Iyini imojuli ye-SFP?

Imojula ye-SFP iyisisetshenziswa esibonakalayo esiguqula amasiginali kagesi we-gigabit abe amasignali optical. Kuyimojula ye-gigabit optical transceiver esezingeni elijwayelekile embonini engaxhunywa ku-SFP yezinto zokusebenza zenethiwekhi ezifana namaswishi, amarutha, neziguquli zemidiya. Imbobo isetshenziselwa ukuxhuma izintambo zenethiwekhi ye-optical noma yethusi ukuze kudluliswe idatha. Ngokuvamile singayithola kumaswishi e-Ethernet, amarutha, ama-firewall namakhadi esixhumi esibonakalayo senethiwekhi.

Liyini ichweba le-SFP?

Njengoba kushiwo ngenhla, izimbobo ze-SFP zivame ukutholakala emishinini yenethiwekhi efana nokushintsha, ama-routers, iziguquli zemidiya, njll. Ingabe uyazi ngempela izimbobo ze-SFP? Imbobo ye-SFP isetshenziselwa ikakhulukazi ukuguqulwa kwesignali nokudlulisa idatha. Imbobo yakhona ihambisana nezinga le-IEEE 802.3ab (elifana ne-1000BASE-T), futhi ibanga lokudlulisa eliphezulu lingafinyelela ku-1000 Mbps (imbobo ye-SFP yokushintsha isekela u-100/1000 Mbps).

Izinzuzo ze-SFP port

Imbobo ye-SFP iyisixhumi esibonakalayo se-I/O esishintshashintshashintshayo esishisayo (esisho isixhumi esibonakalayo sokufaka/sokukhiphayo), esinokuguquguquka okuqinile futhi silungele imikhiqizo ehlukahlukene, njenge-1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX noma Amachweba angu-1000BASE -BX10-D/U angashintshwa, futhi ichweba le-SFP lihambisana emuva, lisekela 10/100/1000Mbps.

Ichweba le-SFP le-Gigabit switch

Imbobo ye-SFP ye-switch ye-Gigabit ingasetshenziselwa ukwandisa umsebenzi wokushintsha wenethiwekhi yonke ngokuxhuma izinhlobo ezihlukahlukene zezintambo ezibonakalayo (ezifana nemodi eyodwa kanye ne-multi-mode fiber) kanye nezixhumi zenethiwekhi (ezifana ne-Cat5e ne-Cat6), kodwa imbobo ye-SFP yeswishi ye-Gigabit Imojula yokubona ye-SFP kufanele ifakwe ngaphambi kokusetshenziswa, bese isebenzisa ama-fiber jumpers kanye nezixhumi zenethiwekhi ukuze kudluliselwe idatha. Namuhla, wonke amaswishi ezinga lebhizinisi emakethe okungenani anezimbobo ezimbili ze-SFP, ezingakha indandatho noma inkanyezi yenethiwekhi ye-topology phakathi kwezakhiwo ezahlukene, izitezi noma izifunda ngokuxhunywa kwezintambo ezifana namafiber optical kanye nama-jumper enethiwekhi.
