Iyini imojuli ye-SFP?
I-SFP isifinyezo sephakheji elincane elixhumeka.Kuyimojula ye-Optical ecwebezelayo, eshisayo exhumekayo yokuxhumana ngocingo nezinhlelo zokusebenza zokuxhumana ngedatha.Imojula ye-SFP Optical ingabhekwa njengenguqulo ethuthukisiwe ye-GBIC Optical module.Ngokungafani nama-GBIC ane-SC fibre interfaces, ama-SFP eza ne-LC interfaces (nakuba kukhona futhi amamojula e-SFP ane-SC interfaces) futhi anosayizi womzimba ocishe ube uhhafu kuphela wama-GBIC, okuvumela ama-SFP ukuthi onge isikhala esiningi.I-SFP ixhuma ibhodi lomama lamadivayisi enethiwekhi (njengamarutha, amaswishi, iziguquli zemidiya, noma amadivaysi afanayo) kumakhebuli abonakalayo noma izintambo.Ngasikhathi sinye, i-SFP iyincazelo yezimboni evame ukusetshenziswa esekelwa abahlinzeki abaningi bedivayisi yenethiwekhi.Iklanyelwe ukusekela i-SONET, i-Gigabit Ethernet, i-Fiber Channel, nezinye izindinganiso zokuxhumana.Umumo ukhonjiswe emfanekisweni olandelayo
Ukumisa
Imojula ye-SFP Optical ayilawulwa yinoma yiluphi uhlelo olujwayelekile olusemthethweni, kodwa ilawulwa yisivumelwano sezizwe ngezizwe (MSA) phakathi kwezimbangi.I-SFP yakhelwe ngokwesixhumi esibonakalayo se-GBIC futhi ifinyelela ukuminyana kwembobo okuphezulu kune-GBIC (inani le-Optical module per sentimitha emaphethelweni ebhodi lomama), yingakho i-SFP ibizwa nangokuthi i-mini GBIC.Iphakheji elincane elihlobene Imoduli ye-Optical inosayizi ofana ne-SFP, kodwa idayiswa ebhodini lomama njengephini kunokuba ifakwe ku-slot yekhadi eseceleni.
Kodwa-ke, ekusetshenzisweni okusebenzayo, abanye abakhiqizi bedivaysi yenethiwekhi basebenzisa indlela eyinhloko ukuze baphule ukuhambisana ne-SFP "yomhlaba wonke", okungukuthi, ukwengeza inqubo yokuqinisekisa ku-firmware yedivayisi ukuze idivayisi ikwazi ukunika amandla imojula yayo ye-Optical kuphela.
Izinhlobo ezahlukene ze-SFP
Kunezinhlobo eziningi ezahlukene zama-transmitter nabamukeli bamamojula e-SFP athengiswa emakethe namuhla.Le ndlela ivumela abasebenzisi ukuthi bakhethe imojuli ye-Optical efanelekile kusixhumanisi ngasinye esihlukile.Isibonelo, ezinhlotsheni zokusebenzelana zamanje, ukudluliswa kungahlukaniswa kube imodi eyodwa noma i-multimode ngokusekelwe ezinhlotsheni zefayibha ezihlukene.
Njengoba kukhonjisiwe emfanekisweni ongenhla, lesi sithombe sibonisa imojuli yefiber eyodwa yesixhumi esibonakalayo se-SC
Njengoba kukhonjisiwe emfanekisweni ongenhla, lena imojula yefayibha kabili yesixhumi esibonakalayo se-LC
Ukwakhiwa kwe-SFP
Ukwakheka kwesakhiwo: ikakhulukazi eyakhiwe enye (i-BOSA yefayibha eyodwa; i-TOSA+ROSA yefayibha ephindwe kabili), ehlanganiswe nebhodi le-PCBA negobolondo, futhi ifakwe izindandatho zokudonsa, amabhande, izingxenye zokuvula, namapulaki erabha.Ukuze uhlukanise kangcono amaza amaza okukhipha kanye nokwamukela kusukela ekubukeni, imibala ehlukene yokudonsa indandatho ngokuvamile idizayinelwe ukuhlukanisa izinhlobo zepharamitha zemojuli.Isibonelo, ku-LC single fiber interface, indandatho yokudonsa eluhlaza okwesibhakabhaka ingu-1310nm, indandatho yokudonsa ensomi ingu-1490nm, njalonjalo.
Imojula ye-SFP ekhiqizwe yi-Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. iwumkhiqizo othengiswa kakhulu.Ngaphezu kwalokho, kukhona nokuxhumana okudumile kwe-Optical module, i-plugable Optical module, i-1x9 Optical module, i-dual core Optical module neminye imikhiqizo yemojula yezinhlobo ezahlukene.Yamukela wonke umuntu odingayo ukuze abe nokuqonda komkhiqizo.I-Shenzhen Haidwiwei Optoelectronics Technology Co., Ltd. ingahlinzeka ngethimba lenkonzo yezobuchwepheshe eliqeqeshiwe ukuze likusebenzele.
