Isu takazvipira kupa zviri nyore, kuchengetedza nguva uye kuchengetedza mari imwe-kumira kutenga sevhisi yevatengiChina Olt uye Gpon Olt, Kana Yakagadzira, ichishandisa nzira huru yenyika yekushanda kwakavimbika, mutengo wakaderera wekutadza, wakakodzera kuJeddah vatengesi sarudzo.Bhizinesi redu.iri mukati memaguta akabudirira enyika, iyo webhusaiti traffic haina kunetsekana, yakasarudzika yenzvimbo uye mamiriro emari.Isu tinotevera "yakatarisana nevanhu, kugadzira zvine hungwaru, kufunga, kuita hungwaru" huzivi hwekambani.Yakasimba yemhando yepamusoro manejimendi, inonakidza sevhisi, inodhura mutengo muJeddah ndiko kumira kwedu kwakatenderedza nzvimbo yevakwikwidzi.Kana zvichidikanwa, tinokugamuchirai kuti tibatane nesu newebhu peji yedu kana kubvunzana parunhare, isu tichafara kukushandirai.
LM241TW4, dual-mode ONU/ONT, ndeimwe yeXPON optical network units, inotsigira GPON uye EPON nzira mbiri dzekuzvigadzirisa.Inoshandiswa kuFTTH/FTTO, Iyo LM241TW4 inogona kubatanidza mawaya mabasa anoenderana ne802.11 a/b/g/n hunyanzvi zviyero.Iyo zvakare inotsigira 2.4GHz isina waya chiratidzo.Inogona kupa vashandisi vane hunyanzvi hwekufambisa data kuchengetedza kuchengetedza.Uye ipa inodhura-inoshanda sevhisi yeTV kuburikidza ne1 CATV port.
Iyo 4-port XPON ONT inobvumira vashandisi kuwana yakakwirira-kumhanya Internet yekubatanidza XPON port, iyo inogoverwa neGigabit Ethernet port.Kumusoro 1.25Gbps, kudzika 2.5/1.25Gbps, kureba kwekufambisa kusvika ku20Km.Nekumhanya kunosvika 300Mbps, LM240TUW5 inoshandisa antenna yekunze omnidirectional kukwirisa waya isina waya uye kunzwa, kuitira kuti iwe ugone kugamuchira masaini masaini chero kupi zvako mumba mako kana muhofisi uye iwe unogona zvakare kubatana neTV, iyo inogona kupfumisa hupenyu hwako.
Q1: Ndeupi musiyano uripo pakati peEPON GPON OLT neXGSPON OLT?
Musiyano mukuru ndewekuti XGSPON OLT inotsigira GPON/XGPON/XGSPON, Inokurumidza Kumhanya.
Q2: Mangani maONT anogona kubatanidza EPON yako kana GPON OLT kune
A: Izvo zvinoenderana nehuwandu hwemadoko uye optical splitter ratio.Kune EPON OLT, 1 PON port inogona kubatana ne64 pcs ONTs yakanyanya.YeGPON OLT, 1 PON port inogona kubatana ne128 pcs ONTs yakanyanya.
Q3: Ndeipi yakakura yekufambisa chinhambwe chezvigadzirwa zvePON kune mutengi?
A: Yese iyo pon port's max transmission kureba ndeye 20KM.
Q4: Unogona here kuudza Ndeupi musiyano weONT & ONU?
A: Hapana mutsauko mune zvakakosha, ese ari maviri evashandisi 'midziyo.Iwe unogona zvakare kutaura kuti ONT chikamu cheONU.
Q5: Chii chinonzi FTTH/FTTO?
Chii chinonzi FTTH/FTTO?
Munyika yanhasi yedhijitari-centric, yakakwirira-kumhanya internet yekubatanidza haisisiri yeumbozha asi chinhu chinodiwa.Sezvo kudiwa kweinternet nekukurumidza uye kwakavimbika kuri kuramba kuchikura, makambani enharembozha anoenderera mberi nekuongorora matekinoroji ekusangana nezvinodiwa nevatengi.Gigabit Passive Optical Network (GPON) tekinoroji iri kushandura indasitiri yebroadband.Muchikamu chino, tichaongorora zvakanakira GPON, kunyanya kushandiswa kwayo kwe16-port, matatu-layer OLT uye FTTH optical terminals kuvandudza zvakanyanya network kushanda zvakanaka nekuita.
GPON ndeye fiber-optic network architecture inopa yakanyanya-kumhanya Internet, izwi, uye vhidhiyo masevhisi kune vanogara uye bhizinesi vashandisi.Iyo inoshandisa point-to-multipoint topology, ichishandisa passive optical splitters kugovera data kune akawanda vatengi panguva imwe chete.GPON inoshandisa Layer 2 yekufambisa nzira yekufambisa data, ichipa zvinokatyamadza bandwidth inosvika 2.5 Gbps pasi uye 1.25 Gbps kumusoro.
Mwongo weGPON network ndiyo optical line terminal (OLT).Iyo OLT's Layer 3 hunyanzvi inogonesa kugovera kwakanaka kwetiweki zviwanikwa uye nehungwaru packet routing.Iine OLT inotsigira Layer 3 kugona, vanopa telecom vanogona kuona yakagadziridzwa traffic, kuderedza kuungana, uye kuwedzera mashandiro etiweki.Pamusoro pezvo, Layer 3 OLTs inopa epamberi kuchengetedza maficha akadai seIP kusefa uye firewall kuchengetedza kuchengetedza network kubva kune zvinogona kutyisidzira.
Fiber-to-the-home (FTTH) modhi inogoneswa neGPON tekinoroji uye inoshandisa mafiber optic terminals kupa yakananga faibha kubatana kudzimba dzega kana mabhizinesi.Yakashongedzerwa neakawanda 16 madoko, aya madiki, madiki maturusi anogona kubata zviri nyore kugovera uye kumisa masaini emaziso, kuve nechokwadi chekubatanidza isina musono mukati metiweki.FTTH optical terminals inoshanda sebhiriji pakati peoptical fiber neEthernet, ichigonesa kukurumidza-kumhanyisa data kutapurirana uye kuvimbika kwenharembozha masevhisi.
GPON ine mabhenefiti akawanda kana yasanganiswa nematatu-layer OLT uye FTTH optical terminals.Chekutanga, inopa isingaenzaniswi bandwidth kugona kusangana nevatengi 'vari kukura data zvinodiwa.Iyo tekinoroji zvakare inoderedza kushandiswa kwemagetsi, ichiita kuti ive sarudzo ine hushamwari.Pamusoro pezvo, GPON's scalability inogonesa inodhura-inoshanda network kuwedzera uye ramangwana-uchapupu zvivakwa.
Muchidimbu, kusanganiswa kwe16-port, matatu-layer OLT uye FTTH optical terminal yakashandura zvachose indasitiri yebroadband.Tekinoroji yeGPON inounza hupamhi hwekumhanya, manejimendi ezviwanikwa uye kuchengetedzeka kwakawedzera kune nharembozha.Nekutora GPON, vanopa masevhisi vanogona kupa vatengi vavo Internet isina musono, izwi nemavhidhiyo masevhisi anosangana nekupfuura zvavanotarisira munguva ino yedhijitari.
