Q1: Na nka beha letšoao le mohlala oa rona lihlahisoa tsa hau?

A: Ehlile, re tšehetsa OEM le ODM ho latela MOQ.

Q2: MOQ ea hau ea ONT le OLT ke efe?

Bakeng sa odara ea batch, ONT ke 2000 units, OLT ke 50 units.Linyeoe tse khethehileng, re ka buisana.

Q3: Na li-ONT/OLT tsa hau li ka tsamaellana le lihlahisoa tsa motho oa boraro?

K: E, li-ONT/OLT tsa rona li tsamaisana le lihlahisoa tsa batho ba boraro tlas'a melaoana e tloaelehileng.

Q4: Nako ea tiisetso ea hau e telele hakae?

A: 1 selemo.

SWITCH ke eng?

Phetoho e bolela "swicha" ke sesebelisoa sa marang-rang se sebelisetsoang ho fetisa matshwao a motlakase (optical).E ka fana ka tsela e ikhethang ea lets'oao la motlakase bakeng sa node efe kapa efe e 'meli ea marang-rang e fihlellang switch.Li-switch tse atileng haholo ke li-switch tsa Ethernet.Tse ling tse tloaelehileng ke li-switches tsa lentsoe tsa mohala, li-fiber switches, joalo-joalo. Lefats'eng la kajeno le potlakileng, le amanang le hyper-connected, likhoebo le mekhatlo e itšetlehile haholo ka marang-rang a bona ho tsamaisa data ka mokhoa o tsitsitseng le ka katleho.Ha tlhoko ea litharollo tse tsoetseng pele tsa marang-rang e ntse e hola, sehlahisoa se secha se fetotse tsela eo data e fetisoang ka eona - Li-switch tsa Layer 3.

Ha e le hantle, sesebelisoa sa Layer 3 se kopanya ts'ebetso ea sesebelisoa sa setso le likarolo tse tsoetseng pele le bokhoni bo fumanehang ho li-routers.Motsoako ona o matla o ntlafatsa ts'ebetso, o ntlafatsa ts'ireletso, 'me o eketsa ho feto-fetoha ha maemo ho laola sephethephethe sa marang-rang.

E 'ngoe ea melemo ea bohlokoa ea li-switches tsa Layer 3 ke bokhoni ba tsona ba ho tsamaisa data ka lebelo le phahameng, e leng se etsang hore e be tse loketseng mekhatlo e sebetsanang le sephethephethe se seholo sa marang-rang.Ka matla a ho fetisa a hahelletsoeng, e tsamaisa lipakete ka nepo moo e eang teng, e fokotsa latency le ho ntlafatsa ts'ebetso ea marang-rang.Sena se etsa hore e be khetho e ntle haholo bakeng sa mesebetsi e tebileng ea data e kang ho phallela video, cloud computing, le Voice over IP (VoIP) app.

Ntle le moo, li-switch tsa Layer 3 li sebelisa likarolo tse tsoetseng pele tsa ts'ireletso ho sireletsa data e hlokolosi le ho itšireletsa khahlanong le litlhaselo tse lonya.Ka bokhoni ba li-firewall tse hahelletsoeng, ba lekola le ho laola sephethephethe sa marang-rang ho netefatsa hore basebelisi ba lumelletsoeng ke bona feela ba ka fihlelang lisebelisoa tsa bohlokoa.Sena se thibela phihlello e sa lumelloeng mme se sireletsa botšepehi ba lisebelisoa tsa marang-rang.

Ntho e 'ngoe e hlokomelehang ea li-switches tsa Layer 3 ke bokhoni ba bona ba ho theha marang-rang a sebaka sa libaka (VLANs), e leng ho nolofalletsang ho aroloa ha marang-rang le ho ntlafatsa tsamaiso ea sephethephethe.Ka ho arola marang-rang a le mong hore e be marang-rang a mangata a utloahalang, li-VLAN li thusa mekhatlo ho arola mafapha kapa lihlopha tse itseng tsa basebelisi, ho netefatsa hore ho fanoa ka katleho ea bandwidth le ho ntlafatsa ts'ebetso ea marang-rang ka kakaretso.

Ho feta moo, li-switch tsa Layer 3 li fana ka mesebetsi e felletseng ea taolo, e nolofalletsang batsamaisi ba marang-rang ho beha leihlo le ho laola sephethephethe sa marang-rang ka nepo.Ka mekhoa e hlakileng le e bonolo ea basebelisi, batsamaisi ba ka hlophisa le ho laola litlhophiso tse fapaneng tsa marang-rang, ho shebella metrics ea ts'ebetso, le ho rarolla mathata afe kapa afe a marang-rang a ka hlahang.Sena se nolofatsa ts'ebetso eohle ea tsamaiso ea marang-rang, ho boloka nako ea bohlokoa le lisebelisoa.

Qetellong, li-switches tsa Layer 3 li emela tsoelo-pele e kholo ho theknoloji ea marang-rang.Bokhoni ba eona ba ho kopanya mesebetsi ea switch le router, hammoho le bokhoni ba ho tsamaisa ka lebelo le holimo, likarolo tse tsoetseng pele tsa ts'ireletso, le likhetho tse felletseng tsa taolo, li e khetholla ho tharollo ea setso ea marang-rang.Hore na o khoebo e nyane, khoebo ea boholo bo bohareng, kapa mokhatlo o moholo, li-switches tsa Layer 3 ke tharollo e nepahetseng ea marang-rang ho fihlela litlhoko tsa hau tse fetohang.Eba le matla le katleho ea sesebelisoa sa Layer 3 'me u notlolle bokhoni ba 'nete ba marang-rang a hau.
