Igama eliphelele le-BOB lithi BOSA On Board. I-BOB iyisisombululo sezobuchwepheshe kanye nenqubo yokukhiqiza "yokuphula yonke ibe izingxenye". Isixazululo se-BOB senza ukuklanywa kwebhodi lesifunda lamatheminali asekhaya kube lula, kusiza ukunciphisa umthamo wetheminali, futhi kusize ukufakwa nokubeka ekhaya. Ngokuthuthuka okusheshayo kwamanethiwekhi olwazi lwasekhaya, isidingo sabantu sejubane lenethiwekhi siyanda, futhi ukuvela kobuchwepheshe be-BOB kunikeza isisombululo esihle sokuthuthukiswa kobuchwepheshe bokufinyelela kwenethiwekhi ye-fiber optic. Ngemva kokwamukela ubuchwepheshe be-BOB, i-Optical Cat iyahluka ku-Optical Cat yendabuko endleleni yokupakisha yamamojula optical. Amamojula optical ashiselwe ngqo ku-I-ONUibhodi, ukwenza kube lula ukwakheka komkhiqizo, ukunciphisa izindleko zomkhiqizo, nokuthuthukisa ikhwalithi yomkhiqizo.
Ukusetshenziswa kobuchwepheshe be-BOB kukhula namuhla, okungathuthukisa ukuminyana kokuhlanganiswa kwesistimu ngaphandle kokwandisa izindleko eziningi, okuletha umfutho omkhulu wokwandisa umthamo nokunciphisa izindleko zezinhlelo zokuxhumana ze-optical. Ngokusetshenziswa kabanzi kobuchwepheshe be-BOB ku-EPON/GPONI-ONUamatheminali edivayisi, ngokuyisisekelo ithathe indawo yesikimu semojula ye-optical ezimele, iba uphawu olubalulekile lokuthuthuka okusheshayo nokusatshalaliswa okuvuthiwe ngezinga elikhulu kwamatheminali e-FTTH.
