Ingxoxo emfushane ngamathrendi embonini ye-PON

I. Isingeniso

Ngokuthuthuka okusheshayo kobuchwepheshe bolwazi kanye nesidingo esikhulayo sabantu samanethiwekhi anesivinini esikhulu, i-Passive Optical Network (PON), njengomunye wobuchwepheshe obubalulekile bokufinyelela amanethiwekhi, kancane kancane isetshenziswa kabanzi emhlabeni jikelele. Ubuchwepheshe be-PON, nezinzuzo zabo zomkhawulokudonsa ophezulu, izindleko eziphansi, kanye nokugcinwa kalula, buye baba amandla abalulekile ekukhuthazeni ukuthuthukiswa kwe-fiber-to-the-home (FTTH) kanye namanethiwekhi okufinyelela e-broadband. Lesi sihloko sizodingida izitayela zakamuva zentuthuko yemboni ye-PON futhi sihlaziye inkomba yentuthuko yesikhathi esizayo.

2. Uhlolojikelele lobuchwepheshe be-PON

Ubuchwepheshe be-PON ubuchwepheshe bokufinyelela i-fiber optical obusekelwe ezingxenyeni ze-passive optical. Isici sawo esiyinhloko ukuqedwa kwezinto zokusebenza ze-elekthronikhi ezisebenzayo kunethiwekhi yokufinyelela, ngaleyo ndlela kunciphisa inkimbinkimbi nezindleko zesistimu. Ubuchwepheshe be-PON ikakhulukazi buhlanganisa izindinganiso ezimbalwa ezifana ne-Ethernet Passive Optical Network (I-EPON) kanye ne-Gigabit Passive Optical Network (GPON). I-EPON ithatha isikhundla esibalulekile emakethe ngezinga layo eliguquguqukayo lokudluliswa kwedatha kanye nezinzuzo zezindleko, kuyilaphoI-GPONithandwa opharetha ngomkhawulokudonsa wayo ophezulu namandla okuqinisekisa ikhwalithi yesevisi eqinile.

3. Izitayela zakamuva embonini ye-PON

3.1 Ukuthuthukiswa komkhawulokudonsa:Njengoba isidingo sabasebenzisi samanethiwekhi anesivinini esikhulu sikhula, ubuchwepheshe be-PON nabo buthuthukiswa njalo. Njengamanje, ubuchwepheshe be-PON obuphezulu bomkhawulokudonsa obufana ne-10G-EPON kanyeI-XG-PONziye zavuthwa kancane kancane futhi zafakwa ekusetshenzisweni kwezentengiso, zinikeza abasebenzisi umuzwa wenethiwekhi osheshayo futhi ozinzile.
3.2 Intuthuko edidiyelwe:Ukuhlanganiswa nokuthuthukiswa kobuchwepheshe be-PON nobunye ubuchwepheshe bokufinyelela sekuphenduke inkambiso entsha. Isibonelo, inhlanganisela ye-PON nobuchwepheshe bokufinyelela okungenantambo (obufana ne-5G) ingafinyelela ukuhlanganiswa kwamanethiwekhi angaguquki kanye namaselula futhi inikeze abasebenzisi ngamasevisi enethiwekhi avumelana nezimo futhi alula.
3.3 Ukuthuthukiswa okuhlakaniphile:Ngokuthuthuka okusheshayo kobuchwepheshe obufana ne-inthanethi Yezinto kanye ne-cloud computing, amanethiwekhi e-PON abona kancane kancane ukuthuthukiswa okuhlakaniphile. Ngokwethula ukuphathwa okuhlakaniphile, ukusebenza nokugcinwa, kanye nobuchwepheshe bezokuphepha, ukusebenza kahle kwenethiwekhi ye-PON kuyathuthukiswa, izindleko zokusebenza nezokulungisa ziyancishiswa, futhi amandla okuqinisekisa ukuphepha ayathuthukiswa.

4. Isiqondiso sokuthuthukiswa kwekusasa

4.1 Inethiwekhi ye-All-optical network:Ngokuzayo, ubuchwepheshe be-PON buzoqhubeka buthuthuke bube yinethiwekhi ye-All-optical ukuze kuzuzwe ukudluliswa kwe-optical ekupheleni kuya ekupheleni. Lokhu kuzothuthukisa futhi umkhawulokudonsa wenethiwekhi, kunciphise ukubambezeleka kokudlulisela futhi kuthuthukise ulwazi lomsebenzisi.
4.2 Intuthuko eluhlaza neqhubekayo:Njengoba ukongiwa kwamandla kanye nokuncishiswa kokungcola kuba yisivumelwano somhlaba wonke, ukuthuthukiswa okuluhlaza nokusimeme kobuchwepheshe be-PON nakho sekube yisiqondiso esibalulekile sentuthuko yesikhathi esizayo. Yehlisa ukusetshenziswa kwamandla kanye nokukhishwa kwekhabhoni kwamanethiwekhi e-PON ngokusebenzisa ubuchwepheshe nemishini yokonga amandla, ngokuthuthukisa izakhiwo zenethiwekhi nezinye izindlela.
4.3 Ukuphepha kwenethiwekhi:Ngokuvela kaningi kwezehlakalo zokuphepha njengokuhlaselwa kwenethiwekhi nokuvuza kwedatha, imboni ye-PON idinga ukunaka kakhulu ukuphepha kwenethiwekhi ohlelweni lokuthuthukisa. Thuthukisa ukuvikeleka nokuthembeka kwenethiwekhi ye-PON ngokwethula ubuchwepheshe bokubethela obuthuthukisiwe nezindlela zokuvikela ukuphepha.

5. Isiphetho

Njengobunye bobuchwepheshe obubalulekile endimeni yenethiwekhi yokufinyelela yamanje, ubuchwepheshe be-PON bubhekene nezinselelo namathuba avela ezinkambisweni eziningi ezifana nokuthuthukiswa komkhawulokudonsa, ukuthuthukiswa kokuhlangana, nokuthuthukiswa okuhlakaniphile. Ngokuzayo, ngokuthuthukiswa okuqhubekayo kwamanethiwekhi abona konke, ukuthuthukiswa okusimeme okuluhlaza, nokuphepha kwenethiwekhi, imboni ye-PON izongenisa indawo ebanzi yokuthuthukiswa kanye nokuncintisana kwezimakethe okukhulu.
