Kwiinjineli zenethiwekhi, ngokuqinisekileyo akukho nto yasemzini kuyoSFPizibuko, sihlala sihlala kwitshintsha, imodyuli yokubona,umzila, izixhobo zenethiwekhi zokuguqula imidiya zabona ubukho bayo, kodwa kusekho abanye abasebenzisi abangayiqondi ncamSFPport, kwaye ubeke phambili uthotho lweengxaki, ezinje, yintoni ukusetyenziswa kweSFPizibuko,
Ingaba iSFPizibuko i-optical fiber port, canSFPi-port turn RJ 45, njl. Eli phepha liya kugxininisa ekuphenduleni imibuzo emininzi exhalabisa kakhulu abasebenzisi.
Yintoni iSFPizibuko? Ingaba yifiber outlet? Yintoni umsebenzi?
SFPizibuko lujongano lokufikelela kwigigabit photoelectric ukuguqulwa kwesiginali, umsebenzi wayo ophambili kukuguqulwa komqondiso kunye nokuhanjiswa kwedatha, amazibuko ayo adibana nemigangatho ye-IEEE 802.3ab (efana ne-1000 BASE-T), izinga logqithiso logqithiso ukuya kuthi ga kwi-1000 Mbps (ezinyetshintshaSFPamazibuko axhasa i-100 / 1000Mbps eguqukayo), ngoko ikwabizwa ngokuba yi-gigabit fiber port.
Ziziphi iingenelo zeSFPizibuko?Zeziphi izixhobo zothungelwano ezidla ngokusetyenziswa?
SFPizibuko lelojongano lweplagi eshushu ye-I / O (ibhekisa kujongano lwegalelo / imveliso), enokubhetyebhetye okunamandla, ilungele izixhobo ezahlukeneyo zenethiwekhi, njenge.SFPimodyuli yokubona, iGigabittshintsha, njl., inokutshintshwa kunye ne-1000 BASE-SX, 1000 BASE-LX / LH, 1000 BASE-ZX okanye 1000 BASE-BX 10-D / U port. Ukongeza, iSFPizibuko liyahambelana ezantsi kwaye lixhasa i-10/100/1000Mbps. Ngamafutshane, iSFPizibuko lineenzuzo ezinkulu ezine:
● Inkxaso yeplagi eshushu, inokunciphisa ixesha lokulawula ukufakela kunye nokugcinwa;
● Izibuko liyabhetyebhetye;
● Uyilo olomeleleyo lukhulisa ukuthembeka;
● Iyahambelana ne-10 / 100 / 1000Mbps.
1. ISFPizibuko leSFPimodyuli yokubona
SFPImodyuli ye-optical sisixhobo sojongano oluguqula imiqondiso yombane yegigabit ibe yimiqondiso yokubona. Ingumgangatho woshishino oluncinci kunye ne-pluggable gigabit optical transceiver module edibeneyo. Iziphelo ezimbini zeSFPimodyuli yokubona: isiphelo esinye siSFPizibuko, ifakwe ikakhulu ngaphakathitshintsha, umzila, isiguquli semidiya kunye nezinye izixhobo zenethiwekhi ukuguqula imiqondiso yombane ibe yimiqondiso ye-optical yokudluliselwa; esinye isiphelo yi-LC interface okanye i-RJ 45 interface, esetyenziswa kakhulu ukuqhagamshela i-fiber optical okanye intambo yenethiwekhi yokuhanjiswa kwedatha.
2. ISFPizibuko legigabittshintsha
GigabittshintshaSFPizibuko linokudityaniswa kwiintlobo ezahlukeneyo zefiber (ezifana nemowudi enye kunye nefayibha yemultimode) kunye ne-jumper yenethiwekhi (efana neCat5e kunye neCat6) ukwandisa umsebenzi wokutshintsha kwenethiwekhi yonke, kodwa igigabittshintshaSFPizibuko phambi kokusetyenziswa kufuneka kuqala kufakweSFPimodyuli ye-optical, kwaye emva koko usebenzise i-fiber jumper kunye ne-network jumper yokusasazwa kwedatha. Lonke utshintsho lwamashishini kwimarike namhlanje lunezimbini ubuncinciSFPamazibuko anokwakha annular okanye star womnatha topology phakathi kwezakhiwo ezahlukeneyo, imigangatho okanye iindawo ngokusebenzisa iintambo ezifana imicu optical kunye jumpers womnatha.
Yintoni umahluko phakathiSFPizibuko kunye ne-RJ 45 port?
Nangona iSFPizibuko kunye ne-RJ 45 port zonke zinezinga eliphezulu lokudluliselwa kwe-1000Mbps, kukho ukungafani phakathi kwabo.
1. Izicelo ezahlukeneyo
Umzekelo, iSFPizibuko kwitshintshakufuneka ihambelane nayoSFPimodyuli yokubona kunye nokusebenzisa i-fiber jumper ukuqonda ukuhanjiswa kwedatha; kunye ne-RJ 45 port kwi-tshintshainokuqonda ukuhanjiswa kwedatha ngokuthe ngqo ngentambo yenethiwekhi.
2. Umgama wothumelo wahlukile
Izibuko le-RJ 45 ikakhulu lihambisa idatha ngentambo yenethiwekhi, owona mgama mkhulu wothumelo lwentambo yenethiwekhi yi-100 m, ngelixaSFPizibuko kufuneka usebenzise iSFPimodyuli yokubona ukudibanisa kwijumpi yefiber optical yokuhanjiswa, kwaye umgama wayo omkhulu wothumelo ngowona mgama mkhulu wothumelo weSFPimodyuli ye-optical, oko kukuthi, i-160 yeemitha.
SFPamazibuko anokusetyenziswa kuwoOLTkwayetshintshaizixhobo. I-Shenzhen HDV Phoelectron Technology Co., Ltd. ngumenzi wezixhobo zenethiwekhi kunyeOLTseries kunyetshintshauthotho. Ngelo xesha, ine-hardware eyomeleleyo kunye neqela lesoftware kunye neqela lokuthengisa kwangaphambili kunye neqela emva kokuthengisa, elinokubonelela ngeyona nkonzo ilungileyo kubathengi.
