ANU UA HAUJ LWM UA HAUJ LWM? Kev nkag siab fiber broadband sib txuas rau koj lub tsev
Koj puas tau xav tias muaj fiber ntau-optic fiber ntau hauv is taws nem hauv koj lub tsev pabcuam (ISP) rau koj lub tsev? Lub ntsiab lus tseem ceeb ua rau kev sib txuas no yog tusChav tsev kho kho kho kho qhov muag (ONU), feem ntau yog hu ua "fiber modem ." Hauv tsab xov xwm no, peb yuav tshawb txog fiber ntau broadband rau hauv koj lub tsev .
1. Yuav ua li cas Thiaj Fiber Broadband mus txog koj lub tsev?
Fiber optic Broadband tsis magically tshwm sim hauv koj lub tsev - txoj hauv kev ua raws txoj kev ua tib zoo ua tiav:
- ISP Core Network: Cov ntaub ntawv keeb kwm los ntawm ISP's Central Data Center .
- OLT (Optical LINE Terminal): Nyob hauv kev sib pauv hauv nroog lossis txoj kev sib pauv, lub ord hloov hluav taws xob rau hauv cov cim kho qhov muag rau hauv kev tawm dag zog {}}
- Khoteci Splitter: Lub cuab yeej passive uas faib ib fiber ntau rau hauv ntau cov strands, pabcuam ntau tsev neeg .
- Cov Cuab Yeej Tso Tseg Cable: Ib qho nyias nyias, hloov tau fiber ntau fiber ntau khiav mus rau hauv koj lub tsev, feem ntau los ntawm kev nkag mus rau hauv phab ntsa {}}
- Onu (optical network chav): Cov cuab yeej uas hloov teeb pom kev rau hauv kev siv eternet / Wi-nkaus rau koj cov khoom .
2.} Ua haujlwm li cas?
Lub ONU ua raws li tus choj nruab nrab ntawm lub khoos phis tawm ntawm lub network thiab koj lub tsev li {}}}}}}} kev ua haujlwm ntawm nws txoj haujlwm:
(1) Txais ntawm cov paib
Cov fiber ntau txuas rau ONU'sPon chaw nres nkoj Pon(feem ntau sc / apc connector) .
Lub onu tau txaisCov Cim Tawm(1490 nm wavelength) Nqa cov ntaub ntawv hauv internet los ntawm olt .
(2) hloov dua siab tshiab
Lub Onting's Edik Kho Kom Zoo Hloov Pulses rau hauv cov cim hluav taws xob .
Cov txheej txheem tsim tawm cov ntaub ntawv rau cov ntaub ntawv rau hauv cov qauv eternet thav ntawv (IP pob) .
(3) Cov ntaub ntawv xa tawm
Kev Kawm Txoj Kev (Sib Koom Tes): Muaj ntau onus suav nrog ib router, muab Wi-nkaus thiab Lan chaw nres nkoj rau cov cuab yeej txuas ncaj qha {}}
Choj hom (yooj yim onu): Ua tib yam nkaus li cov media converter, xav tau ib sab sab nraud rau pppoe authentication {}}
(4) uploading cov ntaub ntawv (ntws los)
Thaum koj upload cov ntaub ntawv lossis video hu, lub onu hloov hluav taws xob cov cim hluav taws xob rov qab mus rau hauvnce cov paib(1310 nm) rau kis tus olt .

Kauj ruam 1: Fiberation Kev Tso Cai
Tus kws tshaj lij teeb tsa aTso cov xaim xaimlos ntawm qhov ze tshaj tawm (E {. g ., xov tooj ncej) .
Cov fiber ntau tawg lossis txuas nrog ntawm kev sib txuas nrawm (PLC) txiav .
Kauj ruam 2: Onu ua kom
Cov fiber tau txuas mus rau hauv ONU lub pon chaw nres nkoj .
ONU tseeb nrog OLT siv ALober (lub cim ID)lossis tus lej lej (ua ntej-teeb tsa los ntawm ISP) .
Thaum sau npe, tus OLT muab tus IP address, ua kom muaj kev siv internet nkag rau .
Kauj ruam 3: Txuas koj cov khoom siv
Wired: Txuas ib lub PC, Router, lossis Smart TV rau ONU ETHNET (LAN) PORTS .
Wireless: Yog hais tias ONU tau ua tiav lawm hauv Wi-nkaus, tsuas txuas koj lub smartphone / laptop .
{{04. Cov thev naus laus zis tseem ceeb nyob tom qab
Pon (Passive Optical Network)
Gon (gigabit pon): 2 {{. 5 Gbps Download / 1.25 GBPS Upload.
Epon (Ethernet Pon): 1 Gbps symmetric ceev .
XGS-PON (10G PON): Tom ntej-gen txuj kev muab 10 gbps ceev .
Fiber ntau hom
Ib-hom fiber ntau (smf): Kev deb-deb, qis attenuation (siv hauv ftth) .
Khoov-insensitive fiber ntau (g.657): Txo cov paib teeb meem poob hauv kev teeb tsa hauv tsev nruj .
