I-1*9 zipakishiweimodyuli yokubonaimveliso yaveliswa okokuqala ngo-1999. Yimveliso yemodyuli esisigxina.Ngokuqhelekileyo iphiliswa ngokuthe ngqo (i-soldered) kwibhodi yesekethe yesixhobo sonxibelelwano kwaye isetyenziswe njengemodyuli esisigxina ye-optical module.Ngamanye amaxesha ikwabizwa ngokuba yi-9-pin okanye i-9PIN yemodyuli yokubona..

Njengoko igama lisitsho, le modyuli yefiber optic ine-PIN ezilithobas,eyona ndlela ixhaphakileyo yokupakishwa kweemodyuli zangaphambili zamehlo, kwaye ikwaluhlobo olunemfuno enkulu yemarike.Abaguquli be-Multimode kunye nezinye iindawo zolawulo lwamashishini.Ukubeka nje, imodyuli ye-1 × 9 imodyuli ye-optical sisixhobo sonxibelelwano esisebenzisa amaza okukhanya njenge-carrier wave kunye ne-optical fibers njengendlela yokudlulisa.Isebenzisa umthombo wokukhanya ukuguqula izibonakaliso zombane kwiimpawu ze-optical, ezifakwe kwi-fiber optical ukuhanjiswa.Umqondiso uyandiswa, umise kwaye uhlaziywe ukubuyisela umqondiso wokuqala wombane.
