Uthungelwano lwe-EPON lusebenzisa indlela ye-FTTB ukwenza uthungelwano, kwaye iiyunithi zayo zenethiwekhi ezisisiseko zii-OLT kunye ne-ONU. I-OLT ibonelela ngamazibuko e-PON amaninzi kwizixhobo ze-ofisi ephakathi ukuqhagamshela kwizixhobo ze-ONU; I-ONU sisixhobo somsebenzisi ukubonelela ngedatha ehambelanayo kunye nojongano lwezwi ukuqonda inkonzo yomsebenzisi...

I-ONU (iyunithi yenethiwekhi yokukhanya) indawo yokukhanya. I-ONU yohlulwe kwiyunithi esebenzayo yenethiwekhi ye-optical network kunye nelayibrari ye-passive optical network unit. Ngokuqhelekileyo, izixhobo ezixhotyiswe ngokujongwa kwenethiwekhi kubandakanya i-optical receiver, i-uplink optical transmitter kunye ne-multiple bridge amplifiers ibizwa ngokuba yi-optical node ....

Ngophuhliso lwetekhnoloji yedijithali, itekhnoloji yonxibelelwano lwe-optical kunye nobuchwepheshe besoftware kunye nokusetyenziswa okubanzi kweprotocol ye-TCP/IP, inethiwekhi yonxibelelwano, uthungelwano lwekhompyuter kunye nothungelwano lukamabonwakude luya kudibana kunye kwaye lumanyene phantsi kwe-IP ekwaziyo ukubonelela ngelizwi, ...

I-FTTH i-Fiber Circuit Classification I-transmission layer ye-FTTH yahlulwe yangamacandelo amathathu: i-Duplex (i-dual fiber bidirectional) loop, i-Simplex (i-fiber bidirectional enye) i-loop kunye ne-Triplex (i-fiber enye yeendlela ezintathu) loop. phakathi kwesiphelo seOLT kunye ne-ON...

I-transceiver ye-fiber optical transceiver yiyunithi yokuguqula imidiya ye-Ethernet etshintshisa umgama omfutshane ojijekileyo weempawu zombane kunye neempawu ze-optical ezide. Ikwabizwa ngokuba sisiguquli sefayibha kwiindawo ezininzi. Iimveliso zisetyenziswa ngokubanzi kwiindawo zothungelwano zokwenyani apho i-Eth...

Ukusetyenziswa kweTekhnoloji ye-EPON kwi-FTTx iNethiwekhi yokuFikelela kwi-EPON I-teknoloji ye-FTTx esekelwe kwi-EPON ineenzuzo ze-bandwidth ephezulu, ukuthembeka okuphezulu, iindleko zokugcinwa okuphantsi, kunye nobuchwepheshe obuvuthiweyo. Okwesibini, yazisa imodeli yesicelo esiqhelekileyo se-EPON kwiFTTx, kwaye emva koko ihlalutya imiba ephambili ye-EPO...
