Ngokuthuthukiswa okuqhubekayo komkhawulokudonsa wenethiwekhi, ukuthuthukiswa okuqhubekayo kwemishini yokugcina, inkomfa yevidiyo enencazelo ephezulu, izinsizakalo zamafu, ukushintshaniswa kwedatha enkulu, ihhovisi leselula, njll., amabhizinisi asebenza kahle futhi avuleke kakhudlwana, ngaleyo ndlela akhuthaze ihhovisi elihlakaniphile nolwazi. zamabhizinisi, kanye nezidingo zomkhawulokudonsa wenethiwekhi nesivinini ziya ngokuya ziba phezulu.Ibhizinisi lendabuko kanye nekhempasi I-Lans inesidingo sokuthuthukiswa kwenethiwekhi lapho ibhekene nenselelo enkulu yomkhawulokudonsa ovela kulezi zinhlelo zokusebenza.
Ukwakhiwa kwayo yonke inethiwekhi yokubona
I-POL isebenzisa ubuchwepheshe be-PON, i-Passive Optical Network (PON) iyiphoyinti elikhomba-kuningi (i-P2MP) i-Passive Optical Network, ehlanganisa i-OLT(LM808E), i-ODN, ne-ONT.
I-POL(I-Passive Optical LAN)I-Passive all-optical LAN
Kunethiwekhi ye-POL, ukushintsha kokuhlanganisa ku-LAN yendabuko kuthathelwa indawo i-OLT(LM808E).Intambo yethusi evundlile ithathelwa indawo yi-fiber optical;Amaswishi okufinyelela athathelwa indawo yi-passive optical splitter.
I-ONT inikeza ungqimba 2 noma imisebenzi Yesendlalelo 3 ukuze ufinyelele kudatha yabasebenzisi, izinkonzo zezwi, nevidiyo ngamadivayisi anentambo noma angenantambo.
I-PON network downlink isebenzisa imodi yokusakaza: isignali yokubona ethunyelwe i-OLT(LM808E) ihlukaniswe yaba amasignali amaningi okubona anolwazi olufanayo nge-optical splitter futhi ithunyelwa ku-ONT ngayinye;I-ONT ithola ngokukhetha amaphakethe ayo ngokusekelwe kumathegi asemaphaketheni. futhi ilahla labo abane-Tag engahambisani.
Ukuqondiswa kwe-uplink yenethiwekhi ye-PON: I-OLT(LM808E) yabela ucezu lwesikhathi ku-ONT ngayinye.I-ONT ithumela amasignali ngokuqinile ngokuya ngalesi siqeshana sesikhathi futhi ivala imbobo yokubona ngokusekelwe kucezu lwesikhathi okungesona esayo.Indlela yokuhlela iwindi lesikhathi se-uplink incike kakhulu kubuchwepheshe obuhlukahlukene be-PON.
Ukuqonda isimiso sobuchwepheshe be-PON kusisiza ukuba sisebenzise lobu buchwepheshe ngobunyoninco ekwakhiweni kukagesi, ikakhulukazi izici ze-passive (akukho ukunikezwa kwamandla) zenethiwekhi yokusabalalisa optical, kanye nomehluko phakathi komklamo wokusabalalisa wephoyinti lokushintsha ngokwesiko ikakhulukazi isidingo sokunaka. .Ukuqinisekisa ukuthi amaphakethe ethrafikhi ezinhlangothini ezimbili athunyelwa ku-fiber eyodwa eyinhloko, i-PON ithatha imodi yokuhlukaniswa kwamagagasi.Ngemva kokuthuthukiswa ku-10 Gigabit PON, izingxenye ezine ze-wavelength zisetshenziselwa i-optical fiber multiplexing.
Umhlaba obonakalayo, Isixazululo se-Limee!Masiqhubeke nengxoxo yethu yomhlaba wonke optical ngokuzayo.
