Q4: Ma sheegi kartaa maxay ku kala duwan yihiin ONT & ONU?
J: Ma jiro farqi u dhexeeya nuxurka, labaduba waa aaladaha isticmaaleyaasha.Waxa kale oo aad odhan kartaa ONT waa qayb ka mid ah ONU.
Q5: Waa maxay FTTH/FTTO?
Waa maxay FTTH/FTTO?
XGSPON (10 Gigabit Symmetric Passive Optical Network) tignoolajiyada ayaa wax ka beddeshay isgaarsiinta fiber optic-ga, taasoo keentay xawli ku wareejinta xogta degdega ah, kordhinta xawaaladaha iyo waxqabadka shabakadda oo la xoojiyay.Si loo gaaro isku xirnaan aan kala go 'lahayn oo loo daboolo baahida sii kordheysa ee codsiyada casriga ah, bixiyeyaasha adeegyadu waxay si joogto ah ugu dadaalayaan inay geeyaan terminal aad u hufan oo hufan (OLTs).Balooggan, waxaan ku sahamin doonaa hal-abuurradii ugu dambeeyay ee tignoolajiyada XGSPON.
GPON (Gigabit Passive Optical Network) ayaa dhidibbada u taagay isgaadhsiinta xawaaraha sare ee fiber optic-ga, waxaana ku xigtay XGPON (10 Gigabit PON) oo bixisa xawaarahooda xawliga ah.Si kastaba ha ahaatee, XGSPON waxay sii socotaa hal talaabo oo dheeraad ah, taasoo awood u siinaysa xogta simmetrical ah ee 10 Gbps labadaba gudbinta kor iyo hoosba, taasoo keentay in si degdeg ah, isku xirnaan la isku halleyn karo.
Dhaqan ahaan, OLT-yada waxaa lagu habeeyey dekedo yar.Si kastaba ha ahaatee, si loo waafajiyo tirada sii kordheysa ee isticmaalayaasha iyo aaladaha adduunka maanta ku xiran, OLT-yada leh 8 dekedood ayaa sii kordhaya caan.Cufnaanta dekeddan ee la balaadhiyey ayaa u sahlaysa bixiyayaasha adeegga inay u hoggaansamaan macaamiil ballaadhan, taasoo ka dhigaysa isku xidhka fiber-ka oo ay heli karaan shakhsiyaad iyo ganacsiyo badan.
Lakabka 3 shaqaynta:
Isku-dubbaridka shaqada lakabka 3 ee OLT waxay furaysaa awoodo marineed oo ballaaran, si kor loogu qaado waxqabadka shabakada iyo maamulka.Lakabka 3 furayaasha ayaa mas'uul ka ah hagidda xirmooyinka xogta ee shabakadaha kala duwan, kor u qaadista xogta hufan iyo yaraynta ciriiriga shabakada.Marka la isku daro shaqada lakabka 3 ee OLT, adeeg bixiyayaasha ayaa wanaajin kara waxqabadka shabakada, hubinta habaynta xogta hufan, iyo kor u qaadida guud ahaan khibrada isticmaale.
OLT-gii ugu dambeeyay wuxuu isku daraa tignoolajiyada XGSPON oo leh 8 dekedood iyo shaqeynta Lakabka 3, oo bixiya faa'iidooyin badan.Adeeg bixiyayaashu waxay ku raaxaysan karaan korodhka awoodda isticmaale, hufnaanta shabakada oo la hagaajiyay iyo maaraynta la fududeeyay.Isticmaalayaasha dhamaadka ah, dhanka kale, waxay la kulmi karaan xawli internet oo xawli ku socda, isku xirnaanta la isku halayn karo, iyo waxqabadka la xoojiyey ee codsiyada xog-warranka ah sida baahinta fiidiyowga, ciyaaraha khadka tooska ah, iyo adeegyada daruuraha.
Maaddaama ay tignoolajiyadu sii socoto in ay horumarto, baahida loo qabo xawaarihiisa sare, isku xirka la isku halayn karo ayaa sii kordhaya.Tiknoolajiyada XGSPON, oo leh awooddeeda gudbinta xogta ee la xoojiyey, oo ay weheliso OLT-yadii ugu dambeeyay ee leh 8-dekedood iyo awoodaha Lakabka 3, ayaa bixiya xal adag si loo buuxiyo shuruudahan.Qaadashada hal-abuurkan cusub, bixiyeyaasha adeegga waxay si wax ku ool ah u dabooli karaan baahida sii kordheysa ee isku xirnaanta casriga ah, iyagoo siinaya macaamiisha waxqabad shabakad heer sare ah iyo khibrad isticmaale oo aan la mid ahayn.
