau cov ntawv thov siv 7.5 hli siv lub vojvoog tsim.
Yog li kev txiav txim siab yuav khoom yuav tsum yog raws li cov qauv cable, qhov chaw teeb tsa, thiab cov kev xav tau ntawm lub network tiag tiag es tsis yog tsuas yog xav tias A2 yog qhov kev xaiv zoo dua.
3. Tsis txhob muab piv rau tus nqi ib kilometer xwb
Thaum yuav khoomG.657 FTTH fiber ntau, tus nqi yog ib qho tseem ceeb, tab sis qhov tseeb qhov project tus nqi koom nrog ntau tshaj li tus nqi fiber ntau nws tus kheej.
Fiber specification → Cable design → Installation → Splicing → Field performance → Replacement risk
FTTH fiber ntau yuav dhau los ntawm cov thawv xa khoom, cov khoom siv hluav taws xob, cov chaw sab hauv tsev, thiab cov khoom siv compact. Raws li qhov chaw teeb tsa ua me me, khoov kev ua tau zoo dhau los ua qhov tseem ceeb rau kev tswj hwm qhov kev ua haujlwm kho qhov muag yuav tsum tau ua tom qab kev teeb tsa.
Kev lag luam tseem tab tom txav mus rau qhov siab dua fiber ntau thiab ntau cov qauv siv cable. Qhov no txhais tau tias cov neeg yuav khoom yuav tsum tsis txhob nug nkaus xwb:
Cov lus nug tseem ceeb tshaj plaws yog:
4. Kos G.652.D Compatibility
Hauv kev lag luam fiber ntau xws li Tebchaws Meskas, Lub Tebchaws Yelemees, Nyiv, Kaus Lim Qab Teb, thiab Tebchaws Askiv, ntau qhov haujlwm cuam tshuam nrog kev nthuav dav thiab kev hloov kho dua tshiab dua li kev sib txuas tshiab.
Vim li no, lub compatibility ntawmG.657 A1 fiber ntaulos yogG.657 A2 fiber ntaunrog rau txoj haujlwm G.652.D yuav tsum tau lees paub thaum lub sijhawm yuav khoom.
5. G.652.D vs. G.657.A1 vs. G.657.A2
| Hom Fiber | Hom Positioning | Khoov yuav tsum tau | Tej kev siv |
|---|---|---|---|
| G.652.D | Cov pa ib zaug - hom fiber ntau | Standard routing tej yam kev mob | Backbone networks thiab general optical networks |
| G.657.A1 | Khoov- optimized ib zaug - hom fiber ntau | Reference tsim vojvoog nyob ib ncig ntawm 10 mm | FTTH, nkag mus rau tes hauj lwm, sab hauv cabling |
| G.657.A2 | Tighter - khoov ib zaug - hom fiber ntau | Reference tsim vojvoog nyob ib ncig ntawm 7.5 mm | Compact routing thiab siab - kev teeb tsa ceev |
6. Nug tus neeg muab khoom kom paub tseeb cov ntaub ntawv xeem
Thaum yuav khoomkhoov insensitive fiber G657, buyers yuav tsum tsawg kawg yog xyuas cov nram qab no tsis:
G.657.A1 / G.657.A2
G.652.D compatibility qhov twg yuav tsum tau
Paub meej tias qhov ntau yam ua tau raws li qhov yuav tsum tau ua
Txheeb xyuas qhov tseem ceeb wavelength xws li 1310 nm thiab 1550 nm
Paub meej tias ua raws li qhov xav tau ntawm qhov project
Paub meej tias yuav tsum tau specification, xws li 125 μm
Tshawb xyuas kev ua tau zoo ntawm lub voj voog tsim tsim
Paub meej txog qhov yuav tsum tau ua pov thawj qib xeem
Paub meej cov qauv txheej, txoj kab uas hla, thiab cov khoom siv
Paub meej tias tus qauv ntev, ntim, thiab lub sijhawm ua haujlwm
G.657 kev yuav khoom yuav tsum tsis txhob txo qis rau ib qho dabtsi yog khoov - vojvoog parameter. Lwm cov yam ntxwv ntawm fiber ntau, suav nrog hom kab kab, txoj kab uas hla ntawm cladding, concentricity, cutoff wavelength, macrobending poob, cov khoom siv, refractive index profile, thiab dispersion, kuj yuav tsum tau kuaj xyuas cov kev qhia tshwj xeeb.
7. Supply Stability kuj yog ib feem ntawm kev yuav khoom
Rau cov haujlwm loj FTTH, thawj cov lus hais tsis yog tib yam cuam tshuam rau kev ua tiav qhov project. Rov ua dua -kev txiav txim kom sib xws, cov khoom muaj nyob hauv, thiab kev xa khoom tuaj yeem ua qhov tseem ceeb sib npaug thaum qhov project txav mus rau hauv ntim xa tawm.
Rau cov neeg cog lus, cable manufacturers, thiab cov khoom siv network, tus neeg muag khoom yuav tsum muaj peev xwm teb ntau dua:
"Koj tus nqi yog dab tsi?"
"Puas muaj Tshuag npaum li cas?"
"Koj lub sij hawm ua tus qauv yog dab tsi?"
"Koj puas tuaj yeem tuav cov lus qhia tib yam rau kev xaj rov qab?"
"Koj puas tuaj yeem muab cov kev qhia tshwj xeeb fiber ntau?"
