Ho Fuputsa Liphapano Har'a ONU, ONT, SFU, le HGU.

Ha ho tluoa tabeng ea lisebelisoa tsa lehlakoreng la basebelisi ho fihlella fiber ea Broadband, hangata re bona mantsoe a Senyesemane a kang ONU, ONT, SFU, le HGU.Mantsoe aa a bolela'ng?Phapano ke efe?

1. Li-ONU le li-ONT

Mefuta ea mantlha ea ts'ebeliso ea phihlello ea fiber ea Broadband optical e kenyelletsa: FTTH, FTTO, le FTTB, 'me mefuta ea lisebelisoa tse lehlakoreng la mosebelisi e fapane tlasa mefuta e fapaneng ea ts'ebeliso.Thepa e lehlakoreng la mosebelisi ea FTTH le FTTO e sebelisoa ke mosebelisi a le mong, e bitsoang ONT (Optical network terminal, optical network terminal), mme lisebelisoa tsa lehlakoreng la mosebelisi tsa FTTB li arolelanoa ke basebelisi ba bangata, ba bitsoang ONU (Optical Network Unit, optical. yuniti ya marangrang).

Mosebelisi ea boletsoeng mona o bua ka mosebelisi ea lefelloang a le mong ke opareitara, eseng palo ea liteishene tse sebelisitsoeng.Ka mohlala, ONT ea FTTH hangata e arolelanoa ke li-terminals tse ngata lapeng, empa ho ka baloa mosebedisi a le mong feela.

2. Mefuta ea li-ONT

ONTke seo ka tlwaelo re se bitsang modem ya optical, e arotsweng ka SFU (Single Family Unit, single family user unit), HGU (Home Gateway Unit, home gateway unit) le SBU (Single Business Unit, single business user unit).

2.1.SFU

SFU ka kakaretso e na le likhokahano tsa Ethernet tse 1 ho isa ho tse 4, likhokahano tsa mohala tse 1 ho isa ho tse 2, 'me mefuta e meng le eona e na le likhokahano tsa cable tsa TV.SFU ha e na ts'ebetso ea heke ea lapeng, mme ke terminal feela e hokahantsoeng le boema-kepe ba Ethernet e ka letsetsa ho fihlella Marang-rang, mme ts'ebetso ea taolo e hole e fokola.Modem ea optical e sebelisitsoeng mothating oa pele oa FTTH ke ea SFU, e sebelisoang seoelo hona joale.

2.2.Li-HGUs

Li-modem tsa optical tse nang le basebelisi ba FTTH tse butsoeng lilemong tsa morao tjena ke HGU kaofela.Ha e bapisoa le SFU, HGU e na le melemo e latelang:

(1) HGU ke sesebelisoa sa heke, se loketseng marang-rang a lapeng;ha SFU e le sesebelisoa sa phetisetso se pepeneneng, se se nang bokhoni ba heke, 'me ka kakaretso se hloka tšebelisano-'moho ea lisebelisoa tsa heke joalo ka li-routers tsa lapeng marang-rang a lapeng.

(2) HGU e tšehetsa mokhoa oa ho tsamaisa 'me e na le ts'ebetso ea NAT, e leng sesebelisoa sa layer-3;ha mofuta oa SFU o ts'ehetsa mokhoa oa borokho oa layer-2 feela, o lekanang le switch ea layer-2.

(3) HGU e ka kenya ts'ebetsong ts'ebeliso ea eona ea Broadband dial-up, mme likhomphutha tse hokahantsoeng le liteishene tsa mehala li ka kena inthaneteng ka kotloloho ntle le ho daela;ha SFU e tlameha ho letsetsoa ke komporo ea mosebelisi kapa mohala oa thekeng kapa ka router ea lapeng.

(4) HGU e bonolo bakeng sa tsamaiso e kholo ea ts'ebetso le tlhokomelo.

HGU hangata e tla le WiFi mme e na le kou ea USB.

2.3.Li-SBUs

SBU e sebelisoa haholo-holo bakeng sa phihlello ea basebelisi ba FTTO, 'me ka kakaretso e na le sebopeho sa Ethernet,' me mefuta e meng e na le sebopeho sa E1, sehokelo sa mohala, kapa ts'ebetso ea wifi.Ha e bapisoa le SFU le HGU, SBU e na le ts'ebetso e ntle ea ts'ireletso ea motlakase le botsitso bo phahameng, hape e sebelisoa hangata liketsahalong tsa kantle tse kang ho lekola livideo.

3. Mofuta oa ONU

ONU e arotsoe ka MDU (Multi-Dwelling Unit, multi-resident unit) le MTU (Multi-Tenant Unit, multi-rent unit).

MDU e sebelisoa haholo bakeng sa phihlello ea basebelisi ba bangata ba bolulo tlas'a mofuta oa kopo ea FTTB, 'me ka kakaretso bonyane e na le likhokahano tse 4 tsa mahlakore a basebelisi, hangata li na le likhokahano tsa 8, 16, 24 FE kapa FE+POTS (mohala o tsitsitseng).

MTU e sebelisoa haholo bakeng sa phihlello ea basebelisi ba likhoebo tse ngata kapa li-terminals tse ngata khoebong e le 'ngoe maemong a FTTB.Ntle le sebopeho sa Ethernet le sebopeho se tsitsitseng sa mohala, se ka boela sa ba le sebopeho sa E1;sebopeho le tšebetso ea MTU hangata ha li tšoane le tsa MDU.Phapang, empa ts'ebetso ea ts'ireletso ea motlakase e betere mme botsitso bo phahame.Ka ho ata ha FTTO, maemo a ts'ebeliso ea MTU a ntse a fokotseha.

4. Kakaretso

Phihlello ea fiber ea Broadband optical haholo e sebelisa theknoloji ea PON.Ha mofuta o itseng oa lisebelisoa tsa lehlakoreng la mosebelisi o sa khethollehe, lisebelisoa tsa lehlakoreng la mosebelisi tsa sistimi ea PON li ka bitsoa ka kakaretso e le ONU.

ONU, ONT, SFU, HGU…lisebelisoa tsena kaofela li hlalosa lisebelisoa tsa mahlakoreng a basebelisi bakeng sa phihlello ea Broadband ho tsoa mahlakoreng a fapaneng, mme kamano lipakeng tsa tsona e bonts'itsoe setšoantšong se ka tlase.
