    Aqoon buuxda oo ku saabsan APON, BPON, EPON, GPON

    Waqtiga boostada: Jul-02-2021

    PON (Passive Optical Network) macneheedu waxa weeye ma jiro wax qalab ah oo shaqaynaya oo kaliya adeegso Fiber Optical iyo Qalabka Passive inta u dhaxaysa OLT (Terminal Line Optical) iyo Onu Iyo PON ee tignoolajiyada ugu weyn si loo hirgeliyo FTTB/FTTH, taas oo inta badan qaadata barta qaabdhismeedka shabakad-dhibcaha badan.

    Waxaa jira waxyaabo badan oo ku jira Tignoolajiyada PON, PON Technology ayaa si joogto ah u soo noqnoqonaysa oo cusboonaysiisay. Teknolojiyadda XPON waxay ka soo saartay APON, BPON, iyo ka dib EPON iyo GPON. Waxaa jira habab kala duwan oo gudbin iyo heerar gudbin oo la sameeyay waqtiyo kala duwan.

    Waa maxay APON?

    Dhammaadkii sagaashameeyadii, ITU (Ururka Isgaarsiinta Caalamiga ah) ayaa markii ugu horreysay soo jeedisay APON iyadoo adeegsanaysa Habka Wareejinta Asynchronous (ATM) ee Isgaarsiinta xirmada. APON waxay isticmaashaa isku dhufashada dhexe iyo xisaabaadka ee ATM, oo ay weheliso wadaagista shaqada qaybiyaha dadban ee fiber indhaha iyo Terminalka Khadka Tooska ah, taas oo ka dhigaysa qiimaha ka hooseeya 20% ~ 40% marka loo eego nidaamka soo jireenka ah ee PDH/SDH ee ku salaysan wareegga beddelashada.

    Waa maxay BPON?

    Horumarka degdega ah ee Tignoolajiyada Ethernet, APON asal ahaan hadda lama isticmaalo. Waqtigaan, fikradda Shabakadda Shabakadda Baadhitaanka ee Shabakadda Baadhitaanka (BPON) ayaa la soo jeediyay. BPON waa kobcinta heerka APON, asal ahaan loo yaqaan APON, laakiin markii dambe loo beddelay BPON ujeedooyin kala duwan. BPON waxay ku salaysan tahay borotokoolka ATM, oo leh xawaarihii kor iyo hoosba ee 155Mbpas iyo 622Mbps siday u kala horreeyaan. Isla mar ahaantaana, Waxay ku darsataa qoondaynta xawaaraha xawaaraha firfircoon, ilaalinta iyo hawlaha kale, waxayna bixin kartaa marinka Ethernet, gudbinta fiidiyowga, Khadadka kirada ah ee xawaaraha sare leh iyo adeegyo kale.

    Waa maxay EPON?
    Sababo la xiriira qiimaha sare ee BPON, waxaa markii dambe lagu bedelay ka kharash-ool ah iyo dhaqsiyaha badan EPON.EPON (Ethernet Passive Optical Network) waa Ethernet Passive Optical Network.EPON PON technology oo ku salaysan Ethernet waxay isku daraysaa faa'iidooyinka tignoolajiyada PON iyo Tignoolajiyada Ethernet, waxay qabataa qaab dhismeedka Point to Multi-point, gudbinta fibre indhaha ee dadban,

    Sababo la xiriira qiimaha sare ee BPON, waxaa markii dambe lagu bedelay ka kharash-ool ah iyo dhaqsiyaha badan EPON.EPON (Ethernet Passive Optical Network) waa Ethernet Passive Optical Network.EPON PON technology oo ku salaysan Ethernet waxay isku daraysaa faa'iidooyinka tignoolajiyada PON iyo Tiknoolajiyada Ethernet, waxay qabataa qaab-dhismeedka Point-to- Multi-point, gudbinta fibre-gaaban ee indhaha, waxayna bixisaa adeegyo kala duwan oo Ethernet ah "Maylkii u dambeeyay" isgaarsiinta.

    Waa maxay GPON?

    GPON (Gigabit-Capable Passive Optical Network) waa Gigabit Passive Optical Network ama Gigabit Passive Optical Network.EPON iyo GPON waxay isticmaalaan heerar kala duwan, GPON-na waxaa la sheegaa in uu aad u horumarsan yahay, awoodna u leeyahay in uu gudbiyo bandwidth ka badan oo uu qaado isticmaaleyaal ka badan EPON. Inkastoo GPON uu leeyahay Faa'iidooyinka xawaaraha sare iyo adeegyada kala duwan marka la barbar dhigo EPON, tignoolajiyada GPON aad bay u adag tahay kharashkeeduna wuu ka sarreeyaa kan EPON. Sidaa darteed, wakhtigan, EPON iyo GPON waa teknoolojiyadda ugu badan ee loo adeegsado marinka ballaadhan ee PON, iyo ikhtiyaarka tiknoolijiyada waxay ku xiran tahay wax badan oo ku saabsan kharashka helitaanka fiber indhaha iyo shuruudaha ganacsiga.GPON waxay si fiican ugu habboonaan doontaa macaamiisha leh xawaaraha sare ee xawaaraha sare, adeegyo badan, QoS iyo shuruudaha amniga, iyo tignoolajiyada ATM-ka oo ah laf-dhabarka. Horumarka mustaqbalka waa bandwidth sare, tusaale ahaan. , Tiknoolajiyada EPON/GPON waxay horumarisaa 10 G EPON / 10 G GPON, xajmiga xajmiga ayaa la sii wanaajin doonaa.

    Ogaanshaha wax badan oo ku saabsan APON,BPON,EPON,GPON

    Maaddaama baahida awoodda ee bixiyeyaasha shabakadu ay sii kordhayaan, kala-duwanaanta shabakadaha gelitaanka waa inay sidoo kale ballaariyaan si loo daboolo baahidan sii kordheysa. Faa'iidooyinka tignoolajiyada PON waa in ay yarayn karto isticmaalka ilaha lafdhabarta lafdhabarta iyo badbaadinta maalgashiga. Qaabdhismeedka shabakada dabacsan, awood xoog leh oo lagu ballaariyo karti iwm.
