64, ngokubanzi ingaphantsi kwe-10.
1. Ngokwethiyori, ama-64 anokudityaniswa, kodwa xa kujongwa ukuncitshiswa kokukhanya kunye novakalelo lwe-onu ekukhanyeni, ngokubanzi kwizicelo ezisebenzayo, inani loqhagamshelo ngezibuko ngalinye lingaphantsi kwe-10. Inani eliphezulu labasebenzisi abafikelelwa yi-olt linqunyelwe kakhulu ziimeko ezintathu, oko kukuthi, inani le-bandwidth yenkonzo kunye needilesi ze-MAC abasebenzisi abanokuzifumana.
I-terminal yomgca we-optical ye-2.olt (i-terminal yomgca we-optical) yomgca we-optical. Ekusetyenzisweni kwetekhnoloji ye-pon, izixhobo ze-olt zizixhobo ezibalulekileyo zeofisi ephakathi. Umsebenzi eziwenzayo kukudibanisa iswitshi yangaphambili ngentambo yenethiwekhi, ukuyiguqula ibe yisignali ye-optical, kunye nokusebenzisa i-optical fiber ukudibanisa ne-optical splitter ekupheleni komsebenzisi. Qaphela ulawulo, ulawulo kunye nemisebenzi yokwahlulahlula ye-onu yesixhobo se-terminal yomsebenzisi. Njengesixhobo se-onu, isixhobo se-olt sikwasisixhobo esidibeneyo se-optoelectronic.
3.onu (iyunithi yenethiwekhi yokukhanya) i-onu node yokukhanya. I-onu yahlulwe yaba yiyunithi yenethiwekhi yokukhanya esebenzayo kunye neyunithi yenethiwekhi yokukhanya engasebenziyo. Ngokubanzi, izixhobo ezixhotyiswe ngokubeka esweni inethiwekhi kuquka i-optical receiver, i-uplink optical transmitter, kunye nee-amplifier ezininzi ze-bridge zibizwa ngokuba yi-optical node.
