25Gbps 10km Duplex LC SFP28 Transceiver

Inkcazo

Ii-transceivers ze-SFP28 zenzelwe ukusetyenziswa kwi-25-Gigabit Ethernet ikhonkco ukuya kwi-10km ngaphezu kwe-Fiber yeModi enye.

I-transceivers iyahambelana ne-INF-8431 kunye ne-SFF-8472. Ngolwazi oluthe vetshe, nceda ubhekisele kwi-INF-8431 kunye ne-SFF-8472.

Imephu yeMemori yoDigital Digital (Ihambisana ne-SFF-8472)

Ii-transceivers zibonelela ngomxholo wememori ye-ID ye-serial kunye nolwazi lokuxilonga malunga neemeko zokusebenza ezikhoyo nge-2-wire serial interface (SCL, SDA).

Ulwazi oluxilongayo ngolungelelwaniso lwangaphakathi okanye ulungelelwaniso lwangaphandle zonke ziyaphunyezwa, kubandakanywa ukujongwa kombane ofunyenweyo, ukujongwa kwamandla athunyelwayo, ukujongwa okucalanye ngoku, ukujonga umbane wobonelelo kunye nokujongwa kobushushu.

Imephu yedijithali yendawo yedatha yoxilongo ichaza njengokulandelayo (Ngolwazi oluthe vetshe, nceda ubhekisele kwi-SFF-8472).
