Cassette EPON OLT waa isku dhafka sare iyo awoodda yar ee OLT loogu talagalay hawl-wadeenada - gelitaanka iyo isku xirka xarunta ganacsiga.Waxay raacaysaa IEEE802.3 ah heerarka farsamada waxayna buuxisaa shuruudaha qalabka EPON OLT ee YD/T 1945-2006 Shuruudaha farsamada ee helitaanka shabakad-ku salaysan Ethernet Passive Optical Network (EPON) iyo Shiinaha telecom EPON shuruudaha farsamada 3.0.Waxay leedahay furfurnaan aad u fiican, awood weyn, isku hallayn sare, shaqo software dhammaystiran, ka faa'iidaysi hufan oo ka faa'iideysiga ganacsiga iyo awoodda taageerada ganacsiga ee Ethernet, oo si ballaaran loogu dabaqay daboolka shabakadda dhamaadka-dhamaadka hawlwadeenka, dhismaha shabakadda gaarka ah, gelitaanka xarunta ganacsiga iyo dhismaha shabakada kale ee gelitaanka.
Cassette EPON OLT waxay bixisaa 4/8 dekedaha EPON, 4xGE Ethernet dekedo iyo 4x10G(SFP+) dekedaha kor u kaca.Dhererku waa kaliya 1U si sahlan loo rakibo iyo badbaadinta booska.Waxay qabataa tignoolajiyada horumarsan, iyadoo bixisa xal wax ku ool ah EPON.Waxaa intaa dheer, waxay u badbaadisaa kharash badan oo loogu talagalay hawl-wadeenada sababtoo ah waxay taageeri kartaa isku-xidhka isku-dhafka ah ee ONU ee kala duwan. Sida tignoolajiyadu ay sii socoto inay hore u socoto, baahida loo qabo isku xirka internetka ee la isku halleyn karo ayaa sii kordhaya.Maaddaama baahida loo qabo wareejinta xogta aan kala go 'lahayn ay sii kordheyso, bixiyeyaasha adeegga waxay si joogto ah u raadinayaan xalal cusub si ay u daboolaan baahida macaamiisha.Hal xal oo si weyn loo fiirsaday ayaa ah is dhexgalka 10 Gigabit Ethernet Passive Optical Network (10GE EPON) Terminal Optical Line Terminal (OLT) oo loo galay Lakabka 3 Fiber-to-the-Home (FTTH).
Tiknoolajiyada 10GE EPON OLT waxay bixisaa 10 Gbps heerka xogta, toban jeer ka dhakhso badan Gigabit Ethernet-ka caadiga ah, taas oo awood u siinaysa isgaadhsiin waxtar sare leh oo qiimo jaban ah.Habkani wuxuu bixiyaa khibrad isticmaale oo heer sare ah oo loogu talagalay codsiyada bandwidth-degdegga ah sida qulqulka fiidiyoowga ee qeexitaanka sare, ciyaaraha khadka tooska ah, iyo adeegyada daruuraha ee waqtiga-dhabta ah.Sidaa darteed, nidaamyada 10GE EPON OLT waxay aad ugu baahan yihiin gudbinta nuxurka warbaahinta kala duwan.
Mid ka mid ah faa'iidooyinka ugu muhiimsan ee LIMEE 10GE EPON OLT ee shabakadaha FTTH waa awooda lagu taageerayo ilaa afar isku xidhka Shabakadda Shabakadda Baadhitaanka (PON).Xidhiidhada PON waxay u oggolaanayaan in fiber-ka la wadaago macaamiisha badan, iyagoo siinaya xal-wax-ku-ool ah oo loogu talagalay bixiyeyaasha adeegga iyadoo la ilaalinayo isku-xirnaanta xawaaraha sare ee isticmaalayaasha dhamaadka.Iyadoo la adeegsanayo hal xariiq fiber optic ah, nidaamka 10GE EPON OLT wuxuu dabooli karaa baahida tiro badan oo macaamiisha ah oo leh maalgelin kaabayaasha ugu yar.
Intaa waxaa dheer, isku-dhafka lakabka 3 ee shaqada marin-haweedka ayaa sii wanaajinaya shaqada tignoolajiyada 10GE EPON OLT.Lakabka 3-aad ee jiheynta waxa uu sahlayaa gudbinta xirmada IP hufan ee shabakadaha kala duwan, awood u siinaya maaraynta taraafikada firfircoon iyo kordhinta adkeysiga shabakada.Habkani waxa uu u sahlayaa adeeg bixiyayaasha in ay wanaajiyaan ilahooda shabakadeed, iyaga oo hubinaya khibrad isticmaale oo aan kala go' lahayn oo aan kala go' lahayn xitaa inta lagu jiro xilliyada ciriiriga sare ee shabakadaha.
Intaa waxaa dheer, geynta tignoolajiyada 10GE EPON OLT ee shabakada FTTH waxay siisaa faa'iidooyin kala duwan adeeg bixiyayaasha iyo isticmaalayaasha dhamaadka si isku mid ah.Bixiyeyaasha adeeggu waxay ka faa'iidaysan karaan dhimista kharashyada hawlgalka maadaama dayactirka iyo maamulka shabakadu ay noqdaan kuwo fudud.Intaa waxaa dheer, adoo ka faa'iideysanaya miisaanka 10GE EPON OLT, bixiyeyaasha adeegyadu waxay si fudud u dabooli karaan baahida sii kordheysa ee adeegyada xajmiyeedka sare, taas oo ka dhigaysa maalgashi mustaqbalka ah.
Isticmaalayaasha ugu dambeeya, isku dhafka 10GE EPON OLT tignoolajiyada waxay la macno tahay inay la kulmaan xawaare sare oo internet ah, isku halaynta aan la barbar dhigi karin iyo daahitaanka hooseeya, oo ka baxsan xaddidaadda isku xirka fidsan dhaqameed.Haddi ay tahay qul-qulka fiidyaha aadka u sarreeya ee aan kala go 'lahayn ama ciyaaraha xaqiiqada dhabta ah, isticmaalayaashu waxay ku raaxaysan karaan waayo-aragnimada khadka ee la xoojiyey ee aan kala go'a lahayn ee beddela habka ay ula falgalaan adduunka dhijitaalka ah.
Eray ahaan, isku dhafka tignoolajiyadan OLT ee lakabka 3 ee shabakadda FTTH waxay calaamad u tahay boob weyn oo ku saabsan isku xirka fiber indhaha.Isku darka heerka xogta 10 Gbps, awoodaha wadaagga fiber-ka, lakabka 3 awoodaha wadista iyo kharash-ku-oolnimada ayaa ka dhigaysa nidaamka LIMEE EPON OLT mid ku habboon bixiyeyaasha adeegga raadinaya inay macaamiishooda siiyaan xiriirro degdeg ah oo la isku halleyn karo.Maaddaama baahida loo qabo intarneetka xawaarihiisu sarreeyo ay sii kordheyso, qaadashada tignoolajiyadan cusub waxay albaabada u furaysaa adduunyo suurtagal ah, iyada oo wax ka beddeleysa habka aan isku xirno, xiriirka iyo khibradda u leenahay saaxadda dhijitaalka ah.
