I-2.5G SFP iyimojula yokubona enezinga lokudlulisela elifinyelela phezulu2.5Gbps. Yamukela i-SFP (Ama-plugables we-Form-factor Amancane) ifomethi yokupakisha, izici zokuziqhayisa njengosayizi omncane, ukusetshenziswa kwamandla okuphansi, nokuthembeka okuphezulu.
Le mojula isekela amabanga okudlulisela ahlukahlukene, asukela kumakhulu amamitha kuya kumashumi amakhilomitha, kuye ngohlobo lwentambo yesichibi esetshenzisiwe. Isibonelo, imojuli ye-2.5G ye-multimode optical ingabhangqwa nayoOM2ama-patch cords, afinyelela ibanga eliphezulu lokudlulisela elifika ku-500m. Ngakolunye uhlangothi, imojula ye-2.5G yemodi eyodwa ye-optical ingabhangqwa nezintambo zesichibi zemodi eyodwa ye-OS2, ifinyelele ibanga eliphezulu lokudlulisela elifinyelela ku-160km.
I-2.5G SFP optical module isetshenziswa kabanzi ezindaweni ezihlukahlukene zokudlulisela ezifanaI-Ethernet,I-SDH,I-SONET, futhiFC. Ikakhulukazi ezimeni ezifana namanethiwekhi endawo yedolobha elikhulu,amanethiwekhi wendawo,amanethiwekhi endaweni ebanzi,amanethiwekhi ekhampasi, futhiizikhungo zedatha ezincane kuya ezimaphakathi, uhla lwayo olubanzi lwamabanga okudlulisela lungahlangabezana nezidingo zezimo ezihlukene zohlelo lokusebenza.
