64, ngokubanzi ngaphantsi kwe-10.
1. Kwithiyori, i-64 inokudityaniswa, kodwa ngokuqwalasela ukuthotywa kokukhanya kunye novelwano lwe-onu ekukhanyeni, kwizicelo ezisebenzayo eziqhelekileyo, inani loxhumo kwi-port nganye lingaphantsi kwe-10. Inani eliphezulu labasebenzisi abafikelelwe yi-olt ikakhulu. umda ngeemeko ezintathu, ezizezi, inani le-bandwidth yenkonzo kunye needilesi ze-MAC ezinokufunyanwa ngabasebenzisi.
I-2.olt (i-terminal yomgca we-optical) i-terminal ye-optical line.Ekusetyenzisweni kobuchwepheshe be-pon, izixhobo ze-olt sisixhobo esibalulekileyo se-ofisi ephakathi.Umsebenzi owuqondayo kukudibanisa i-front-end switch kunye nentambo yenethiwekhi, ukuyiguqula ibe ngumqondiso we-optical, kwaye usebenzise i-fiber optical ukudibanisa kunye ne-optical splitter ekupheleni komsebenzisi.Qondanisa ulawulo, ulawulo kunye nemisebenzi eyahluka-hlukeneyo ye-onu yesixhobo setheminali somsebenzisi.Njengesixhobo se-onu, isixhobo se-olt sikwasisixhobo esihlanganisiweyo se-optoelectronic.
I-3.onu (iyunithi yenethiwekhi ye-optical) i-optical node.i-onu yahlulwe yaba yiyunithi yothungelwano olubonakalayo olusebenzayo kunye neyunithi yothungelwano engabonakaliyo.Ngokubanzi, izixhobo ezixhotyiswe ngokujongwa kwenethiwekhi kubandakanya i-optical receiver, i-uplink optical transmitter, kunye ne-amplifiers ezininzi zebhulorho zibizwa ngokuba yi-optical node.
