XPON Technology Overview
I-XPON iteknoloji yokufikelela kwi-broadband esekelwe kwi-Passive Optical Network (PON). Ifezekisa ukuhanjiswa kwedatha ye-speed-speed and big-capacity through single-fiber bidirectional transmission. Itekhnoloji ye-XPON isebenzisa iimpawu zokuhanjiswa kwe-passive ye-optical signals ukusabalalisa izibonakaliso ze-optical kubasebenzisi abaninzi, ngaloo ndlela iqonda ukwabelana ngemithombo yenethiwekhi elinganiselwe.
Ubume benkqubo ye-XPON
Inkqubo ye-XPON ibandakanya ubukhulu becala: i-terminal ye-optical line (OLT), iyunithi yenethiwekhi ye-optical (ONU) kunye ne-passive optical splitter (Splitter). I-OLT ikwi-ofisi esembindini yabasebenzi kwaye inoxanduva lokubonelela ngojongano lwecala lothungelwano kunye nokuhambisa imijelo yedatha kuthungelwano olukumgangatho ophezulu olufana nothungelwano lwemimandla yemetropolitan. I-ONU ifumaneka ekupheleni komsebenzisi, ukubonelela abasebenzisi ngokufikelela kwinethiwekhi kunye nokuqonda ukuguqulwa kunye nokucubungula ulwazi lwedatha. Abaqhekeki be-Passive optical basasaza imiqondiso ye-optical kwi-multipleI-ONUs ukufikelela kwinethiwekhi.

Itekhnoloji yokuhambisa i-XPON
I-XPON isebenzisa iteknoloji ye-time division multiplexing (TDM) ukufezekisa ukuhanjiswa kwedatha. Kwitekhnoloji ye-TDM, ii-slots zexesha ezahlukeneyo (i-Time Slots) zahlulwe phakathi kwe-OLT kunye ne-ONU ukuqonda ukuhanjiswa kwedatha ye-bidirectional. Ngokukodwa, iOLTyabela idatha kwii-ONU ezahlukeneyo ngokweendawo zokubeka ixesha kwicala elinyukayo, kwaye isasaze idatha kuzo zonke ii-ONU kwicala elisezantsi. I-ONU ikhetha ukufumana okanye ukuthumela idatha ngokwexesha lokuchongwa kwexesha.

XPON data encapsulation kunye nohlalutyo
Kwinkqubo ye-XPON, i-data encapsulation ibhekisela kwinkqubo yokongeza ulwazi olufana nezihloko kunye neetrailer kwiiyunithi zedatha ezithunyelwa phakathi kwe-OLT kunye ne-ONU. Olu lwazi lusetyenziselwa ukuchonga uhlobo, indawo ekuyiwa kuyo kunye nezinye iimpawu zeyunithi yedatha ukwenzela ukuba isiphelo sokufumana sinokucazulula kwaye siqhube idatha. Ukuhlaziywa kwedatha yinkqubo apho isiphelo sokufumana sibuyisela idatha kwifomathi yayo yokuqala ngokusekelwe kwingcaciso ye-encapsulation.
Inkqubo yokuhanjiswa kwedatha ye-XPON
Kwinkqubo ye-XPON, inkqubo yokuhanjiswa kwedatha ikakhulu ibandakanya la manyathelo alandelayo:
1. I-OLT ifaka idatha kwiimpawu ze-optical kwaye ithumele kwi-passive optical splitter ngekhebula le-optical cable.
2. I-passive optical splitter isasaza isignali ye-optical kwi-ONU ehambelanayo.
3. Emva kokufumana isignali ye-optical, i-ONU yenza ukuguqulwa kwe-optical-to-electrical kwaye ikhuphe idatha.
4. I-ONU imisela indawo ekuyiwa kuyo idatha esekelwe kulwazi olukwi-data encapsulation, kwaye ithumela idatha kwisixhobo esihambelanayo okanye umsebenzisi.
5. Isixhobo esifumanayo okanye umsebenzisi uhlalutya kwaye asebenze idatha emva kokuyifumana.
Indlela yokhuseleko ye-XPO
Iingxaki zokhuseleko ezijongene ne-XPON ikakhulu zibandakanya ukungena ngokungekho mthethweni, uhlaselo olunolunya kunye nokuvalelwa kwedatha. Ukusombulula ezi ngxaki, inkqubo XPON isebenzisa iindlela ezahlukeneyo zokhuseleko:
1. Indlela yokuqinisekisa: Yenza uqinisekiso lwesazisi kwi-ONU ukuqinisekisa ukuba ngabasebenzisi abasemthethweni kuphela abanokufikelela kuthungelwano.
2. Indlela yoguqulelo oluntsonkothileyo: Fihla idatha ethunyelweyo ukunqanda ukuba idatha ingavalwa okanye ibhujiswe.
3. Ulawulo lokufikelela: Ukuthintela amalungelo abasebenzisi okufikelela ukuthintela abasebenzisi abangekho mthethweni ekusebenziseni kakubi imithombo yothungelwano.
4. Ukubeka iliso kunye nokothusa: Ukubeka iliso kwimo yenethiwekhi ngexesha langempela, i-alamu ngexesha xa iimeko ezingaqhelekanga zifunyenwe, kwaye uthathe amanyathelo okhuseleko ahambelanayo.
Ukusetyenziswa kwe-XPON kwinethiwekhi yasekhaya
Itekhnoloji ye-XPON inamathuba osetyenziso olubanzi kuthungelwano lwasekhaya. Okokuqala, i-XPON inokufikelela kwi-Intanethi ngesantya esiphezulu ukuhlangabezana neemfuno zabasebenzisi basekhaya ngesantya sothungelwano; okwesibini, i-XPON ayifuni i-wiring yangaphakathi, enciphisa iindleko zokufakela kunye nokugcinwa kweenethiwekhi zasekhaya; Ekugqibeleni, i-XPON inokuqonda ukudityaniswa kweenethiwekhi ezininzi, ukudibanisa iifowuni, iiTV kunye neekhompyutha. Inethiwekhi idityaniswe kuthungelwano olufanayo ukuququzelela ukusetyenziswa komsebenzisi kunye nolawulo.
