Yintoni imodyuli ye-SFP?

Imodyuli ye-SFP sisixhobo esibonakalayo esiguqula izibonakaliso zombane zegigabit zibe yimiqondiso ye-optical. Yimodyuli ye-industry-standard encinci kunye ne-pluggable gigabit optical transceiver enokuthi ifakwe kwi-SFP yezixhobo zenethiwekhi ezifana nokutshintsha, ii-routers, kunye nabaguquli beendaba. I-port isetyenziselwa ukudibanisa i-optical okanye i-copper network cables ukuhanjiswa kwedatha. Ngokuqhelekileyo sinokuyifumana kwiiswitshi ze-Ethernet, iirotha, iifirewall kunye namakhadi ojongano lwenethiwekhi.

Yintoni izibuko le-SFP?

Njengoko kukhankanyiwe ngasentla, izibuko SFP zixhaphake afumaneka izixhobo womnatha ezifana switsha, imizila, converters eendaba, njl Ngaba ngokwenene uyazi izibuko SFP? I-port ye-SFP isetyenziselwa ukuguqulwa kwesignali kunye nokuhanjiswa kwedatha. I-port yayo ihambelana nomgangatho we-IEEE 802.3ab (ofana ne-1000BASE-T), kwaye umgama ophezulu wokuhambisa unokufikelela kwi-1000 Mbps (i-port ye-SFP yokutshintsha isekela i-100/1000 Mbps).

Izinto ezilungileyo ze-SFP port

I-port ye-SFP yi-interface ye-I / O eshushu-eguqukayo (ebhekisela kwi-interface yegalelo / i-output interface), ene-flexibility eqinile kwaye ifanelekile kwiimveliso ezahlukeneyo, ezifana ne-1000BASE-SX, 1000BASE-LX / LH, 1000BASE-ZX okanye I-1000BASE -BX10-D/U izibuko zinokutshintshwa, kwaye i-port ye-SFP ihambelana ngasemva, ixhasa 10/100/1000Mbps.

Izibuko le-SFP lokutshintsha kweGigabit

I-port ye-SFP yokutshintsha kwe-Gigabit ingasetyenziselwa ukwandisa umsebenzi wokutshintsha kwenethiwekhi yonke ngokudibanisa iintlobo ezahlukeneyo zemicu ye-optical (ezifana ne-mode eyodwa kunye ne-multi-mode fiber) kunye ne-jumpers yenethiwekhi (njenge-Cat5e kunye ne-Cat6), kodwa i-port ye-SFP ye-Gigabit switch Imodyuli ye-SFP ebonakalayo kufuneka ifakwe phambi kokusetyenziswa, kwaye emva koko isebenzise i-fiber jumpers kunye ne-network jumpers yokuhanjiswa kwedatha. Kule mihla, zonke iinguqu zenqanaba loshishino kwimarike zineezibuko ezimbini ze-SFP, ezinokwakha ikhonkco okanye i-star network topology phakathi kwezakhiwo ezahlukeneyo, imigangatho okanye imimandla ngokudityaniswa kweentambo ezinjengeentambo zokukhanya kunye neejumpi zenethiwekhi.
