I-1*9 zipakishiweimodeli ye-opticalumkhiqizo wakhiqizwa okokuqala ngo-1999. Kungumkhiqizo we-fixed optical module.Ivame ukuphulukiswa ngokuqondile (i-soldered) ebhodini lesifunda lemishini yokuxhumana futhi isetshenziswe njengemojula ye-optical engaguquki.Kwesinye isikhathi ibizwa nangokuthi i-9-pin noma i-9PIN optical module..

Njengoba igama lisho, le moduli ye-fiber optic ine-PIN eyisishiyagalolunyes,okuyindlela yokupakisha ejwayeleke kakhulu yamamojula wakuqala we-optical, futhi iwuhlobo olunesidingo esikhulu kakhulu semakethe.Iziguquli ze-Multimode nezinye izinkambu zokulawula zezimboni.Kalula nje, imojula ye-1 × 9 ye-optical iyithuluzi lokuxhumana elisebenzisa amaza alula njengegagasi elithwalayo kanye namafiber optical njengendlela yokudlulisa.Isebenzisa umthombo wokukhanya ukuze iguqule amasignali kagesi abe amasignali optical, afakwa ku-fiber optical ukuze adluliselwe.Isignali iyakhuliswa, ibunjwe futhi ivuselelwe ukuze kubuyiselwe isignali kagesi yasekuqaleni.
