SFU thiab HGU yog cov cuab yeej tseem ceeb hauv kev sib txuas lus fiber ntau ntawm kev sib txuas lus fiber ntau thiab kev siv network, feem ntau siv rau kev nkag mus hauv tsev lossis cov kev lag luam me me. Nrog rau Fiber ntau Optic Broadband, HGU tau dhau los ua cov ntsiab lus vim nws txoj haujlwm thoob plaws, thaum SFU tau txo qis rau txoj haujlwm theem nrab.
SFU (ib tsev neeg nyob ib leeg)
Zaj piav
SFU yog txheej 2 kho qhov muag network davhlau ya nyob twg (ONT) hauv fiber ntau rau lub tsev (FTH) cov kev pabcuam fiber ntau, cov kev pabcuam fiber ntau rau cov neeg siv neeg hauv tsev neeg. Nws yog zoo li ib qho me me- chaw nres nkoj hloov thiab tsuas yog txhawb kev hloov kho tshiab ntawm kev hloov pauv hloov kho tshiab thiab cov ntaub ntawv hla kev ua haujlwm.
Yam ua hauj lwm
Cov teeb liab kho dua tshiab hloov dua siab tshiab: hloov kho qhov muag pom tau hloov dua tshiab kis tau los ntawm fiber ntau rau hauv cov khoom siv hluav taws xob.
Txheej 2 Cov Ntaub Ntawv Passthrough: txuas cov neeg siv cov 'routers lossis khoos phis tawj ntawm Ethernet Ports kom ua tiav cov ntaub ntawv xa khoom (choj hom).
Kev txhawb nqa Interface yooj yim: Feem ntau nruab nrog 1-4 etherpet xov tooj cuam tshuam (lauj kaub), thiab qee tus qauv txhawb nqa TV (CATV) cuam tshuam.
HGU (Tsev Rooj vag Tsev)
Zaj piav
Hgu yog peb {{- txheej txheej txheem kho qhov muag, thiab txhua yam kev ua haujlwm zoo li cov cuab yeej tseem ceeb ntawm lub tsev network.
Yam ua hauj lwm
Cov teeb liab kho qhov muag hloov dua siab tshiab: zoo ib yam li SFU, nws converts kho qhov muag rau hluav taws xob. Kev coj ua thiab Nat kev ua haujlwm: Txhawb nqa dynamas ip prinisition (xws li PPPoe Dialing) thiab muab cov nyiaj IPS ntiag tug mus txog hauv tsev tshuab.
Wi {-} {-}}}}}}}} fi 5/6), txhawb ib qho kev sib txuas ntawm ntau cov khoom siv. Cov Txheej Txheem Kev Tswj Xyuas Tshaj: Txhawb cov chaw taws teeb teeb, Firewall, QOS tsheb tswj, thiab lwm yam.
Multi - Kev Pabcuam Kev Sib Tham: Muab cov kev pabcuam xws li lub suab (VOIP), IPB, thiab USB kev sib qhia.
