Q1: O ka mpolella ka nako ea hau ea tefo?
A: Bakeng sa disampole, 100% tefo esale pele.Bakeng sa odara e ngata, T / T, 30% tefo ea pele, 70% e setseng pele e romelloa.
Q2: Nako ea hau ea ho fana e joang?
A: 30-45days, haeba tloaelo ea hau e le ngata haholo, e tla nka nako e teletsana.
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.
Q5: Phapano ke efe pakeng tsa EPON GPON OLT le XGSPON OLT?
Phapang e kholo ke hore XGSPON OLT e tšehetsa GPON/XGPON/XGSPON, Lebelo le Lebelo.
Q6: Mekhoa e amohelehang ea ho lefa bakeng sa k'hamphani ea hau ke efe?
Bakeng sa sampole, 100% tefo esale pele.Bakeng sa taelo ea batch, T / T, 30% deposit, 70% ho leka-lekana pele ho pepa.
Q7: Na k'hamphani ea hau e na le lebitso la eona?
E, lebitso la k'hamphani ea rona ke Limee.A Layer 3 switch ke mofuta oa sesebelisoa sa marang-rang se sebetsang karolong ea marang-rang ea mohlala oa OSI.Sena se bolela hore e na le bokhoni ba ho etsa liqeto tsa ho tsamaisa tse ipapisitseng le liaterese tsa IP, joalo ka router.Li-switches tsa Layer 3 li sebelisoa hangata ho marang-rang a likhoebo ho hokahanya li-subnet tse fapaneng le ho etsa liqeto mabapi le hore na u ka fetisetsa sephethephethe hokae.
Joale, ha e le hantle switch ea Layer 3 ke eng, 'me e fapana joang le switch ea setso ea Layer 2?Sesebelisoa sa Layer 2 se sebetsa lealong la khokahano ea data ea mohlala oa OSI mme se etsa liqeto tsa ho fetisa ho ipapisitsoe le liaterese tsa MAC.Le ha e sebetsa hantle ho fetisa sephethephethe ka har'a subnet e le 'ngoe, ha e na bokhoni ba ho etsa liqeto tsa ho tsamaisa sephethephethe ho ea ho subnets tse fapaneng.Mona ke moo switch ea Layer 3 e kenang teng.
Sesebelisoa sa Layer 3 se kopanya ts'ebetso ea sesebelisoa sa setso sa Layer 2 le bokhoni ba ho tsamaisa router.E khona ho theha li-LAN tsa sebele (VLANs) le ho tsamaisa sephethephethe pakeng tsa tsona, hammoho le ho etsa liqeto mabapi le tsela e molemohali ea hore sephethephethe se tsamaee ka marang-rang.Sena se etsa hore e be sesebelisoa se matla sa ho laola le ho ntlafatsa sephethephethe sa marang-rang ho marang-rang a maholo, a rarahaneng.
E 'ngoe ea melemo ea bohlokoa ea ho sebelisa switch ea Layer 3 ke bokhoni ba eona ba ho ntlafatsa ts'ebetso ea marang-rang.Ka ho theola tse ling tsa mesebetsi ea ho tsamaisa ho tloha ho router ea mantlha ho ea ho Layer 3 switch, sephethephethe sa marang-rang se ka tsamaisoa ka mokhoa o atlehileng haholoanyane, se lebisang puisanong e potlakileng le e tšepahalang lipakeng tsa lisebelisoa tsa marang-rang.
Ka kakaretso, switch ea Layer 3 ke letlotlo la bohlokoa bakeng sa mekhatlo e nang le litlhoko tse rarahaneng tsa marang-rang.Bokhoni ba eona ba ho kopanya mesebetsi ea switch le router e etsa hore e be karolo ea bohlokoa bakeng sa ho laola le ho ntlafatsa sephethephethe sa marang-rang.Ha likhoebo li ntse li tsoela pele ho itšetleha ka litharollo tse matla le tse sebetsang tsa marang-rang, li-switches tsa Layer 3 li tla tsoelapele ho bapala karolo ea bohlokoa ho netefatsa hore data e tsamaea ka mokhoa o sa tsitsang le ka ts'epo ho marang-rang.
