Cov lus teb ceev
Kev txhim kho FTTH txhim khu kev qha yog ua hauv plaub ODN txheej:feeder, kev faib tawm, poobthiabsubscriber. Cov txheej feeder nqa G.652D sab nraum zoov cable los ntawm sab OLT mus rau lub txee, splice kaw lossis thawj splitter. Cov txheej txheem faib cov txheej txheem faib cov fibers mus rau hauv txoj kev thawv los yog lub tsev cov ntsiab lus nkag. Cov txheej txheem poob siv G.657A2 khoov- tsis pom kev cable los ntawm FDB lossis NAP mus rau thaj chaw. Cov txheej txheem ua tiav qhov txuas nrog lub thawv txiav, SC / APC pigtail, phab ntsa qhov hluav taws xob thiab ONT thaj qaum.
Rau kev npaj, kho qhov project raws li ib theem ntawm engineering rooj vag: txoj kev soj ntsuam, pej xeem npaj, feeder installation, splitter installation, tis lub thawv teeb, xa cable routing, cov neeg siv khoom txiav thiab txais kev kuaj. Tsis pom zoo qhov txuas nkaus xwb vim tias ONT tuaj online. Kev lees txais yuav tsum suav nrog kev tshuaj xyuas cov khoom sib txuas, kev ntsuas kev ntsuas OLTS bidirectional, cov ntaub ntawv OTDR thiab cov ntaub ntawv kho qhov muag.
Siv nplooj ntawv no ua ib daim ntawv teev kev yuav khoom thiab xa mus. Qhov tseem ceeb xws li splitter poob, connector poob, IP ntsuam xyuas thiab cable tensile load yuav tsum tseem raug lees paub tiv thaiv cov ntaub ntawv cov khoom tiag, cov cai hauv zos thiab cov cai txais neeg teb xov tooj.
Cov lus qhia no tau raug tshuaj xyuas los ntawm Glory Optical's ODN khoom engineering thiab fiber optic QC tshuaj xyuas pawg. Kev tshuaj xyuas tau tsom mus rau cov qauv tsis zoo ODN BOM, kev xaiv khoom noj khoom haus thiab tso cov kab hluav taws xob, PLC splitter kev npaj, splice kaw sealing, connector huv si thiab kev lees txais kev xeem logic. Nws yog raws li Glory Optical khoom datasheet tshuaj xyuas, FTTH RFQ / BOM kev txhawb nqa thiab Hoobkas QC xyaum; nws tsis hloov cov cai lees txais tus neeg teb xov tooj hauv zos lossis cov ntawv pov thawj tsim kev tshuaj xyuas qhov project.
FTTH Cov Khoom Siv: BOM los ntawm ODN Txheej
Qhov tseeb FTTH BOM yuav tsum tau teeb tsa los ntawm ODN txheej, tsis yog los ntawm cov npe khoom lag luam. Qhov no ua rau nws yooj yim dua rau kev yuav khoom, kev teeb tsa thiab QA pab pawg los xyuas seb puas yog txhua ntu cable, passive node thiab xeem kauj ruam muaj qhov zoo.

Ib zaug - theem vs ob - theem sib cais
Hauv ib qho -theem tsim, ib qho splitter, feem ntau 1:32, ua haujlwm rau cov neeg siv khoom ncaj qha los ntawm lub txee lossis qhov chaw taws teeb. Qhov no ua kom yooj yim cov ntaub ntawv tab sis concentrates cais poob ntawm ib qho chaw. Hauv ob -theem tsim, xws li 1: 8 ua raws li 1: 4, kev sib cais yog muab faib thoob plaws lub hauv paus ntawm thiab ib txoj kev lossis lub tsev- theem FDB. Ob- theem tsim qauv tuaj yeem ua kom yooj yim rau cov neeg koom nrog pawg thiab nthuav dav, tab sis lawv ntxiv ntau lub cev rau cov ntaub ntawv thiab sim. Qhov kev xaiv raug yog kev txiav txim siab txog nyiaj txiag thiab kev ua haujlwm, tsis yog kev xaiv khoom xwb.

Tsis txhob lees txais tsuas yog nyob ONT nyeem ntawv; nws tsis muab lub hauv paus txhim khu kev qha rau kev sib cais txhaum yav tom ntej.
Q: Dab tsi yog qhov txawv ntawm G.657A2 thiab G.652D fiber ntau hauv FTTH?
A: G.652D yog tus qauv ib zaug - hom fiber ntau siv hauv feeder thiab tis cables uas khoov tau tswj. G.657A2 yog khoov-sensitive ib leeg- hom fiber ntau npaj rau kev nkag, poob thiab sab hauv txoj hauv kev uas muaj qhov khoov nruj dua. Hauv FTTH tsim, ib txoj hauv kev zoo tshaj plaws yog siv G.652D nyob rau hauv lub feeder thiab tis network, ces siv G.657A2 los ntawm FDB los yog txiav tawm taw tes rau cov neeg siv khoom.
Q: Kuv yuav xaiv lub thawv fiber ntau rau FTTH li cas?
A: Xaiv lub thawv txiav fiber ntau los ntawm cov chaw nres nkoj suav, splice peev, hom adapter, mounting txoj kev thiab ib puag ncig. Ib lub tsev ib leeg yuav xav tau 1-2 chaw nres nkoj SC/APC lub thawv, thaum txoj kev hauv tsev, ncej lossis MDU nkag nkag yuav xav tau 4-12 chaw nres nkoj lossis ntau dua. Cov thawv sab nraum zoov xav tau kev tiv thaiv tus IP tsim nyog, kev tiv thaiv kab mob kev tiv thaiv, splice tais qhov chaw thiab khoov - vojvoog tswj. Hauv qab -qib lossis dej nyab- cov chaw nyob ib puag ncig feem ntau xav tau qib kev sib khi siab dua li cov chaw thaiv phab ntsa.

Cov kab lus saum toj no piav qhia txog cov txheej txheem engineering. Cov khoom xaiv hauv qab no yog txhob txwm ua pawg los ntawm txheej yog li pawg neeg yuav khoom tuaj yeem hloov tus qauv tsim rau hauv RFQ lossis BOM yam tsis hloov cov lus qhia rau hauv cov khoom catalogue.
Sab nraum zoov Fiber Cable + Splice Kaw
Siv sab nraum zoov feeder cable thiab kaw splice kaw rau qaum ODN txoj kev. Paub meej tias fiber ntau suav, tensile ntsuam xyuas, kaw lub peev xwm thiab IP ntsuas ua ntej kev yuav khoom.
Saib splice kawFDB / NAP Box + PLC Splitter
Siv cov thawv ntim fiber ntau thiab PLC splitters los tswj cov neeg siv khoom. Paub meej qhov sib faib piv, hom adapter, suav chaw nres nkoj thiab lub peev xwm seem.

Xaiv txoj kab ncaj nraim los yog puag ncig xaim raws li dav hlau, kav dej lossis phab ntsa- nkag mus. Ua ke nws nrog lub thawv txiav tawm uas txhawb nqa txoj kev yooj yim thiab khoov tswj.
Saib FTTH poob cablePigtail + Phab ntsa qhov hluav taws xob + Patch Cord
Siv SC/APC pigtails, sab hauv phab ntsa qhov hluav taws xob thiab luv patch cords kom tiav ONT- sab kev sib txuas. Khaws cov interfaces capped kom txog thaum kuaj xyuas thiab ua kom tiav.
