Kune mainjiniya etiweki, pamwe hazvizivikanweSFPchiteshi, isu kazhinji mukuchinja, optical module, router, midhiya inoshandura network michina yakaona kuvepo kwayo, asi pachine vamwe vashandisi vasinganyatso nzwisisaSFPport, uye nekuisa pamberi akatevedzana matambudziko, akadai, chii chiri kushandiswaSFPchiteshi,
NdiyoSFPport an optical fiber port, canSFPport turn RJ 45, zvichingodaro. Bepa rino richatarisa pakupindura mibvunzo yakati wandei inonyanya kunetsa nevashandisi.
Chii chinonziSFPchiteshi?Iyo fiber outlet?Basa rei?
SFPport is an interface yekuzadzisa gigabit photoelectric signal conversion, basa rayo guru nderekushandura chiratidzo uye kuendesa data, zviteshi zvayo zvinosangana neIEEE 802.3ab zviyero (zvakadai se1000 BASE-T), huwandu hwekutumira hunosvika ku1000 Mbps (imwe chinja.SFPports inotsigira 100 / 1000Mbps inogadzirisa), saka inonziwo gigabit fiber port.
Ndezvipi zvakanakira theSFPports?Ndeipi network midziyo inowanzoshandiswa?
SFPchiteshi ndechekupisa-plug I / O interface (inoreva yekupinza / yekubuda interface), ine simba inoshanduka, yakakodzera kune akasiyana network zvishandiso, senge.SFPOptical module, Gigabit switch, nezvimwewo, inogona kuchinjana ne1000 BASE-SX, 1000 BASE-LX / LH, 1000 BASE-ZX kana 1000 BASE-BX 10-D / U chiteshi.Mukuwedzera, theSFPport inodzika pasi inoenderana uye inotsigira 10/100/1000Mbps.Muchidimbu, theSFPport ine mabhenefiti mana makuru:
● Tsigira inopisa plug, inogona kuderedza kuiswa nekugadzirisa nguva yekugadzirisa;
● Chiteshi chengarava chinochinjika;
● Kugadzirwa kwakasimba kunowedzera kuvimbika;
● Inoenderana ne10 / 100 / 1000Mbps.
1. TheSFPport yeSFPOptical module
SFPoptical module chishandiso chinoshandura gigabit magetsi masaini kuita masaini masaini.Ndiyo indasitiri yakajairika diki uye pluggable gigabit optical transceiver integrated module.Magumo maviri eSFPOptical module: imwe mugumo ndeyeSFPport, inonyanya kuiswa muchinja, router, midhiya inoshandura uye mamwe maturusi etiweki kushandura masaini emagetsi kuita masaini masaini ekutapurirana;imwe magumo ndeye LC interface kana RJ 45 interface, iyo inonyanya kushandiswa kubatanidza optical fiber kana network tambo yekufambisa data.
2. TheSFPchiteshi chegigabit switch
Gigabit chinjaSFPchiteshi chinogona kubatana nemhando dzakasiyana dzefiber (senge single mode uye multimode fiber) uye network jumper (yakadai seCat5e uye Cat6) kuwedzera basa rekuchinja retiweki yese, asi gigabit switch.SFPport isati yashandiswa inofanira kutanga yaiswaSFPOptical module, wobva washandisa fiber jumper uye network jumper yekufambisa data.Ese mabhizinesi anochinja pamusika nhasi ane angangoita maviriSFPzviteshi zvinogona kuvaka annular kana nyeredzi network topologies pakati pezvivakwa zvakasiyana, pasi kana nzvimbo kuburikidza netambo dzakadai seoptical fibers uye network jumpers.
Chii chakasiyanaSFPchiteshi uye RJ 45 chiteshi?
Kunyangwe iyoSFPchiteshi uye RJ 45 chiteshi zvese zvine mwero wekutapurirana we1000Mbps, pane misiyano pakati pawo.
1. Zvikumbiro zvakasiyana
Somuenzaniso, theSFPport pane switch inoda kufananidzwa nayoSFPOptical module uye kushandisa fiber jumper kuona kutapurirana data;uye iyo RJ 45 chiteshi pane switch inogona kuona kuendesa data zvakananga kuburikidza netiweki tambo.
2. Kuendesa kure kwakasiyana
RJ 45 port inonyanya kufambisa data kuburikidza netiweki tambo, kureba kwekufambisa kwetambo yetiweki ndeye 100 m, nepoSFPport inoda kushandisa iyoSFPoptical module yekubatanidza kune optical fiber jumper yekutapurirana, uye iyo yakanyanya kureba yekufambisa kureba ndiyo yakanyanya kuremerwa kureba kweiyoSFPOptical module, kureva, 160 metres.
SFPports inogona kushandiswa kuneOLTuye chinja midziyo.Shenzhen HDV Phoelectron Technology Co., Ltd. inogadzira netiweki michina ineOLTseries uye chinja series.Panguva imwecheteyo, ine yakasimba hardware uye software timu uye pre-kutengesa uye mushure-yekutengesa timu, iyo inogona kupa yakanakisa sevhisi kune vatengi.
