 Yintoni ukusasazwa kwe-cascade FTTH zizihlanganisi zodidi oluqinileyo?

Ukusasazwa kweCascade FTTH: Umboniso oMfutshane weFayibha kwiKhaya (FTTH) uthungelwano luyimfuneko ekuboneleleni ngesantya esiphezulu sokufikelela kwi-intanethi ngokuthe ngqo kwindawo yokuhlala kunye neyoshishino. Uyilo lwenethiwekhi ye-FTTH ichaphazela kakhulu ukusebenza kwayo, iindleko, kunye nobukhulu. Esinye isigqibo esibalulekileyo soyilo sibandakanya ukubekwa kwe-optical splitters, emisela ukuba kuphi na kwinethiwekhi i-fiber yahlulwe.

I-Centralised vs. I-Cascaded Architectures- Indlela Ephakathi:

1. Kwi-centralized approach, i-single-stage splitter (ngokuqhelekileyo i-1x32 splitter) ifakwe kwindawo ephakathi (njenge-fiber distribution hub okanye i-FDH).
2. I-hub inokufumaneka naphi na kwinethiwekhi.
3. I-1x32 i-splitter idibanisa ngokuthe ngqo kwi-GPON (i-Gigabit Passive Optical Network) i-Optical Line Terminal (OLT) kwiofisi ephakathi.
4. Ukusuka kwi-splitter, ii-fibers ze-32 zihanjiswa kumakhaya abathengi ngabanye, apho badibanisa kwi-Optical Network Terminals (ONTs).
5. Olu lwakhiwo ludibanisa izibuko elinye le-OLT kwii-ONT ezingama-32.

Indlela yeCascaded:

1. Kwindlela ye-cascade, i-multi-stage splitters (efana ne-1x4 okanye i-1x8 i-splitters) isetyenziswe kwi-topology yomthi kunye nesebe.
2. Ngokomzekelo, i-1x4 i-splitter inokuhlala kwindawo evaliweyo yeplanti kwaye idibanise ngqo kwi-OLT port.
3. Nganye kwiintsinga ezine ezishiya le nqanaba lokuqhekeza i-1 ihanjiswe kwi-terminal yokufikelela kwizindlu ze-1x8 isigaba se-2 sokuqhekeza.
4. Kule meko, iifiber ezingama-32 zizonke (4x8) zifikelela kumakhaya angama-32.
5. Kunokwenzeka ukuba ube nezigaba ezingaphezulu kwezibini zokwahlula kwi-cascaded system, enemilinganiselo eyahluka-hlukeneyo yokwahlula ngokubanzi (umz., 1x16, 1x32, 1x64).

Izinto ezizuzwayo kunye neNgqwalaselo- Indlela ebekwe kwindawo esembindini:

1. IiPros:

• Ubulula: Amanqanaba ambalwa okuqhekeza enza lula uyilo lwenethiwekhi.

• Uqhagamshelo oluthe ngqo: Izibuko le-OLT elinye liqhagamshela kwii-ONT ezininzi.

2. Ububi:

• Iimfuno zeFayibha: Ifuna ifayibha ngakumbi ngenxa yoqhagamshelo oluthe ngqo.

• Iindleko: Iindleko eziphezulu zokusasaza.

• Ukwandiswa: Ukubaleka kancinci ngaphaya kwabathengi abangama-32.

-Indlela eCascaded:

1. IiPros:

• Ukusebenza kakuhle kweFayibha: Ifuna ifayibha encinci ngenxa ye-branching.

• Ukusebenza kakuhle kweendleko: Iindleko ezisezantsi zokusasazwa.

• Ukwandiswa: Ukwandiswa ngokulula kubathengi abaninzi.

2. Ububi:

• Ukuntsokotha: Izigaba zokucalula ezininzi zongeza ubunzima.

• Ilahleko yomqondiso: Inqanaba ngalinye lokucalula lizisa ilahleko eyongezelelweyo.

Iziqhagamshelo zoNxibelelwano lwe-FTTH-Iziqhagamshelo eziqinileyo zidlala indima ebalulekileyo kukusasazwa kwe-FTTH:

1. Baphelisa imfuno yokudibanisa, ukwenza lula ukufakela.
2. Banciphisa izakhono zobugcisa ezifunwa ngabasebenzi.
3. Bakhawulezisa kwaye balungelelanise ukuthunyelwa, ukuhlangabezana nemfuno yothungelwano oluguquguqukayo noluthembekileyo.
