Ubwihindurize bwa LIMEE Ikoranabuhanga rya GPON: Gucukumbura ibyiza bya Layeri 3 OLT na FTTH Optical Terminal

Twiyemeje gutanga serivisi zoroshye, zitwara igihe kandi zizigama amafaranga yo kugura serivisi imwe yo kugura abaguzi kubijyanye na tekinoroji ya GPON ya LIMEE: Gucukumbura ibyiza bya Layeri 3 OLT na FTTH Optical Terminal, Turakwishimiye rwose kuba mubice twe muriyi nzira yo gukora imishinga yubucuruzi ikungahaye kandi itanga umusaruro hamwe.
Twiyemeje gutanga serivisi yoroshye, izigama igihe kandi izigama amafaranga serivisi imwe yo kugura abaguzi kuriUbushinwa Olt na Gpon Olt, Iyo Yabyaye, ikoresha uburyo bukomeye bwisi kwisi kubikorwa byizewe, igiciro gito cyo gutsindwa, birakwiriye guhitamo abaguzi ba Jeddah.Uruganda rwacu.s biherereye mumijyi yubusabane bwigihugu, urujya n'urubuga ntiruhura cyane, imiterere yihariye yubukungu nubukungu.Dukurikirana "abantu-bishingiye ku bantu, gukora neza, kungurana ibitekerezo, gukora ibintu byiza" filozofiya ya sosiyete.Gucunga neza ubuziranenge, serivisi nziza, igiciro cyiza muri Jeddah nicyo gihagararo cyacu imbere yabanywanyi.Niba bikenewe, urakaza neza kugirango utumenyeshe kurupapuro rwurubuga cyangwa kugisha inama kuri terefone, tuzishimira kugukorera.

Ibiranga ibicuruzwa

LM241TW4, uburyo bubiri ONU / ONT, nimwe murwego rwa XPON optique ya netique, shyigikira GPON na EPON uburyo bubiri bwo kwimenyereza.Bikoreshwa kuri FTTH / FTTO, LM241TW4 irashobora guhuza imikorere idafite umugozi ihuye na 802.11 a / b / g / n ibipimo bya tekiniki.Ifasha kandi ibimenyetso bya 2.4GHz.Irashobora guha abakoresha uburyo bwiza bwo kohereza amakuru kurinda umutekano.Kandi utange serivise nziza ya TV ukoresheje icyambu 1 CATV.

Icyambu 4-XPON ONT yemerera abakoresha kugera kumurongo wihuta wa enterineti XPON, isangiwe nicyambu cya Gigabit Ethernet.Hejuru 1.25Gbps, kumanuka 2.5 / 1.25Gbps, intera yohereza kugeza kuri 20Km.Hamwe n'umuvuduko ugera kuri 300Mbps, LM240TUW5 ikoresha antenne yo hanze ikwirakwiza ibintu byose kugirango igabanye umurongo wa simsiz na sensibilité, kugirango ubashe kwakira ibimenyetso bidafite umugozi aho ariho hose murugo cyangwa mu biro kandi ushobora no guhuza na TV, ishobora guteza imbere ubuzima bwawe.

Ibibazo

Q1: Ni irihe tandukaniro riri hagati ya EPON GPON OLT na XGSPON OLT?

Itandukaniro rinini nuko XGSPON OLT ishyigikira GPON / XGPON / XGSPON, Umuvuduko Wihuse.

Q2: Nangahe ONT yawe EPON cyangwa GPON OLT ishobora guhuza

Igisubizo: Biterwa nibyambu byinshi hamwe na optique yo gutandukanya.Kuri EPON OLT, icyambu 1 PON kirashobora guhuza 64 pcs ONTs ntarengwa.Kuri GPON OLT, icyambu 1 PON kirashobora guhuza 128 pcs ONTs ntarengwa.

Q3: Nubuhe burebure bwohereza ibicuruzwa bya PON kubaguzi?

Igisubizo: Intera zose zoherejwe nicyambu cya 20KM.

