Ftth (Fiber rau hauv tsev)
Tam sim no yog 'Top -}}} cov tshuaj rau tus neeg siv khoom siv hauv tsev, thiab tom qab ntawd faib cov network cable lossis wifi rau cov khoom siv hauv tsev. Lub feature yog tias bandwidth yog kiag li tau muab cia; Piv txwv li, 1000m Broadband yog siv ib leeg los ntawm cov neeg siv, tsis muaj kev cuam tshuam los ntawm cov neeg nyob sib ze 'kev siv internet, muab qhov zoo tshaj plaws thiab ruaj khov.
Cov ntsiab lus zoo
1. Cov bandwidth tshwj xeeb, tsis muaj lub ncov- lub sijhawm lag
2. Kev kub siab ntev (txhawb nqa 100m-1000m)
3. Lub zog ruaj khov, tsawg dua cuam tshuam los ntawm kev cuam tshuam sab nraud
Kev xaiv daws: ib gpon - Raws cov tshuaj ftth tau saws. Splitters tau xa mus rau hauv cov khoom siv hauv zej zog, nrog 1 × 32 tsev neeg thiab muab 1000Mbps bandwidth ib tus neeg siv.
Kev ua tiav cov txiaj ntsig: ntsuas download tau nrawm dua li nyob hauv 17db, uas tsis muaj kev sib tw nyob deb ntawm 20km thiab sib tham yav tom ntej 50g pon nce ntxiv.
Piv txwv zoo: piv rau FTTB nrog sib koom bandwidth, ua rau nws tsim nyog tshwj xeeb yog tsim nyog rau high {bandwidth li VR.
FTTR (fiber ntau rau hauv chav)
Nws tuaj yeem suav tias yog "hloov tshiab" ntawm FTTH, hais txog cov teeb liab teeb meem hauv cov chaw loj. Piv txwv li, hauv cov villas lossis cov chav tsev loj, ib qho Router Wifi yuav muaj thaj chaw tuag. Los ntawm txuas txhua chav nrog fiber ntau thiab tso ib sub- router hauv txhua chav, koj tuaj yeem ua tiav high} Kev pab cuam cuam tshuam rau lub tsev. Cov tub ntxhais yog kev sib xyaw ua ke ntawm "fiber ntau thiab wifi6," uas ua kom muaj tseeb} deb kis yam tsis muaj kev cuam tshuam thaum muab tag nrho} ceev wifi hauv txhua chav.
Cov ntsiab lus zoo
1. Tag nrho - house hous wifi uas tsis muaj qhov chaw tuag, tag nrho ceev hauv txhua chav
2. Txhawb nqa ntau yam khoom siv ib txhij (20 pab kiag li yam tsis muaj lag luam)
3. Fiber optic kis tsis muaj qhov ua kom tsis muaj kev cuam tshuam, ntev-} huab cua kev pov hwm
Kev xaiv daws: FTTR kev xaiv raws li OLT kho qhov muag kho kho kho qhov muag, nqa peb tes hauj lwm dhau ib fiber ntau.
Kev Siv Ua Ntej: {- pa nqa khoom siv lub sijhawm sib cuam tshuam kom tsis pub dhau 30ms, 4K video sab laj kev sib tham<5ms.- Operation and maintenance costs reduced by 90%, annual fault handling instances dropped from 48 to 3.
Comparative Advantages: Compared with traditional cabling, the multi-functional single-fiber feature of FTTR greatly simplifies the hotel network architecture and improves management efficiency.
Fttb (fiber ntau rau lub tsev)
Nws yog qhov sib xws 'kev tswj hwm kev daws teeb meem, qhov twg lub tsev muaj fiber ntau ntxiv mus cuag txhua tsev neeg siv cov cuab yeej siv network (xws li Cat5E). Lub drawback tau qhia bandwidth; Piv txwv li, 100 tsev neeg nyob rau hauv lub tsev muab 10g bandwidth, yog li internet ceev yuav qeeb qeeb thaum lub sij hawm peak (7}} 10 teev). Txawm li cas los xij, tus nqi tsim qauv yog tsawg, ua rau nws haum rau cov nyiaj loj-teev.
Cov ntsiab lus zoo
1. Cov nqi siv qis thiab siv dav dav
2. Tsis xav tau hauv -} Cov hlau hauv tsev, yooj yim rau nruab
Kev xaiv kev xaiv: FTB LAN
Kev Ua Tau Zoo: Ib Leeg - Tus Neeg Siv Cov Neeg Siv Cov Khoom Uas Cov Nyiaj Txiag uas twb muaj lawm, ua tiav cov kev hloov pauv ntawm tag nrho lub zej zog hauv 2 lub lis piam.
Piv txwv zoo: Hauv kev kho cov zej zog loj, FTB yog ntau dua tus nqi -}-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Cov khoom siv nyiaj tsawg tab sis xav tau yooj yim cov khoom siv nrawm.
FTTO (Fiber rau Chaw Haujlwm)
Tshwj xeeb tsim qauv rau cov tuam txhab koom tes, cov kab ke muaj hluav taws xob muaj fiber ntau yog txuas nrog txhua lub chaw ua haujlwm lossis cov haujlwm zoo li cov servers thiab luam tawm. Qhov kom zoo dua yog tias nws txhawb cov neeg siab ua tib zoo li, yog li ntau cov neeg tuaj yeem koom nrog hauv cov ntaub ntawv video lossis hloov cov ntaub ntawv loj ib txhij tsis muaj lag. Tsis tas li ntawd, cov tuam txhab nws lub chaw haujlwm tuaj yeem tswj tau yooj yim dua cov network rau txhua txoj haujlwm, muaj kev ruaj ntseg ntau dua.
Cov ntsiab lus zoo
1. Txhawb cov siab siab (dhau ib puas tus neeg ua haujlwm tsis muaj kev lag luam)
2. Network Kev Ruaj Ntseg yog tswj tau, ua rau nws yooj yim rau kev lag luam nws tswj hwm
3. Muaj peev xwm txuas ncaj qha rau cov servers, soj ntsuam cov khoom siv, thiab lwm yam khoom siv
Kev xaiv daws: Softel Me Me Optical FTTO daws, siv xgs - pa nyem rau txuas ncaj qha txuas 256 Optal aph thiab converged lub rooj vag.
Kev siv cov txiaj ntsig: {- cov nqi sib txuas lus txo los ntawm 40%; Kev rho tawm VLAN ua haujlwm ruaj ntseg sib cais ntawm cov rhiav dual network
Piv sib piv cov txiaj ntsig: piv rau FTB tau sib koom optic fiber ntau yog qhov tsim nyog dua rau kev lag luam hauv cov nqe lus ntawm kev ruaj khov thiab kev nyab xeeb.
