Kwa mainjiniya apa intaneti, mwina sizachilendoSFPdoko, nthawi zambiri timasinthira, gawo la Optical, rauta, zida zosinthira media media zidalipo, komabe pali ogwiritsa ntchito ena samamvetsetsaSFPdoko, ndikuyika patsogolo zovuta zingapo, monga, kugwiritsa ntchito ndi chiyaniSFPdoko,
NdiSFPkhomo la optical fiber port, canSFPport turn RJ 45, etc. Pepala ili lidzayang'ana kwambiri kuyankha mafunso angapo omwe amakhudzidwa kwambiri ndi ogwiritsa ntchito.
Ndi chiyaniSFPdoko?Kodi ndi fiber outlet?Kodi ntchito ya chiyani?
SFPdoko ndi mawonekedwe kukwaniritsa gigabit photoelectric chizindikiro kutembenuka, ntchito yake yaikulu ndi kutembenuka chizindikiro ndi kufala deta, madoko ake kukumana IEEE 802.3ab mfundo (monga 1000 BASE-T), pazipita kufala mlingo mpaka 1000 Mbps (ena lophimbaSFPmadoko amathandizira 100 / 1000Mbps adaptive), motero amatchedwanso gigabit fiber port.
Ubwino wake ndi chiyaniSFPmadoko? Ndi zida ziti za netiweki zomwe zimagwiritsidwa ntchito kwambiri?
SFPdoko ndi la hot-plug I / O mawonekedwe (amatanthawuza mawonekedwe olowera / otulutsa), osinthika mwamphamvu, oyenera pazida zosiyanasiyana zama netiweki, mongaSFPOptical module, Gigabit switch, etc., ikhoza kusinthidwa ndi 1000 BASE-SX, 1000 BASE-LX / LH, 1000 BASE-ZX kapena 1000 BASE-BX 10-D / U doko.Komanso, aSFPdoko ndi pansi n'zogwirizana ndi 10/100/1000Mbps.Mwachidule, aSFPdoko lili ndi zabwino zinayi zazikulu:
● Kuthandizira pulagi yotentha, ikhoza kuchepetsa nthawi yokonzekera ndi kukonza;
● Doko limasinthasintha;
● Mapangidwe amphamvu amathandizira kudalirika;
● Yogwirizana ndi 10 / 100 / 1000Mbps.
1. TheSFPdoko laSFPOptical module
SFPOptical module ndi chipangizo cholumikizira chomwe chimasintha ma siginecha amagetsi a gigabit kukhala ma siginecha owoneka.Ndiwo muyezo wamakampani ang'onoang'ono komanso osinthika a gigabit optical transceiver Integrated module.Mapeto awiri aSFPOptical module: mapeto amodzi ndiSFPdoko, makamaka anaikapo lophimba, rauta, TV Converter ndi zipangizo zina maukonde kuti atembenuke magetsi siginecha kukhala kuwala kuwala kufala;mapeto ena ndi mawonekedwe a LC kapena mawonekedwe a RJ 45, omwe amagwiritsidwa ntchito makamaka kugwirizanitsa chingwe cha kuwala kapena chingwe cha intaneti kuti atumize deta.
2. TheSFPdoko la gigabit switch
Kusintha kwa GigabitSFPdoko akhoza olumikizidwa kwa mitundu yosiyanasiyana ya CHIKWANGWANI (monga mode limodzi ndi multimode CHIKWANGWANI) ndi maukonde jumper (monga Cat5e ndi Cat6) kukulitsa ntchito kusintha kwa maukonde lonse, koma gigabit lophimba.SFPdoko musanagwiritse ntchito liyenera kuyikidwa kayeSFPOptical module, ndiyeno gwiritsani ntchito fiber jumper ndi network jumper potumiza deta.Zosintha zonse zamabizinesi pamsika lero zili ndi ziwiriSFPmadoko omwe amatha kupanga ma topologies a annular kapena nyenyezi pakati pa nyumba zosiyanasiyana, pansi kapena madera kudzera mu zingwe monga ma fiber optical ndi ma jumper a network.
Kodi pali kusiyana kotaniSFPdoko ndi doko la RJ 45?
Ngakhale aSFPdoko ndi doko la RJ 45 onse ali ndi kufalikira kwakukulu kwa 1000Mbps, pali kusiyana pakati pawo.
1. Ntchito zosiyanasiyana
Mwachitsanzo, aSFPdoko pa switch liyenera kufanana naloSFPOptical module ndi kugwiritsa ntchito fiber jumper kuzindikira kufala kwa data;ndi RJ 45 doko pa chosinthira akhoza kuzindikira kufala deta mwachindunji kudzera pa netiweki chingwe.
2. Mtunda wotumizira ndi wosiyana
Doko la RJ 45 makamaka limayendetsa kufalitsa kwa data kudzera pa chingwe cha netiweki, mtunda wotalikirapo wa chingwe cha netiweki ndi 100 m, pomweSFPport iyenera kugwiritsa ntchitoSFPOptical module kuti agwirizane ndi optical fiber jumper kuti atumize, ndipo mtunda wake wodutsa kwambiri ndi mtunda wautali kwambiri waSFPOptical module, ndiko kuti, mamita 160.
SFPmadoko angagwiritsidwe ntchitoOLTndi kusintha zida.Shenzhen HDV Phoelectron Technology Co., Ltd. ndi opanga zida zama netiweki ndiOLTmndandanda ndi kusintha mndandanda.Panthawi imodzimodziyo, ili ndi gulu lamphamvu la hardware ndi mapulogalamu ndi gulu logulitsa kale ndi pambuyo pa malonda, omwe angapereke ntchito yabwino kwa makasitomala.