Q4: Ntushobora kuvuga Itandukaniro rya ONT & ONU?

Igisubizo: Nta tandukaniro riri muri rusange, byombi ni ibikoresho byabakoresha.Urashobora kandi kuvuga ko ONT igizwe na ONU.

Q5: FTTH / FTTO ni iki?

FTTH / FTTO ni iki?

Muri iki gihe isi yibanda cyane kuri enterineti, umurongo wa interineti wihuta ntukiri mwiza kandi ni ngombwa.Mugihe icyifuzo cya interineti yihuse kandi yizewe gikomeje kwiyongera, amasosiyete yitumanaho akomeje gushakisha ikoranabuhanga rishya kugirango abakiriya babone ibyo bakeneye.Gigabit Passive Optical Network (GPON) ni tekinoroji ihindura inganda mugari.Muri iyi ngingo, tuzacukumbura ibyiza bya GPON, cyane cyane ikoreshwa rya port-16, ibyiciro bitatu bya OLT na FTTH optique ya optique kugirango tunoze neza imikorere yimikorere.

GPON ni fibre optique yububiko itanga serivise yihuta ya interineti, ijwi, na videwo kubakoresha amazu nubucuruzi.Ikoresha ingingo-kuri-kugwiza topologiya, ikoresha pasitiki optique itandukanya gukwirakwiza amakuru kubakiriya benshi icyarimwe.GPON ikoresha uburyo bwo gutwara Layeri 2 kugirango yohereze amakuru, itanga umurongo utangaje wa 2,5 Gbps kumanuka na 1.25 Gbps hejuru.

Intangiriro y'urusobe rwa GPON ni umurongo wa optique (OLT).Ubushobozi bwa OLT bwa Layeri 3 butuma igabanywa ryumutungo wurusobe hamwe nubwenge bwa paketi.Hamwe na OLT ishyigikira ubushobozi bwa Layeri 3, abatanga itumanaho barashobora kwemeza ko traffic igenda neza, kugabanya umuvuduko, no kuzamura imikorere y'urusobe.Byongeye kandi, Layeri 3 OLTs itanga ibimenyetso byumutekano bigezweho nko gushungura IP no kurinda firewall kugirango urinde urusobe rushobora guhungabana.

Moderi ya fibre-to-home (FTTH) ikoreshwa na tekinoroji ya GPON kandi ikoresha fibre optique kugirango itange fibre itaziguye kumazu cyangwa mubucuruzi.Bifite ibyambu byinshi 16, ibyo bikoresho bito, byoroheje birashobora gukemura byoroshye gukwirakwiza no guhagarika ibimenyetso bya optique, bigatuma imiyoboro ihuza imiyoboro yose.Amashanyarazi ya FTTH akora nk'ikiraro hagati ya fibre optique na Ethernet, ituma amakuru yihuta yohereza amakuru na serivisi zitumanaho zizewe.

GPON ifite ibyiza byinshi iyo ihujwe nuburyo butatu bwa OLT na FTTH optique.Ubwa mbere, itanga ubushobozi butagereranywa bwumurongo kugirango uhuze abakoresha amakuru bakeneye.Ikoranabuhanga kandi rigabanya gukoresha ingufu, rikaba igisubizo cyangiza ibidukikije.Byongeye kandi, ubunini bwa GPON butuma ibikorwa bigura imiyoboro ihendutse kandi ibikorwa remezo-bizaza.

Muri make, guhuza ibyambu 16, ibyiciro bitatu bya OLT na FTTH optique yahinduye byimazeyo umurongo mugari.Ikoranabuhanga rya GPON rizana imiyoboro yihuse, gucunga neza umutungo no kongera umutekano ku miyoboro y'itumanaho.Mugukoresha GPON, abatanga serivise barashobora guha abakiriya babo interineti idafite interineti, amajwi na videwo byujuje kandi birenze ibyo bategerejweho muriki gihe cya digitale.
